Sony has launched a new Bluetooth 2.1 headphone range for cable-free audio. With Sony's echo and noise cancelling tech, "exceptional" sound quality is promised.

There are two new models, the DR-BT100CX and DR-BT101. Both claim to feature simple, easy to use finger-tip controls for volume, play and skip music tracks, and to accept or reject incoming calls.

The DR-BT100CX in-ear headphones get USB charging, three sizes of silicon ear buds and 8 hours of playback time.

For a headband headset the DR-BT101 gets a 30mm neodymium driver and 12 hours of playback.

Both Bluetooth headphone models are said to be available to order now at, although they do not show up on a product code search yet.
