Can I start out just by saying LMAO? My laptop's sound card is a sad joke. HP claimed that the laptop I bought a few years ago is an "Entertainment PC." It barely plays games (even all those years ago), the screen is tinted a slight yellow and thus misrepresents colors when watching movies and doing other graphical applications, and is I've just discovered today, can barely power headphones. The sound card in my new desktop allows for driver level equalization, so I don't have to bother with WMP.
It'll be a while before I rewrite that impression for the SRH440, as my opinion of them has drastically changed. I may sound overly enthusiastic, but I mean it's like I have a completely different pair of headphones. Without going into detail, the climax of "Passion," the orchestral version, sounds EXACTLY like I always wanted it to. What more can I ask than that from headphones. I'll mess around some more with the XB700 to see if it can match the SRH440. But the bass, it is definitely there now.
