HEDD Audio HEDDphone D1

HEDD Audio HEDDphone D1

The HEDD Audio HEDDphone® D1 is a bold redefinition of what a dynamic headphone can be. At its heart lies a world-first innovation — the Thin-Ply Carbon Diaphragm (TPCD) — an advanced composite material originally developed for extreme engineering applications, from Formula 1 racing to NASA’s Mars helicopter Ingenuity. In the D1, this technology becomes a new benchmark for speed, control, and transparency.

Every note feels immediate and balanced, revealing musical detail with precision yet without fatigue. The D1 captures the realism and tonal integrity of a high-end reference monitor — in a headphone built for true, long-form listening.

Thin-Ply Carbon Diaphragm – redefining the dynamic driver

The TPCD diaphragm eliminates the need for conventional damping materials. This allows the driver to move faster and more accurately, with exceptional transient response and reduced distortion. The result is a sound that feels effortlessly clear and stable — equally convincing in its microdetail and musical flow.

Reimagined Dynamic Architecture

For decades, dynamic headphones have balanced trade-offs between speed, weight, and tonal balance. Drawing from over forty years of professional studio experience, HEDD Audio re-engineered the core of the dynamic driver itself. The D1 achieves the precision and neutrality of a studio monitor while maintaining the warmth and fluidity that make listening deeply engaging.

Lightweight Comfort for Long Sessions

Despite its advanced driver design, the HEDDphone® D1 weighs only 350 grams. Every component — from the headband to the perforated velour earpads — has been designed for stability, even weight distribution, and lasting comfort. The result: hours of immersive listening without fatigue.

Universal Performance

With 32 Ω impedance and 100 dB sensitivity, the D1 pairs beautifully with both portable players and dedicated desktop amplifiers. It scales gracefully with higher-end systems while maintaining a consistent tonal balance and sense of control — a true all-rounder for discerning listeners.

Made in Germany

Each HEDDphone® D1 is crafted in Germany and fully serviceable, reflecting HEDD’s commitment to precision, durability, and sustainable design. Built with purpose and integrity, it embodies HEDD’s philosophy: great sound should endure. On Top of that, HEDD is giving 5 Years Warranty.
