Review on 🎤 UHF Dual Wireless Microphone System - Handheld Dynamic Mic with Rechargeable Receiver, 164ft Range, for Karaoke, Party, Speech, Wedding, Meeting, PA System in Red and Gray by Jason Paredes

i have only used it once so far due to the covid situation. I used them to sing in church. I haven't had any problems with them. You sound great. They are easy to use. Turn on the microphone and receiver and start singing. You can adjust the volume if you want. You can change the frequency if you have interference. I haven't experienced anything like this before, so I can't say how it works.
