Audiophile-quality professional stereo headphones, the Sennheiser HD 600 utilizes two-layer diaphragm technology to radically reduce surface born resonance. A powerful neodymium ferrous magnet is optimized to control the motion of the diaphragm, which provides deeper bass without the loss of definition.

Complementing the diaphragm and driver magnets are triple wound aluminum voice coils, which are housed in an acoustically transparent ear cup, maximizing the benefits of the open design. The HD 600 is an ideal choice for the professional recording engineer, providing an uncolored and spatially accurate rendition of program material, especially classical music.

Engineered for absolute clarity, the HD 600 is the audio purist’s choice for reference playback. 

The foundation of the HD 600 transducer system is an acoustically transparent open-back earcup that lets every single sound wave expand freely.

Sound emanating from our exclusive 42mm driver is free from turbulence and distortion thanks to a specialized acoustic silk that controls airflow—one of the finest materials available for this task—while requiring hand assembly. By using ultralight aluminum voice coils, the 38mm diaphragm exhibits rapid rest and response times for clinical detail that never sounds harsh or hyped. Across the entire audible spectrum of sound, this combination of driver size and integrity delivers an articulate response that is honest to the source—the kind of listening experience required to absorb the details with confidence. The 300-ohm impedance of the HD 600 presents a unified backdrop that allows the nuances in your music collection to leap forward like you have never heard before. Each transducer is measured against rigid standards for consistent performance across the entire frequency spectrum in both channels. By reducing variances between left and right channels, the headphone reproduces mastering-grade sound independent of room acoustics or loudspeaker positioning.

The velour HD 600 padding is supple to the touch for extended listening. Even the earcup grille pattern was crafted specifically for this transducer system, guaranteeing a pristine personal sound experience.
