There’s mould in the coconut.

This side is a bit bigger than that side… by about a centimetre – maybe a little bit less. I’ll just slice a bit off here.

They’re pretty snug.

They feel pretty good.

They work pretty well.

Noise level is definitely dampened.

I think I could have segmented the coconut a little bit differently so the shape would mirror the sponge a bit better. These are obviously ovals, and when you cut a coconut directly in half, as you would normally do, you get circles.

If you are a board of your… normal, traditional ear defenders you can make something a little more interesting.
