Seat-belt microphone (mobile phone preparation)

Audi is the world’s first sports car manufacturer to integrate the microphone for the optional hands-free system into the driver and passenger seat belts. This new position shortens the speaking distance from the microphone and improves voice quality.

The seat-belt microphone is included with the optional mobile phone preparation and optional Bluetooth interface on the Audi R8 Spyder 5.2 FSI quattro. A total of three microphones are integrated into both the driver and passenger seat belts. The seat-belt microphones are positioned so as keep the speaking distance constant at between 10 and 15 cm, thereby enhancing intelligibility for the person on the other end of the line.
