Phonak PartnerMic is a discreet microphone designed to improve hearing during one-to-one conversations. Attach the microphone to your conversation partner's clothing and it will transmit the persons conversation directly to your hearing aids using innovative AirStream™ technology. The microphone is always directional enabling it to assist with one-to-one conversations all day. The PartnerMic can be either clipped onto your conversation partner's clothing or on the lanyard.

If your partner then goes out of range, the audio will automatically reconnect when they return. The product can be fully charged within 2 hours and has a battery use time of up to 6 hours. The product is compatible with Phonak Marvel or Paradise hearing aids and includes 1 year warranty. Dimensions: 55 mm length, 29mm width, 15mm depth (including clip).
