AirPods Max: Smart Case connect issue & left earcup sound

Hello,

I have an issue with my AirPods Max (Lightning version).

Current firmware version: 6F25.

I’m experiencing two intermittent problems:

1. The headphones sometimes remain connected to my iPhone even when they are placed in the Smart Case.
2. I expect them to go into low-power mode and disconnect, but occasionally they stay connected.
3. While wearing the headphones, after slightly adjusting their position on my head, sound suddenly plays only from the left earcup.
4. When this happens:

• • the Digital Crown does not respond
  • the Noise Control (ANC) button also does not respond
  • only the right earcup produces sound

Removing and re-putting the headphones sometimes helps, but the issue can reappear.

Has anyone experienced similar behavior with AirPods Max on firmware 6F25?

Are there any recommended troubleshooting steps, resets, or known hardware issues related to these symptoms?

Thank you for your help.
