Day two using the new pads. Yesterday I used them about 8 hours, today so far about 4 hours. I've been playing a mix of vocal/acoustic, alt rock, synth alt, and a little classical. The lower bass holds to be true, it's not as impactful. I've EQ'd in a bit, which does help. Still not quite as good as the lambskin. Everything sounds a tad more distant and less distinct as well. Not dramatic though, and still better than other closed cans I've heard. One aural benefit I detect is the stage sounds slightly bigger and more open, which makes sense. Since I come from a realm of open Sennheisers this suits me pretty well. The clamp pressure is definitely higher, but not too bad on my oversized sconce. The ear holes are small, so my ears tend to be bent slightly inside there, and they do get a fair bit hotter than the OEM pads. My ears feel noticeably hot when I remove the cans. Overall it's fixed the pressure issues without compromising the sound very much, so I'd call it a win. Still using just TP mod and no inserts.
On a different note I am having the problem with the sizing sliders moving over the course of a few days. Probably due to the size of my head, but if it gets worse I'll have to contact Dan about it. The carrying case has come in handy, although I'd recommend sewing in the velcro part of the netted "pouch" - my velcro is coming unstuck and falling off. Also I would suggest looking at moving this "pouch" toward the headphone cans themselves and away from the headband. You could then make the headband part much thinner and turn that into a handle. Carrying the carrying case is awkward, to put it mildly.
