HOLD to turn that earbud ON/OFF

I believe it would beneficial to have a function where if you hold on say one earbud, it will turn it off, (to save battery or whatnot) but it’s still outside of its charging case.

I often take my earbuds out but don’t want to put them back in the case, but want the option to turn the earbuds off or it automatically turn off if it’s not in use and then hold to turn it back on and pairing.
