Volta Sound Block for iPhone

The Volta Sound Block is a passive sound amplifier for your iPhone. Passive amplification means no electronics, no chargers, no blue-tooth gadgetry to mess around with. Just a solid block of Northwest Alder from our backyard here in Oregon, and a Bison horn, allowing us to draw the maximum volume from your iPhone speaker.
