Review on 🎤 JOYO 5.8GHz Wireless XLR Microphone System - 4 Channel Dynamic Microphone Transmitter and Receiver for Audio Mixer, PA System, DSLR Camera (MW-1) by Alan Pfeiffer

I tested them by plugging the transmitter into my mixer, mixing XLR and plugging the receiver into my powered speaker. The sound was good and I only tried them for 1 hour and 15 minutes. . (I'll see how long they last on battery next time.) Also left the charging cable plugged in and they worked. So far, so good. I also used them with a microphone and yes everything worked fine.
