HD 600 – Engineered for absolute clarity, the HD 600 is the professional’s choice for reference playback. An instrument of Sennheiser’s passion for perfect sound, it is globally recognized as the standard for analytical listening in both technical and hi-fi applications—even 20-plus years after its release.

  • Acoustically transparent open-back earcups
  • Exclusive 42 mm driver and 38 mm diaphragm
  • Specialized acoustic silk controls airflow
  • Ultralight aluminum voice coils ensure excellent transient response
  • Detachable OFC copper cable
  • Impedance: 300 ohms
  • Frequency response: 12 – 40,500 Hz
  • Total harmonic distortion: 0.1%

X-Ray Specs

The HD 600 was developed to give engineers and 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 evaluating, mixes, masters, and even other audio components. 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 of it.

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 projects 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.

Quality Control

We worked tirelessly to build a headphone with the luxurious comfort and lasting durability studio professionals demand. The velour HD 600 padding is supple to the touch for extended listening at your DAW or 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 monitor regardless of your 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 offers the audiophile-standard plug for connection to devices such as audio interfaces, 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, studio, or desktop. A premium adapter is included to reduce the 6.3mm to 3.5mm / ⅛-inch for plugging into countless other audio devices.

Limited Experience with Higher Quality Headphones.

In all honesty, the tone of the customer service experience from SH as a whole, as someone with older phones looking for earpads SH has seemed a little offended at times. I have however had many years of excellent audio with 515s and 518s via 3rd Party Earpads. I had to go for the HD600 as a result as a gesture of solidarity and frankly the respected review Discord I use is fairly clear about their value. There were two other options the AKG and the HiFiMan's I think but the HD600 was a no-brainer really given my experience. Thus far I've been impressed with the extra detail and subtlety and I wouldn't say they've changed my life, but each time I listen to something new, I am listening to it for the first time given the output from these phones. I like the balance, not too bassy not too trebly! (sic) and I think they don't overpower my ears which are a little sensitive. The clamp strength is a little tighter than my old phones but that's normal. By no means painful and I've not been sore. Hugging might be the word! I am not familiar enough with this higher level of headphones to really state unequivocally if they are leaders in this price bracket but they've been really nice so far. I've just settled into them very easily. Like a more comfortable more luxurious version of an old familiar sofa but with a more detailed cloth. For £239 I think I will reflect on them being an excellent bargain.
