Review on 🎤 Enhanced Performance Wireless Instrument Microphone: UHF Clip Condenser Mic for Horns, Trumpets, Clarinets, Saxophones, Cello, Computers, Phones, Speakers, Voice Amplifier - 131ft Range, 1/8＆1/4'' Port by Melvin House

This is a great little rechargeable set. it's good for brass and percussion (congas, bongos, and other quieter types that require special love). It's directional, so I've had few issues with feedback on stage. I bought the UHF version, not the 2.4GHz model. .I assume that the WLAN frequency model will be more susceptible to interference. I had no problems with crosstalk. You can use multiple devices and sync one at a time.
