    Product Description

    Sennheiser HD820 dynamic closed headphones are built to allow music enthusiasts to appreciate audiophile level sound from anywhere they want even on the move.

    Equipped with distinctive glass transducer cases that lower resonance, the HD820 is easily the most lucid closed design in sound exceeding the achievements of previous similar models.

    New Audiophile Standard

    Typically, when it came to circumaural headphones the very best sound required an open back design. This axiom is now rendered obsolete by the youngest member of the Sennheiser Audiophile Range; The closed dynamic HD 820 employs an innovative technology for breathtakingly transparent and natural sound.

    The HD 820 has been developed and produced in Germany, to produce an incredibly naturalistic sound field, which is from Sennheisers attention to detail at every stage of the design process. The comfortable and plush microfibre ear pads and hand-built greatly reducing background noise while the sturdy metal headband features an inner restraining component.  One of the best Sennheiser headphones at this price, offering a superb level of detail whether you are at home, in the studio, or on the move

    Into the Great Wide Open

    Vibration, clear and lifelike. The soundscape of HD 820 is expansive and open which is rare for closed circumaural designs. Explore and revive your music in total reference standard without disrupting the hearing comfort zone of others. Not only is the sound field receptive, but there is also new places and prospects for musical enjoyment.

    Technology of Transparency

    The revolutionary translucent presentation of the HD 820 is accomplished using a superior technology; legendary Ring Radiator transducers which are fitted with unique covers. Exposing the aesthetics of the mechanism within, this stunning feature was initially created solely to service the sound.

    The concave glass replicates the sound waves from the back of the transducer to the absorber leading to least possible interference. Effectively, the sound waves are ‘gone’ as in open headphones.

    Excellent Components

    HD820 is distinguished through its exceptional attention to detail from the ultra-comfortable handmade earpads to the silver-cladded OFC cables and gold-plated plugs, to the robust metal headband with an inner damping element. This unmatched listening experience can be enhanced with the HDV 820 amplifier, the ultimate companion for HD 820.

    Audiophile Connectivity

    Only what gets in can eventually get out. For this reason, HD 820 is supplied with a purpose-tuned symmetrical, impedance-compatible cable with low capacitance and a balanced banana gold plug offering optimum traits in both contact resistance and sound.

    Superior Aesthetic

    A well-constructed hi-fi component must look good both inside and out; with unique glass covers, the HD 820's, are visually timeless and an innate technical asset.

    Press Reviews

    • 'The most capable pair of closed-back headphones we’ve tested. Robust, full-bodied and detailed sound, powerful, agile bass, solidly made, cleverly engineered...' (What Hi-Fi Magazine Aug 2018)

    • 'These Sennheisers are pretty big, but at 360g aren’t particularly heavy. Long-term comfort is good too, thanks to the carefully-shaped ear cups, the nicely judged clamping pressure that’s light but never loose and the fact the HD 820s never over-heat our ears.' (What Hi-Fi Magazine Aug 2018)

    • 'The HD 820s, like all the best recent models from Sennheiser, stick closely to the company’s trademark sonic signature. Once given a little time to warm up, you’re greeted with a smooth, full-bodied tonal balance that trades the last ounce of transparency and sonic agility for the kind of sound that’s easy to listen to for hours on end despite the quality of the recording.' (What Hi-Fi Magazine Aug 2018)

    • 'Further up the frequency range, we’re treated to crisp and articulate vocals brimming with expression, and highs that balance bite and refinement well. There’s no shortage of organisation either, with the headphones keeping track of the recording’s multitude of instrumental strands without losing composure.' (What Hi-Fi Magazine Aug 2018)

    • 'These headphones deliver music with a physicality most alternatives barely hint at, and this makes them all the more enjoyable. Dynamics shifts – both large- and small-scale are rendered with skill. The Sennheisers always sound controlled and organised.' (What Hi-Fi Magazine Aug 2018)

    • 'If you must have closed-back headphones and can stretch to the HD 820s,s you won’t be disappointed. They’re comfortable and obviously engineered to last. Most of all they’re hugely talented and rarely sound less than entertaining, almost regardless of source material. Highly recommended.' (What Hi-Fi Magazine Aug 2018)
