Bose has unveiled its new Bluetooth headset. The Series 2 headset features the same form factor as the original, but now comes in left- and right-ear versions. A2DP streaming has also been added, alongside Bose's Adaptive Audio Adjustment technology that automatically adjusts the speaker volume in response to changes in ambient noise levels - keeping the volume down when in a quiet office and pumping up the volume when you step out in to a busy street, for example.

Other improvements include a new internal antenna to improve reception with a mobile phone stowed away in a pocket, and dual microphones that work in conjunction with Bose's proprietary signal processing technology to filter out background noise and reduce wind noise. Answering a phone call is done with a simple top-to-bottom pinching motion on the unit's buttons, with labeled LED indicators displaying the battery life and Bluetooth connection status.
