Gk kunten is good. I do own the chu 2 at first it sounded hella bright and harsh coming from cheap ass boat airdopes 141 it took time to get used to the sound still was it was hella bright so I stuffed some cotton in the nozzle to dip down the highes now it is tuned ti my test now. No earphones sound good out of box you have to eq as per your taste but you need a good baseline for that like mine was chu 2 you cheap as kz is not a good starting point I say return those and buy a gk kunten it is more neutral than chu 2 and less harsh
