There is a MINISO in our mall now so we went and it is filled with blind box toys and hello kitty cosmetics and WHATS THIS a $30 pair of "Smart Eyewear" that I immediately purchased. They have Bluetooth speakers built into the frames. I just used them to make a call, not terrible. A bit heavy. Magnetic charger.
Here it is charging. Both arms of the glasses charge, and each has a very cheap looking metal button for interacting with the tethered Bluetooth device.
@mauve just audio.
