Rexing AUX2 Mini Bluetooth Receiver for car w/ Bluetooth 5.1

Amazing product, works just as advertised, slightly poorer quality than direct aux connection, but that's to be expected!

the sound came out of the car speakers very weakly, when you turn up the volume so that it was normally audible, some strange hissing. Although when you turn off this device and just turn on the radio in the car where music is playing, the sound is high-quality and without hissing.
