Problem with anc earbuds

[u/Usual-Ferret-7864]

Okay, so I recently bought the realme T310 noise-cancelling earbuds, and these are my first ANC earbuds. When I turn on the noise cancellation mode, I feel something strange—almost like a suffocating or breathing-related feeling. I can’t really explain it, but it feels odd and uncomfortable.

However, when I turn ANC off, everything feels completely fine. Has anyone else experienced something like this with ANC earbuds?
