A New Chapter in HEDD's Legacy: Carbon Technology Serving Headphones
With the HEDDphone D1, HEDD Audio transfers over
40 years of acoustic expertise, carried by the design heritage of
Klaus Heinz, into a next-generation dynamic headphone. Its uniqueness lies in the use of a rare material in audio,
Thin-Ply Carbon, already proven in extreme environments, to optimize stiffness, mass, and resonance control. The D1 was
co-developed with Composite Sound (Sweden), specialists in ultra-light and highly rigid composites, aiming for coherent, modern, and durable sound reproduction.
Who Is the HEDDphone D1 For and What Are Its Best Uses?
The D1 is designed for producers, sound engineers, and musicians seeking reference-grade headphone listening while maintaining a spatial feel close to monitoring. Its
open architecture highlights stage depth and element localization, useful for adjusting reverbs, panning, balances, and micro-dynamics. Thanks to accessible impedance and good sensitivity, it integrates well with both audio interfaces and high-end headphone amplifiers, delivering sound that gains solidity and nuance as the signal chain quality improves.
TPCD Diaphragm, Custom Driver, and Open Design: The Recipe for Speed and Accuracy
TPCD: Clean Transients and Resonance Control
The
Thin-Ply Carbon Diaphragm (TPCD) is designed to optimize structural resonance control. In listening, this translates to sharp attacks, fine texture rendering (strings, vocals, percussion), and a sense of cleanliness in dense passages, without unnecessarily hardening the high frequencies.
Custom Dynamic Driver: Precision, Speed, Tonal Balance
The D1 features a
custom dynamic driver developed with Composite Sound, targeting a rarely combined set of qualities:
speed,
tonal balance, and
image stability. The result is a headphone suited for critical decision-making (EQ, compression, de-essing) while remaining comfortable over long periods.
Studio-Designed Connectivity: Detachable, Robust, Ready to Work
The
dual 3.5 mm mono input connectors and
two detachable textile-sleeved cables facilitate integration in studio environments and maintenance. The package is completed with a 6.35 mm adapter and a dedicated carrying case.
