Have some old speakers sitting around collecting dust? If so, those ancient boxes can finally be put back to use. With this new product, The Vamp, you can connect any of your bluetooth enabled devices to this little box, then play the sound through the ancient speaker. All you have to do is connect the speaker wires to The Vamp and connect your device via bluetooth. The Vamp holds a charge for up to 10 hours. The only downfall to The Vamp, is that right now it only produces mono sound.
The Vamp is a Kickstarter product though, and the inventors need $53,000 to finish off the project. When the final product is released to the public, its price will be a little more than $100. Which is still cheaper than an iHome and some other bluetooth enabled speakers.
