1. When you first wear the rear mounted headphones, they may feel a bit tight and a bit pinched. But please rest assured that the more you wear, the more relaxed you become.
2. Open headphones, which means that when you play music, everyone else in the same room can hear it.
3. The headphones are rear mounted, please wear them at the back of your head and do not stretch them too far to cause the crossbeam to break
