I really hate silicone tip earbuds and the AirPods 4 with ANC were game changing. Having ANC without the silicone tips was just huge for me. It's obviously not as good as having the passive isolation of the silicone as well, but it's plenty good for airplanes and trains.

Are there non-Apple alternatives that also accomplish this?

I have searched far and wide and have found nothing. I haven't even found a basic-functionality wired earbud that matches the AirPods frequency reproduction.
