h, the Griffin AirCurve looks like a simple, elegantly minimal stand for your iPhone, but non! It’s actually a built in speaker for your gadget using “passive technology.” Inside is a cleverly designed coiled waveguide that collects the sound from the built-in speaker of your iPhone, amplifies it, and projects it into the room. Made of translucent polycarbonate, it gleams beautifully anywhere. And the best part? It’s only $19.99.
