Any IEM feedback on my Unique Music Player with custom driver for Bluetooth and 3.5mm wired earphones alongwith USB DAC
I really wanna know how IEMs sound on this app because I do not own an IEM and only have Earpods Type c and a couple of other Bluetooth earphones. Any type of feedback would be appreciated.
