Posting this to get some visibility on a BlackShark V3 Pro firmware bug that a lot of us are dealing with.
I keep my setup minimal and prefer not to have Razer Synapse running in the background on Windows startup. My other gear (Wolverine V3 Pro, Orochi V2, and Naga V2) all work great on onboard memory without Synapse running. The BlackShark V3 Pro is the only device that has an issue loading its onboard profile on startup.
The Bug:
Whenever you turn on the headset over 2.4 GHz wireless, the audio comes through muffled, muddy, and flat. The onboard DSP fails to apply your saved EQ curve.
The only workaround right now is reaching up to the right earcup, pressing the physical EQ button to cycle through the presets, and going back to your profile. As soon as you cycle it, the audio instantly snaps back to proper quality.
About the recent patch:
Synapse release notes recently claimed: "Fixed: BlackShark V3 Pro Series - EQ not saved on power cycle."
This might have resolved the UI state inside Synapse, but it did not fix the on-device firmware. The hardware should apply the saved onboard EQ on boot without needing the desktop software running.
How to reproduce it:
-
Save your custom EQ to onboard memory and close Synapse completely.
-
Power on the headset over 2.4 GHz wireless.
-
Play any audio (it will sound muffled and flat).
-
Hit the physical EQ button on the earcup to cycle through presets and back to your profile.
-
The audio immediately fixes itself and sounds normal.
Why this happens:
The headset boot sequence is not pushing the saved filter table from onboard flash memory to the DSP chip during the startup handshake. The DSP only wakes up and applies the EQ when a physical button press interrupt is triggered.

Can we please get this escalated to the audio firmware team for a real firmware fix?
