I'm looking to try my first pair of KZ, the cheaper the better really. I'm leaning toward the R3's as I've not tried any wood based earphones as of yet.
Signature wise I'm a big fan of the Superlux EVOs and 668B, I'm really enjoying the VSD3s and love the signature of the Havii B3 Pro MK1, just a shame about the fit being a PITA!
IMHO ....get KZ EDSE , Micro Ring and ANV ( me personal prefrence) ....also many members here have R3 which they reported to be bass cannon but me bought them early 2013 which has a balanced sound sig with copious amount of clarity and bass light too .....
FYI ..also have 668B ..cheers
