Thank you for pointing out that the Soundcore over-ear headphones are good. I've wanted to try this brand again because of the price point.
I've tried two different versions of the Soundcore in-ear noise cancelling buds and none of them did anything remarkable, IMO. I always went back to my Bose over-ear NC headphones.
I wonder if that's just a consequence of earplugs not being as good as earmuffs in general, though.
