I promised more over-enthusiastic ravings about the HD520 when my earpads arrive, and they arrived!
I've only been listening with the new pads for about 40 minutes, flipping through tracks and genres, and I'm having a very tough time finding something I don't like about what I'm hearing.
This is of course compared to my usual diet of HE-500, Momentum, DT-990, T20RP MKII etc...
Subjectively, the upper mids are a tad forward, and the bass rolls off a touch too early, but that's not to say it's weak or ins't there.
Objectively... these are pretty damn great.
These sound really awesome at lower volumes. (and that's not a joke about how the less you hear it the better you feel ^_^ but that they don't choke with less input)
I think there might be some distortion going on with busy tracks or bass-heavy mixes... but it's almost negligible.
There is also a slight lack of resolution and texture overall, especially in the bass, and there isn't enough percussive impact and dynamics to compete with high end modern headphones.
Easily better than any vintage K240 variant overall. Soundstage and sense of air are very musical.
I am going to keep two big eyes out for all of it's siblings.
I think these are the lightest, most comfortable headphones I've ever owned, and will easily rival my vintage DT990 and T20RP for head-time.
