The BSH 338 is a bundle package incorporating a Bluetooth stereo clip headset and a Bluetooth USB dongle based on Bluetooth 1.2 specification and support for the new Advanced Audio Distribution Profile (A2DP).
This combination allows users to connect wirelessly to a desktop or laptop audio source and receive true stereo sound through the headset.
The BSH 338 supports a second audio device, incorporating the headset profile needed to connect it to a mobile phone. This combination allows users to receive calls even while the headset is being used to listen to music. At a touch of the multifunction control key the device will mute the sound and connect to the paired mobile phone. At the end of the call the origina sound connection will resume automatically.
The headset also allows dial or redial the last number called via voice command, if supported by the phone.
