I've mentioned before I have a set of Sony Bluetooth.  
Model #WI-C400.
I'm a side sleeper and these have been the only ones so far that I can fall asleep listening to without having pain in my ear. I use the smallest set of ear pads(it comes with 3 different sizes)
On occasion if I sleep too hard I wake up and have to pull them out because of soreness. That's the only negative thing I can say. The sound is good, price Is great, and the battery Is Something like 30 Hours of playtime so they can go days without charging.  
I love that fact.  
They're definitely worth telling my friends about so I wanted to tell y'all too. (Sounds like a paid endorsement,  it ain't.  Just a decent set of buds to meditate and listen to binurals with. )
Super cool! Thanks, I might have to review these...
