Razer Blackshark V2 pro (2020) - Dongle replacement

Hello,

I need assistance getting a replacement USB wireless dongle for my Razer BlackShark V2 Pro (2020) headset. Unfortunately, I cannot retrieve the serial number because the serial sticker has fallen off and I have lost the original packaging box.

Here is what I have already tried:

  • Removed both ear cushions to check for the serial label
  • Looked around the left earcup, yoke/arm, and headband
  • Tried connecting the headset to Razer Synapse, but the device is not detected (so I cannot retrieve the serial from Synapse)

The only marking on the headset is the part number:
P/NO: RZ04-03220100

I do still have:
 

  • My original purchase invoice
  • Photos of the headset


Could you please help me verify the device and proceed with a USB dongle replacement even without the serial label? I’m ready to provide any additional photos or information you need.

Thank you.

I have the same problem, I’ve lost my dongle, did you solve it?
