The pair adapts to every helmet and intercom on the market and the 12-hour battery makes you travel without interruption. The voice assistant, the noise-canceling microphone and the volume adjustment make it easy to use on the road for a pleasant and relaxing drive. The TTS for the voice reading of the incoming call and the redialing of the last call are a touch of class of Interphone Edge.
