Step 1: You Will Need:
plastic martini glasses
mp3 player (of course!)
Step 2: Cut the Speaker Cone
Separate the martini glass halves. Use the top half and cut off a sufficient amount to fit the earphone. It is better to start smaller at first. You can always cut more off, but it is difficult to put some back on!
Step 3: Place the Earphone and Secure
Put the earphone in the speaker cone and secure with the tape.
Step 4: Plug and Play!
With proper placement and finding the "sweet spot", it can be heard from an amazing distance!
