" Resound Micro Mic and ReSound Multi Mic
Part of the Smart Hearing experience
The ReSound Micro Mic and ReSound Multi Mic are part of an interconnected wireless hearing solution from ReSound. They connect directly to ReSound wireless hearing aids and extend the hearing range by more than 80 feet in clear line of sight."
In early January, I went to an Indian restaurant buffet with wife and a daughter. I left my Multi-Mic at our table and went to the buffet counters. I could clearly hear what they were saying from at least 50 to 60 feet away (I forgot to bring my tape measure!). I haven’t mastered the Multi-Mic. In omnidirectional mode, it does seem to be a bit sensitive to noise from a distance and unlike the Phone Clip+, it doesn’t stream through existing programs. It has its own individual program once it’s paired with your HA’s. But you do have access to tuning bass, midtones, and treble +/- 6 dB in each direction. You can control the amount of noise or wind noise reduction you apply, pick streaming only from the Multi-Mic to your HA’s (HA mics off) or control the relative volume of streaming and your HA mics that’s played to your HA receivers. Used unidirectionally (hung vertically from someone’s neck), it’s a lot better at not picking up outside noise.
