I found this on the shelf, but I don't know what it is. According to AI: "AI Summary: +3 This image is a remote control for M's Style's mini Bluetooth 5.0 power amplifier. It supports USB/SD/DVD/CD input. It can be used for home or car audio. It also supports MP3 player functionality. It's a small stereo digital power amplifier. It's an M's Style remote control with multi-function buttons." As you can see in the third photo, the transparent seal is still attached, so I know it's unused. For those who know what it's for! Thank you for looking.
