For listening, we used a system equipped with an E-MU 1820 professional sound card. We chose this unit not only for its quality, but also because it has a headphone jack with a hardware adjustment, so it is capable of providing a high level with no faults in the signal. This card also has a sophisticated virtual mixing board with inserts for numerous parametric equalization filters. We use this during listening to correct the response - in general, as a function of the response curves we record - in order to see how the earphones perform if we apply suitable corrections.
Finally, we also used a small Creative MP3 player to check how the phones behave with a lightweight device, in terms of the volume level that can be achieved without distortion, and any potential problems.

Hi .. here is a belated 2007 comment on the Sennheiser PX 200. It arrives now as I just received a non-returnable pair for Xmas to use with my iPod Touch.
I have never used headphones much.. but .. your review seems to me to be dead on. I know that there are better phones (e.g. the Grado SR 60/80 at al). However, as I "check the sliders" on the iPod EQ -- they seem to fill the mid-range hole that you have reported.
On close, they are pretty good -- but their closed design just cuts the kind of live ambience that you can get with a non-closed design like the Grado's.
The bass PUNCHES too -- just listen to The Eagles - Hotel California.
