Sennheiser HD 800 S – Features, Performance, and Audiophile Experience

The Sennheiser HD 800 S represents a reference standard in open‑back wired headphones, offering expansive soundstage, detailed audio, and exceptional build quality for critical listening and professional use.

1. Introduction: Reference‑Class Listening

The Sennheiser HD 800 S is designed for audiophiles and professionals who seek lifelike audio reproduction with exceptional clarity and spatial detail. As an evolution of the acclaimed HD 800 series, it builds on long‑standing engineering expertise to deliver a sound that is both natural and immersive — ideal for critical listening, mastering, and enjoying high‑resolution music. :contentReference[oaicite:0]{index=0}

Unlike typical consumer headphones, the HD 800 S focuses on delivering a wide soundstage and neutral tonal balance, making it less about exaggerated bass and more about accurate representation of source material. :contentReference[oaicite:1]{index=1}

2. Design and Build Quality

The HD 800 S features a premium construction that reflects its high‑end positioning:

• Open‑back, circum‑aural design promoting a natural sound field with minimal resonance. :contentReference[oaicite:2]{index=2}
• Handcrafted ear pads made of high‑quality microfiber for comfort during extended listening sessions. :contentReference[oaicite:3]{index=3}
• Matte black metal components give a modern and robust aesthetic. :contentReference[oaicite:4]{index=4}
• Adjustable metal headband with a damping element reduces unwanted vibrations. :contentReference[oaicite:5]{index=5}

Weighing approximately 330 g, the HD 800 S feels substantial yet balanced, suitable for long sessions without causing fatigue. :contentReference[oaicite:6]{index=6}

3. Open‑Back Architecture and Soundstage

The open‑back design is a hallmark of reference‑grade headphones, and the HD 800 S masterfully employs this principle. By allowing sound to radiate both forward and backward, this architecture creates a more “speaker‑like” experience where the sound feels spacious and enveloping. :contentReference[oaicite:7]{index=7}

Critics and users alike highlight its wide and deep soundstage — where instruments seem to emanate from distinct locations around the listener rather than from inside the head. :contentReference[oaicite:8]{index=8}

4. Transducer Technology: 56mm Ring Radiator

At the heart of the HD 800 S is a **56 mm ring radiator transducer**, a unique dynamic driver design that differs from conventional diaphragms. :contentReference[oaicite:9]{index=9}

• Large diaphragm size enables improved air movement for nuanced sound reproduction. :contentReference[oaicite:10]{index=10}
• Ring radiator configuration maintains rigidity and reduces distortion in higher frequencies. :contentReference[oaicite:11]{index=11}
• Paired with a 40 mm voice coil, the system achieves a precise and controlled response. :contentReference[oaicite:12]{index=12}

This engineering results in a frequency response that extends from very low to very high ranges, capturing subtleties that many headphones cannot. :contentReference[oaicite:13]{index=13}

5. Absorber Technology for Detail Retrieval

A key innovation in the HD 800 S is its patented **absorber technology**. This system reduces resonance‑induced masking — a phenomenon where louder frequencies can hide quieter ones. :contentReference[oaicite:14]{index=14}

By minimizing unwanted peaks and smoothing the acoustic response, the absorber uncovers fine details that contribute to a more transparent and precise listening experience. :contentReference[oaicite:15]{index=15}

6. Comfort and Ergonomics

Comfort is crucial, especially for reference headphones intended for lengthy sessions. The HD 800 S delivers here with:

• Large circumaural pads that encircle the ear without pressing too tightly. :contentReference[oaicite:16]{index=16}
• Soft microfiber padding that reduces pressure and heat build‑up. :contentReference[oaicite:17]{index=17}
• Dual‑axis articulating earcups that adapt to individual head shapes. :contentReference[oaicite:18]{index=18}

While widely comfortable, some users note that the open design and low clamp force may require adjustment to find a perfect fit. :contentReference[oaicite:19]{index=19}

7. Sound Quality Overview

The HD 800 S is designed to provide neutral, natural sound that avoids coloration. The overall signature leans toward realism and detail rather than exaggerated bass or emphasis. :contentReference[oaicite:20]{index=20}

Reviews consistently highlight:

• Wide and immersive soundstage that extends beyond the listener’s head. :contentReference[oaicite:21]{index=21}
• Expressive midrange with detailed vocals and instrument timbres. :contentReference[oaicite:22]{index=22}
• High‑frequency clarity that reveals delicate textures. :contentReference[oaicite:23]{index=23}

Bass is accurate and controlled, though not emphasized in a manner typical of consumer‑oriented headphones — reflecting its reference‑grade tuning. :contentReference[oaicite:24]{index=24}

8. Technical Specifications

Key technical specifications of the HD 800 S include:

• Open‑back dynamic design with 56 mm ring radiator transducers. :contentReference[oaicite:25]{index=25}
• Frequency response: 4 Hz – 51 kHz, offering extended range beyond typical headphones. :contentReference[oaicite:26]{index=26}
• Impedance: 300 Ω — best paired with dedicated amplifiers or audio interfaces. :contentReference[oaicite:27]{index=27}
• Low total harmonic distortion (THD): <0.02 % for clean audio reproduction. :contentReference[oaicite:28]{index=28}
• Weight: ~330 g (without cable). :contentReference[oaicite:29]{index=29}
• Detachable cables with both balanced 4.4 mm and 6.35 mm connectors included. :contentReference[oaicite:30]{index=30}

9. Connectivity and Cabling

The HD 800 S comes with high‑quality detachable cables:

• A 6.35 mm (¼″) jack cable for traditional Hi‑Fi systems. :contentReference[oaicite:31]{index=31}
