Cetainly not the best- but Ive listened through some really nice phones- my old "refererence" stand-bys are Koss pro 4a's. You have to look high and low but theyre around yet. Many times NOS on some guys shelf. 20-20,000 response if I remember correctly. Im sure a bunch of folks are gonna pile on me for saying this but those things are tougher than nails and have a "warm" sound to them. Just my opinion. In fact, Im sure they are still marketed by Radio Shack. Might say "Optimus" on them as well....
