BlackShark V2 HyperSpeed randomly switches EQ preset and Bluetooth mode

Hello, I am using a Razer BlackShark V2 HyperSpeed with the HyperSpeed Wireless Dongle on my PC. The headset randomly changes the EQ preset by itself (Game, Custom, Movie, Music) while I am using it. After that, it sometimes switches from HyperSpeed Wireless mode to Bluetooth mode without me pressing any buttons. This happens even when I am not touching the headset. I have already tried: - Updating the headset firmware to the latest version - Closing Razer Synapse completely - Reconnecting the HyperSpeed Wireless Dongle - Checking the wireless connection However, the problem still occurs. The headset is over two years old, so I understand that the standard warranty period has expired. Could you please advise whether there is any troubleshooting method or paid repair service available for this issue? Thank you.
