Just the tubing

Use an old earbud for the in-ear portion or just leave it out if you can secure it to your head without it. Nitize gear tie for the over the ear piece. A small socket head for the silver portion connecting to the clear skinny portion and a silicon tube for the clear skinny piece by the cheek. You can paint the end silver too or use sharpie. Hot glue or super glue to assemble.

here’s the one I got and I haven’t noticed a smell so far
