Have you ever been to a coffee shop and when you are listingto your music and your headphones are just not cutting it, a megaphone is over kill. If you have had this problem thin I have the perfect solution. I give you the Coffee Cup Speaker. You can make this for under $10.

Step 3: Inserting the Speakers
