Rock-It 2.0 portable vibration device makes anything a speaker
So I was sitting at the breakfast table the other day and looked at the box of Frosted Flakes and thought: "Wow, that cereal box would make a great speaker!" OK, I made that up. I could have been telling the truth, however, because with the Rock-It 2.0 portable vibration speaker, a cereal box, bowl or any other hollow device can be transformed into a speaker.
The Rock-It 2.0 is a pill-shaped device that can be plugged into any audio device with a standard headphone jack. You then pull out the Rocket Pod and unwind the attached cord to stick the Pod to something hollow using the included sticky pads. Then listen as your tissue box, mixing bowl, coffee cup or garbage can becomes a speaker. The more hollow the device, the better the sound. Have an older iPod with no speakers? This may be a good solution for you.
The $50 price on this gadget seems pretty steep, despite how cool it is. I don't have one to test myself but the sound in the demo video sounds kind of muffled and bass-heavy. So if you're an audiophile and prefer to hear a greater dynamic range in your music than a cereal box can provide, you can look at other portable speakers for $50 that will do a better job. The cool factor of the Rock It does bump it up for me, and I can think of a few people I know who's heads would make great speakers. Remember, the more hollow the object the better the sound! ; - )
