Hiya, yes the first thing I did when I bought the headset was to do the firmware updates for both dongle and headset with cable attached, but I let them charge fully before doing this.
I get the white noise whenever I connect via wireless and USB on Ps4 but on PC I only get it through playback on microphone.
Unfortunately I got impatient and sent the headphones back, as for the £150 price tag I personally didnt think I should have been having issues like this.
I personally thought the problem was directly software related rather than hardware as it worked from the Jack perfectly fine.
I loved the headset itself, it was comfortable and the audio quality was fantastic, just a shame that the main reason I bought it was for wireless connectivity and the microphone quality.
They might send me a replacement in which case I'll try again but I have a suspicion that I will have the same issue.
