Headphone to earmolds
A headphone to earmold adaptor. Earbuds of my ipod kept falling. Using this earmold specially designed for audio prostethics, I just carved a socket into it so that the standard sized earbuds headphones will fit into it. Now I can listen to my ipod and the earbuds will remain in my ears even when chewing gum!
