If Razer can come up with a firmware update to do this manually 

I would also like to know how to turn off the RGB on the kraken v4 pro while in Bluetooth mode. Turning off the brightness on synapse doesn't stop it once it's no longer connected to my PC 

I’m looking for a solution too, even in my windows PC with synapse 4 is turned off but the headset still are on… I just want to turn it off it’s not that hard Razer… I’d rather have more battery than not seeing my headset lights...

To minimize interruptions at night:

1. Disable Notifications: Go to Settings > System > Notifications & Actions and turn off unnecessary notifications.
2. Use Focus Assist: Go to Settings > System > Focus Assist to set quiet hours.
3. Check App Settings: Disable auto-start or notifications in apps like Razer Synapse.
4. Use Sleep Mode: Set devices to quiet or use a timer to stop audio after a set time.
5. Use Earplugs/White Noise: Consider earplugs or a white noise machine to block out disruptions.

Yeah, that’s annoying. If there’s no option in the app coffee machine pods, maybe try setting a solid black color as a workaround? Some devices let you dim the RGB that way.

I installed the latest firmware update, the backlight did not turn off, I am very upset. If I had known that you can't turn off the backlight in Bluetooth mode, I would never have bought these headphones. The second product from Razer with flaws. And I'm sure it's the last one.
