Custom fit your iPod earbuds with PodFitKit

Quick chemistry test here... silicone sticks to nothing but silicone. Therefore, this "molding mixture," whatever it may be.... shouldn't stick to the surface of the earbud. Unfortunately.... if there is nothing sticking to the earbud... there is nothing holding it in the ear other then tension.... which isn't a wise investment. I'd look for something else... completely molded into the ear, or otherwise. One such company I know of from the shooting market that makes such a product is www.earinc.com. They molded a pair of earbuds for me at a trapshoot... and I've used them doing just about everything else. Good luck if you decide to go this way.

is it me or does it look like blue tack

my only concern is, the silicon will possibly eventually peel off the earbuds if it's simply stuck onto the edge/back of it, and not completely sealed onto the bud. another thing, wouldn't it block the vent holes on the backside of the buds, which might affect the sound quality?

KissTheRing, I applaud your spirit of adventure.

I'll do it I'm ordering one right now.

you can go with form-fitting in-ear headphones that not only have better fidelity, but have silicone cups that conform to your ear canal. i've got a pair of sony fontopia mdr-ex71sl phones (in black) and they do a great job of blocking loud ambient noises (like the bus) while still leaving me enough hearing to talk to people.

My kid has hearing aids and they make the earmolds in a similar way. Basically, they mix a two part silicone goo into each ear with a syringe-like device. After about three minutes, they take it out and send it off to a lab to get the real earmolds back. This sounds like it could work, but it would block out almost all external sound.

I got a question. Once you apply the silicon to the earbuds, do they become permanently attached to your ear? -- Which can be a good thing considering the amount of BS one can avoid by blocking out the world, for the rest of one's life.
