How The Mysterious Boost Connection-Less Speaker Works [Review]



A few weeks ago, I wrote about the iFrogz Boost, a magic box which amplifies the sound from an iPhone or other device just by being close. You put the iPhone on top and the battery-powered iBoost speaker goes to work, making everything louder.

The technology used is called near field audio, or NFA, but nobody would tell me how it works. Luckily, the iFrogz folks sent me one, so I took it apart to see what’s inside.
