Review on Moukey Mini Amplifier Home Audio Bluetooth 5.0: 50W 2 Channel Power Audio Receiver FM USB AUX – Remote Control & Power Supply for Car, Home, Tablets, Phones, Computers – MAMP2 by Brooke Stolen

Unfortunately I have to give this product a bad rating. I heard a piercing howl through the speakers as I connected to my phone via Bluetooth. I contacted the company and ran all the diagnostic steps they recommended, including removing the phone from the unit as far as possible and leaving the Bluetooth connection intact - I even used a different set of speakers so I know it wasn't t MY equipment. It didn't happen in FM radio mode or when physically connected, but I bought it specifically to be able to take the phone with me in space and connect via Bluetooth, so it was a deal breaker for me. I even had a second block sent to me, hoping that would solve the problem. the second did the same. I ended up returning BOTH devices for a refund and I HATE that! So I have to let you know what bluetooth is for. You can choose another product. If you're hardwiring your audio source or just want FM radio, this might suit you better.
