DualS is compound word that stands for Dual Sound and also it is a implication word that has meaning of playing two tones simultaneously from one set of speakers. DualS specializes in sales and developing of bone conduction product. DualS has know-how that accumulated for a long time and gain competitive advantages over other companies and have been developing and releasing of new product consistently. Especially, we were able to develop a bone conduct vibrating device that has the minimum size(10mm*5mm) and the lightest weighing(0.8g) but still able to succeed secure the best sound quality than existing vibrating device.

 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.

DualS will continuously search and develop techniques of other product field such as electronic appliance, special audio equipment and radio.
