I agree that it would have been better if there was a way to change the volume via the AirPods directly, but I'll probably just do it from my phone (same for changing the track) - I'm not fully sold on using Siri to control them but the other features were enough to persuade me to give them a tryBut what if you're socially nervous and would rather change the volume discreetly? I usually turn volume way down before walking into a building or public transport, I get super self conscious about other people hearing my music because I absolutely hate it when I can hear someone else's. It's such an obnoxious thing.
