The SmartLink is a hand-held 216-217 MHz FM transmitter with built in directional microphones. As far as its FM transmission ability it's a very similar to (and compatible with) the HandiMic and the Lexis.
But, the SmartLink has some other significant features besides just being an FM transmitter.
- It operates as a remote control for Phonak hearing aids that support that.
- It includes a Bluetooth capability that lets it make Bluetooth compatible phones couple with your hearing aids.
The SmartLink is part of Phonak's MicroLink system.
