Open-Back Dynamic Headphone


Sennheiser HD 600 £399.00

Engineered for absolute clarity

The HD 600 is the audio purist’s choice for reference playback. An instrument of Sennheiser’s passion for perfect sound, the HD 600 is globally recognized as the standard for analytical high-fidelity listening – even 20-plus years after its release.

The HD 600 was developed to provide audiophiles an impartial scale of everything before the HD 600 in the audio chain.

Purpose-built to vanish when the listener presses “play”, the HD 600 is the benchmark reference headphone for both analyzing and enjoying a hi-fi setup. This disappearing act starts with an innovative, systematic approach to sound reproduction using transparency as the driving principle. Leveraging Sennheiser’s progressive production techniques and computer-based transducer optimization, the HD 600 perfectly fuses the art of sound with the science of it.

Opening Up Your Mind

The foundation of the HD 600 transducer system is an acoustically transparent open-back earcup, letting every single sound wave expand freely – a Sennheiser innovation pioneered and perfected for the most natural personal listening experience.

Sound emanating from the exclusive 42mm driver of the HD 600 is free from turbulence and distortion thanks to specialized acoustic silk controlling airflow—one of the finest materials for this task. Utilizing ultralight aluminum voice coils, the 38mm diaphragm of the HD 600 exhibits rapid rest and response times for clinical detail that never sounds harsh or hyped. Across the entire audible spectrum, this combination of driver size and integrity delivers an articulate response that is honest to the source. The 300-ohm impedance of the HD 600 presents a unified backdrop, allowing the nuances in music to leap forward like never 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 HD 600 reproduces mastering-grade sound independent of room acoustics or loudspeaker positioning.

Quality Control

Sennheiser worked tirelessly to build the HD 600 with the luxurious comfort and lasting durability audiophiles demand.

The velour padding of the HD 600 is supple for extended listening. Even the earcup grille pattern was crafted specifically for the HD 600 transducer system, guaranteeing a pristine personal sound experience. Assembled in Ireland at a state-of-the-art production facility, Sennheiser ensures attention to detail in handling a wide variety of acoustic materials. The production tolerances for the HD 600 are extremely tight, ensuring a consistent experience worldwide. For example, the resonators feature stainless steel mesh for uniform performance after manufacturing. Most parts on the HD 600 are modular, facilitating maintenance as the go-to reference headphones regardless of the listening space’s acoustics.

It’s All About Connection

Your HD 600 comes with a detachable, impedance-matched cable with ultra-low capacitance.

The ¼-inch / 6.3mm stereo connector of the HD 600 offers the audiophile-standard plug for connection to devices like headphone amplifiers, A/V receivers, digital audio players, analog gear, and more. At 9.8 feet / 3m long, it provides unencumbered listening on gear deep within shelves or in a favorite listening chair. A premium adapter is included to reduce the 6.3mm to 3.5mm / ⅛-inch for connecting to other audio devices.
