How Does a Bluetooth Headset Work:

The Personal Area Network:

• The cornerstone of Bluetooth technology is the Personal Area Network, or PAN, which creates a short range network that is accessible by all devices using the Bluetooth protocol. This is why Bluetooth headsets can be used with computers, cell phones, or even a PlayStation 3. However, before this network can be formed, connections must be formed

Headset Connection:

• In order to get your headset to work with specific devices, you have to create an initial connection. This process is known as "syncing" When you sync your headset with a device capable of receiving Bluetooth information, then you are creating an invisible link between the two devices. This link can be a part of a larger PAN that includes other devices, or as is often the case with Bluetooth headsets designed for cell phone use, the PAN is a simple one way link that sends data from the headset to the phone

Information Sharing:

• A Bluetooth headset transmits information that comes through it to the phone, PC, or console that it is synced with. The information is then transmitted through the receiving device's own Bluetooth-specific transmission method to make sure that the information gets where it needs to go. Although the process sounds complex, information in this sort of network only flows one way, and the Bluetooth signal only facilitates the initial transfer of this data. Specialized protocols and software handle the rest

How to Compare Bluetooth Stereo Headsets:

Standard Features:

• Compare features common to all Bluetooth headsets, whether mono or stereo. What are the standby and talk times? What is the maximum range between device and headset? Does the headset support hands-free applications, such as voice dial

Audio Profile:

• Consider the sources from which you stream audio. The Advanced Audio Distribution Profile (A2DP) allows you to listen to music, make a call or switch between the two. The Audio/Video Remote Control Profile (AVRCP) also lets you control volume, playback and other functions for equipment such as stereo systems and TVs

Design:

• Compare size and fit. Do you prefer small earbuds, large headphones that completely cover your ears or something in between? Are over-the-head or behind-the-neck headphones more comfortable? Are controls within easy reach

Use:

• How will you use your new headset? If you listen to music while jogging or playing sports, fit is very important. In noisy surroundings, you need a headset equipped with noise reduction technology. Try different headsets to see how they feel and, most importantly, how they sound
