Sennheiser - Setting the Standard Since 1945

Fritz Sennheiser founded his company in post-war Germany with just seven employees and a vision for perfect sound reproduction. Today, Sennheiser remains the reference standard in professional recording studios, broadcast facilities, and concert halls worldwide. The HD 800 S represents their pinnacle achievement in headphone design - the refined evolution of the legendary HD 800 that redefined what headphones could achieve. This isn't just their flagship; it's the headphone other manufacturers benchmark against.

The Summit of Headphone Engineering

The HD 800 S takes everything that made the original HD 800 legendary and addresses its only criticism - a slightly bright treble. Through meticulous refinement including an innovative absorber technology, Sennheiser achieved the impossible: maintaining the HD 800's revolutionary soundstage and detail retrieval while adding a more natural tonal balance. The result is nothing less than the most accurate headphone reproduction available at any price.

What sets the HD 800 S apart isn't just refinement but revolution. The massive 56mm Ring Radiator drivers - the largest ever used in dynamic headphones - create a soundstage that transcends the limitations of headphone listening. Close your eyes and you're not wearing headphones; you're sitting in the recording studio.

Revolutionary Ring Radiator Technology

• 56mm Ring Radiator Drivers: Largest transducers in dynamic headphones minimize distortion
• Absorber Technology: Precision damping eliminates the 6kHz peak for natural treble
• Open-Back Excellence: Unrestricted airflow creates unlimited soundstage depth
• 300Ω Impedance: Optimal for high-end headphone amplifiers
• Hand-Selected Drivers: Matched pairs ensure perfect channel balance
• Microfiber Earpads: Luxurious comfort for extended listening sessions
• Aerospace Materials: Carbon fiber-reinforced headband for strength without weight

The Soundstage That Defies Physics

The HD 800 S creates a spatial presentation that shouldn't be possible with headphones. Instruments occupy distinct positions in three-dimensional space. The concert hall's acoustic signature becomes palpable. Front-to-back layering rivals the best speaker systems. This isn't the typical "three blob" headphone imaging - it's a continuous, coherent soundfield that extends beyond your head.

The Ring Radiator's angled positioning directs sound from the front, mimicking natural hearing. Combined with the massive driver surface area, this creates an out-of-head experience that makes other headphones feel claustrophobic by comparison.

Resolution Without Fatigue

Where the original HD 800 could become analytically bright, the S version achieves a perfect balance. The absorber technology specifically targets the 6kHz resonance that caused listener fatigue, smoothing the response without sacrificing detail. You hear everything - the pianist's breathing, the violin's rosin, the studio's air conditioning - but presented musically rather than clinically. This is resolution in service of music, not metrics.

Built for Endurance

Despite their sophisticated technology, the HD 800 S are built for daily use. The reinforced headband distributes the 370g weight evenly. Microfiber earpads remain comfortable during all-day sessions. The detachable cables - both balanced and single-ended included - use robust connectors that withstand thousands of insertions. This is reference equipment designed for professional reliability.
