Sennheiser HD 800 S Dynamic Stereo Headphones (Wired, Black, XLR4 Connector)

Hear Your Music Life‑Size—And Every Microscopic Detail

Meet the reference every other over‑ear hopes to match. The HD 800 S delivers a panoramic, out‑of‑head soundstage with surgical imaging and low‑distortion detail that makes well‑recorded music feel breathtakingly real. If you’ve chased resolution only to be let down by glare or fatigue, Sennheiser’s absorber technology and ring‑radiator driver tame treble artifacts while preserving air and nuance—so you can listen longer, hear deeper, and simply get closer to the performance.

Why Audiophiles Choose This Product

• • Primary Benefit: Expansive, natural soundstage with laser‑precise imaging—often cited as “speaker‑like” in scale for headphones—without the etched glare of some analytical sets. Reviewers consistently praise the HD 800 S for its immersive stage and comfort during long sessions.
• • Technical Benefit: A 56 mm ring‑radiator dynamic transducer—the largest used in dynamic headphones—works with angled driver geometry and patented absorber technology to reduce resonant peaks, cut distortion, and preserve micro‑detail and timbral accuracy. THD remains exceptionally low at <0.02% (1 kHz, 1 Vrms).
• • Practical Benefit: Built for all‑day listening at just 330 g, with plush microfiber pads and even clamp force. Owners and testers note outstanding comfort and durability for marathon sessions.
• • Compatibility Benefit: True audiophile wired connectivity. The standard box includes a 3 m cable terminated 6.35 mm (¼") and a 3 m balanced 4.4 mm Pentaconn; an official 4‑pin XLR balanced cable is available—and commonly bundled in XLR‑focused variants like this one—to pair cleanly with desktop amps. Nominal impedance is 300 Ω with 102 dB SPL at 1 V, so a quality desktop amplifier unlocks full dynamics and EQ headroom.
• • Unique Benefit: Developed in Germany, precision‑built in Sennheiser’s Ireland facility with high‑precision ODU connectors, stainless‑steel driver baffles, and a layered headband that controls resonance—engineering choices you can hear.

Note: As an open‑back design, the HD 800 S is intended for quiet rooms; it leaks sound by design and does not isolate from ambient noise.

Product‑Specific Notes for Headphone Buyers

• Connectivity: Wired only; includes 6.35 mm and balanced 4.4 mm. Many XLR‑labeled bundles add a 4‑pin XLR cable; otherwise it’s an official accessory.
• Amplification: At 300 Ω and 102 dB/1 V, the HD 800 S plays from competent sources, but a quality desktop amp provides the voltage swing and control needed for full dynamics and EQ headroom—especially via balanced outputs.
• Sound Signature: Neutral‑to‑slightly‑bright with superb extension and air; absorber tech smooths treble peaks versus the original HD 800 for longer, more relaxed listening. Bass is tight and articulate rather than boosted.
• Comfort: Lightweight chassis, large cups, and microfiber pads are designed for hours of fatigue‑free listening.

Note: Because Sennheiser’s current standard box includes 6.35 mm and 4.4 mm cables with XLR‑4 offered as an accessory, contents in third‑party “XLR4 Connector” bundles can vary—always confirm the cable set with your retailer.
