Din Rail Switching Mode Power Supplies air conditioners work in turn and set the temperature?

With the continuous development of network information technology, the environmental parameters in the computer room where the server is stored are also becoming more and more important. Some small and medium-sized computer rooms keep the temperature inside the equipment room within a certain range. Not only one air conditioner is installed, but also a spare air conditioner is stored. The purpose is to prevent malfunction of the air conditioner in operation or other reasons. It is necessary to turn on the backup air conditioner. However, it is impossible for the computer room management personnel to stay in the computer room for 24 hours. In order to reduce the burden on the computer room management personnel, the air conditioner intelligent switcher can solve this problem well.
The air conditioner switch can control two air conditioners at the same time to realize functions such as air conditioner caller self-start, timed temperature control switch, failover, and fault alarm. Applicable to computer room, outdoor base station, archives, warehouse and other places. Its principle of using infrared code to switch air conditioners makes the device compatible with all brands of air conditioners on the market.
First, the air conditioner switch concept
The air conditioner dual-machine switcher is a kind of intelligent air-conditioner controller, which can detect and control the running state of the air-conditioner, and control according to the preset air-conditioner operation, shutdown and combined behavior, with automatic call start function, cycle switching, temperature control, Timing control, relay output and other functions. The purpose of protecting equipment, saving energy and reducing consumption, improving the efficiency of computer room management and extending the service life of air conditioners has been achieved. This product is widely used in civil, small and medium-sized computer rooms, communication stations, UPS machine rooms in all types of cabinets. Mainly used for switching control of two air conditioners.

VR成潮人新寵，呢啲數據抵得得pick一下！

《Raw Data》系當前公認最優秀嘅VR遊戲之一，喺2016年上市嘅一個月內就取得了一百萬美元嘅營收，如果你曾經光顧過街頭巷尾嘅VR體驗店，極有可能已經被推薦過該遊戲。玩家戴上VR頭盔，即可扮演“配槍嘅神職人員”或“舞刀弄箭嘅未來忍者”等角色，喺虛擬世界中閃轉騰挪和戰友協同作戰，守護對方嘅背脢，擊退來犯嘅機械敵人。

3A大作《Raw Data》

除開《Raw Data》咁樣專爲VR全新設計嘅遊戲，也有《生化危機7》咁樣嘅跨界力作，後者喺發售半個月內使用PSVR進行體驗嘅用戶即超過了10萬之數，約占該遊戲當其時總用戶嘅10%。時至今日，官方根據玩家主動分享嘅數據統計《生化危機7》嘅VR玩家已經超過了50萬。《生化危機》系列系營造氣氛嘅優秀代表，配合上VR嘅沈浸感體驗，讓諸多老司機驚呼嚇人，因此喺遊戲社區獲得了極高嘅評價。

《生化危機7》嘅正確打開方式

另一款抵得得關注嘅VR作品系《輻射4》VR公司版，喺內容上和此前嘅PC版本冇太大區別主要系進行了VR顯示和操作嘅適配，上市兩個月以來就取得了超過10萬份嘅銷量，從營收來睇可以稱得上系當其時最暢銷嘅VR遊戲。但咁樣嘅銷量主要系基于原版遊戲嘅號召力，俗稱情懷，而非其作爲VR遊戲嘅優秀程度。即管《輻射4VR》彰顯了B社嘅執行力，畢竟要將一個複雜嘅RPG遊戲VR化並非易事，但脫開VR這個細分領域而言，十萬這個銷量相對原版喺發售首日超過一千祈份嘅出貨量來說幾乎唔抵得一提。

從主要嘅VR遊戲分發平台Steam泄漏出嘅一份“部分VR獨占遊戲”銷量數據來睇，《生果忍者VR》咁樣嘅老少皆宜知名應用截止2018年7月嘅銷量尚未超過8萬份，而喺國外VR粉絲中比較流行免費VR社交遊戲《Rec Room》排行最高約30萬份，HTC Vive發布時就展示了Demo嘅《Job Simulator》爲約20萬份。即管如《Beat Saber》咁樣嘅社交網絡寵兒未被列入該統計，但唔得否認嘅系，總體來說VR遊戲內容嘅發展並唔如預期，可以被稱爲爆款嘅VR遊戲屈指可數。

網紅遊戲《Beat Saber》

優質內容嘅缺失，也成了諸多玩家閑置重金購買而來嘅VR公司設備嘅主要原因，當然VR設備和內容系一個典型嘅“先有雞仲系先有蛋”問題。喺頂級嘅三大頭顯中，自成一家嘅索尼PSVR于8月中旬累計銷量剛突破300萬台，這主要得益于龐大嘅PlayStation群體，即將結束生命周期嘅PS4銷量已然超過8000萬台。喺2017年HTC Vive和Oculus Rift兩家嘅銷量喺30萬台級別，以HP、三星爲代表嘅微軟系頭顯則系10萬級別嘅。目前市售産品中配置效果至好嘅Vive Pro，由于發售時間唔足半年，喺市場整體占比較小，但根據Valve官方對近半年接入Steam硬件統計，Vive嘅份額已經連氣四個月上升，至到了1.81%，睇落雖然Vive Pro價格高企（全套超過一萬人民幣），仍系硬核發燒友嘅首選。從Steam平台這份數據來睇，市場份額最高嘅仍系Oculus Rift（46.18%）,HTC Vive以44.35%緊隨其後。抵得得注意嘅系市場占有率一向頗爲低迷嘅微軟系頭顯雖然發布已近一年，但近來接入Steam平台嘅份額正逐步上升，從去年底嘅4.35%幾乎系一路升到6.41%。這可能與其銷售策略有關，如HP嘅頭顯喺美亞嘅常規售價唔到300美金，雖然綜合性能要低于Oculus和Vive，但玩玩《Beat Saber》仲系穩穩嘅。下圖爲大陸VR媒體映維網整理嘅Steam平台VR頭顯市場份額，有興趣嘅同學可以深入琢磨一下。

Steam平台VR頭顯市場份額

再睇落移動VR公司方面，作爲三星旗艦手機配套嘅Gear VR喺2016年就有著約450萬嘅出貨量，與之對比谷歌嘅Daydream爲20萬級別，但二者喺2017年都有著唔同程度嘅下滑，喺2018年Gear VR已經缺席了三星自家嘅手機發布會。于2018年4月正式上市嘅Oculus Go作爲“廉價”嘅VR一體機定價199美元，Q2銷量約爲30萬台，撐起了主流頭顯嘅銷售數據。該設備只支持三軸定位，主要用于浏覽和簡單嘅遊戲，即管該數據並未包括其喺大陸銷售嘅孿生版小米VR，但從目前黃牛普遍嘅起價行爲來睇，小米VR一體機嘅出貨量可能並唔太高，小米VR團隊此前嘅定調系目標十萬台。作爲移動VR當前旗艦嘅HTC Vive Focus定價3999元，于2017年底開售，目前並冇牙力嘅銷量聲氣。根據官方聲氣與偉仕佳傑簽下了十億人民幣嘅訂單，後者系IT數碼産品領域嘅重要經銷商，若以單台價格2500元嘅經銷商價格來粗略斷估，嗰個約合40萬台，當然這並唔直頭等同于消費者嘅購買量。

A Big Step for VR Online Games, Intel Announces Large Scale Multiplayer VR Scenarios

Recently, a number of vendors announced their own solutions for using VR in large scenes simultaneously. It is expected that this year's VR online games may be. Recently, Intel announced a series of VR 360 software solutions, which, through cooperation with The Glimpse Group, jointly created a multi-person solution with the same large space.

The Basics of HDMI Cables

The High Definition Multimedia Interface (HDMI) is a digital substitute for analog video standards. It is a compact interface for audio and visual electronic exchange. It transfers uncompressed and compressed digital audio files and uncompressed video output files from an HDMI-compliant source device to a compatible computer monitor, digital audio device, video projector, digital television etc.
There are a variety of HDMI cables uniquely suitable for uncompressed PC or TV video format, enhanced high-definition and 3D video signals, 8 channels of uncompressed and compressed digital audio data, a Consumer Electronics Control (CEC) connection and Ethernet connected data. HDMI executes Consumer Electronics Association (CEA) and Electronic Industries Alliance (EIA) -861 standards.

HDMI connectors are of five types: A/B (defined in 1.0 specifications), C (defined in 1.3), and D/E defined in 1.4).
The type A HDMI connector has 19 pins. Its bandwidth supports SDTV, HDTV and EDTV modes. It is electrically matched to single-link digital visual interface- digital (DVI-D).
The type B HDMI connector has 29 pins. It can carry 6 differential pairs tailored for future high-resolution displays. It electrically complies with DVI-D with dual link.
The type C is a mini connector. It has 19 pins. It is smaller than type A. The basic difference is that its positive signals of differential pairs are traded with corresponding shields. The type C may be used as a type A using a type A-C cable.
The type D is a micro connector with 19 pins just like type A and C. It is very small. Again the pin assignment is slightly different from A and C.
The automotive system uses type E HDMI connector. It has a locking stub so that it does not become loose due to a vibrating machine. There is a shell that shields it from moisture and dust. It needs a relay connector for getting connected to the automotive.

There are two categories of cables defined by HDMI 1.3. The category 1 is a standard cable. It is tested at 74.5 MHz. The category 2 cables are high-speed cables. It is tested at 40 MHz. It gives a higher resolution. The length of such cables depends on conducting materials and construction quality. These characteristics affect attenuation. Category 1 cables with 5 meter length use thinner conductors. A longer cable needs a thicker connector with better quality construction.

One of the hottest opportunities for businesses and marketers today is connecting with the billions of cell phone users through mobile apps.
Both Apple's iPhone and Google's Android are gaining more and more users every day, users with their wallets ready to spend money and ready to use apps to find what they are looking for right from their phones instead of desktop or laptop computers.
This article explains how to take advantage of these opportunities using app builders now available through Main Street Marketing Machines.
Face it, unless you've been living under a rock, you either own or know someone who owns a smart phone. Chances are pretty good that you've seen an Apple iPhone or Google Android phone. With billions of users and millions of downloads of mobile apps for these phones, you can see the opportunity for businesses.
Build an app to showcase your business, get yourself listed in mobile search rankings and outsmart, outposition and out market your competition! In fact, if your business is not being found in mobile search now, it's going to virtually completely disappear from your target customer's radar in the next few years.

So, how can you stop this from happening? Easy, get yourself a personalized mobile app for your business. But how do you do it you ask?
Well, there are three major ways of going about it.
1) You can hire a professional app developer and pay tens of thousands of dollars and wait in line for them to get around to creating your app. You can find dozens of developers online just by doing a Google search for "iPhone App Developers."
2) You can get yourself a copy of Apple's app development software and the Google Android developer kit and spend some serious quality time learning how to do it yourself. It's readily available, just Google search iPhone Developers Kit and follow the instructions Apple gives you.
3) Finally, you can use a template builder to build your personalized app quickly and painlessly.
There are several template builders for apps available on the market now, but the easiest for businesses and marketers that I've found is the iPhone and Android app builders available as part of Main Street Marketing Machines from Mike Koenigs and the good folks over at Traffic Geyser.
If you want to check out all the options, then just Google "iPhone App Building Templates"
These template programs like Main Street Marketing Machines usually grew out of some other would-be developer trying to make the development process easier.
MSMM for example evolved from a beta test called Firepower that I participated in. The system is really designed as a complete done for you marketing system to allow Internet Marketers to get paid by local businesses for helping those businesses to get found online and get new customers from that, but the iPhone and Android development templates are awesome resources for those wanting to design their own mobile apps.

These mobile app builders allow you to build your own apps or create them for others to run on the iPhone and Android.
If you are thinking about doing your own App or you finally reallize the importance of creating a mobile app for your business and getting it found in mobile and local searches, you should check out the free videos about Main Street Marketing Machines that I link to in the resource box below or at least hop on Google and start searching for those who can aid you in creating your mobile apps.

Android TV and Apps

Did you hear about the new Android TV? These televisions have caught the fancy of people and offers a new way to watch television. Be it playing games or browsing the net, an Android TV offers a lot.
However, Android apps haven't been that easy to make. So, if you are looking forward for developers to make apps for Android TV as well, you need to consider certain aspects first.
Here is a look at the difficulties developers face when designing an Android TV box app.
Developers work hard, putting in lot of thoughts, time and energy into making a great product. However, many developers fail to take a few key steps that can help them create that magical app. It has to be remembered that almost everyone has a smartphone today. While there are millions of apps for the Android smart phones, apps which are specifically designed for playing with Android TVs are still not that high in number. Developers need to meet different challenges to design newer and better apps. Creating the right product and managing to get loyal customers requires a good strategy.

All about apps
The app icon and the user interface should be clean and be easy to use. Users begin to form opinions about the app once they download it. Developers should read the reports from users to find out the requirements.
Determination of the demographics
Developers get vast information about app users and usage from users. If you are thinking to create a new app, you need to think like a marketer and critically analyze the market to determine your target demographic. For instance, if your app is targeted at low-income people within a particular age group, why would you concentrate on building apps for iOS?
Of course, if you do that, you will spend more money and energy building apps for the wrong audience. Android TV apps in particular, need to be more appealing.
Investing on metrics that can be quantified
Most developers don't understand how to make proper use of app usage data. As a developer, you ought to read usage of app data by users on a daily basis. Developers should also use reports which show how effective their ads are and how much they can possibly monetize it.
Network for discoverability

Networking with other app developers is a great way by which you can take your apps to even greater heights. Utilize social networks and also guest blog about your app in other app developers' blogs. You can also simply attend seminars or webinars where app development is the topic. Building relationships in the right circles can offer results that you never anticipated.
Conclusion
Developers require extra effort and research to come out with something innovative. If they are developing an app for an Android TV, they need to first know the audience well to understand the needs and preferences. There are several ways of doing this. As a developer, the end product should actually be user friendly for the users.

Portable Bluetooth Speakers - Benefits and Uses

Portable Bluetooth speakers make it effortlessly easy to listen to your favorite music on the go. Working on the same technology (Bluetooth) that allows you to send and receive files and data on your cellphone wirelessly, these portable Bluetooth speakers are easy to use, easy to set up, lightweight, and perfect for anyone who likes to carry his music with him.
I can think of dozens of scenarios where a set of portable Bluetooth speakers would be handy. Recently, on a picnic with friends, I found myself craving some good music. While I had plenty of songs in my iPod, I could listen to them only through my headphones. But at that moment, I wanted music to be a shared experience, to listen to it along with all my friends. In such a scenario, a set of battery powered portable Bluetooth speakers would have been very handy. Just plug it in into your iPod, and enjoy your favorite tunes with friends or a loved one.

And really, that is the primary job of these portable speakers: to make music more social. In terms of portability, nothing can beat a pair of earphones. But if you want to share the music experience with others, you will need to invest in a set of Bluetooth speakers. Imagine camping with a loved one, lying under the stars, and listening to your favorite tunes. This is possible only with portable Bluetooth speakers.
Let me forewarn you though that you should not expect the same performance from a set of Bluetooth speakers as you would from a regular 2.1 speaker system. These speakers are underpowered and lightweight. Their motto is portability, not large sound. Although some speakers, especially those by Bose and Altec Lansing deliver crystal clear and lucid sound, you can't expect to go too high in terms of volume. If you are expecting these speakers to play music for a party of 20 people outdoors, you may have to look for alternative arrangements.
In terms of price, portable speakers are slightly more expensive than standard speakers. Typically, the work through USB or single pin adapters. Major brands are Logitech, Altec Lansing, Creative, and Bose. Many speakers are designed specifically to work with an iPod and have special docks to play from the iPod directly, without any cables. If you are a heavy iPod user, you should look to buy one of these.

You can also buy desktop speakers which sacrifice portability for better, bigger sound. These are like any regular speakers, except that they work through USB.
Portable Bluetooth speakers are great for bringing your music with you, wherever you go. They make music a 'shared' experience. If you are a music aficionado, these should be pretty high on your purchase list.

An Android TV box is just like a smart phone. With a television running the Android operating system, it is easy to load and uninstall software, programs, games and other services. Quite frankly, Android TV boxes present a new generation of set-top boxes which is unlike traditional television sets. Android TV offers users with a wide range of smart TV solutions. It's simple. You get more entertainment and more education solutions than with a traditional TV.
A look at the benefits you get
While you might enjoy playing Android games on your cell phone, ever thought of playing them on the television? The set-top box is equipped with an infrared sensor bar. It is convenient to play classic games also on the Android TV.
There are features galore!
The Android TV supports flash, high definition 1080p video playback, web browsing and more than 500,000 apps and games from the Android market. The variety of functions an Android TV box performs won't let you stay away from it for long. The remote supplied along with the device is great, and 1080p video is played pretty smoothly.
Getting back to the basics
The device is a great investment for people who love to entertain themselves. The technology presented through these devices make the video watching experience totally different. Your favourite videos and movies can be directly watched from your local storage or streamed from internet sources such as YouTube, and more.
Share your favourite websites and news directly from your living room with your family and friends. An Android TV delivers everything an Android device can do, but on a big television screen. Be it browsing the internet or playing games, there is a lot you can do. What you need to run an Android TV box is only a HDMI compatible TV and an internet connection. Then, the whole web world can be at your fingertips from the comfort of your couch.

Have the convenience of using internet right from the TV
The widespread use of the internet as a media source means everything can be watched online, from movies to even niche market shows. This makes the cable television obsolete. It seems now that the future entertainment televisions will have broadband connections serving the content from around the world. The box will render old cable TV networks obsolete in the years to come.
How do you set it up?
The box is simple to set up. The device needs to be plugged into a power source and connected to a compatible TV with an HDMI port so that it is ready to boot up. These devices generally run on Android. One of the biggest advantages of an Android powered TV box are the varied capabilities of the device. Pictures, movies and videos can be easily moved from a PC to the device via Bluetooth or USB. Although the box is not as powerful as a tablet or a high end smart phone, they are fully capable of running the majority of apps available in the app market.

Troubleshooting HID Lamps

So you're cruising along lighting up the pavement with your (hopefully!) well-focused HID lights and some fault comes along with the lights that totally put a damper on your evening. There are many things that can go wrong with an HID system, from not lighting up at all to flickering to fuses blowing out. Not all HID conversion systems are built to the same standards as OEM lights, and as with most things, you get what you pay for. Sometimes, even with the best equipment, sloppy installation practices and/or extreme environmental conditions combine to ruin that nice HID glow.
Many car enthusiasts who would have no problem replacing injectors or installing a turbo simply tear out their hair when asked to diagnose electrical faults. The wires go through unseeable nooks and crannies or some components work well at startup but fail after 15 minutes of running. There are many possible causes of failure in an electrical system. They can be from heat, moisture, corrosion or vibration. Luckily, wire insulation does not degrade for a long time so that is one thing we don't have to worry about - unless you're restoring a decades-old car and you haven't replaced the wiring harness. What this all means is that when electrical failures occur, you just need to check the connections or the components themselves, and not the wires on the harness.
When an HID lighting system becomes inoperative, a simple check of the power switches, the connectors and splices or a visual check of the lamp itself is enough to diagnose the cause of the problem. Through environmental factors or plain poor workmanship, connections and splices may have gotten loose or corroded, which would result in intermittent faults or failure to operate. Bulbs at the end of their life are characterized by low light output and/or intermittent starting. Visual checks may show discoloration at the ends of the arc tube or deterioration of the electrode tip. As a quick check, you may try swapping the headlight bulbs if one side is acting up. If it lights up, then you know that it was the bulb that was at fault. If it doesn't, however, then the HID componentry is suspect. Check the ballast for signs of overheating such as bulging or discoloration. If everything still seems normal, then checking for line voltage and resistance is in order. This procedure may require a visit to your installer or electrician if you don't know your way around a multimeter.

The message here is if you install HID lighting, ensure that the installation is correct from the start. Check for proper routing so the wires don't chafe and insist of soldered splices. Then weatherproof the splices so that water splashes, oils and detergents don't prematurely degrade the connections. With these simple procedures, you can be assured of a more reliable experience for your upgrade.

How To Possess The Functional Projector HID Kits For Upgrading Headlights

Projector head lamps are considered as the most economical way to upgrade any aftermarket headlights. HID Xenon or projector lights are known for rendering maximum performance, functionality and lighting output. Compared to typical HID bulbs, special designed projector HID Kits ensure proper fitment and insertion to bulb slots made for the headlight. All lighting accessories and items inside the kits can be used seamlessly with any aftermarket projector headlights. If you are looking for a functional as well as performance-oriented kit, then you need to go through some smart ways so that you can have better and improved lighting solutions of your choice. These include:

First, you must know your own specific lighting needs before you use your computer and place an online order. It will be ideally good for you if you can check the type, size, design, and color of the HID lights that match vehicle's outer appearance and can make you feel comfortable. When it comes to increasing night visibility, you can make a selection from 3000K, 4300K, 6000K, 8000K and 12000K.

Then, an online research can make a real difference and help you find the best online store dealing in the selling and supplying of quality centered lighting supplies. Once you get a list of online stores using online search engines, you can choose two or three of them to come to a unanimous decision. To have the best HID kits, you must go for features, dimensions and specifications of HID lights that match your needs. Also give attention on the color temperature and lighting output of the bulbs.

Next, you must focus on the kit's quality and it can be done by evaluating quality factors including ISO certification, item no., manufacturing details, signs and symbols. Don't forget to check the kit's factory guarantee or warranty. Moreover, checking customer reviews, testimonials and public opinion can do things differently. When you choose a kit, check its corrosion and water-resistance ability.

At last, the factor that always matters the most and affects your decision directly is the price. It decides the buyers' ability to purchase products on a given price. Interestingly, all lighting kits don't come at the same price tag, but price comparison can help you find the best one with the least efforts. Even, it will help you know whether the price you are 

A Comparison on the Best Bluetooth Headsets for Listening to Music on the iPad

Initially our intention was to compare every kind of Bluetooth headset and headphones available. As we were using the headphones in our day-to-day lives, we realized that certain headsets were better designed for particular functions. Optimizing a product design for one usage often involved degrading important characteristics of another function. This is analogous to building a car. If you want something fast that can go from 0-60 is 4 seconds flat; it's probably not going to get the best gas mileage, or be of much use hauling 3 kids around town. The bottom line is those who want the best headphones for listening to music, or watching videos, have a different product profile than mobile warriors looking to make VOIP calls (more on this topic at the end).
In this product comparison, we are looking for the best Bluetooth headphones to listen to music and watch movies on your iPad. While we emphasized sound quality for music and video playback, virtually all the Bluetooth headsets have built in microphones and VOIP capability. Next week we will have a product comparison for Bluetooth headsets designed primarily for voice conversations that are iPad compatible, and play stereo sound.
The criteria for our product recommendations are sound quality, fit/comfort, battery life, features, and build quality. The greatest weight is our scoring was given to sound quality (approx 40% of the weighting); with the other 4 categories given weights equally divided with the remaining allocation. All the Bluetooth headsets recommended were tested with both the iPad 1 and iPad 2 running iOS versions as early as 4.2. Going back to our car analogy, you cannot expect an inexpensive car like a Ford Focus to compare with the performance of a high end car like a Ferrari. With that in mind, we also broke our recommendations into the best iPad Bluetooth headphones within a given price range.
One last tip before we begin is there no such thing as a Bluetooth headset designed for just the iPad. So if you are browsing online, or walking through the aisles of Best Buy looking for products with the words "iPad Bluetooth Headsets" scrawled on the packaging, you will be severely limiting your selection. When shopping for a Bluetooth headset or headphones for your iPad, just look make sure it's a stereo headset or A2DP capable. The Bluetooth headset you buy for your iPad should work with your cell phone and Bluetooth enabled computer as well.
Best Bluetooth Headsets for your iPad under $40: Arctic Sound P311
Arctic Sound P311 (MSRP $39.99)
Overview:
Our winner for the best Bluetooth headset under $40 is the Arctic Sound P311. If you are a techie the name will sound familiar as Arctic Sound is a division of Arctic Cooling, a Swiss owned company that makes CPU cooling and computer accessories. While the MSRP of the P311 is $39.95, you will find this headset online for around $30. It does everything you want out of a headset at a fair price. We loved this headset over more expensive Motorola and Sony models. Sound quality was indistinguishable from the Motorola and Sony models but the features that won us over were the amazing battery life and the folding design. In addition to testing it with the iPad, we were able to pair this headset with a PlayStation 3, laptops (MAC & PC), Android Phone, iPhone, and Nokia Phone with no problems.
Sound Quality
We paired the Arctic Sound P311 with an Android phone, iPhone, and Nokia to test sound quality when making phone calls. Our friends on the other end could hear us just fine. Sound quality was crisp and there was no lag or choppiness in the conversation. For VOIP and cellular pairing, the P311 includes a hidden integrated microphone, built-in sound processor, and Advanced Clear Voice Capture (CVC) technology. The latter is just a fancy way of saying noise cancelling technology. While the microphone picks up on your voice during calls exquisitely, the noise cancelling function is not on par with higher end headsets such as the newest model Jawbone or Plantronic headsets. If you plan on speaking with a person in a noisy place such as Starbucks during the morning rush, the background noise will bleed into the conversation more than the high end headsets.
For music and video playback the sound was excellent for a device of this class. The music was crisp and vibrant at higher range. The built in high fidelity drivers were able to process sound in low range without any cracks or squeaks. The bass does sound flat when compared to higher end headsets and surround sound speakers. These are not the headsets to do sound editing on your MacBook Pro, but if you are watching Netflix on your iPad or listening to your iPod app, sound quality is excellent.
Fit/Comfort
Weighing just 2.5 ounces, the P311 is very light. The closed acoustic ear cups provides good comfort as we could where them all day without a fatigue or irritation. Some of our readers might not like the behind the ear design but we found this ideal if you are planning to use these headsets at work, as they will not mess up the hair like over-the-head headsets.
Features
One of the most useful features is the right earphone has 5 buttons that control certain settings. They allow you to answer a call, adjust the volume and forward/reverse the music. The device you pair the headset with must allow these functions but we found most do. If paired with a cell phone and there is an incoming call, the Inter-Call-Manager will play a ringtone into the headset. The music will then be paused and will resume after ending the call. Pairing to my iPad was not a problem and the controls worked for volume, skip, reverse, and pause. The Antic Sound P311 does not support multipoint Bluetooth.

Battery Life
The Arctic Sound P311 has a built in rechargeable 400mAH lithium polymer battery similar to the lithium polymer technology Apples uses for the iPad and MacBooks. The manufacturer claims up to 20 hours of listening/talk time for the Arctic Silver but you can only achieve that time under very unrealistic circumstances. When talking on the headset for over an hour and spending the rest of the time listening to music at mid volume, we averaged 12-14 hours per charge. While not the 20 hours claimed by the manufacture, this was enough for a full day's work and double the battery life of other headsets. Mobile warriors will love that the Arctic Sound P311 headset charges via mini USB instead of a proprietary design. If have a Blackberry, you can use that AC Adapter or USB cable to charge the headset leaving one less item to lug around. Charging time starting from a dead battery is about 4 hours. A USB cable is provided for you to plug into your computer or iPad AC adapter.
Build Quality:
The Arctic Sound P311 comes with a nylon hard case so they easily tuck away safely in your briefcase, purse, or backpack. The headphones themselves are made from hardened plastic. Because of its folding design, it can be damaged if you too much force is applied against the hinges. By no means does it make the headsets fragile as the headset was dropped accidentally a few times without any damage.
Bluetooth Compatibility: Bluetooth v2.1 + EDR, A2DP, AVRCP, HSP, HFP 1.5

Best Bluetooth Headsets for your iPad under $100: Plantronics Backbeat 903+
Plantronics Backbeat 903+ (MSRP $99.99)
Overview:
The Plantronics Backbeat 903+ is the upgrade for Plantronics best selling 903/906 series. The Backbeat 903+ was released last year incorporating the newer Bluetooth standards. The most important feature this headset has over the Arctic Sound P311 is the multipoint Bluetooth technology. What multipoint allows you to do is pair two Bluetooth devices with one headset. As long as your devices support multipoint, you can pair your cell phone to the Backbeat 903+ while streaming audio from your iPad. Most new phones support multipoint including the Android and Blackberry platforms. Both the iPhone and iPad support multipoint as long as you are running iOS version 4.1 and above.
Why is multipoint so important? If you have multipoint, you will not miss a call if you are listening to music on your iPad or iPod! If your iPhone rings while your blasting away Metallica on your iPad, the Backbeat 903+ supporting multipoint will pause the music, and notify you of an incoming call. The one touch features on the Backbeat 903+ will allow you to answer the phone without having to physically answer it.
We recommend not paying MSRP by searching online for the best deal. We bought our Backbeat 903+ on Amazon for $69.99.
Sound Quality
In terms of sound quality when making phone calls, the Plantronics Backbeat 903+ is superior to the Arctic Sound P311. This is the result of the superior noise cancelling feature and windshield. The headset has two microphones instead of just one. Both microphones are positioned be shielded from direct wind. Plantronics calls their noise cancelling technology AudioIQ2. Basically what happens is they microphones pick of your voice and digitally erase the background noise to provide a superior phone conversation.
The Backbeat 903+ has a rich and vibrant sound, and can stream music, video, and app sounds from your iPad. The headset has an enhanced bass that provides a deeper, and more earth moving feeling than the P311. While the Backbeat 903+ does have noise cancelling technology, it should be noted that it is for voice calls and not streaming music.
Fit/Comfort
Like the Arctic Sound headset, the Plantronics 903+ is a behind the ear design with close fitting earpieces. Each earpiece adjusts three ways for a custom fit.
Features
The Backbeat 903+ has a unique technology called OpenMic that allows you to hear what's going on around you with a touch of a button. The Backbeat also supports one touch controls allowing you to start/end calls, and control music functions such as volume and pause/play. Voice alerts tell you if there is a low battery, when there is an incoming call, and when you have lost a phone connection. You can also monitor the battery level of the headset on your iPhone with built-in software. And as discussed earlier, the Backbeat 903+ supports multipoint allowing you to connect to your cell phone and iPad simultaneously.
Battery Life
Battery life provides 7 hours talk time. Standby time is 7 Hours. Charge time is 3 hours and the charging interface is micro USB. An AC Adapter is provided.
Build Quality
The Backbeat is constructed of high impact plastic designed for more abuse than a typical headset. If you are runner or plan to use the Backbeat in the gym, you will love its sturdiness and flexibility. The headphones can folded up and a soft protective bag is provided.

Guitar Effects Pedal

Lots of guitarists are obsessed with stomp boxes which are another name for guitar effects pedals. You will tend to find that many guitar players have a least five or six pedals in their collection. A pedal board (a board usually made out of wood which houses a certain amount of pedals) is useful to keep your stomp boxes in order. They can be used in the practice room or on stage. A useful gadget that some musicians own is a zip up pedal mount which makes transporting and keeping your guitar effects pedals together much easier.
The focus of this article is analog effects but other kinds of effects are available including digital effects processors which are generally representations of analog effects. Guitar modeling as become much more popular in recent years and the technology itself as become much better in terms of sound quality and picking dynamics and response. Nowadays you might find that some amplifiers are built around amp modeling software and hardware whilst others have effects units built into them. The circuits in analog guitar effects pedals can be integrated into valve amplifiers and can, therefore, act as an extra overdrive channel. It is not uncommon for reverb (short for reverberation) to the built into amplifiers. Spring reverb can sound very natural whilst digital reverb in generally of lower quality. The discerning musician usually has a good ear for music and will be able to tell the difference whilst a newbie guitar player might not mind the lower quality alternative. Some stomp boxes have great reverb which can sound like the real thing. This can be extremely useful if your guitar amplifier did not come with spring reverb built in or as a particularly low quality sounding reverb or the wrong variety of reverb for the sound that you are trying to achieve.

The most popular types of guitar effects pedals are overdrive, distortion and delay. But the types of effects that are available are many including compressors, phasers, flanger, chorus and even an acoustic simulators.
Compressors can be used to even up your sound and add sustain.
Phasers and flangers are similar sounding modulation effects pedals. The flanger has a more pronounced sweep.
A chorus pedal can be used to add a full sound to your mix and is heard in many professional recordings.
An acoustic simulator can make your electric guitar represent similar tonal qualities to an acoustic guitar.
