Being out of production for a few years, I had to hunt this pair down for a few months before I could get my hands on it. And boy was it amazing.
 
Everything sounds fantastic out of this set of IEMs, but put on a track with strings (violins, cello) and feel the hairs on your head tingle. Overall warm & bright signature. Instruments are vivid & accurate. Treble extension is amazing. 
 
Con is if you're a basshead you'll find these slightly disappointing. Also, there is a lack of aftermarket parts (the cable while detachable, is not easily replaceable as it's a custom made)
 
If you manage to see one of these lying around, please grab immediately (regardless of price) - it is worth it.
