To get it out of the way, I am too cheap to spend $100 or more on bluetooth headphones. Like many, I want quality but don't want to pay the premium. I have searched quite a bit, and so far, I am impressed with these. Pairing was easy - and just take them out of the case and they sync to your phone. Seems to work well with one or two paired but I haven't tried one headphone for a prolonged period of time. Sound quality is very good. They stay in my ears (I have a larger ear canal) just fine during normal activitiy as well as while running or lifting weights. I really enjoy the ability to skip songs and adjust volume using the headsets, many simliar units do not offer this feature. A press on either earbud will pause/play - double press in the left or right will skip or reverse tracks, and a hold on either earbud will adjust volume. I haven't tried (and may not try) the microphone/voice communication feature, but if I find issues I will update my review. My only complaint is the case is kind of huge and putting in your pocket creates a huge bulge. If you could add some length and width to take away from the height, it would be a little more manageable to put in your pocket. I didn't take away stars because honestly, other than airpods, every other case I've seen is similiarly inconvenient, and also, I am not one who can't live without having headphones on my person and/or in my ears 24/7 (only use for fitness or walking), so it's less of an issue for me. I have been using for workouts for about two weeks now, so I can't speak to long term reliability, but again, if issues spring up with time, I will adjust my review.
