The headphones are very light and soft, so they sit comfortably on the head. The sound quality is good. The size is adjustable over a wide range. Can be made very small. The earbuds don't feel strong, so I handle them with care. Although I've been using it for two years, and so far nothing has broken off. However, they clearly have some kind of problem with the microphone. This is my second pair of headphones. The first one was immediately replaced under warranty. The microphone didn't work at all. If you scream, it was barely audible. Secondly, it was already audible, but still had to speak very loudly. This is very uncomfortable, so I disconnected the microphone and use only headphones.
