I've broken some very nice headphones by pulling off a Comply Foam tip in order to freshen the tip with a new pair of Comply Foam tips. My latest destroyer set is Etymotic HF5. Before that I destroyed a pair of RP-HJE900s and the Kilpsch S4. How can I more safely removed a used up pair of Comply Foam tips without destroying my headphones?
 
Oh, and I've gone back to the Kilpsch..... wow, I love these phones!!!!!!!!!!!!!!  ($49 at Amazon.com right now).
 
Thanks,
Craig
