"Item Serial Number is Unknown" When trying to register Razer Kraken V3 X

I'm having the same issue, haven't found an answer, but following this thread.

Quick update on this Raised a separate support case with Razer support on this and after providing the required info so far all I have been told is that "since the device is new possible SN is not yet registered in our system." It's a bit frustrating as I'm required to register the device to access some features and so far I'm just not able to. Currently waiting to here back to see if there is a way around this. Will update here if I have any success.

same here, from Singapore, fuck this headset, it's shit

Ok so I finally got this sorted out. They didn't say what the problem or fix was but sent on the serial number and product number and asked me to register the device. To be clear they sent on the exact same serial number and product number I had sent them originally so I guess it really was just not in their system. I entered the details again and was able to register the device finally. So for anyone else having this issue just get a support case open with Razer here https://mysupport.razer.com/app/warranty-support/ they will ask for: The serial number - photo of it on the device or box that came with it Date of Purchase Place of Purchase Proof of Purchase - Invoice or order confirmation showing the purchase(you can omit any private info like your address or anything related you your credit card, that's what I did) Hope this helps anyone else having similar problems
