Sennheiser HD820 - closed reference headphones (wired)

Sennheiser HD800 S - wired reference headphones, open

These groundbreaking closed dynamic headphones allow discerning music lovers to enjoy their music in audiophile quality wherever they want - at home or on the go. Its unique glass transducer covers reduce resonance to a minimum. This makes the HD 820 the most transparent sounding closed headphones in the world. It completely redefines the limits of sound reproduction in this headphone design.

The new audiophile standard for closed headphones
For audiophiles, there was never any doubt: to get the best sound from circumaural headphones, an acoustically open design is a must. This principle no longer applies. The closed dynamic HD 820, the latest member of the Sennheiser Audiophile series, features innovative technology that makes it sound absolutely transparent and natural. Developed and manufactured in Germany, it offers a breathtakingly natural sound image and is distinguished by exceptional quality down to the last detail. The soft, comfortable microfiber ear cushions are handcrafted and the robust metal headband has a sound-improving inner damping element. Look forward to an incomparable listening experience.

Wide, open sound landscapes
Lively, transparent, natural. The sound of the HD 820 breathes a generosity you wouldn't expect from a closed circumaural headphone. With the HD 820, you can explore and rediscover your music in absolute reference class quality - without disturbing the acoustic comfort zone of others. The HD 820 not only opens up new worlds of sound, but also new places and possibilities to enjoy your music.

Transparency that sets new standards
The HD 820's groundbreaking transparent sound was achieved through a special innovation: the legendary Sennheiser ring radiator converters are equipped with unique glass covers. This visually striking feature of the HD 820 reveals the fascinating appearance of its interior. But in fact it was developed exclusively for the service of sound: The concave glass reflects the sound waves from the back of the transducer onto an absorber. As a result, these sound waves "disappear" without a trace, similar to open headphones - resonances are thus reduced to an absolute minimum.

Perfect interplay of excellent components
100 percent "Made in Germany", the HD 820 is distinguished by its extraordinary attention to detail: from the particularly comfortable handmade ear pads that protect against ambient noise, to the silver-plated OFC cables and the gold-plated plug, to the robust metal headband with internal damping element. All this contributes to an incomparable listening experience. If you want to take this to the absolute top, you can combine the HD 820 with its perfect companion, the HDV 820 amplifier for dynamic headphones.

Audiophile connections
Impeccable sound quality requires high-quality signal transmission. That's why the HD 820 is equipped with a specially tuned balanced, low-capacitance, impedance-matched cable and a balanced, gold-plated 4.4 mm jack plug, which offers excellent characteristics in terms of contact resistance - and thus sound advantages.

The aesthetics of superior technology
A high-quality audio component always looks good - inside and out. This is impressively demonstrated by the HD 820 with its unique glass covers. It is an aesthetically timeless classic and a real technical beauty.
