Best eartips compatible with Earfun Air Pro 4 earbuds?

I like silicone eartips and the ones that come with the earbuds are fine. But I've seen comments on this sub that suggest that some folks buy different eartips for the Earfuns that either enhance the sound or help with noise cancelling. I'd like your suggestions if y'all have any? I've been kind of looking at the 2-3 flanged tips, but I don't think they'd fit in the charging case.
