Headphoneus Supremus
I just popped in the ED9s and listened to some classical music, using the dull brass filters. Wonderful! After months of using multi-driver IEMs it is remarkable how good the ED9 sounds with a micro DD. Soundstage is super and the tonality really natural and the transient response is quick and clean. If KZ revisited these with a detachable cable they'd be giant killers.
