a dream of sound
The world listens to AKG.
Hi-fi
TV/Home Theater
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
from 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.

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 future­oriented 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?
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 enjoy what you hear. That’s the differ­ence.
Dr. Hugo Lenhard-Backhaus
CEO, AKG Acoustics GmbH, Vienna
AKG history
“Pioneering spirit” best characterizes the ambitious work of AKG founders Dr. Rudolf Görike and Ing. Ernst Pless. After the war, people went to the movies seeking distraction from the stress of post-war life, so Rudolf Görike built movie projectors and loudspeakers, while Ernst Pless used his rucksack and bicycle to deliver the goods to constantly growing numbers of customers. Their very first customer was unable to pay in cash so he settled the bill in food, fresh from the black market.
When AKG was established in 1947, the company headquarters were located in a basement in the suburbs of Vienna. Before long, many AKG microphones
were in use, mainly at radio stations, in the­aters, on small stages, and at jazz clubs.
In the early 1950s, the two founders of AKG made their business breakthrough with completely new technologies. The micro-
phones of that era had a strangely shrill and hollow sound, and AKG technology added warmth and fullness to microphone’s sound.
In 1953, the first AKG dynamic microphone in the world became an interna­tional success, and the first large-diaphragm condenser microphone with re­motely selectable polar patterns set new standards for professional micro­phones. Almost every major radio or recording studio including BBC London, one of the first buyers, used these microphones.
The following years saw numerous new developments. Many innovations of that period are still in use today. The K 10 headphones used by the European Parliament are but one example. AKG research engineers have always loved exotic challenges. One of those was a real-life test of hydrophones for the Austrian deep-sea scientist Hans
Hass and AKG designers were happy to
spend days swimming and diving at the “Di-
ana Bad” indoor pool in downtown Vienna
that was very popular in those days. The
AKG team also fulfilled the very special
wishes of Herbert von Karajan. They had to
hide all the microphones at the first post­war Salzburg Festival because the maestro had decreed that the audio equip­ment must be totally invisible to the audience.
The company expanded and patents were applied for in rapid succession. AKG supplied microphones to major tape recorder manufacturers including Philips, Grundig, Uher, Loewe and others. Portable reverberation units created a new market in the 1960s and 1970s. Telephone transducers soon became a rapidly growing product line. This period also saw the advent of digital tech­nology and AKG made its successful “digital debut” at the 1980 Olympic Games in Moscow.
As early as 1974, AKG built the first wireless headphones. At that time, con­sumers were skeptical and many felt the new technology was too complicated. In the late 1980s, AKG launched the K 1000 headphones that were a dramatic improvement over all earlier attempts at creating a natural, binaural headphone sound. The audio community was full of praise. The new results of psychoa­coustic research were presented in exhibitions at the Deutsches Museum in Munich, the Kunst Museum of Bonn, and even used by the “Audimir” space flight project. The crew on board the “MIR” performed several tests to exam­ine the meaning of sound source localization for the humans in space.
The new AKG wireless microphone systems launched in 1996 used a new, revolutionary technology that was widely acclaimed in the marketplace. Big name pop artists such as Rod Steward, Peter Gabriel, and Simply Red used the systems on their tours and AKG became the preferred brand for many other famous musicians.
At the turn of the millennium, AKG engineers came up with the latest genera­tion of the HEARO Family, a new line of wireless headphone systems using the latest surround technology.
