To select the K551 and K550 were what the inner life and the bracket structure is substantially identical but are in cable length and included accessories and differ in price, so the K550 has a much longer cable and is supplied with a screw adapter from 3.5 to shipped 6.3 mm, while the more expensive K551 comes with a much shorter cable and not a bolt-from 3.5 to 6.3 mm but for a 3-button control for iPhone / iPod / iPad Features with integrated hands-free microphone in Cable features. Since I do not own Apple products Währe actually fallen to the K550 the election. However, the AKG K551 was to be had for next to nothing, so that I do not otherwise konte to order as the K551 at a Christmas flash deal on Amazon.
As for the sound as the K551 has not been rehearsed in a real state power, after I had recorded about him after 50 hours it can regard the sound of the K 271 MK II (and this is after all a headset Studio class) quite hold a candle. So the sound is overall very balanced and sound crystal clear, the highs are reproduced cleanly and without distortion, the bass is powerful and fun to play, but are never intrusive. No matter whether at the domestic system of Marantz or the MP3 player from Sony or Samsung Tab, no matter whether brutal Deathmetalgeschredder of Debauchery, a Gittarrensolo of Angus or Malcom Younng, a piano concerto by Yiruma or wüstestem Hardbase, pure sound technical know the K551 always convincing.
Of course some fineness is 271 MK II displayed not as accurate as in a studio headphones as the K, note that only high-quality vinyl recordings is somehow bad for today's digitaliesierten recordings on CD, DVD or Blue-Ray has no effect, and so many poorer mp3 file quite beneficial.
As for the possible volume, so these are both on the hi-fi system as well as to mobile devices beyond what one would expect his ears, and I hear as I said very much like very loud music.
The Einnstellmöglichkeiten the bracket are broadly diversified at the same time very finely divided, so that someone can easily find the optimum setting for each head size. The ear pads and headband cushions laid leatherette and relatively but not uncomfortable, even after several hours of musical enjoyment I had no pressure pain. As for the comfort is the K551 so standards. This is particularly noteworthy in the light of that it is a closed headphone while K551.
As just mentioned, it is at K551 to a closed circumaural headphones, thus neither noise nor outwards should penetrate from the outside inwards. Also in terms of sound insulation kannn the K551 provide the full range. If anything then penetrate only with very loud music minimal noise from the headphones to the outside, but also in the opposite direction of the K551 works perfectly whether imm flyer or in the morning during rush hour in the train, it penetrate no annoying or disturbing ambient noise through the headphones and dim so the music enjoyment.
However, there are also a few negative Kritipunkte, so the cable with not even 1.2 meters in length is a bit tight even for mobile use, but definitely for use on the domestic investment more than inappropriate. This is all the more negative since the AKG K551 explicitly advertises as headphones for home and travel to the weight. For home I have created with a headphone extension cable of Oehlbach remedy.
Another criticism is that the headphone cable permanently installed and is not interchangeable, which is an absolute no-go for a pair of headphones in this price range, especially if it is a pair of headphones is what also designed for mobile use, a cable breakage or tearing So well be in the realm of possibility.
Equally annoying is that the K551 does have a Faltmechanismuss and thus can more or less be stored in a space-saving, AKG but neither cajoling nor move for money this is an appropriate and especially suitable retention Case to deliver what the K551 disqualified as mobile and travel headphones. Who grabs the K551 simply defenseless in backpack, bag or suitcase should not all too long have joy in him.
CONCLUSION:
As for the main points of sound and comfort, but also in sound insulation sets the benchmark and would AKG really 5 star more than deserved, he zumahl hinbekommt the Spaghat and both high end devices as well as mobile to convince with superior sound white. As for the cable which not only far too short but to make matters worse, not even is also interchangeable, AKG should urgently improve after, just in terms of lack of transport bag. So there are then a whole but only 4 star, and yet a full purchase recommendation for all who are looking for a pair of headphones, the sound technical and sets standards both at home and is also suitable for mobile use.
All who want to use the headphones to the domestic system, but I recommend to choose the K550, which although not Apple has control but the cable in length to but facilities and sofa-compatible pure.
