Griffin AirCurve Play for iPhone 4

10 decibels louder. Magically.

According to Clarke's Third Law: "Any sufficiently advanced technology is indistinguishable from magic." AirCurve Play is based on some very advanced technology, indeed; and when you hear it, you will agree it is magical.

AirCurve Play makes the speaker of your iPhone 10 decibels louder... no, really. And it works without batteries or cables or power adapters or incantations. Just slip your iPhone into AirCurve's rubber dock gasket, and your iPhone 4 becomes the perfectly portable audio/video conference phone, and self-contained music player and video viewer.

Without revealing the secret of the magic, we can tell you that AirCurve is a cleverly designed acoustic amplifier that collects the sound from the built-in speaker of your iPhone, amplifies it in a built-in coiled waveguide, and projects it out into the room. AirCurve's transparent polycarbonate body lets you appreciate the waveguide's graceful curves, inside, that do all the work.

That's some great-sounding mojo.
