These have great sound and noise cancelation while I'm on a call. The audio quality for music is great as well. I just wish it had foam tips as an option.
Great sound and easy to use. App is helpful so you can learn what pressing each button does, and change it to your preferences. Only issue is the case is slightly larger/heavier than what I would expect and what's ideal. Battery life is exceptional. Works for the gym (and stays in while exercising), general use, studying, and phone calls.
