the ATH m50 are the best ive used.
I have 2 pairs of 280s and 1 pair of 215s, and a broken pair of 271s.. and a pair of Grados.
but the m50s are loads better in every respect.
when I have the money, I am going to retire the other cans and stock up on m50s
AH. forgot to mention, Mr. Harvey Gerst's creation..(Mr. Gerst is a legend!)
these../ MoreMe Studio Headphones
I had many pairs of those before having all my equipment "misplaced" by the Turkish House moving firm that was responsible for packing up my household goods for the trip from Germany back to NC...
Can't go wrong with any of them, but m50s and the More Me..those are my "must have" cans..at least for isolation/tracking..(outside of that I prefer akg 701s and Stax)
as a matter of fact, im going to buy a few pair of the MoreMes friday. Have a big job coming up..gonna need em.
