The G1 Optimus Prime Head with Built-In USB-Powered Speakers is just latest item to pop up at BigBadToyStore to enhance your ever growing collection of Transformer peripherials. The head itself weighs about 3 pounds and the sides of its helmet open up to reveal a set of speakers. The controls for the device are on the back, such as the volume and it will sit nicely on your desk looking menacingly at others as they pass by it. If Optimus Prime doesn’t do it for you, there will also be a version for Ultra Magnus. There are no details on how decent sounding these things are and most likey you are not getting it for the sound. Both are available for pre-order now and will retail for $49.99.
