And i know ed12 is a failed kz product. I tried that and it feels weird, or its my sound perferences? I currently have a zs3 and zse. How would u guys rate es3,zs3, zse, zs5, zs6 and zsr in terms of best to worst, not taking the price into consideration I am not a bass head, i am more of a vocal person? Esp those vocal music with min background music. Something like untitled by G-Dragon, empty by winner, white night by taeyang, thinking out loud and photograph by ed sherran, Loser and If you by big bang.
