First of all - these are not over-ear, they are on-ear. Even my 11yo daughter's ears could not fit in headphones. Overall, they are small - I felt an uncomfortable pressure every time wearing it; couple this with headphone size and you will get a headache after 1-2 hours.
Soundwise, they are great - reach bass, highs are good, and you can tune equaliser in the app. No complaints there.
Multipoint connection works, but you may need to power cycle them from time to time - they may get stuck and would not start playing music after phone call.
I bought them for conf calls mainly and had to return them after 2 days. They will pick up every high-tone sound around you (I was able to hear a fork fallen from the table behind the closed door, and that was really loud!). On top of all environmental sounds (someone speaking in the room behind the wall, typing etc) you can hear yourself very very loud. The worst part is that people on the other side would hear all these sounds as well.
