i have experienced my two iems got imbalance after several months plugged into my PC , i suspect it's because of my PC hasn't grounded properly (or my electricity hasn't grounded). is it true plugging an iem or earphone directly into PC with no grounded will make the iem imbalance?? does any solution for this problem like using a third party usb dac like fiio k3? it almost impossible for grounding my electricity for now.
thanks in advanced
