Review on 🔊 Air Audio - World's First Pull-Apart Portable Bluetooth Speaker, White - Enhance your Surround Sound Experience and Enjoy Multi-Room Use by Kristine Black

One of the speakers seems to be buzzing with loud amplification. Probably a bad solder joint. Your next version should identify: Left front Left back Right front Right back Centered with a subwoofer (maybe he already has one but I can't tell.) Add volume controls for each satellite or app to control them: Volume, Tone, Delay, etc. D. Also give the option to increase the power output (louder) when plugged in (USB-C can use 12V instead of 5V). I've been thinking about this idea for about 3 years. Thanks for that, now make it perfect.
