Anyone else's Buds4 Pro randomly switch from Ambient Sound to Noise Cancelling?

I've been trying to figure out if this is normal behavior or if something is wrong with my settings.

I keep my Buds4 Pro in Ambient Sound mode while I'm working. But whenever there's a sharp, high-pitched noise—like a squeaky door hinge or even the "S" sounds in my own voice—the earbuds suddenly switch to Noise Cancelling for a couple of seconds before automatically going back to Ambient Sound. I am using my Buds with an S26 Ultra and Watch Ultra.

A few things that make this confusing:

- Adaptive Sound is off.

- This is my second pair of Buds4 Pros.

- My first pair did the exact same thing, so it doesn't seem like a defective set.

The biggest issue is that it happens during conversations, so people's voices will suddenly get muffled for a second or two before Ambient Sound comes back.

Has anyone else experienced this? Is this a known software bug, an intentional feature, or is there a setting buried somewhere that I'm overlooking?

I'd really appreciate hearing from anyone who's been able to fix it.
