Newly developed air mechanism mounted (in A.I.R mechanism patent application)

Tornado equalizer, newly developed air mechanism in addition to the acoustic turbo circuit (A.I.R mechanism) High sealed with mounted, and achieve high sound insulation! A.I.R mechanism stands for Acousticinternal-pressureregulator.
To connect the space before and after the element in the acoustic resistance, by venting through a double high-cut filter the back of the sound, significantly reducing the sound leakage amount of treble. It also efficiently suppressed by the effect of a double filter ambient sounds. High-sealed, and achieve high sound insulation performance at a high level.

*1 Tornado Equalizer Circuit is Ocharaku’s patented acoustic technology
