I got one today. my employer finds my earhole too big so I had to buy a flesh tone hider plug.
I think you're able to still see it, but not when you're not focusing on it.
They are kinda hard to get in at my size (og) so i cut of a little bit from the edge to get them in easier.
how it looks.
I think it's good they excist, otherwise I would have been fired lol
