hi! i'm new here.. i'd like to ask for some help. diagnosis and repair.. i have a A4tech hu-200 usb headphone. now it only plays the right channel.. but before that happened i noticed that the audio is like panning from left to right til it could only be heard in the right. i researched about repairing headphones and all i saw is that the problem could be a loose wire or something similar but when i open my headphone there were no loose or broken wires. what could be the problem? and how do i fix it? i don't wanna send it to a repair shop cause i wanna see if i could repair it myself.

Remove the USB wire entirely from the headphones. Replace it with a proper headphone wire. Plug the new wire into your soundcard.

Mmm, bacon! Now you made me hungry.
