WHY WE CHOSE IT
Engineered Endurance
Reaching for a charging cable mid-workflow breaks focus. To build a headline headphone for the catalog, the criteria were non-negotiable: over 40 hours of continuous playback, adaptive hybrid active noise cancellation that holds up in dense environments, and a structural frame that feels substantial without becoming heavy.
The development phase involved sampling dozens of prototypes across multiple manufacturing partners. Filtering for exact acoustic depth, weight distribution, and true noise isolation required stripping away anything that felt like a compromise.
This model emerged as the definitive choice. It delivers 46 hours of uninterrupted battery life, utilizes a four-microphone hybrid ANC matrix, and features a clean aluminum housing. Free of default logos or unnecessary visual clutter, it earns its place in the lineup through pure material quality and performance.
