Excerpt: I've spent a lot of time with good balanced armature monitors stuck in my ears. Mostly it's a pleasure --- there are some darn good headphones out there of this type: Jerry Harvey Audio JH13, Shure SE530, Etymotic ER4P, and Audéo PFE come to mind.
Summary: Sony MDR-EX600 Review
I borrowed a pair of these from Tyll for review. These are the MDR-EX600 which are commonly faked on ebay.
I must admit that the charts are actually quite impressive. They are very flat from 5Hz up to 1200Hz and have some nice peaks in the treble.
Pros: Sound Quality is awesome, cable design
Cons: Fit issues, standard tips are horrible, crack easily
Summary: Bass = perfect
Mids = perfect
Highs = perfect
The highs are very slightly rolled off. And I've watched a video review from Inner Fidelity which mentions grain, but I hear none. Also the EX1000 doesn't offer much more than the EX600, I cannot justify the price of that IEM.
Pros: lots of tips, neutral sound, decent price, comfort
Summary: Cowon J3 + EX600 with comply T500 tips A listening sesion of your favorite album with the Sony MDR EX600 feels like fe****io from Jessica Alba and eating chocolate icecream at the same time, all this while watching your favorite team winning the related worldcup and receiving an Oscar from Natalie...
Pros: Clear, bright, detachable cable, lots of eartips, tight punch bass, responds extremly well to EQ
Cons: might be too bright, case is useless for carrying it, fit might be awkward, bad or mediocre isolation.
