The headphones work on the Air-conduction mechanism. They sound loud and clear. They are also bass rich, it's not that it does not have any bass at all. They are comfortable to wear for long periods becuase they sit on the area just after ear and it allows air to pass through the ear.

2. Good Battery life.
3. Rich sound , both bass and trebles are nicely heard.
4. Safe for ears during workouts, becuase we can hear the sound...
