VERY interesting product! Our company recently designed and began production of a Bluetooth speaker that fits in a cup holder or water bottle cage. Features include Siri/S-Voice integration and gesture control. We're officially launching @ CES in January.
I assume that you already have a manufacturer lined up. If not and would like to discuss... hit me up via PM.
Good luck w/ your product and video shoot!
