Will PMMN4076 work with my radio?
It is designed for specific Motorola portables. Share your exact radio model (and firmware if available) and we will verify compatibility immediately.
Does windporting really help in the rain and wind?
Yes. Windporting drains water away from the mic port and reduces wind noise so your voice gets through.

Yes. Plug your earpiece into the integrated 3.5 mm jack for discreet monitoring in noisy or guest-facing environments.
