Edit: Solved

For all who have the same problem try to remove The Synapse program, restart the computer
Reinstall the synapse, im using synapse 4.

Conect only the headset, let install the drivers reboot Windows then conect the dongle and switch the headset to hyperspeed wireless mode (unpair for any past devices bluetooth).

Hello everyone, I'm having some trouble with my Razer Blackshark V2 HS headphones. Over time, they started disconnecting, and the dongle is now recognized by the system as an unrecognized device with error 43. Does anyone have a solution?

 

I've tried RazerBlackSharkV2HyperSpeed_0565056E_FirmwareUpdater_v1.6.11_r2 and RazerHeadsetPairingUtility_v1.11.00_r1, but they didn't help. The headphones work perfectly via USB or Bluetooth.

Hey ​@brunomrasilva,

Can you test the headset on another computer to see if the issue persists? Please also send me a PM with the serial number so I can verify it in our system and check for applicable troubleshooting steps that might address the connection issue you're currently experiencing.
