The HEDDphone D1 is a next-generation dynamic headphone designed for those who want reference-grade clarity and realism in every listening session. Built with HEDD's decades of experience in professional audio and cutting-edge materials from Composite Sound, the D1 delivers exceptional tonal balance, fast transients, and fatigue-free detail, all in a comfortable open-back design.
What sets the D1 apart is its use of a Thin-Ply Carbon Diaphragm (TPCD), the first of its kind in a dynamic headphone. Originally developed for high-performance industries like aerospace and Formula 1, this diaphragm offers precise structural resonance control. The result is faster, cleaner sound reproduction without the need for extra damping materials.
At the core of the D1 is a custom-engineered dynamic driver, tuned for studio-level accuracy with the smooth tonal character that makes long listening sessions enjoyable. This is a headphone built for both precision and comfort, featuring lightweight construction, velour ear pads, and a well-balanced fit that supports extended use.
The open-back circumaural design provides a natural, spacious soundstage, allowing you to experience mixes or music in a way that feels lifelike and immersive. With a 32-ohm impedance and 100 dB sensitivity, the D1 performs reliably across a range of devices, from portable players to high-end desktop amps, while still revealing more with premium equipment.
Every detail of the D1 reflects high standards of craftsmanship. It comes with premium textile-covered cables, a sturdy carry case, and a 5-year warranty after registration. As with all HEDD products, it's designed and made in Berlin, with careful attention paid to both sound and build quality.
