1. Open ear design, and you don't need to put the headphones in your ears or cover your ears. You will feel more comfortable.
2. Listening to the music and being aware of surroundings when you are running, cycling, jogging, climbing, driving, etc.
3. Non-ear or over-ear design effectively prevents damage to eardrums from being exposed to loud music.
4. When you don't need to use the Bluetooth headphones, you can just hang it around your neck. Only 0.04lb weight will not get any burden on your neck.
5. Regardless of you are exercising in the gym or exercising outdoors, the headset is too stable for a normal-sized head.
