Hello, new here but not in audio I got used to high end products but atm no money to buy other good products so i moved my attention to budget IEM. I always listen to EDM music with many melodic and vocals parts so every frequency is important. My attention was on the KZ ZST and UIISII T8S but i've heard ZST has actually no bass and t8s sounds pretty metallic. The important things for me are : - isolation - fitting and comfort (no fatigue while listening for many hours) - balanced audio with good sub bass and punchy kicks, depth is important I know i can't pretend universe with like 30 bucks (on amazon dot Italy) but i would like to know if i could have a good IEM at this price point. (Curious thing : replacing the cable to the zst from zk, does it improve something in terms of audio?) Hope i get some tips here.. Thanks a lot!
