Description
"This is where emotion is born."
The sound quality, which took about four and a half years to refine in the midst of the high-resolution sound quality environment, combines a robust mid-range with a sound image that provides a bird's-eye view of the overall sound. While focusing on the mid-range, which is important in music, the low and high frequencies can also be heard clearly.

Sound image that faithfully reproduces the performance space
The originally developed driver unit directly and accurately reproduces the high-resolution sound range that exceeds the audible bandwidth. The entire performance space, including the placement of the instruments and the airy atmosphere in which the sound resonates, can be widely viewed, and the sound quality is exactly the same as the original sound image.

Functionality and durability to withstand professional use
Silicon rings are used at the joints to thoroughly reduce noise that tends to occur when the body is moved. The ergonomically designed ear pads are sewn in three dimensions for comfort even when worn for long periods of time.
The durability of the moving parts and drop resistance have also been improved to achieve a quality that can withstand professional use.
