What is Bluetooth?
Bluetooth is a wireless communication service. You can use Bluetooth to send pictures, songs, videos, and other stuff over to other phones. You can also send files and licks over using Bluetooth.
You can also use Bluetooth to connect hands-free devises and use these devises to talk to friends and family on the phone without pressing a button on your phone.
This transfer of audio information from mobile phone to headset is done through the use of Advanced Audio Distribution (A2DP), which enables the audio to be streamed from a mobile phone through to a headset, enabling users to talk while on the move.
