By shaking the temporal bones on both sides, the sound is transmitted directly to the inner ear. The louder the sound, the stronger the vibration. Under normal circumstances, we recommend setting the volume to about 60%, which can meet the daily use needs and the vibration will not be too strong.

The earphone is made of titanium alloy after hanging material (memory alloy), which can restore the prototype even when bent at will. The clamping force on both sides is stable, so the wearing is very stable and won't fall off.
