Description

OVERVIEW:
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, it is globally recognized as the standard for analytical high-fidelity listening - even 20-plus years after its release.
X-Ray Specs: 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 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 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.
Quality Control: 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 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 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.

Common questions about buying open-box and refurbished.

Why buy refurbished or open-box?
Refurbished and open-box products offer the same performance as new at a fraction of the price. You're already saving $137 on this listing. They've been inspected, tested, and are ready to use — the only difference is the price tag. Buying refurbished also reduces electronic waste, extending product life cycles and keeping functional devices out of landfills.
What's the difference between open-box and refurbished?
Open-box products are customer returns that have been inspected and confirmed functional. They may show little to no use — often the item was returned simply because the buyer changed their mind. Refurbished products have been professionally repaired or restored by technicians, tested to meet or exceed manufacturer specifications, and sometimes come with a warranty. Both are a smart alternative to buying new.
Why use OpenBoxFox?
Finding refurbished deals is time-consuming — you'd have to check Amazon Warehouse, Reebelo, Dyson Outlet, and others separately for Sennheiser products. OpenBoxFox aggregates these listings in one place, so you can compare and find the best deal without the legwork. We update pricing daily so you always see current availability and real savings.
Is it safe to buy refurbished?
Yes. Products listed on OpenBoxFox come from established retailers like Amazon, Reebelo, and Dyson — not unknown third-party sellers. Each retailer has buyer protection policies, return windows, and in some cases warranties. You get the price advantage of used goods with the purchase security of a known retailer.
