Sennheiser HD 800 S Headphone

A Truly Masterful Headphone

The Sennheiser HD 800 S refines the brilliant sound image and impressive spatiality that made the original HD 800 cherished by music lovers worldwide, surpassing that already highly praised listening experience.

innerfidelity.com's Tyll Hertsens wrote that "the HD 800 S adds musicality to the legendary precision of HD 800, strengthening its position as the world's finest dynamic headphone... a masterful tweaking of this great headphone!"

Gear Patrol's Ian White called the HD 800 S "a revised version of the over-the-ear open-back Teutonic classics with new driver technology, even better construction quality, and a much smoother sound presentation."

Where the 2.2" Transducer Earns Its Keep

The Largest Dynamic Driver Available

Measuring 2.2 inches, the HD 800 S uses the largest transducer currently found in a set of dynamic headphones, with a patented ring-design diaphragm that minimizes distortion even at higher frequencies.

Total harmonic distortion stays below 0.02%, and the earcups are designed so sound waves reach your ear at a slight angle, producing a particularly natural, genuinely spatial sound perception throughout.

Absorber Technology, Borrowed From the IE 800

Innovative absorber technology, first introduced in Sennheiser's own IE 800 in-ear model, neutralizes the so-called "masking effect" entirely — the way louder low frequencies can hide finer high-pitched details in a recording.

By absorbing resonant energy, this technology prevents unwanted peaks in the frequency response, keeping even the finest musical nuances audible across the entire audible range from 4Hz to 51,000Hz.

Who Is the HD 800 S Best For?

• You want the world's finest dynamic headphone: that's not our language — it's how innerfidelity.com's Tyll Hertsens described it directly
• You have a genuinely comparable headphone amplifier: Gear Patrol notes this driver requires one to justify its asking price
• You want the largest dynamic driver available: at 2.2 inches, nothing else in this category moves more air
• You want a symmetrical balanced connection included: the XLR4 cable ships standard rather than as a separate purchase
• You want a fully open-back reference — the HD 800 S, Sennheiser's widest soundstage

How Does It Connect to Your System?

The HD 800 S ships with a symmetrical XLR4 cable, purpose-built for audio sources with a genuinely balanced output, such as Sennheiser's own HDVD 800 headphone amplifier and matching DAC unit.

A genuinely comparable headphone amplifier is essential here — this driver reveals every single limitation in a weak source rather than forgiving or masking it in any real way.

Pairs Well With

What finishes the system around an HD 800 S:

• Headphone amplifiers — genuinely essential to hear what this flagship driver is actually capable of
• Digital-to-analog converters — a high-quality DAC significantly improves what this driver has to work with
• Headphone cables — the included balanced XLR4 termination opens the door to reference-grade amplification
• Headphone stands — a proper resting spot for a genuine flagship instrument

Frequently Asked Questions

Do I need a high-end headphone amplifier?

Yes, effectively. Gear Patrol notes the HD 800 S "require[s] a comparable headphone amplifier to justify their asking price," and this driver reveals every weakness upstream.

How does this compare to the HD 820?

Both share the same 2.2-inch transducer platform, but the HD 820 is closed-back with unique glass transducer covers, while the HD 800 S stays fully open.

Can I use these away from home?

Not really. The HD 800 S is open-back and leaks sound significantly in both directions, so it's built for a quiet room rather than shared or mobile spaces.

What is the "masking effect," exactly?

An acoustic phenomenon where louder low-frequency sounds hide quieter high-pitched details from human hearing. Absorber technology neutralizes it, keeping fine nuances audible throughout.

Is the cable detachable?

Yes. The included symmetrical XLR4 cable is detachable, purpose-built for balanced sources like Sennheiser's own HDVD 800 amplifier and DAC combination.

Where is the HD 800 S made?

Manufactured in Ireland, the same facility responsible for Sennheiser's entire high-end reference headphone lineup, ensuring consistent quality across every single unit.
