Based on the same principle as an acoustic guitar, the Original Koostik dock extends your iPhone's speakers by passing the sound through a resonant chamber. The solid-wood block won't rattle the walls of your hotel room, but it noticeably boosted our handset's output and made for richer-sounding tunes, too. Plus, electricity-free operation means you can take it camping, to the beach, or abroad without worrying about battery life or outlet adaptors. Choose walnut or cherry.

QUIRKS + CONCERNS: None, as long as you're not expecting big volume or high fidelity.
