FX 7009

SMK has developed a full-duplex system microphone-free Bluetooth headset featuring an earphone unit that functions both as an earphone when listening and as a microphone when talking.

The microphone function has been achieved by inserting the earpiece into the ear, picking up faint vibrations of the eardrum within the external ear canal. The microphone-free structure makes the FX 7009 less susceptible to external noises than most Bluetooth headsets.

In addition, the simultaneous use of echo and noise canceling functions allows uninterrupted conversation, even with background noise that usually inhibits phone call conversations (such as the whistling of strong wind).

The FX 7009 supports Bluetooth 2.0+EDR and achieve approximately five hours of continuous communication time.
