The latest addition to the collection.
Straight out of the AKG house sound with expansive midrange, precise treble and bass detail as opposed to bass oomph. If anything there is not as much bass as I was expecting since they are closed backed, but I like that and they do do bass depth when it is emphasised in the original recording. The soundstage is not great. The drivers are closer to your your ears than on the K702. My flat ears still slightly touch the inner pad on the K271s. That was irritating at first, but now I do not notice it.
They isolate from outside noise very well indeed, when music is playing. In silences you can still hear what is going on around you. They have the super feature of muting automatically when you take them off.
They do leak sound, such that you could not use them at volume in a quiet room sitting next to someone who is easily distracted. The most leakless headphones I have are still the small portable Sennheiser PX200s, but they cannot do listenable higher volumes like the K271s can.
Very. They adjust to your head automatically, are very light, have big pads and you can chose between felt and leatherette. I would use the leatherette if it was a recording studio and lots of people share the headphones as you can give them a wipe. Otherwise the felt is lovely and soft and your ears stay cool. I also really like the detachable lead and choice of straight and curled.
I got them for £99 (including delivery) off ebay. With the two sets of pads and two leads, the mute feature and their size and build quality they are good value at that price. But, the baby of the AKG range, the K44, which can be had for as little as £19 have 90% of the sound, are closed backed and only leak a tiny amount less sound and with the leatherette pads are just as light and comfortable. Diminishing returns mean the K271 is really for the audiophile who wants that last amount of detail, but the K44 are still very worthy of consideration.
