As any iPhone user knows, listening with their phones' built-in speaker is not exactly an audiophiles dream. iFrogz designed "Boost" to amp the tinny sound; just place your device on top of the black brick while it's playing and voila! - you've got a speaker.

So how does it accomplish this? By using what's called Near Field technology, it syncs the audio signal from inside your device and then pumps it out the two 2W x 2RMS speakers. No wires, no bluetooth, no nothing. (There is an auxiliary line-in jack is provided for devices without external speakers.)

While it doesn't compare to listening with your Bose computer speakers, it sure sounds a helluva lot better than it did before and you can take your Boost anywhere.

The Boost gives up to 15 hours of play time when powered by three AA batteries - or can be powered by a Micro USB cord (sold separately). When on battery power, it can remain in Standby mode for up to 6 months. The little black box is a great way to amp up your music.
