Ever heard of the term ‘NearField Audio’? Now you will, because that’s the promise of the BOOST Speaker from iFrogz. Just place your device with a built-in speaker, say an iPhone, and the speaker will amplify the sound through the aforementioned NearFA technology. The small box houses a couple of 2W (root-mean-square) speakers that should be good for filling up a small room with sound. The technology doesn’t use a mic for amplifying sound, just some clever circuitry to make it work. $40.
