Clip this Auracast enabled mic onto the clothing of a conversation partner or place it on a table for extra support when you’re listening from a distance or somewhere with loud acoustics.
The ReSound Multi Mic+ is a superb quality portable device that streams speech and audio directly to your ReSound hearing aids and is compatible with ReSound Nexia, Danalogic Extend and later generation hearing aids.
The ReSound Multi Mic+ offers the same excellent benefits as the ReSound Multi Mic with extra features:
When placed horizontally on a table the ReSound Multi Mic+ automatically switches into an optimized table mode to enable pickup of the voices of multiple speakers.
An additional real-life benefit is that, since the listener is not required to look directly at the speaker(s) during a conversation, he or she is free to perform dual attention tasks that normal hearing people take for granted.
In essence the ReSound Multi Mic+ extends the hearing range well beyond the reach of any hearing instrument on its own in a variety of situations, such as when having conversations:
