The iRon™ is a revolutionary cable free travel iRon™ for the iPod™. Simplicity is the key to the iRon's design, simply unfold the iRon™, fill with water, dock your iPod™ and "Steam Your Tunes". The iRon™ uses the iPod's battery for power and the steam jets are controlled by the tunes playing on the iPod™ . Thanks to GEAR4's unique SteamTempo™ technology, the jets spray in time to the music – fast, bass heavy tunes producing more steam and softer music providing less.
