The New Audiophile Standard in Closed-Back Headphones Features Innovative Glass Transducer Covers: Sennheiser HD 820 Plays with Incredible Transparency, Openness, Naturalism, and Realism
Open-back headphones' audiophile superiority is dead, long live the dynamic closed-back design! Indeed, the groundbreaking Sennheiser HD 820 headphones put a decisive and firm end to the long-held axiom that in order to get the finest sound, music lovers had to opt for an open-back model. Developed and made in Germany, HD 820 features innovative technology – namely, unique glass covers fitted on Senheiser's hallmark Ring Radiator transducers – responsible for its incredibly transparent, open, natural, and realistic performance. These striking components' concave glass material and shape reflect sound waves from the rear of the transducer to an absorber, resulting in minimal resonance – just like what happens in open-back types. And yes, as you can see, these glass covers also look supremely cool on the outside.
While HD 820 promises to take you into the great wide open of your music like you've never before experienced from a closed-back model, it will also bathe you in luxurious comfort and spoil you with finite details. From the extra-soft, handcrafted, microfiber ear pads that insulate you from hearing ambient noise to a robust metal headband with inner damping element, HD 820 remains focused on the extraordinary. Silver-cladded OFC cables and gold-plated plugs, a specially tuned symmetrical, impedance-matching cable with low capacitance, and a balanced 4.4mm gold plug that provides superior contact resistance round out a pair of ‘phones that redefine the category.
Built to extremes by Sennheiser, one of the foremost and longest-trusted names in headphones, HD 820 sets a new standard you simply need to hear. 100% Music Direct Guaranteed.
"The intimacy of the HD 820 is uppermost."
– Alan Sircom, Hi-Fi+
