The HD 600 is the audio purist’s choice for reference
playback. An instrument of Sennheiser’s passion for perfect sound, it is
globally recognized as the standard for analytical high-fidelity listening -
even 20-plus years after its release.
The HD 600 was developed to give audiophiles an impartial
scale of everything before it 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
your 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, it perfectly fuses the art of sound with the science
Opening Up Your Mind
The foundation of the HD 600 transducer system is an
acoustically transparent open-back earcup that lets every single sound wave
expand freely - a Sennheiser innovation pioneered and perfected for the most
natural personal listening experience.
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.
We worked tirelessly to build a headphone with the luxurious
comfort and lasting durability audiophiles demand.
The velour HD 600 padding is supple to the touch for
extended listening at your hi-fi stack. Even the earcup grille pattern was
crafted specifically for this transducer system, guaranteeing a pristine
personal sound experience. The HD 600 is assembled in Ireland at a
state-of-the-art production facility with the attention to detail required to
handle a wide variety of acoustic materials. Our production tolerances are
extremely tight, ensuring that your HD 600 experience is consistent with those
all over the globe, whenever or wherever it was purchased. For example, the
resonators feature stainless steel mesh to guarantee uniform performance after
manufacturing. Most parts on the HD 600 are modular, making it a dream to keep
operational as the go-to reference headphones regardless of your listening
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 offers the
audiophile-standard plug for connection to devices such as headphone amplifiers
and A/V receivers, digital audio players, analog gear, and more. At 9.8 feet /
3m long, it offers unencumbered listening on gear deep within your shelves or
in a favorite listening chair. A premium adapter is included to reduce the
6.3mm to 3.5mm / ⅛-inch for plugging into countless other audio devices.
