Denon AH-D7000 Over-ear Headphone Review$999.99
Because these cans are designed more for listeners of music, rather than the studio mixer in mind, the frequency response is naturally going to look a little bit different than just a flat line. For example, the Denon AH-D7000s stay within our ideal limits for a good range of frequencies, but they do boost some of the higher frequencies to emphasize cymbal shimmer a bit, and de-emphasize sibilants in speech.
There was a little bit of distortion from the Denon AH-D7000s, but nothing that would be noticeable to anybody listening. Audiophiles will be quick to point out that it isn't distortion-free, however, but unless you're a robot with high-sensitivity microphone ears, you will not be able to hear it.
This result was a little baffling, to say the least. Typically, we see high-end headphones give us a very even tracking response, but the Denon AH-D7000s did not. The shifts in channel preference weren't terribly egregious, but the higher the frequencies went, the more error they seemed to reveal. Changes are good that you won't be able to hear these errors right away, but if you know what you're looking for, they may be audible.
