High-quality High-resolution In-ear Headphone

In response to the latest trends in smartphones and other portable music players, Hosiden has developed compatible high- resolution in-ear headphones.
Capable of high sound pressure levels enabling highly responsive sound reproduction; by optimizing the design of the ducting, the high-frequency characteristics of the in-ear headphones have been improved. Our focus has been the creation of a more natural sound, regardless of the sound source, through tuning, giving consideration to the balance of the sound at low frequencies, and without emphasizing the high-resolution capability at high frequencies only. Use of brass in the casing has realized clear sound quality and high texture quality with minimum case vibration. Also, texture has been luxury by hair-line pattern.
These in-ear headphones will be marketed under the SATOLEX brand name, which is our sales subsidiary.
