Just tried and no matter how many times I tap, tap and hold, rub them, ask them nicely 🙂 they don’t come back on. I really would like to have this option as sometimes you don’t have your case with you, get interrupted (for me on a long walk or run), my bluetooth player turns itself off after 5-10 mins if it’s not playing which means the buds will turn off and I’ve not way of turning them back on!
