These are comfy, sexy headphones. How do they sound to me?
Uneven.
They're choc full of bass...and lower midrange. Mid to treble transition sounds fairly v-shaped. The sibilance these things produce is inescapable, unnatural. Cymbals lack body, they just kind of...hiss and ring. I noticed faults a little less while listening to classical and jazz, but once electric guitars and vocals kick in in rock and pop it's pretty obvious where these things could use some tweaking.
Comparing them to other closed cans reveal stark differences to me. Audioquest NightOwl Carbon is much more neutral and natural sounding, though still a bit v-shaped in the mid-treble transition. B&W P7 is more natural sounding with less bass emphasis and a better bass-mid transition. These are more open and natural sounding between 1-7khz than the Z1R. Sibilance isn't as piercing as the Sony. These are slightly shouty though, soundstage isn't great. B&W P9 has similar boosted bass and lower mids, possibly these are a bit boomier. Kinda mushy sounding to me compared to the Z1R, but they don't have the sibilance javelin of death.
Ultimately I think the NightOwl Carbon beats these handily at every turn, and they are pretty comfy. There is less coloration inbetween the recording and your ears with them. The Z1R isn't at all neutral or natural sounding, but I guess not everyone is looking for that.
