No rack required.
No stacking required.
No compromises.
What would it feel like if your high-fidelity audio system wasn't on a shelf,
but worn on your head?
A headphone with dual monaural amplification and a built-in vacuum tube preamp—it combines the warmth of vacuum tubes, the separation of a monaural amplifier, and the freedom of movement.


Born for the listener
This isn't meant to replace your audio system.
It's about taking its soul with you.
A simple question: How can you make the sound of a high-end audio system portable without compromise?
The answer lies in the architecture, not effects or analog. It boasts a signal path comparable to a professional two-channel system:
→ Reference-grade DAC captures every detail of the source
→ True tube preamplifier brings life to the midrange
→ Dual mono amplification maintains channel separation and stereo imaging
→ Firmware-level DSP tuning allows you to precisely adjust the tone to your personal preferences
Comfortable to wear and easy to carry. Designed for a true listening experience—while retaining the essence of Hi-Fi that will make you fall in love with listening.
