Developed specifically to pair with WATATSUMI, this high-end line cable for portable audio has been newly designed from the wire material up.
Scheduled for release soon.
Exhibit Item ④: Display of MIKAGE – Brise Audio’s First Mass-Produced Earphone Cable
This is a display of MIKAGE, Brise Audio’s first mass-produced earphone replacement cable.
Although it is mass-produced, it lavishly uses the same high-performance, high-purity copper employed in our premium models.
It also features a simplified version of our proprietary high-quality sound processing, making it a cable that pushes the limits of what's possible in mass production in terms of both effort and cost.
As a new product nearing release, we invite you to experience it for yourself.
In addition, we will be bringing a variety of high-end cables for both earphones and headphones.
