I've been using them for a week or two now. The sound quality is good, better than cheap headphones. Bluetooth works well, although sometimes I have to re-pair with my iPhone 7plus to answer a call. Not sure what it is. Not a permanent problem, but something to keep an eye on. When it shows no headphones and no battery level in the phone window, it listens to music but it doesn't pair to the phone and I have to state this again in the bluetooth window and then everything is fine. This is a good quality blue tooth set. Better than regular cell phone bluetooth headphones and pretty good quality for ringtones. Exactly what the doctor ordered for club workouts, greatly enhanced by wireless connectivity. Worth the money and savings over Beats 3 or similar.
