Just got the Jaybird BlueBuds X yesterday and LOVE them. The tips aren't the most comfortable, but I got some Comply foam tips and now they're perfect. Great sound isolation, sound quality, all day (more like multi-day) battery life, great connection with no distortion or drops in quality, and most importantly... No delay when playing music through the headphones.
What I mean is when connecting the headphones to my Mac or iPhone, when I play a video the audio syncs in realtime. With the wireless Powerbeats 2, there was a delay where the video would show people speaking, but you wouldn't hear the audio until ~2-3 seconds later which was jarring and annoying.
