AKG K701 Over-ear Headphone Review$539.95
Though the frequency response of the K701s is a bit more dynamic than we'd like to see, it does manage to stay within our ideal limits extremely well. It has a nice, even bass response, but it does seem to shift the mid tones a bit, emphasizing the 2-4kHz and 7-9kHz ranges. What does this mean for you? Well, in addition to making cymbal attack sounds slightly underemphasized in comparison to the rest of your music, the cymbal shimmer and fricative voice sounds will be marginally louder. Beyond the mid tones, the K701s manage to keep some of the high tones before a strange underemphasis at about 14 kHz.
The AKG K701s don't have much distortion, but it's there. Though you will find it quite inaudible, audiophiles will be quick to point out that it's not perfect.
We were a bit surprised to see that the AKG K701s had such an erratic tracking response, but all in all it's not as bad as it looks. Most of the shifts in channel preference are less than 2dB, which is nigh inaudible. It's not perfect, but it's far from the worst response we've seen from high-end headphones.
