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 com-
bines, 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 am-
bient 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 cham-
bers. 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 de-
velopers 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.
Perfect: The consistently balanced Technology-wise, the HD 820 breaks fresh ground and, with its powerful,
neutral and transparent sound, sets a new benchmark for closed-back
connections ensure reliable signal
transmission to the transducers. headphones.
