AKG expert panel

A while ago we invited all AKG Facebook fans to subscribe to our AKG reviewers program. We received more than 500 enthusiastic entries from people who wanted to be the first to test and review our headphones. We also approached some ‘authorities’ in this sector who tried and wrote about the K550. Check out below what some of them think. The AKG reviewers program will be soon continued and extended to more participants…so, stay tuned!

    The sound spectrum is excellent, the room feeling very well. You really have the feeling that the sound came from the vicinity of the ear, and not directly from a cannula which has set it in the ear canal. Who wants to buy a neat Dröhner head for the road-blocks and Quiet-game sessions, lies with the AKG 550 is not so far off. The sound is also convincing critical listeners in all situations.

    AKG has indeed produced a sealed headphone that sound very open. No doubt, it´s the best headphone I ever listened. Long listening sessions are comfortable to do. The build quality is good and the design is superb. This is a real beauty. Straight lines, fantastic materials and finishing. I higly recommend these headphones - they are a precise piece of engineering.

    AKG promised to develop a sound-insulated, well-balanced sound headphones. And they kept the promise: from the environment you do not get much more with really. The sound is full and round and not to stop blaring.

    I found them really convenient at home. My husband was able to watch football in peace while I was dancing with the spaghetti to the Foo Fighters. Even though I looked like Mickey Mouse , I had fun. For girls they are perhaps a little bit large. For men, however, a real eye-catcher ... or worth listening to? Anyway, the sound and the seal are great. Apart from the size, they feature a very minimalist design.

    Sweetly communicative, the K550s handle tempos in a natural manner and punch into and out of low frequencies with razor sharp precision

  • Nuts Magazine - November 2011

    These strike a balance between the noise isolation of closed-back cans and the spacious noise of open-backed ones. Beefy 50mm drivers add oomph!
