Comfort is maintained even during extended listening or production work. International audio communities have also praised the headphones for their “extremely comfortable fit,” with the spacious ear cups contributing to a relaxed wearing experience.

● Natural soundstage unique to an open-air design By reducing the sense of confinement often associated with closed-back headphones, the open-air structure creates a natural and spacious presentation where sound spreads freely throughout the environment. In addition to music enjoyment, they are also highly suitable for video production and instrument monitoring, making them an excellent choice for users seeking realistic spatial reproduction.
