A Sony Bluetooth High Fidelity
A2DP/AVRCP Stereo Headset

As the more and more Symbian phones come with the A2DP/AVRCP support these days, it is only natural that the wireless BT headset becomes more and more popular all over the world as well.

For those who don’t know, Advanced Audio Distribution Profile, or A2DP for short, is just one of the many standardized applications of Bluetooth.

Advanced Audio Distribution Profile is the technology that lets devices stream high-quality sound in stereo to each other via Bluetooth™. Also some of them have a hands-free feature that makes such headphones as the perfect solution for Smartphones users.

Without sounding too technical, A2DP basically allows stereo sound to be transferred to a headset or even car stereo, wirelessly. Basically all you have to do is to pair an A2DP headset with an A2DP Smartphone, and you can enjoy in your favorite tracks while the you're phone's in the pocket, or across the room.

For the 2007 Consumer Electronics Show (CES) 2007.

Sony has announced 5 new Bluetooth accessories for audio devices, 2 of which are designed to pair with a Bluetooth enabled mobile phones so users can listen to music and answer calls all in one device.

So if you get bored of your standard headphones that comes in the phones package, Sony is coming to the rescue you with two sets of stereo Bluetooth headphones targeted at audiophiles, two high fidelity headsets, DR-BT21G and the DR-BT50.
