The 'Keychain Speaker Amp' is a cutesy miniature sound machine that gives off some loud music. The keychain snaps onto your key set and away you go bopping away to the music of your choice.
The Keychain Speaker Amp packs a lot of sound for such a miniature machine. It's able to hook up to your MP3 player or iPod so you can groove to your favorite music out loud -- and annoy all the business folk on the subway in the morning while you're at it.
