Engineering notes
- Closed-back cup with vents, EVA foam behind the driver to absorb high frequencies, and acoustic diffusers against standing waves
- Copper voice coil without a support (frameless) paired with the beryllium dome
- Earpad height split: 50% non-perforated leather for diffusion, 50% acoustic fabric over memory foam for absorption
- Headband and yoke mechanics developed for Utopia
Design language
Tailored and warm. Full-grain leather wraps the cups and the headband, cut and finished like fine leather goods.
