Sennheiser HD 820

With a more than 70-year history of setting performance standards in sound, Sennheiser is once again redrawing the map with the creation of the HD 820. The new circumaural dynamic stereo headphones shatter expectations of what was thought possible from a closed-back model and set a new benchmark in sound quality for this type of design. The closed-back HD 820 headphones deliver astonishingly transparent sound, thanks to a unique glass transducer cover that minimizes resonances.

The HD 820 establishes a new reference standard for its class, with an incredibly realistic and natural sound field. This breakthrough performance has been achieved through a special innovation - Over each of the legendary Sennheiser Ring Radiator transducers are unique glass covers. Revealing the acoustics within, the patent-pending curved Gorilla glass serves to reflect the sound waves from the rear of the transducer to two absorber chambers, which results in minimal resonance.

Manufactured in Germany, the headphones feature a robust metal headband with an inner damping element, and silver-clad OFC cables and gold-plated plugs. Meanwhile, the earpads have been handcrafted from high-quality non-allergic synthetic leather and microfiber to cushion and insulate the listener from ambient noise. Together, these carefully selected components and materials delight every sense while producing an unparalleled listening experience.

Sennheiser's HDV 820 amplifier for dynamic headphones is the perfect companion to the HD 820. With its consistently symmetrical signal processing and extremely low harmonic distortion, the amplifier ensures unadulterated and perfect music enjoyment when paired with audiophile headphones. A specially tuned symmetrical, impedance matching cable with low capacitance is included with the HD 820 to guarantee seamless performance from this audiophile duo.

This offers a lower contact resistance than all other connections for headphones to produce minimal distortion and a more transparent sound reproduction. The new HD 820 will be available from early summer for $2,399. Info and photos by Sennheiser.
