This XLR Bluetooth receiver works very well. I use it in a church to broadcast music from a mobile phone by connecting the XLR output to a microphone input via an attenuator because the output is line level. Unfortunately, I regret that when the receiver loses its Bluetooth connection and tries to re-pair, it sends deafening beeps on the XLR output. You can imagine the result in the middle of a service. So, I remove one star.
