I listen primarily to electronic, classical, and some other odd songs, and I would confidently say the HD25's are the safest pair of headphones you can buy on the market. They're apparently very versatile and sound good with just about anything. But they're very punchy to me, and the highs really bother me after a while. Also, the bass can sometimes be unfulfilling if I'm not sitting in a quiet room. I'm mainly oriented towards good bass, or at least immersion in listening, and the lack of soundstage and reinforcing bass have always been an evident flaw in these. I run them through an Audio 2 DJ soundcard and an NAD amp, the latter being very nice to listen through, and the former being very rocking, but still there's a presence of grandeur that I would like to see. Of course, I'm asking for things I won't receive. The HD25's are absolutely wonderful headphones all around, and are used as such, seeing as how they're presently the empirical DJ headphones. I do DJ with them, and I can testify. Lots of other big names can, too.
Recently I ordered a pair of AKG K240's to try to remedy this, which I will run through an NAD amp and EQ to my liking. I have yet to use them, but I was drawn in primarily by their neutrality and the fact that they seem to be good for drums. The HD25's are really rocking, I love listening with them, and I wouldn't trade them for anything, but they have their flaws. I would like to see a greater Mid presence. The emphatic highs are good for DJing, because dance music is commonly beatmatched on the backbeat.
I recommend them to anyone. I don't think anyone will be disappointed, and I certainly wasn't, but there were particular aspects I sought that I just didn't find. There's simply a breakdown of energy somewhere in these headphones, and I can't tell you where it may be, maybe in the favor of higher frequencies. And that just doesn't exactly work for me. But please consider this to be a personal review.
