Review on XRONG Bluetooth 5.0 Stereo Audio Amplifier Receiver Class D Mini 🎵 Hi-Fi Integrated Amp – 2 Channel, 50W x 2, Black (with Power Supply) by Jeff Keegan

Line connection is not a problem, except that you have to switch from Bluetooth to line connection every time you turn on the device. me. In Bluetooth mode only, there's an awful high-pitched squeak from the right speaker that can't be easily reduced. In fact, the only way to make it quiet enough to be tolerated is to turn the volume up to 100%, which has its own issues with Bluetooth. You just can't hear the full music from an Android phone on volume 1 because the audio code isn't working properly and even volume 2 on my phone makes the music too loud to hear comfortably at full volume. . I haven't heard any Bluetooth at all since day one because it's impossible to recover. There's also a voice (with a heavy Chinese accent) that starts when it's on and can't be turned off. She doesn't know about the volume control. It's always a bit noisy.
