In particular, by using the new bone conduction technology, the earphones directly deliver high-quality sound from a mobile device to users' auditory nerves via the cranial bone. That is, the sound is not delivered through the eardrum.

This product is in-ear-type earphones, so it looks just like conventional earphones. However, it has a 3.5mm hole on the inside of the ear tip.

This hole enables air to come in and out and users to hear clear sounds from the outside. It also protects users' ears as it does not damage the eardrum.

This product also enables not only ordinary people but also people with damaged eardrums, noise-induced deafness, and senile deafness to listen to mobile device audio.

Plus, the ear tip does not fall out often when users do intense exercise or move actively, as it is designed to be fixed onto earholes. In addition, it is resistant to sweat and moisture.

Joseph Baek, president of the EHPP division at DAESUNG M TECH, said: "The EHPP earphone is user-oriented. It is portable and easy to use. The product is an innovative solution that maximizes the advantages of both existing bone-conduction headphones and air-conduction earphones."

The EHPP division will officially launch its new bone-conduction earphones "EarSafe EI-01" on March 30.
