Well in the 90's there was nothing like the ER4S around anywhere. One of two thing in my entire life I bought blind. Based on a review in UHF I did not particularly value their opinion but was more interested in the isolation. I was on a flight every Monday and needed something to get me through and they fit the bill perfectly. Quite frankly at the time they were a godsend.
