I am using this BT audio board as battery powered compact stereo speakers for my study. The board couldn't be easier to use. After turning it on, it immediately showed up as an audio device for my smartphone and everything worked as expected. Powered by 3S Lipo with 2.2" 10-Watt drivers, it's very loud (much louder than your regular low-cost BT speaker). The remote control is handy, and a dedicated equalizer button is a quick and easy way to control the Optimize sound quality for the specific drivers you are using.
