Tennis Ball Headphones

Step 2 Position and Attatch the Speakers

Now that your speakers will fit into the tennis balls, you will need to position them so that they feel relatively comfortable and get a good sound. It may take a while for you to position them just right.

After that, take out your hot glue gun and glue your speakers into the tennis ball halves. Also glue your wires into those notches you made in the tennis ball.
