I also had connection issues with bluetooth earbuds. (Not for cycling, just regular use). It bothered me to have the music cut out every once in a while. It wasn't a consistent issue, but enough to annoy me. I'm telling you, if you want amazing earbuds to ride with, buy the Bose IE2 sports. They are amazing. Never come out of your ear, no matter how much you sweat or how much it rains. They do not seal your ear so you can still hear, but they cover the entire ear opening so it is just the right amount of music and ambient sound for riding. 2 years of riding with them now and I am most certainly pleased. Dont see myself using anything else really.
