In the summer of 2002, nearly one

billion people were listening to AKG.

Maybe you were one of them. Re­

member the opening ceremony of

the soccer world cup in Seoul? The

sound system there used the latest

wireless technology from AKG.

One reason was that AKG is one of

the world's leading manufacturers

of headphones and microphones

plus AKG audio equipment has

been in use in countless concert

halls, conference rooms, broadcast

and recording studios, theaters,

and rock concert venues all over the

world.

A lot of mobile phones and a grow­

ing number of cars including the

new Maybach ultra-luxury sedan

f rom DaimlerChrysler use AKG

technology.

So, whether you own a Maybach or

not, treat your ears to tailor-made

AKG sound and experience the

finest reproduction available.

P h o n e s f o r e v e r y h e a d .

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?

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-l ived 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?

Why don't you try our headphones and compare them against other models. I am sure you will find that AKG headphones do not just re­produce audio but make you e n j o y what you hear. That's the differ­ence.

Welcome to digital Cloud 9.

The hearo 888digital is a digital surround personal listening sys­tem with the kind of wireless headphones that high-end enthusi­asts have been wait ing for. Digital radio transmission and d/g/te/anfennad/Vers/fy circuitry afford virtually noise and dropout-free reception. Incredible as it may seem, the h e a r o 888 d i g i t a l actually provides the same audio quality as comparable hardwired headphones.

Patented IVA processing makes the headphone sound seem to come from loudspeakers, while the integrated Dolby Surround Pro-Logic and LOGIC7 surround decoders add surround sound signals.

So, if you are looking for headphones that are equally good at dramatic movie sound effects, crystal-clear dialog, accurate music reproduction as well as the most delicate violin sound, the quietest piano notes, or the most ethereal guitar overtones, then the Hearo 888 digital is the best choice for your discriminating ears.

hearo player VSS

Windows users love it: The Windows Media® Player is an impor­tant tool for playing back music or video programming on the PC. You can now make this program even more powerful, simply by downloading a plug-in from AKG that provides 3 - D sound through conventional headphones without expensive peripherals or com­plicated modifications. The secret behind this miracle are two technologies that are also used in the famous wireless surround headphone systems of the HEARO Family. IVA processing developed by AKG provides a sound that does not play inside the head as it would with normal headphone reproduction, but actually seems to come from loud­speakers placed in your listening room. The LOGIC7 decoder automatically identifies the input signal for­mat, monitors it constantly, and simulates up to eight loud­speakers distributed around the room. It generates the 3 - D sound from almost every input signal format from stereo to the latest surround standard. To avoid overburdening your PC with its need for processing power, the IVA surround processing level can be adjusted auto­matically or manually. Selectable presets such as MOVIE and JAZZ provide typical timbres for a more realistic sound.

The Hearo Player is a real bargain for those who are looking for a way to enjoy surround sound from their PC at home or notebook computer when traveling but do not want to invest in extra hard­ware or throw away their favorite headphones.

Self-adjust ing headband The headband auto­matical ly 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.

3 in 1 The transmitter serves as a storage cradle and battery charger for the headphones (except k 105 uhf). As soon as you place the headphones on the transmitter cradle, battery re-charging starts automatically.

-> High-capacity rechargeable batteries The supplied batteries have a long life, with no risk of overcharging and mini­mum memory effect.

-» Speech-opt imized 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.

-> 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 opt i­mally balanced sound

-» Auto- tuning funct ion Pressing the Auto- tun ing but ton causes the headphones to tune auto­matically to the frequency selected on the transmitter.

-» Patented AKG Varimotion diaphragm The diaphragm is the most important part of ^ ~:-/^"""N,-^1-» the speaker capsule. An K ! L* __' ideal diaphragm should combine high compliance around the perimeter with a piston-like motion in the center. The patented Varimotion d i ­aphragm 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.

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.

Sounds familiar?

The reasons are simple. Everybody perceives sound differently, and your left ear may be more sensitive than your right ear. This means that sometimes it would be better if the sound were a little louder at one ear than it is at the other. Another reason is that most headphones are de­signed for music reproduction. If you just turn up the volume of your TV set, the ambient sounds and music become louder too so you won't hear the actors' voices any better.

The comfortable TV headphones from AKG have been optimized for speech reproduction and al­low you to adjust the left/right volume ratio. They bring a new level of fun to TV watching.

TV WIRELESS

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 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.

The balance k216 afe uses RF (radio) transmission. An Auto-tun­

ing 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.

-> Replaceable ear pads are made of breathing, skin-compatible mate­rial and easy to clean.

-> Patented AKG Varimotion diaphragm The diaphragm is the most important part of the speaker capsule. Acoustic scientists require this extremely thin piece of foil to perform the most spec­tacular feats.

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. Being thin­ner around the rim, the so-called move­ment zone, the diaphragm will vibrate more easily to provide a very powerful bass range.

The audiophi le-grade k 501 uses a thicker 80-um foil with even more sta­ble vibration performance. The d i ­aphragms on the k 501 are hand-se­lected and feature trapezoidal corrugations that further enhance their excellent acoustic performance.

Looking for cost-efficient headphones for many different applications? Look no fur­ther. The I c 4 4 \ s a true all-round performer with solid bass and clean highs at a value price.

Some styles of music wouldn't work with­out a solid, low-down, gutsy bass range. That's exactly what the large 1,6-in. (40-mm) "Turbo-bass" speakers of the k55 de­liver, along with accurate highs.

Reviewers have called the k 66 a best buy. Their clear sound provides great listening fun at an incredibly low price.

If you think that the development of stereo headphones has reached

its ceiling, the AKG k501 will make you change your mind. The

undisputed flagship of our reference class and many reviewers'

favorite delivers a spacious, airy sound at the high frequencies,

which has earned it an excellent reputation among lovers of

classical music. Al though the physical difference is minimal, it

makes an enor-mous difference for sound purists. The diaphragm

is 80 urn thick in its central area for enhanced clarity at high

frequencies and thinner around its perimeter for solid, accurate bass

response. To further improve the sound, the hand-selected

diaphragms are reinforced with trapezoidal corrugations.

HI-FI HIGH-END

klOOO

The only thing the k iOOOhave in common with conventional head­phones is that you wear them on your head. They are the reward for the many years AKG engineers spent searching for the ulti­mate natural, spacious sound. The k 1000 is a totally open design. Small leather pads hold the speakers a small distance away from the ears, creating a defined acoustic space. This is the visible aspect of the design that creates the same nat­ural, binaural perception of sound as a pair of stereo loudspeak­

ers would. On the inside, too, the fc 1000 are totally different from any other kind of headphones. Driven by dedicated VLD magnet systems, minimum-friction multi-layer diaphragms provide plane-wave sound fields in front of the ears. The sound field is subjected only to the changes and reflections caused by the anatomy of the user's outer ears. This is the most natural way of headphone lis­tening. Small wonder that the k 1000 were chosen "Headphones of the Year" more than once.
