PRODUCT DESCRIPTION

Built with precision, purpose, and material integrity

The D1 is the world’s first dynamic headphone with a Thin-Ply Carbon Diaphragm (TPCD). Developed with Swedish company Composite Sound, specialists in advanced audio diaphragms, the D1 combines HEDD’s 40 years of acoustic expertise with advanced material science.

A new HEDDphone® built for true listening, the D1 delivers the clarity, realism, and tonal integrity of a reference monitor. Every note feels balanced and immediate, details are revealed without fatigue, and the carefully engineered fit ensures lasting comfort for extended sessions.

Thin-Ply Carbon Diaphragm

At the heart of the D1 lies a diaphragm made from Thin-Ply Carbon, an advanced composite used in extreme applications from Formula 1 cars to NASA’s Mars helicopter Ingenuity. In headphone design, it becomes something entirely new: TPCD eliminates the need for traditional damping at the diaphragm level, enabling faster, cleaner and more accurate performance.

Custom Dynamic Driver

Dynamic headphones have long balanced compromises such as speed versus stability or weight versus comfort. Drawing on four decades of R&D experience, and the expertise of Composite Sound, HEDD has engineered the core of the D1 driver to deliver studio-grade precision for personal listening. The result is sound that is detailed, balanced, and fatigue-free.

Universal Performance

With 32 Ω impedance and 100 dB sensitivity, the D1 performs consistently across sources from portable players to dedicated amplifiers. It also scales gracefully with higher-end systems while maintaining control and balance.

Designed and made in Berlin

All HEDD products are designed and assembled in Berlin by talented engineers and craftspeople who draw from a rich history in audio reproduction to create products tuned to the key of you.
