Review on In-Wall Wireless Music Receiver by Pyle - Home Theater Receiver with In-Wall Audio Control - Bluetooth & NFC Wireless Receiver, Aux (3.5mm) Input - Compatible with Smartphones, Tablets, Laptops, and Computers (Model: PWPBT47) by Chinelo Aranjo

The product idea is great but the hiss and hum from the speakers when bluetooth is on is real and annoying. I've debugged every part of my system and I can definitely isolate the hum from the bluetooth connection. I've tried multiple Bluetooth devices with the same effect each time. It is a pity that the best components are not used in this device to prevent these interferences. Otherwise the product would be great. Just connect a Bluetooth device and control your entire home system from a room away from the amplifier? Yes, too good to be true with this device. I regretted returning this item a few days later. By the way, all my stereo components are of high quality. All wires are properly sized, shielded and twisted to avoid interference. No power source touches or even comes close to the wires throughout the ride. Everything is properly grounded. There is no feedback or interference in my system until this device's Bluetooth is enabled. Such a shame.
