Don't put them in very far!
I keep these on my keychain.  Went to a regional nascar track.  Put these in, tried to adjust one and the pipe part popped out.  Tried to remove and ended up shoving it into the ear canal.  Had to wait 4 hours until I got home.  I was able to remove with needle nose pliers, but the ear was sore for a couple of days.<br /><br />I'll keep the case but will use some old single piece plugs that i've used for shooting instead.  I'd used them once before whrn I had to stand next to an open grand piano.
