I've had these for a few months now. I have other BT headphones, but wind up with these more. I like the fit, I like the ear loop things. They keep the headphones in place well, the controls are straight forward and simple.
My one beef. They're not that loud. Full blast sounds like 6-7. Battery life could be better, but I could have opted for a model up. The range is not great. You walk away from your device, you'll lose signal quickly.
For the price, in theory I can't complain, which is why I'm going 4 instead of 3 or 5. If you want a good set of headphones for the gym or for watching YouTube at Starbucks, they're great. If you want to jam out, have them under your helmet for a ride, they won't be loud enough.
