there's absolutely no complaints on the IEM, it has a great sound and is very competitive with IEMS triple, even quadruple it's price.
however, the cable is leaving much to be desired. the thin cable doesn't bother me much, though it might to some. what i don't like is the "memory foam" earhooks, they just look tacky, and feel bad to use.
would still recommend the the set, especially at this price.
Phantastic fit, deep lows, good mids and highs, average soundstage
