I tried a pair of earbuds with the same idea from AliExpress. They had the regular controls, but also worked as e.g. a camera remote. Very cool if it had done anything it was supposed to do consistently, but unfortunately it was not well-implemented. If the AirPods Pro 3 (which I was already strongly considering) have a case with a screen that isn’t much larger than the Pro 2 case, I’ll probably buy that model.
