I have a FiiO e10k and a Hidizs s1 and with both of them I notice quite a lot of static noise. I have a Pc running Windows, a laptop running Linux and a phone running Android 9, the static sound is present in all of them in varying degrees. I was looking into fixes and saw that there people suggest using a micro usb cable with ferrite core to prevent this, do you think the following cable would be good to go with the e10k?
As for the Hidizs s1, I saw people recommend uapp, but as far as I could find out this still won’t work for Spotify, is that right? Also people suggested an audio over usb setting in the developers options, but I can’t seem to find it on Android 9 (miui 11, I did find the developers options).
Any tips and advice are welcome,
