Static sound on Left side of my Sony WH-1000XM6

Hi everyone, I’m hoping to get some advice from those who might have experienced something similar, especially if you’re in Malaysia.

I’ve been using my Sony WH-1000XM6 headphones for almost a year, and only recently I started hearing a constant static / radio-like noise. It’s really noticeable in quiet environments and it’s starting to bother me a lot.

Here’s what I tested:

- The noise happens even when no music is playing

- It’s still there when Bluetooth is OFF

- It happens even when ANC is turned OFF

- It sounds like a constant faint frequency/static, not from the hinge

I initially thought it was just normal or something from the music, but now I’m pretty sure it’s coming from the headphones themselves.

Has anyone experienced something similar with Sony headphones?

- Is this a known issue or defect?

- Did you manage to fix it?

- If you sent it for repair, what was the outcome (especially if close to or after warranty)?

Any advice or shared experience would really help.

Thank you!
