So, oddly after Apple said wireless is the future (but then included wired lightning headphones), I looked at these AirPods for my iPhone. there are no actual controls on the headphones? If I want to change the song or even turn up the volume, I have to say "turn up the volume"??? Using Siri in public is awkward already, let alone saying "Turn it up" at the gym. Of course, I can reach into my pocket and use my iPhone too control but then there is no convenience. Thoughts?
