Varimotion speaker
High-precision
two-layer diaphragm
The diaphragm is made of two
different plastic foils for optimum
vibration performance.
The diaphragm is the most important
part of the speaker capsule.
Acoustical engineers require this
extremely thin piece of foil to perform
the most spectacular feats.
High-performance
cable with 1/4"
jack plug
The single, 99.99% oxygen-free cable
provides consistently excellent audio
and is terminated in a 1/4" jack plug
for connection to any 1/4" headphone
output.
Self-adjusting
headband
The headband optimally adjusts to
your head to ensure perfect fit.
An ideal diaphragm should combine
high compliance around the perimeter with a piston-like motion in the
center. The patented Varimotion
diaphragm from AKG does exactly
that. It is thicker in the center than
around its perimeter so it moves like
a piston and is immune to partial
oscillations. The result is absolute
accuracy, better imaging and clarity
at high frequencies.
Replaceable ear pads
are made of breathing,
skin-compatible material and
easy to clean.
Being thinner around the rim, the
so-called movement zone, the diaphragm will vibrate more easily to
provide a very powerful bass range.

AKG Surround
Technology
LOGIC7-Decoder
Dolby Surround
Pro Logic Decoder
Movie soundtracks are usually
mixed down to four channels. Left
and Right are the same two channels used for hi-fi stereo. The third
channel is the Center channel projected from above or below the
video screen. The fourth channel is
called “surround” or “rear” and is
usually projected by two loudspeakers placed behind the listeners.
These four channels are encoded by
a special circuit and recorded in
“piggyback” fashion on the two
stereo tracks. This allows the
signal to be reproduced in mono,
stereo, or (using a decoder) through
four separate channels. For
surround reproduction, the signal
needs to be decoded. This is the job
of the Dolby Surround decoder.
Dolby Digital Decoder
The digital multi-channel format of
Dolby Laboratories, Inc. used in
advanced commercial theater
equipment is the most widespread
digital surround standard for DVDs,
laser discs, and digital TV. The distinguishing feature of Dolby Digital
is that all tracks (five audio tracks
plus one subwoofer track) are
stored separately in digital form.
These discreet channels allow an
optimized spatial sound to be generated that can be processed in the
digital domain by IVA without any
degradation of sound quality.

Up to now, the latest development
by the innovative engineers at
LEXICON was only used in highquality, high-end processors. Now,
the unique advantages of the
LOGIC7 decoder are available for
headphones for the first time.
The LOGIC7 decoder automatically
identifies the input signal as mono,
stereo, or surround encoded and
processes the signals appropriately.
The LOGIC7 decoder uses the
localization cues contained in
stereo signals to generate a 3-D
sound that conveys to the listener a
sense of envelopment in the sound
rather than standing in front of a
pair of loudspeakers. Surround
encoded signals are reproduced
exactly as defined in the mix.
Along with the standard 5.1 surround format, LOGIC7 also provides
left and right side channels, for a
total of seven loudspeaker channels plus one subwoofer channel.
In addition, another surround
center channel is added in the
headphone mode. In conjunction
with IVA processing, LOGIC7
provides its full performance level
with eight virtual loudspeakers.
The result is far more natural and
accurate imaging.
SURROUND
IVA processing
Patented AKG IVA processing for
spatial sound is the heart of each
HEARO surround headphone system. IVA provides natural (binaural)
imaging through headphones in a
similar way as if you were listening
to a pair of loudspeakers.
Binaural sound:
A Sound waves from a given source
arrive at one ear earlier than they do
In short, IVA processing provides a
perfectly natural, spatial (binaural)
sound through headphones.
DIGITAL transmission
Digital transmission ensures pristine
surround sound with a CD-level
dynamic range and no perceptible
noise. Digital radio links are immune
to interference and “jamming” from
devices emitting RF radiation such
as TV sets or computers.
at the other, and they “look” different, too. Amplitude and phase
shifts allow us to localize a sound
source in space.
B Headphones usually eliminate
these important amplitude and phase
shifts. Sound sources are perceived
as being inside the head rather than
in the room.
C IVA processing developed by AKG
adds to a stereo signal the amplitude and phase shifts that are necessary to create a sense of natural,
spatial, “outside the head” imaging.
Eight-channel
surround
Eight-channel surround is an improved version of the internationally
accepted five-channel format. The
new format models eight virtual loudspeakers distributed around the
room. The result is an incredibly
spacious sound. Eight-channel
surround requires a LOGIC7 decoder.
Ear matching curves
Sound waves from a given source arrive at one ear earlier than they do at
the other, (see also “IVA processing”,
para A) because the head, trunk, and
ears cause amplitude and phase
shifts. All these changes can be illustrated by so-called “head-related
transfer function”. Since these curves
differ from person to person, everyone
perceives sound in a different way.
Ear matching curves are electronic
models of outer ear transfer curves
that match the headphone’s sound to
the user’s acoustic perception.
Digital antenna
diversity
Diversity reception is normally
used in professional wireless
microphone systems to ensure
perfect reception even under
extremely difficult conditions. An
adaptive algorithm makes sure
the antenna that delivers the
better signal is always active to
prevent dropouts.
VMAx
VMAx provides surround sound from a
pair of stereo loudspeakers, with no
extra hardware. All you need is a stereo amplifier and speakers. The VMAx
processor simulates the envelopment
of surround sound.

Self-adjusting
headband
The headband automatically adjusts
to your head to ensure a perfect fit.
The headband also takes the weight
of the headphone off of your ears and
distributes it on top of your head.
High-capacity
rechargeable batteries
The supplied batteries have a long
life, with no risk of overcharging and
minimum memory effect.
Speech optimized
response
AKG TV headphones boost the
frequency range of human speech.
Therefore, dialogue will be more
intelligible amid the ambience, sound
effects, and music, making it easier
to catch all the subtle nuances of
your favorite actor’s voice.
3 in 1
The transmitter serves as a storage
cradle and battery charger for the
headphones. As soon as you place the
headphones on the transmitter
cradle, battery re-charging starts
automatically.
Balance control
Everybody perceives sound differently,
and there may even be differences in
sensitivity between your left and right
ears. The balance control lets you
adjust left and right volumes for an
optimally balanced sound.
Patented AKG
Varimotion diaphragm
The diaphragm is the most important
part of the speaker capsule. An ideal
diaphragm should combine high
compliance around the perimeter with
a piston-like motion in the center.
The patented Varimotion diaphragm
from AKG does exactly that. It is
thicker in the center than around its
perimeter. The result is absolute
accuracy, better imaging and clarity
at high frequencies. Being thinner
around the rim, the diaphragm will
vibrate more easily to provide a very
powerful bass range.
Autotuning function
Pressing the Autotuning button
causes the headphones to tune automatically to the frequency selected on
the transmitter.

A new way of listening.
You can see at first sight that these are special
headphones. The balance Series headphones have
indeed been designed for lounging on the sofa in
front of the TV.
Designed for couch potatoes, these wireless headphones are true stress-killers. Optimized for speech
reproduction and featuring volume and balance
controls, they make watching and listening to TV a
highly comfortable experience, particularly, if your
partner is less keen on listening to the sound of
your favorite program. Another convenient feature is
the automatic on/off switch: the headphones will
switch on automatically when you put them on and
off as you take them off.
The balance k 216 afc uses RF (radio)
transmission. An Autotuning button causes the
receiver to tune automatically to the transmitter
frequency. You can move about freely inside your
house or garden while listening, because the radio
signal penetrates walls and ceilings.
• Balance control for adjusting the left/right
volume ratio
• Optimized for speech intelligibility and
accurate music reproduction
• Automatic on/off switch on the speaker arm

Loud and soft are highly subjective terms ...
This is why TV often causes quarrels among friends
or within the family. What sounds soft to one person
may be too loud for the next. Of course, the volume
should be set so that everybody gets all the dialog
but turning the volume up does not necessarily
mean the dialog becomes any clearer and certainly
won’t create a pleasant, relaxed mood.
Optimized for speech reproduction and
providing a balance control for setting the left and
right volume levels as desired, the balance k 122 ir
allows you to relax when watching TV.
For added convenience, the headphones
will power up automatically as you put them on and
mute automatically as you take them off.
The balance k 122 ir uses infrared transmission that depends on a direct line of sight between the transmitter and receiver. Wherever you
can see the transmitter, you can move about as you
like and receive a clean signal.

Phones for every head.
Talking about headphones, you go for the very best.
So do we.
Although high quality components are a prerequisite
for any high quality product including headphones,
it takes more than that to make an excellent
product, right?
IVA processing
In the case of AKG, the difference is more than
55 years of experience and know-how, painstaking
attention to the smallest detail, and our constant
endeavors to create better products that lead to
future-oriented headphone technologies.
We do not follow short-lived trends, but strive to
develop true audio innovations. Countless awards
and more than 1,400 international patent
applications attest that this has been a good
strategy. The important thing for us is to make sure
you will be satisfied with our products and services
for many years.
Curious?
