My headphones aren't working on my laptop but speakers do

Hi,
So you could say my headphone jack is not working for some reason, but when I try to use a usb to headphone jack converter my headphones still don't work. I can hear a sound but its distorted and annoying. By the way I can hear the sound when using both the usb and the headphone jack.

Pls help, I'm trying to make music on my laptop and as you could imagine this is a very annoying problem. Also I have a laptop from the states and I live in denmark so I don't even know if i can get it fixed here.
