2" (50mm) driver real image engineering

A powerful, 2-inch (50-millimeter) driver enables the
AKG K551 reference-class headset to do things that
other headphones can only dream of. Music is rich
and layered, while audio environments seemingly un­fold before your eyes, with sound that’s undistorted
no matter how high you turn up the volume.

Imagine the amount of space between your ears
and your AKG K551 headphones. Now imagine the
amount of space in an actual soundstage. Real Im-

age Engineering is the science that ts the big space

inside the little one. With Real Image Engineering,
sounds are huge and accurate, with an incredibly
realistic sense of width, distance and depth.

You love your music. The person sitting next to
you doesn’t. Not a problem. AKG engineers have
optimized the K551 headphones for minimal sound
leakage so that your music is yours and yours alone
to enjoy anywhere you go.

in-line microphone

AKG K551 headphones have an in-line microphone
so that you can make calls that are every bit as crisp
and noise-free as the music you listen to on your
smartphone.

Trafc is loud. Subways are loud. Other people’s

phone calls are loud – and annoying. But you’ll never
know it, because AKG K551 headphones have such

a perfect t and effective sound insulation that all you

hear is the music you intended to hear.

Great music doesn’t go out of style, nor will these
headphones. The AKG K551 reference-class
headset is built to look sleek and sophisticated, with
a commanding yet minimalist design that is available
in either white or black and silver.

The AKG K551 reference-class headset keeps music
in and noise out. The closed-back design helps pre­vent outside noise from entering your ears while also
preventing the sounds you’re listening to from leaking
out for the outside world to hear.

2d-axiS fold-flat mechaniSm

Though we created the AKG K551 headphones
so that you would never want to take them off, we
admit that there are occasions where you may need
to use your ears for something other than pure aural

bliss. For those moments, the K551s’ 2D fold-at

mechanism makes storing and transporting your
headphones simple and worry-free.
