Overview

Our take on the AKG K 550

Most headphones with a sealed earcup design let you hear your music better in noisy environments, like at a club or in a busy office. But they can also bottle up the sound, making it feel as though it's coming from inside your head. Not the AKG K 550s. These advanced closed-back headphones deliver the spacious, realistic soundstage of an open-back design, while providing blissful relief from the outside world. And because they're sealed, you can enjoy truly private listening without sound leaking outside to those around you.

Large drivers for outstanding performance

AKG has been making high-quality headphones for music enthusiasts and professionals for over 60 years, and that experience really shows in the K 550s. They use big 50mm drivers, the largest in the AKG headphone lineup, to crank out powerful, crystal-clear sound from your hi-fi system or virtually any portable player. No matter what type of music you listen to, these 'phones will give you sparkling highs, engaging mids, and dynamic bass.

The K 550 features a padded adjustable headband and ultra-soft around-the-ear earcups for a comfortable fit. The single-sided oxygen-free copper cable supports a clean signal from the source to your ears, and comes with a convertible headphone plug that works with both mini- and full-sized jacks. And its 2D-Axis earcup design folds flat for easier storage and transportation.


From our review of the AKG K 500 headphones

"The AKG K 550s are a good high-end headphone choice for less-than high-end listening situations. Although slightly warm, I felt I was getting all the musical detail my sound sources were delivering. And they were comfortable enough to wear all through the work day. And that's more than good enough for me!"

Private listening and great sound meet in the AKG K 550 headphones

Written by Woody Sherman, A/V Writer, on 4/2/2012 5:02:00 PM

Ever since I started working at Crutchfield I've been on the lookout for headphones that met a certain profile.

a) I work in a quiet area, so they can't leak sound. Otherwise I'd inflict my eclectic musical preferences on my co-workers. b) They should be comfortable for long-term listening. And c) they should have an extended, flat frequency response, with a slightly warm tilt.

I don't know how much looking you've done for headphones. Apparently, what I was looking for is a rare item. Sealed headphones are not known for uncolored sound or fantastically even response. But the AKG K550's are an entirely different animal.

I became curious about these gems after reading several strongly favorable reviews online from some respected headphone reviewers whose blogs I read regularly. I snagged myself a pair and checked them out. I haven't had them off much since. It took me about 5 minutes of listening to realize I had to buy a pair.

One word of caution: getting the right seal is important with these headphones. That's not hard to do on my big noggin, but if your head has more demure dimensions than mine, you'll need to work with the nicely designed adjustments on the earcups to make sure that you're surrounding the ears with no gaps to the outside world. Then you'll hear all the remarkable bass, smooth midrange, and nice extended treble you've been looking for. Plus, you'll appreciate the luxurious comfort. I really like these headphones. I'm pretty sure you will too.
