Best headphones?

I have definitely heard better than the Sony's. One of my co-workers had the old stax electro-static-on-your-ear headphones with the dedicated amp. Those were the best sounding I have heard (at $2000 in 1993 they should be!) I once heard some of the sennheiser midrange ($125ish) and I thought they were very detailed and airy sounding. I like the Sony's better because of their relatively small size. Has anybody out there heard the sony nc-20 noise cancelling models ? ( the msrp 200 one )

Right on with the comments John on the Sony MDR-V6. I have a pair and Like them alot. I compared with my brothers Sony 705s with the blue label on earpiece (not sure of the model #?) and the V-6s were a lot smoother on the high end (705s sounded less clear and artificial on the high end)I'm sure theres better out there but these sony's are great!

I've heard no other speaker or headphone that is as accurate as the current Stax Omega 2-007. If listening to classical or any accoustical instruments, voices on vinyl this is the way to go. I've heard most stax phones fed by Clearaudio/Ref Gold, and this version is in a different league. That is, if money is not a question, at $5K for headphone plus a used SRM-1T

You're making my bank account boil and my aural sensibilities ache with longing, Baldridge! If you'd let me borrow this Stax headphone, I promise to clean my ears with bleach before putting them on! I want some soooo bad! Someday....

The Stax win hands down, but I just purchased the HD-600 because I wanted a pair that could plug into a regular headphone jack without special power supplied etc. If you are purchasing headphones to be your main "speakers" go with STAX, if you are purchasing headphones to augment a good set of speakers go with the Sennheisers
