why does my microphone make this humming sond?

[SiimOK]

could it be ground loop noise?

even when I remove the xlr cable from the mixer it still makes the humming noise

If it's a low frequency sounding hum, yes, it's a ground loop.

 

Make sure all of the equipment is on the same outlet or circuit if possible.

It is maybe I should disconnect ground wire from the outlet ? Because I can't cut of the ground pin because I live in EU

Judging by the recording, it doesn't sound like a grounding issue to me. Can you please post details of how your audio system is wired in order of how they're connected? (for example: SM58 mic, XLR cable, Behringer Q802 mixer....)
