I'll have to do another back to back, but for the money nothing touches my mediadevil artisanphonics.
I have quite a few iems including the eph-100 and i still find myself using the above phones all the time.
Open, spatial and with quite a punch and low end rumble to the bass.
They work so well with all kinds of music, but edm is where they really shine.
Well you get srs, Dolby, beats and other modes but I mostly use the eq.There's no clarity mode or anything of the like, I'll have a nose later on perhaps the audio mod is an addition.As for arhd it's like an improved stock rom. If like me you like to fiddle than you'll love viper.
I've moved on since then. I'm running the whole viper rom and loving it even more.You get a full eq and quite a few other tweaks to play with along with sense 6. But obviously if you're happy i too would be wary about changing things. http://forum.xda-developers.com/showthread.php?t=2334294
Have a look at the mediadevil artisanphonics, i have the ehp100's and think you'll be very surprised by them. http://www.amazon.co.uk/MediaDevil-Artisanphonics-premium-earphones-microphone/dp/B00GAIP5CO/ref=cm_cr_pr_product_top
Got myself bit of a dark horse in the form of mediadevil artisanphonics.
The rest of my collection hasn't had a listen since I've had this pair.
They continue to impress me with their punchy bass and sparkly highs, mids are slightly veiled but come out lovely with burn in.
For the money they're a steal, I'm starting to feel let down with my im50's, after listening to these.
I have the VSD1's and they're nice, but for me the above phone knocks spots of them.
Good bass nice and punchy, slightly veiled mids but come through with burn in and sparkly highs.
I love em.
