No. I don't lose seal whatsoever. Also, I use them on the go.
But if you're laughing very hard(ie. reading the UM3X thread), your canal
is change shape, which would start to break a bit seal. I never bother
me. I believe some universal fit will break seal already.
But when you're dealing with customs, imo, the fit either work or not(which needs re-fit).
