I have a pair of MDR-NC33's but have read that it could possibly be the same as the NC22s, 85 & 90s just w/ different porting/tuning that gives the slight differences in frequency ranges.

Just as an FYI, I removed the WAX filter on my NC33s (which I was going to give away), and they have became completely different and better cans...

I also am using t400's with them, and have added more passive isolation... I'm very impressed with these NC33s now.

but curious, what else might have the same drivers...
