They leak loads of sound but so do the HD555s and D2000s!
The D2000s don't leak ntan wurt though. I mean, yeah they do leak, but overall they're not bad at all and if, just for instance, you listened to music fairly loudly in, say, a library, unless someone was sitting at the same table, I doubt anyone would really ask you to turn them down or something (well, not that I've tested this very thoroughly, but I did try to test the sound leakage levels a bit by putting them on something that fully covered the insides like a real head would do and I couldn't help but to think that the actual level leaking wasn't half bad at all.) Really, though, I'm convinced that that little "vent" is part of why they sound so good really. It gives them a sort of "bass reflex" type of thing which is probably part of how they manage to do the bass so well and I suspect maybe helps contribute towards their surprisingly good soundstage for a seemingly "closed" cup headphone, so IMO their sound leakage is a plus. d-:
Great sound stage, nice bass, the only thing is that the treble is a small bit harsh. But they seem to be getting better with every hour of burn in.
It never goes completely away though I guess. I love my D2000s, but in the end I guess my ears are just a bit more sensitive towards the frequency ranges right where the D2000s peak or something because at times they just sound almost outright painful to me with just a very rare few songs. I found that the soundstage mod in particular made it worse and ultimately had to give up and pull the little plastic cup pieces out of the cushions. That made it a little bit better for me and if you're running stock obviously you'd never have that particular issue, but for me even without that the highs can be a tad rough on me at times.
Actually, I truly hate to say it, but I'm seriously considering giving up and selling my MarkL-modded D2000s. I recently got some Sennheiser HD555s, modded them into HD595s (eg pulled out the "surround reflector" foam pieces -- it truly is quite messed up that, sonically, the only real difference between the $350 and the $150 sets is that they actually ADD something to the cheaper set) and then did the soundstage mod and now I'm finding that I'd rather listen with my HD555s as blasphemous as that might sound. I guess I kind of like the Sennheiser sound better (at the risk of being chased out of here with stones, lol.) How much does a used but modded pair sell for these days anyway (the mod has to be worth somewhat on its own, right?) I'm trying to convince myself to sell them, but I have to admit, I do love them. (What I really wish I could do is find a family member who would buy them. Then at least they'd stay in the family, lol. I'm the only one in my family who even knows what a headphone amp is though, much less ever spent anything serious on sound equipment -- unless you count some absolutely horrid sounding Bluetooth headphones my mother once got that make me want to gouge my ears out...) How does anyone part with these once they have them? Lol. But it's just sad having them sitting there gathering dust -- especially given that I could use the money. (But then, it probably wouldn't last all that terribly long anyway. My credit card bills alone are killing me. That's the worst part. Even if I gave up and sold them, it probably wouldn't go towards anything nicer than catching up a bit more on everything. That makes it all the harder to give them up even though I probably should...)
