Bluetooth Stereo

Bluetooth stereo headphones and Bluetooth stereo headsets allow you to wirelessly listen to digital-quality music with your computer, MP3 player, home stereo, cellular phone, or any other device that supports Bluetooth stereo audio.

Bluetooth stereo audio is one of the fastest growing Bluetooth applications and the second largest overall application in the Bluetooth arsenal, just behind hands free communication for cellular phones. As a result, Bluetooth stereo headphones and Bluetooth stereo headsets have become extremely popular among manufacturers and users alike

Benefits of Bluetooth Stereo:

Wireless Streaming of Digital Audio

Bluetooth devices using the A2DP Bluetooth Profile (Advanced Audio Distribution Profile) offer stereo quality audio which can be streamed wirelessly from a media source to the headset / headphones.Â

Convenience

The convenience of wireless Bluetooth stereo audio is incredible. You can walk around your home with your Bluetooth stereo headphones and not have to worry about carrying your iPod or MP3 player around with you. You also won’t have an annoying wire dangling around your neck. You can stream music from your laptop, PC, TV, DVD player, home stereo, or MP3 player.

You will also find them very useful while exercising or for any other activity which requires increased motion. We have all seen people who have iPods strapped to their arms with a pair of wired headphones dangling in their faces. Looks rather annoying, doesn’t it? Next time you are at the gym, take a look around and see how many people actually spend more time messing with their headphones than they do working out. With Bluetooth stereo headphones or a Bluetooth stereo headset, just keep your iPod / MP3 player within range of where you are and you can continue to comfortably workout. Most Bluetooth stereo headphones and Bluetooth stereo headsets offer a range of up to 30 ft. Some of the newer models, using the latest Bluetooth technology, have an extended range of over 60 ft.

CD Sound Quality

When most people think of wireless audio, they usually think sound quality will be compromised. Surprisingly, sound quality is exceptional with most Bluetooth stereo headphones / headsets. It is very comparable to high-fidelity, digital CD quality. In most cases, the sound quality is as good as if it were coming from a pair of wired headphones.

Bluetooth Dongle

Definition

A Bluetooth Dongle adapter is a Bluetooth adapter that connects to your computer via USB port. Bluetooth Dongle is different from other Bluetooth adapters that can be installed inside your computer, and as such, enjoys much greater popularity than other, more expensive and less user-friendly Bluetooth adapters.

Installation

Installing your Bluetooth dongle adapter is very easy. Simply plug the adapter into an unused USB port–where you won’t mind it staying–and then insert the Installation CD that came bundled with the dongle adapter to download all drivers and software necessary for the Bluetooth devices to run correctly. Once everything has been installed, simply restart your computer and your Bluetooth dongle adapter will be fully installed and operational.

Using your Adapter

To get the most out of your Bluetooth dongle adapter you will need to sync it with Bluetooth peripherals. As mentioned previously, this could be anything from keyboards to headsets and even video game controllers. To sync your devices with the Bluetooth adapter, simply put the Bluetooth dongle adapter in sync mode via the desktop software you installed previously (see your owner’s manual for more on this) and then put the peripheral in sync mode as well. Once these devices “find each other” they will be able to work together in your Bluetooth personal area network. These devices can each be managed individually using your Bluetooth software, so if you need to make changes or set preferences, you can do that by starting up the software from the start menu.

Troubleshooting

Bluetooth dongle adapters are very user-friendly, but that doesn’t mean that some have not experienced problems with them. One very common problem is the USB port specifications. If you have an older computer (manufactured before 2006) you will need to find out if your computer has USB 2.0 ports and where. Since Bluetooth is a high-speed networking tool, it needs the faster 2.0 speed in order to function correctly. Another common issue consumers have with Bluetooth dongle adapters is getting them to sync correctly with peripherals. Syncing your peripherals is more art than science, and you’ll have to engage the sync mode on both the adapter and the peripheral at exactly the right time in order for them to discover one another and form a network linkÂ

Bluetooth Headphone

Bluetooth headphone is a wireless technology that allows devices to communicate via high-frequency radio signals. The installed base of Bluetooth devices was over 500 million products at the end of 2005 and is projected to surpass one billion by the end of 2006, making it the only proven choice for developers, product manufacturers, and consumers worldwide.

Â
Bluetooth headphone is just one of the many devices designed to work with portable music devices as well as ordinary phones. With Bluetooth headphone, you can listen to music as well as make and receive calls–all from the same device. Connecting them is a snap.

One of the newest applications of Bluetooth technology is the ability to wirelessly stream music from a mobile phone to a stereo headset. Bluetooth headphone enables consumers to listen to music wirelessly from their audio device without compromising sound quality. Consumers can enjoy longer battery life and listen to music at a distance without the hassle of cumbersome cords.Â

There are several Bluetooth headset on the market today that enable users to wirelessly listen to stereo music from their A2DP enabled device (such as an MP3 player, PC or PDA). Many of these models also enable users to make and receive calls to take their Bluetooth mobile phone. When an incoming call, the music paused and the user simply presses a button on the headset to answer the call. With Bluetooth headphone, such as the Motorola Bluetooth Stereo headphones, users can also wirelessly switch between a variety of sources, such as a stereo, computer or MP3 player with accompanying Bluetooth stereo accessories.

Bluetooth Wireless

Bluetooth wireless technology is wireless connection within short distances that enables electronic devices to be connected for the transfer and sharing of data as well as voice signals. Bluetooth technology is powerful and relatively inexpensive, which means that it has become very popular among computer-savvy people. Learn the fundamentals of what Bluetooth wireless technology is, and explore how you can utilize this useful method of connecting wirelessly.

Bluetooth was released in 1998 with the planned purpose of replacing wired technology in data and voice transfers. The people who developed Bluetooth technology initially named it “Bluetooth” as a secret code, but the name held over time. Bluetooth inventors want to establish a universal language recognized by all electronic devices.

Bluetooth Wireless technology operates on a frequency that is the same as cordless telephones, WiFi and other wireless electronic devices. Devices enabled with Bluetooth capabilities must be configured to understand specific Bluetooth profiles of other devices in order to connect to each other.

Bluetooth has become a wireless standard. More devices will be modified to use this technology, and manufacturers will be looking for new ways to make their products Bluetooth compatible

The market for Bluetooth input devices will continue to expand. Innovative new use cases are under development, such as a two-way remote control where consumers can view the TV on the remote device and the television screen. These types of use cases will expand scenarios for Bluetooth input devices into the digital home environment and other areas that require more power. Â

The SIG recently launched the Experience Icon Program to guide and help consumers purchase interoperable products implementing Bluetooth wireless technology. Products containing the Input icon contain the Human Interface Device Profile (HID), which allows for complete interoperability among a range of devices. When consumers and retailers see the Input icon (below), they will know at a glance that the device in question wirelessly connects mice, keyboards, game controllers and other input/output devices to computers, PDA’s and game consoles.Â

Bluetooth Adapter

Bluetooth adapter is an economical gadget, manufactured by various manufacturers in the market like, Aliph, BlueAnt, Mogo, Motorola, Plantronics, and Samsung. Any device must be judged on its battery back up, sound quality, comfort during usage, style & ease of use. The following gives you an idea about each feature that one needs to look at while picking a Bluetooth adapter.

Battery Life: Each headset must be tested for one full business day to check how long the batteries last.

Call Quality: Sound quality must be good even with background noise. One must check if the voice is clear even with disturbance in the background. The 2nd item that needs to be checked is the headset volume. Check whether it’s loud enough. The final item that needs to be checked is whether callers both hear and be heard?

Comfort: Check if the Bluetooth adapter fits well in the ear; does the headset stay in place? Are there different-sized ear inserts provided for achieving a more precise fit?

Style: heck if the look turns people. Does it look good? What type of user is a good match?

Ease f Use: Does it pair easily with other devices? Are the controls simple to use for the end users?

Bluetooth adapter works using the plug-and-play feature of the Windows and Mac operating systems. They can be removed and reinserted any time as per the users wish. When you plug a device in, the software driver stored in the device is transferred to and interpreted by the operating system. There is usually no installation required here. However, few adapters do require drivers to be installed from a CD when used for the first time. Bluetooth adapter is a special USB device that allows a non-Bluetooth-enabled computer to sync and interact with Bluetooth devices like keyboards, headsets and printers. Using a Bluetooth adapter is fairly simple, and as long as you have the right hardware and software. The main advantage of this technology is that in no time, one will be able create his/her own personal Bluetooth network

Bluetooth Driver

Bluetooth driver also known as profile driver is written by independent hardware vendors (in short, IHVs) to support various protocols defined in the Bluetooth specifications. Profile drivers should follow the Windows Driver Model (WDM) architectureÂ

To support the Bluetooth protocol, Microsoft supplies several Bluetooth drivers and support files, including:

BthPort.sys

BthEnum.sys

BthUsb.sys

BthProps.cpl

IHVs must use Windows Vista or later to develop their profile drivers because earlier versions of Windows, including Windows XP with SP2, do not support profile driver development.

The Bluetooth driver stack provides device driver interfaces (DDIs) that enable profile drivers to access Synchronous Connection-Oriented (SCO) links and Logical Link Controller and Adaptation Protocol (L2CAP) links between the local system and remote Bluetooth devices

SCO

Synchronous connection-oriented (SCO) links are point-to-point connections between two Bluetooth devices. They are defined primarily to support time-bounded information like voice.

L2CAP and SDP

The L2CAP is designed to support asynchronous connectionless link (ACL) Bluetooth links. The Bluetooth driver stack provides support for connection-oriented services. Profile drivers use the Bluetooth L2CAP DDIs to open, update, and close L2CAP connections, as well as to perform read and write operations over an open L2CAP connection. Â

There are two installation types for Bluetooth driver:

Client-side installation

Server-side installation

Bluetooth USB Adapter

Bluetooth USB adapter, sometimes called Bluetooth dongle, is a small, economical gadget that enables this technology on home computers, providing many potential benefits. One has to just plug in the adapter to a USB port and the adapter completes the remaining. Bluetooth USB adapter works in Windows & Mac operation systems using plug-and-play feature & hence can be removed and reinserted at any time. When you plug a device in, the software driver stored in the device is transferred to and interpreted by the operating system. There is usually no installation required, although some adapters do require you to install drivers from a CD the first time you use them. Â
Â
Once it’s installed, the Bluetooth USB adapter usually lights up and begins sending signals to search for Bluetooth devices in the area. If it finds any, you are given the option to communicate with themÂ

Benefits:

Wireless printing, communication with cell phones and PDAs, file transfers, network sharing, and using a wireless keyboard and mouse are among the many things you can do with Bluetooth USB adapter. Bluetooth is cheap to implement, supports a high rate of data transfer and is very secure. Because Bluetooth uses “spread-spectrum frequency hopping” there is little worry of interference even when many devices are communicating at once.Â

Short Comings:

The only downside to Bluetooth USB adapter is its limited range, although more expensive adapters can communicate effectively over 300 feet. Â

The Kensington Bluetooth USB 2.0 adapter gives you enhanced speed, security and reliability for your favorite Bluetooth devices.Â
