Buds3 Pro <> Buds 4 Pro Ear Tips compatibility

Did anyone see or read somewhere whether Buds4 Pro ear tips are identical to the Buds3 Pro ones by any chance.. aka.. will replacement or aftermarket ones for the Buds3 Pros fit the Buds4 Pros?

Not guesstimating, just wondering if someone saw / actually knows whether they are (or not)?

Thanks!
