M100 Whistling Noise

Hi all,

I love the headphones but there’s now a high pitched whistling that’s started in just the left ear bud. It’s more prominent if I try to adjust the fit.

I am going to try a different bud but I wondered if anyone else encountered this?

I am using the silicone buds (not foam)

I have them Noise Cancelling (high level) exclusively.

Thanks!
