Sennhesier presents its new high-end HD820 headphones at the CES in Las Vegas.

They stand out for their transparent dome made of curved Gorilla Glass used to protect mobile devices, tablets……

The Gorilla Glass cover promises to enhance and create a truly incredible, realistic and natural sound scene.

Made 100% in Germany, its metal headband is covered with a microfiber and leather pad, the OFC cables have a silver coating with gold-plated connectors.

Its price will be around €2,400.00 VAT included.

With these innovative closed-back dynamic headphones, music lovers will be able to enjoy music at an audiophile level wherever they want, at home or on the go. With its unique transducer covers that minimize resonances, the HD 820 is simply the most transparent-sounding closed-back headphone in the world, pushing the boundaries of what has been achieved so far in closed-back headphone sound reproduction.

The new audiophile standard for closed-back headphones

Audiophiles were in no doubt: when it came to over-ear headphones, the best sound required an open-back design. This axiom has been made obsolete thanks to the youngest member of Sennheiser’s audiophile range: the dynamic and closed HD 820 uses innovative technology that achieves an overwhelmingly transparent and natural sound. Developed and manufactured in Germany, it offers a natural and incredibly realistic sound field, but also stands out for the extraordinary attention paid to every detail of its design. Its comfortable, soft microfiber ear cushions are handcrafted and offer excellent attenuation of ambient noise, while its sturdy metal headband includes an internal shock-absorbing element. Get ready for an experience like no other.

In the wide wide world

Vivid, wide, transparent, natural; The sound field of the HD 820 is very wide, which is not expected from closed circumaural headphones. With the HD 820 you can explore and rediscover your music in absolute reference quality without entering the aural comfort zone of your companions. Thus, the HD 820 not only expands the sound field, but also your ability to enjoy your music in new places and circumstances.

The technology of transparency

This advanced transparent performance of the HD 820 is achieved thanks to a special innovation: its legendary Sennheiser Ring Radiator transducers come equipped with exclusive glass covers. Revealing the exceptional appearance of the internal technical components, this striking visual feature was actually developed in the service of sound: the concave glass reflects sound waves from the rear of the transducer to a damper, so resonance is minimal. Thus, the sound waves “disappear” as they would in open headphones.

Excellent components of a stellar team

Made in Germany, the HD 820 also stands out for the extraordinary attention paid to every detail: from its comfortable hand-made ear cushions that isolate the listener from ambient noise, to the silver-plated OFC cables and gold-plated connectors, to the robust Metal headband with an internal cushioning element. This package offers an unparalleled experience, which can be further enhanced with the Sennheiser HDC 820 dynamic headphone amplifier – the perfect companion for the HD 820.

Audiophile connectivity

Only what goes in can come out. That’s why the HD 820 comes with a specially tuned, low-capacitance symmetrical cable and a 4.4mm balanced gold connector, which offers higher contact resistance and, therefore, better sound.

The look of superior quality

A well-designed audio component always looks good – inside and out. With its exclusive glass covers, the HD 820 model shows all the evidence to prove it. Its beauty is classic, aesthetically timeless and naturally technical.
