hi, i'm ne here this is my first post!i read and listened thousand reviews and today I'VE BUYED TODAY THE MK5 i want to start with them before the er2se.before i tried the ikko oh10 obsidian, too much synthetic sound caused by ba armature; i send back also the tri i13 pro (better than obsidian) too much bass (but nice, bassheads will love them) , nice mids (planar) but only at high volume , highs synthetic too....ba armature.i'm a musician and i do thinks that ba armature aren't my cup of tea for timbre accuracy. i'm a glad owner ow beyerdinamic t70p i love its dynamics definition and it is not for basshead. i search for the frequency response and it seems similar to the ety .... i let you know if'll appreciate the mk5. as a dongle i've got a questyle m12.. very strange product: with the ikko and tri sound awful ,mid too recessed and shrink, but with beyer dynamic t70p it's wonderful as it tame his splashing sound giving a sort of analogic sound never harsh but still informative at the highs and also spacious (or are the t70p spacious?). so i imagine that it will be good also with etymotic mk5 to give them a sort of v sound. goodnight
