Rechargeable Battery Packs

Q:  Sounds like an awesome product, but the only thing stopping me from buying
    it is the triple A batteries. For an xBox 360 product, it should at least 
    be able to use the battery packs that are used for the controllers. Make a
    model that lets you use the rechargeable battery packs and I'll buy it.

A:  The battery pack from the controller is big and heavy. So if it were 
    sitting on one side of your head, it would weigh down that side of your 
    head. Check it out on the wireless controller and you can compare the 
    weight of 2 AAA batteries on one hand and the battery pack on the other.
