Kz without a doubt makes the best headphones for the price (and even above to an extent). I have the Kz ATE IEMs and they are nothing short of amazing. https://www.amazon.com/dp/B00Y0F6IBG/ref=cm_sw_r_cp_apa_.fPfAb7H7YCNM

Here you go these lasted me a year, before I gave them away, and they were regifted.

I don't remember how good they were but I'd use em for hours on end before I started getting into expensive-er set ups
