Dear everyone, I've used Creative EP-830 with my Conwon S9, and now I want to look for a better in-ear which costs under 100$. I listen to many kind of music (Rock, Pop, New Age). Which in-ear should I buy? In my country, there are some popular producers such as Sony, Hifiman, Vsonic, Dunu, Sennheiser, ATH, Denon. Thank you so much.
