Just sold my AirPods on Craigslist. They were nice, and I really, really like the charging case. Had some weird BT issues, especially when switching devices, but nothing turning on/off BT couldn't fix.
For me, the reason I sold them was simple - I never listen to anything! It's too distracting while working, I run without music, and on the train I've been reading on my Kindle so I don't need audio. I guess I thought the AirPods would change my daily habits... but apparently not!
Really, really cool gadgets, though.
