A friend just got the new Sonos Ace headphones and is really impressed with the sound quality compared to their old Sony’s. The one downside they've noticed is that when they connect the Ace to their iPhone with a USB-C cable, it seems to drain the phone's battery pretty quickly, probably because it's charging the headphones at the same time. They're wondering if there's a way to stop the headphones from charging while connected via USB-C, as they really like the lossless audio quality but don't want to have to buy an extra adapter just to use the headphone jack. Any ideas?
