I made this a few months ago, so i don't have any pics of making it yet but i will soon.
Step 1: Supplies
1 Headphone cord
2 Small speakers
1 Beef jerky chew tin (plastic)
A hot glue gun
An X-Acto knife/Scissors/Drill
A hair dryer
Step 2: Preparing
Cut the speakers off of the cord (If it still has them).
Step 3: Soldering
This step is important, because the original speakers on headphones are too quiet.
Step 4: Assembly
Then glue a portion of the cord into the bottom.
Step 5: Done!
I accidentally used the wrong speakers so mine is quiet.
