I love my Powerbeats2's -- they never fall out and I never get tangled or tugged on by a cord, and they actually sound really nice.
Granted, mine had an issue where after about eight months the front plate of the little controls unit on the cable fell off -- but Apple shipped me a return box overnight and overnighted me the replacement unit, no hassle whatsoever.
The 6 hour battery can be a bit of a pain -- the powering down jingle is possibly the saddest song in the world. But if you get into the habit of charging them at night it's enough to get you through a normal day. And connecting is rarely an issue -- unless you try to connect to another neighbouring device, like your Mac. Total nightmare, as is getting reconnected with your iPhone again afterward. Sounds like the W1 chip solves that, but I'm not about to drop another $200 just to do away with that occasional issue.
All that said, I still love these things -- one of the best purchases I've ever made.
