I've been listening to these all day and continue to be very impressed. I have no problem recommending the Rastapants T50RPs over most of the mid-fi headphones in most circumstances. They're that good. They're not the kind of headphones that will "wow" the uninitiated with gobs of bass, or a huge soundstage, or a forward treble that pops out at you. But the more you sink into these headphones, and let its sound signature invade your brain, you'll realize that everything just sounds right.
I'd like to tinker some more with the bass port/vent, and different felt material, but I like these so much right now I don't feel the need to open these.

With the T50 mod I hear really deep into the music. I can hear discrete voices that once were blended into a more diffuse and blended vocal "sound." For example listening to Born on Punches or Houses in Motion on the fabulous 24/96 remaster of Remain in Light from HDTracks. Every detail of Brian Eno's and David Byrne's stunning backing vocals stands out in bass-relief. Localization is precise, and the interplay of the harmonies, which often sound like just 1-2 voices, creates a richly textured interplay that creates a radically different experience to the music.
+1 to this as well. This is only the second orthos I've heard, but these drivers live and thrive in the midrange.

Thanks for the tip. I don't hear much resonance, as the chassis seems very tight, but more Dynamat can't hurt. I'll try to add more next time I open these cups up.

Not much secret. I just took an exacto knife, and peeled a corner of it until there was enough to grab with my fingers. Then I pulled slow and gently. I got the newest batch of these, so maybe the glue on this batch isn't quite as strong as the older ones.
