We're seeing more and more passive amps for smartphones as of late. Some of them look better than others and we've gotta say this one by Jeroen Bomers carved from a solid block of wood is pretty awesome. It's simple, just slide your smart phone into the slot and the volume will be boosted up to room filling sound. The amplifier is hand made by Malawian woodcarving and woodturning specialists. No idea when or if this'll see actual production, but here's to hoping yes.
