GVAudio Digital to Analog Audio Converter

Looking to enhance your audio experience? I'm selling a GVAudio Digital to Analog Audio Converter with Bluetooth 5.0 Receiver. It's perfect for adjusting the output volume of 3.5mm+RCA(R/L) Jack audio. You can also support phone call function with it. It's a bluetooth receiver, not a bluetooth transmitter. It also features a two-stage gain switch that enhances the signal input into the amp circuit
