It sure is handy to have the spare ear gels! Great program Klipsch! 
After giving my Image headphones a real workout
over more than a year (since they were introduced), I've seen the need to replace my old double flange large set.
Remember to stash your spares in a safe place so you know where they are when you need them.
Mine were in the small Image case on my shelf of Klipsch memorabilia but yours could be in a top dresser drawer or in your toolbox with 'small' stuffs.
mmm fresh ear gels mmmm
