Distinct feature of canal type earphones is that it can prevent hearing-impaired caused by using long period of earphones because it was developed with bone conduction type. Particularly we were able to develop a technique and achieved patent (patent number No.10-1461188) by adding use of structure airflow so that it can prevent deafening caused by wearing earphone for a long term and made it harmless for ears. Also, DualS made result of first exportation to Japan in June, 2014 by getting recognition of newest technique Ø10 and we are planning to launch various products by using bone conduction vibrating device.
