Oke, about noise on DX160, i just try to find out what is really the problem. Some said that it's because screen on. Not on my device. So i try turn on airplane on, playing song from downloaded spotify, i did't hear those annoying noise, it's dead silent. Then i try turn on wifi, there is a strange noise when wifi to connect (like tiittt) and when it's connected to, i can hear those annoying noise again. So look like wifi is causing those noise. But i will try a few more days, is it really wifi cause noise (RF interference).
For other whose not hear any noise when playing streaming music app, just want you to know, i think it's only affected iem with high sensitivity. I have 5 IEM, only 2 of them i can hear those annoying noise. On Shozy BG and CIEM Avara AV3, i can hear those noise. But in Fiio F9 pro, Kinera Idun Deluxe and Phonak PFE112 i cannot hear any noise. So if you cannot hear those noise, its very lucky of you hahahaha.
