It’s uncanny how well even the simplest passive acoustic amplifier can improve the sound that emanates from tiny handset speakers. Even though I have yet to experience the pure acoustic awesomeness of the iBamboo from New York area Etsy member Anatoliy Omelchenko, I still find that the design compliments the elegance of the iPhone 4. Produced from a single bamboo segment and finished with a black lacquer coating, the iBamboo passively amplifies handset audio when placed in the recessed dock.
