1. What's special?

Headset uses the bone conduction speaker so the sound can pass through the skull directly to the auditory center, which eliminates many steps of acoustic transmission. It can achieve clear sound reduction in a nousy environment, so as to release the ears and revert to the delicate tone function.

Sports masks use one-way breathing valve. When one exhales, the silica films will bounce and discharge exhaled gas. It neither becomes stuffy, nor foggy when wearing glasses. When inhales, the silica films will fall, enabling the air to be breathed in through a cotton filter which can effectively filter out exhaust from automobiles and particulates that has the minimun diameter of 3 microns (less then PH2.5). The filter is of KN95 filter level which is especially suitable for sports like cycling and jogging.

2. How to wear?

Hang 2 at the back of the neck and tighten up using Velcro so that both sides of the speakers stay close to the cheek bone near the ears.
