Unique: The state-of-the art 56 mm ring
radiator transducers are the largest ever
used in headphones.
Extraordinary: The Gorilla glass directs
sound waves into dampened chambers
and drastically reduces distortion.
Perfect: The consistently balanced
connections ensure reliable signal
transmission to the transducers.
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.

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.

Important safety information
▷
Read this instruction manual carefully and completely before using the
product.
▷
Always include these safety instructions when passing the product on
to third parties.
▷
Do not use an obviously defective product.
Preventing damage to health and accidents
▷
Protect your hearing from high volume levels.
Permanent hearing damage may occur when headphones are used at
high volume levels for long periods of time. Sennheiser headphones
sound exceptionally good at low and medium volume levels.
▷
The product generates stronger permanent magnetic fields that could
cause interference with cardiac pacemakers, implanted defibrillators
(ICDs) and other implants. Always maintain a distance of at least
3.94"/10 cm between the product component containing the magnet
and the cardiac pacemaker, implanted defibrillator, or other implant.
▷
Keep the product, accessories and packaging parts out of reach of
children and pets to prevent accidents and choking hazards.
▷
Do not use the product in an environment that requires your special
attention (e.g. in traffic or when performing skilled jobs).
▷
Do not drop the product to prevent the glass panes of the ear cups
from shattering. Shattered glass can cause severe injuries.
Preventing damage to the product and malfunctions
▷
Always keep the product dry and do not expose it to extreme
temperatures (hairdryer, heater, extended exposure to sunlight, etc.)
to avoid corrosion or deformation.
▷
Do not place your headphones on a glass dummy head, chair armrest
or similar objects for long periods as this can widen the headband and
reduce the contact pressure of the headphones.
▷
Allow the product to stand for at least 2 hours before using it.
Condensation can form on the glass panes of the ear cups if the
headphones are moved from a cold environment to a warm
environment.
▷
Use only attachments/accessories/spare parts supplied or
recommended by Sennheiser.
▷
Clean the product only with a soft, dry cloth.
▷
Use the product with care and store it in a clean, dust-free environment.
