Bone Conduction Earphone

1. CNS-TS-V Model is a small volume and less weight communication equipment with high-performance headphones and microphone which is used in a dangerous environment. It can provide clear audio transmission under a very noisy environment.
2. CNS-TS-V Model makes your ears completely open, so that you could hear the tiny voice around you when you are communicating with others; it is different from the traditional headphone.
3. The voice information is collected by a high sensitive oscillationpick-up which is on the head, and sent to the skull's vocal cord, the vocal cord vibration transforms the voice information into sound signal.
4. CNS-TS-V Model will not affect other head protection equipments, like the helmet and respiratory mask, etc..
5. CNS-TS-V Model is ideal communication equipment in specific tasks in the field of military, law enforcement, fire fighting, rescue, heavy industry and so on. It is easy to operate.

Where it can be used?
It's perfectly used in the water or special work environment, such as underwater training spot or swimming center and surfing on the water. With the little gadget the couch do not have to shout at the trainee all the time, Its absolutely easy to use, just speak to your trainee or partners with the normal voice-volume to the boxes or the earphone

What's bone conduction?
Sound are decoded and converted into vibration on facial bone! directly received by cochlea----bypass eardrum. No electric-Magnetic wave.
In general, we believe listening to humans voice or the sound of music with ears only. But with the technology, the voice& sound generally transmitted by bone vibration, described as the bone conducted sound.

Advantage
1,Let ear absolutely free at the same time, you can still enjoy your normal conversation and listening to the surrounded sounds without removing the bone conduction headset
2,Hearing aid and protection, ok for people with hearing loss and impairment, and help prevent hearing deduction/loss
3,Even in high noise condition, you can hear the clear sounds by the use of ear plugs for the protection
4,perfectly used in the water or special work environment
