>Wireless headphones are at a fundamental disadvantage in that they have less battery capacity than a phone.

I’ve been using a pair of beats for over a year now, and have never run out of batteries with them, even on multi-leg long haul flights. I use them constantly, and almost exclusively charge them when I have to go to a meeting, which doesn’t usually happen more than once a day. I used AirPods before then and their battery life was even better.
