Stuffed-Animal Headphones

Step 3 Insert the Earpiece.

First of all, check to see a) how thick each animal's "fur" is, and b) what kind of earpiece you are dealing with. For example, my earphones had a kind of hard, thin, plastic cup around the speaker itself. Not something I would want jabbing into my head. The tan-colored bear had thin-ish "fur", so when I inserted the earpiece I left the foam disc on. The koala, however, had very thick "fur", so as to avoid muffling of the sound I took the foam disc off. Due to the thickness of the "fur" I thankfully could not feel the speaker inside.
But anyway, insert the speaker, noisy-side up (meaning facing the back of the animal). This is where some glue could come in handy, but again, I didn't need any.
