Famous AKG sound quality
For over 65 years, AKG Acoustics has been the leader in creating studio sound in headphones. We hold over 1,400 patents for our groundbreaking products, plus two technical GRAMMY Awards (in 2010 and 2005) for sound innovation.
1-31/32" (50mm) drivers
Powerful 1-31/32-inch (50-millimeter) drivers enable AKG K551 reference-class headphones to do things that other headphones can only imagine. Music is rich and layered, while sound environments seemingly unfold before you no matter how loud you turn up the volume.
Real Image Engineering
Real Image Engineering is the science that fits an actual soundstage inside the space between your ears and the AKG K551 headphones. With Real Image Engineering, sounds are huge and accurate, with an incredibly realistic sense of width, distance and depth.
Outstanding passive noise reduction
Traffic is loud. Subways are loud. Other people’s phone calls are loud – and annoying. But you may never know it, because AKG K551 headphones offer effective sound insulation. Premium foam ear pads wrapped in soft leather help create an acoustic seal, so all you hear is the music you love.
The AKG K551 reference-class headset keeps music in and noise out. Its closed-back design helps prevent outside noise from entering your ears and minimizes sound leakage. So your music is yours and yours alone to enjoy anywhere you go.
In-line microphone and remote control
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 iPhone. The mic is ideal for FaceTime and Skype applications, and virtually any app requiring a microphone. The headphones’ three-button remote lets you control the playback functions and volume from iPhone and iPad devices, as well as Apple laptops and desktop computers.
Great music doesn’t go out of style, and neither will the AKG K551. These reference-class headphones are sleek and sophisticated, with a commanding yet minimalist design that is available in either white or black and silver.
2D-axis fold-flat mechanism
Though you may never want to, you will take your AKG K551 headphones off at some point. When you do, the AKG K551 folds flat for simple, worry-free storing and transporting. High-quality, metal-alloy material keeps the folding mechanism strong and durable.

Enter AKG. They design headphones with seemingly no effort to artificially add bass or warmth but instead strive to create transparent, clear sound.
And everyone bashes them for it.
I have read endless complaints about how "bright" they are and "lacking in bass". These things just sound accurate and realistic. I think people have almost forgotten what that sounds like and--in the bizzzarro world we live in--AKG's true to life sound is what people's ears perceive as "weird". It's like The Matrix! But.....different.
I say forget it. These sound drop dead amazing and all the others sound dull and lifeless (to me) by comparison.
Just don't listen to mp3's with these babies. That might hurt. I listen to CD's ripped as WAV files on my iPod and I couldn't be happier.
But these are not power headphones and if you confuse oomph! to the gut with quality you may not like these. The headset has large magnets in the speakers but this is to provide clarity, not to strip your ears of cartilage.
I do think that there is a legitimate complaint with power. There is a way to make the sound a bit more amplified without reducing the detail and delicacy of the sound. How? An external amplifier. This is easy at home if you have a home stereo system. Just crank the power a bit. But if you are walking about you should probably resort to a headphone amp. It can make a dramatic difference both in increasing the overall volume while boosting the bass by a great deal. I would recommend the FiiO E12 Mont Blanc Portable Headphone Amplifier. These two products combined produce a powerful sound with extraordinary detail and clarity. If you are looking for some great headphones, it will be tough to beat these.
If these are within or close to your budget, I highly recommend them. They're truly state-of-the-art in every respect. Love 'em!!!
The one downside is that the mic doesn't work with Android phones and the cable is a touch short.
They are larger than you probably think they are, but are extremely comfortable to wear for long periods. Don't expect a ton of noise isolation, though there is some.
However, I do not recommend this headphone for users, who love bass and exciting (even if the sound is faked) sound. K551 gives you FLAT sound, the original sound the music provides.
This can be boring to some users. I found its sound boring, so decided to return it. Nonetheless, it is truly a great reference closed headphone...
