Solved! Which affordable external soundcard can I use for the beyerdynamic dt770

[DrHerbst]

I got the Beyer dynamic dt770 (80ohm) for at least 1 month now and now I am starting to get motherboard interference noise. I have a cheap external usb soundcard for my microphone but that one I am ashamed of using since it destroys the sound experience I am used to.

So, does anyone know of a good external soundcard, could even be a usb one, which does not cost more than 50pounds/euros?

Something like this?

You have no other option but USB for external sound card.
