Corsair vengeance 2100 Mic loopback and weird nice when shaking it (no buzzing)

Hello, i just bought a Corsair vengeance 2100 wireless headset and when im shaking the headset i get a weird noise like i'm dragging the microphone to a shirt.
And I can hear my self talk, I have unchecked the microphone check in bouth the corsair software and in windows, anyone have any ideas whats causing these two problems?
