The HD 600 is the audio purist’s choice for reference playback. An instrument of Sennheiser’s passion for perfect sound, it is globally recognised as the standard for analytical high-fidelity listening - even 20-plus years after its release. The foundation of the extraordinarily clear sound of the HD 600 is its’ open acoustic design and the revolutionary transducer, which has been computer-optimized to reduce partial vibrations, which are responsible for a multitude of distortions.

Designed to create pure emotional connection, this dynamic open-back circumaural headphone invites you to disappear into music with vivid realism and effortless flow. A precision-tuned 50 mm driver with an advanced dual-composite diaphragm balances speed, control, and rich dynamics, delivering clarity, imaging, and full-bodied vocals that feel alive. Its open acoustic architecture enhances air and depth while remaining easy to drive from portable devices or home systems. Crafted for long listening sessions, the lightweight frame combines sustainably sourced walnut wood, metal reinforcements, vegan leather, and soft velour pads for exceptional comfort and durability. Built to be serviceable and enduring, it reflects a thoughtful approach to sound, materials, and longevity.
