SVEN Company presented a new SVEN AP-B770MV wireless headset oriented to operate with any devices and PC, which have the Bluetooth module on their “board”. Soft ear cushions fit tightly an auricle providing high level of noise insulation and comfort when using the headset for up to 22 hours, just this time can be provided by the built-in battery of the headphones. The model can be used as headphones to listen to audio (to start tracks, switch them over and control volume) or as a headset to receive an incoming call, activate the voice-activated dialing function.

Ear cushions of the model are of the closed type, the outer side has an interesting print more closely resembling the shell of a scarab or turtle. As the device supports the Bluetooth mode and there are no cables, it eases the life for those people, who use headphones in the municipal transport every day. On/off and volume control buttons of the model are located on the left cup, pause/play and track switching buttons are on the right one. Movable pivot points located close to ear cushions make it possible to rotate them for ninety degrees. Therefore SVEN AP-B770MV can be easily packed in a suitcase; the headphones do not occupy much place in such a position. And their weight is 200 grams only.
