Sennheiser HD 820
The new benchmark among closed-back headphones
The Sennheiser HD 820 opens up new tonal horizons and takes you into a world full of musicality, passion and emotions – regardless of whether you enjoy your favorite music at home or on the go.
After extensive research and development work, our engineers have succeeded in bringing the best of both worlds together – the HD 820 com­bines, without compromise, the transparency and naturalness of the best open-back headphones with the sovereignty and serenity of closed-back systems.
The trend-setting design of the HD 820 not only effectively reduces am­bient noise, but also ensures an ultra-low bass reproduction and a clear reproduction of mids. This is possible due the HD 820's patent-pending acoustic diffraction housing – recognizable by the two glass panes behind the transducers.
Extremely stiff, convex elements made of Gorilla glass and shaped using a specially developed process specifically direct the sound, which is emanated from the diaphragm towards the rear, into dampened cham­bers. Therefore, reflected sound waves have virtually no chance of disturbing the movement of the HD 820's advanced 56 mm transducers and of compromising the precision of the audio reproduction.
To ensure perfect sound quality and ultimate wearing comfort, our de­velopers have carefully thought through every detail of the headphones. The crucial parts of the headphones are made from advanced materials – materials that are also used in the aerospace industry for their low weight and high stability.
Due to its double-shell construction, the housing of the Sennheiser HD 820 is extremely lightweight and stiff. The headphone yokes guarantee a lasting, comfortable fit and are the result of complex mechanical strength simulations and field tests. The supplied connection cables ensure perfect contact between the headphones and any source device, be it mobile or stationary.
The unique quality of these headphones is guaranteed and backed by our name. Each Sennheiser HD 820 is therefore delivered with a signed chart providing its individually measured frequency response curve and serial number.
Technology-wise, the HD 820 breaks fresh ground and, with its powerful, neutral and transparent sound, sets a new benchmark for closed-back headphones.

The acoustic diffraction housing

Besides the advantage of isolating external noise and leakage from inside, closed-back headphones offer excellent reproduction of low tones and bass. Decisive for an as spatial and airy sound reproduction as possible, however, is an optimal damping behavior which ensures that, despite profound basses, the mid-range and high frequencies are not affected negatively.

Reliable: The high-precision ODU connectors and balanced connections ensure safe signal transmission.
The HD 820's patent-pending acoustic diffraction housing with its convex glass pane made of Gorilla glass ( 1 ) provides an optimal damping behavior. The sound waves ( 3 ) produced by the diaphragm ( 2 ) are reflected by the hard surfaces of the diffraction housing and directed in a controlled manner into the ring-shaped absorber elements ( 4 ) located around the transducers.
The pressure and speed of the sound waves are therefore always controllable and negative side effects are avoided. The result is a clear, interference-free and spatial sound reproduction over the entire frequency spectrum, from about 6 Hz to 48,000 Hz, which is unequaled in closed-back headphones.

Reference diffuse-field frequency response curve
The individually measured diffuse-field frequency response curve for your HD 820 headphones can be found on the supplied USB flash drive. The reference diffuse-field frequency response curve can be found on the inside cover page.
What is the diffuse-field frequency response curve? In an anechoic chamber, 8 highly linear loudspeakers emit noise signals independently of each other. In the central area of the chamber, the various sound data meet and are superimposed on each other to form a diffuse field, in which it is no longer possible to determine from which direction the sound is coming. This noise is then varied in distances of a third and reproduced alternately over the speakers and the headphones to be measured. A large number of test persons then evaluate the difference in volume between the room noise and the noise in the headphones.
The ideal state is when the volume impression between the diffuse field and the headphones is the same. Diffuse-field equalized headphones provide a clearly more spatial impression and make it easier to determine whether sounds are coming from the front or rear. Put simply, the sound events take place outside the head and are not confined to the space between the ears.
