As far as I understand, you're supposed to adjust those Comfort Zone controls while you're wearing the headphones, rather than setting them beforehand; they're spring-loaded, so they return to default when you take the headphone off the head. You would certainly be in a better position to test that than me.
As far as suggestions go, I don't think the length issue is necessarily a problem. There's a lot of information to go through, and I can't imagine really shortening it down too much. I would recommend doing something about the output level, though, since I had to turn the volume all the way up to maximum to make out what you were saying. Ironically, I almost never watch YouTube videos while using headphones (way too many horrible, fatiguing cheapo mics in use out there), so maybe it's not as bad while using headphones.
I enjoyed the impressions, at any rate. They were pretty much in line with what I've heard from others. That $25 price is mighty tempting. I really could use a beater for general purpose use, and something with relaxed treble should work well for all the shouty, shrill recordings on YouTube. Plus, there's this nagging feeling that I can't quite claim to be a true Head-Fi'er unless I've at least heard a pair of these things.
