My big ears reflect a lot of treble, so the Q701's treble forwardness sounds pretty natural to me. Hmm..do you think the 8khz recession is part of what makes the X2 sound more natural?
I think that the overall fuller sound makes them more natural sounding .
Don't get me wrong , I really like the Q's but to me the the X2's are superior.
I also disagree with a lot of users here that lack of bass equals neutral (or natural) sound. I'm definitely not a basshead but I find bass to be a natural part of the frequency spectra just in the same way as the other parts. A lot of users here seem to think differently. Ymmv
