訳有り品 tomoworks revolve2.1+バランスケーブル

The arch part of the headband is partially damaged and reinforced with tape, so it is listed as a junk item.

Other than that, I believe it can be used without any particular issues.

A 4.4mm balanced cable is included.

Excerpt from the creator:
Handmade headphones REVOLVE2.1 by headphone builder TOMOWORKS.

These headphones allow you to switch between open-back and closed-back by rotating a knob.

Each unit is carefully crafted one by one using 3D printers and leather.
As I make them one at a time, I cannot produce many.
Work videos are also available on YouTube.

[Sound Quality]
This is a V-shaped sound signature with a focus on the quality of the bass.
In the closed-back state, there is relatively little sound leakage and the sound is well-balanced, but as you open it up, the soundstage expands and the bass increases.
With high resolution, crisp bass, and sparkling treble that just barely avoids being harsh, I think they are suitable for genres like rock and techno.
Tuned to make listening to music enjoyable, with an emphasis on punchy bass drums.

*From FirstREVOLVE to 2.0, the sound change between closed-back and open-back has been reduced, but the muffled sound in the closed-back state has been improved.

*2.0 → 2.1
Minor adjustments to the 3D data and changes to the screws have been made.
