They fit a bit snug on the sides, however, which started out as comfortable, but over the course of a weekend started to get annoying. I use mine at home, mostly for playing my iPhones books on tape. Im still on the fence if Im going to return these. But it cannot be used while charging and only uses micro-USB. A gold mine of information. The support sports ear hooks make sure they are tight and dont fall off. I do absolutely love how easy it is to put together, my mom and I installed it together and shed never used a power drill before. The first time they sent me size 39 "Yara" style. The company has great customer service however and reached out to us to apologize and to make things right. They do turn on and pair however the volume is stuck on MAX and you cannot press the down button to disengage it or change the volume.
