Description

The HEDDphone® D1 is a precision-crafted open-back headphone designed to deliver studio-level clarity and natural sound reproduction. Created for listeners who demand accuracy and depth, the D1 reveals subtle details with ease while maintaining a smooth, fatigue-free presentation. Its lightweight frame, breathable velour pads, and thoughtful design make it a reliable choice for long sessions, from critical listening to casual enjoyment. The open-back architecture contributes to a spacious soundstage, allowing the music to breathe and feel true to life.

At the core of the D1 is a Thin-Ply Carbon Diaphragm, an advanced material adapted from high-performance industries like aerospace and motorsport. This innovation, developed with Composite Sound, gives the driver speed and control without relying on traditional damping. The result is a dynamic driver that captures transients cleanly and preserves tonal balance. With 32-ohm impedance and 100 dB sensitivity, the D1 performs consistently across a wide range of audio sources and scales well with premium systems. Hand-assembled in Berlin, it reflects a commitment to craftsmanship, acoustic precision, and long-term reliability.
