Ok, I'm having absolutely no clue what is happening, but for some reason every headphone I try on my laptop stops working on 1 side after a day or 2-3... I'm at my 4th headphone now, using it for 2 days and guess what? One side not working anymore... You'd think it's a software thing, a virus, or something like that... But the moment I plug in another headphone it works on both sides. So, what could be going on here? Is it possible that something in my laptop is causing some electric disturbance that messes up the headphone on one side? Looks pretty weird to me!
It's either your buying cheap headphones or there is something wrong with your laptop. Maybe a new one? - Prilep
