I've searched head-fi and Googled them but can't find much on them.
Does anyone know anything about them?
Are they any good? Worth $200?
What kind of phones are they?
Check out my "review" http://www.head-fi.org/products/ess-mark-1-stereophones/reviews/9741, although I may not know what I am talking about, as I don't have any other headphones to compare them to, and I haven't listened to the Precide Ergo's in about 9-10 years, so I really can't compare. Maybe someday I'll borrow the Ergo's from my in-laws and do an AMT comparison.
