For those of you having problems with connecting to the dongle, go to https://mysupport.razer.com/app/answers/detail/a_id/4166 and update both dongle and heaset firmware by folowing the directions and instructions on the updater application.

My headset is not able to connect to the dongle either. Firmware is up to date as suggested.

Please advise what else I can try?

when plugging my dongle in it plays the usb connect sound but then instantly disconnects

 Im running into this same problem did you find a fix?

You guys solved the problem? I have the same as i bought the headset today

Recently my BlackShark V2 Hyper Speed got the exact same issue.
I had follow this article: https://mysupport.razer.com/app/answers/detail/a_id/5994

To repair my USB dongle and the headset.
All are working fine for now. I’ll update if it’s failed again.

Does the BlackBerry V2 HyperSpeed ​​headset work on PS4?

hi guys, maybe stupid question but did you try to click the switch mode button on headset twice quickly? 
when my headset came it was default in bluetooth mode and didn’t see/connect to the dongle, when I press this button twice quickly, mode changed and it connected itself to the dongle stright away. 

What did you do exactly? When I click on the link i get to the headset selection page. And then? I updated the firmware of both like in the article of another comment. Do you mean the same thing or something different? 

I think this is a general problem with the usb hyperspeed dongle. I face the same issue with my mouse and keyboard too. The dongle connects and disconnects immediately. Firmware is up to date.
