The receiver needs to be powered by usb and from it an aux cable to the mixer. The transmitter looks pretty okay and has a gain knob in the battery area. Sound is bad it has a weird humm but that can be my setup. Overall I really don’t like the receiver… probably is good only for comouter applications that can take that as usb

Works great for my application. I use the auxiliary out to the auxiliary in on my amp and plug the USB end to a USB charger. I am no more than 15 feet from it so I don't have any problems with signal drop out.

It’s a win win! We needed a new lapel microphone and I saw this on the website and thought I would try it. I’m happy I did. The convenience and performance are awesome. I’m considering buying another set

This electronic gadget provided me and my family to better communicate with my nephew while at his physical therapy hospital so that we can hear his voice amplified.

This has exceeded my expectations. I use it for Zoom calls. I bought it several years ago, actually and have yet to change batteries. Love it!
