Considering audio connection functionality, Starkey’s 2.4 GHz Remote Microphone + accessory is nice too.
Both Starkey 2.4 GHz Remote Microphone + and ReSound Multi-Mic+ have these features:
- Lanyard mode mic
- Table mode mic
- Analog line-in (ex: 3.5mm TRS) audio input
- EuroPlug audio input (for compatibility of Phonak Roger X receiver)
- T-coil (for compatibility of loop system)
Plus, 2.4 GHz Remote Microphone + can work as A2DP streaming receiver and Handfree profile (telephone) for Bluetooth Classic devices. These are what Multi-Mic+ can’t do.
