Razer Blackshark V2 Pro - Noise from left earcup

Hello In January i bought myself a Razer Blackshark V2 Pro headset, the sound is amazing and i really like the headset! Shortly after i started having a sound in the left earcup like something being loose in there. I have now returned it to the store and gotten a brand new Razer Blackshark V2 Pro headset, which is having the same sound from the left earcup, as soon was it was taken out of the box.. Since its a pretty expensive headset i wouldnt expect issues like this. Question. Is there a fix to this? Have i just been unlucky getting another headset with the same issue? - Nielzen
