Review on 🔊 HELMER Bluetooth Amplifier in Wall: High-Quality Stereo Audio System, 5 Inches Touch Screen Video Player, White (BM207M)" by Motogp Portillo

available I had an electrician install this unit on my living room wall and also installed the ceiling speakers. I was very dissatisfied after the installation because the sound quality is very poor. I was about to return the device. When we removed the unit from the wall, we thought we accidentally swapped the speaker wires. Then swap the speaker wires. The problem is solved. Now it works great, sounds perfect. I would suggest checking the speaker cables if you find the sound quality is poor. I will order more for my workshop. Recommend!
