The GT-Cube. Billed as the ‘world’s smallest hands-free wireless FM transmitter.’ Plug it into your mobile phone handset (Korean only?) and broadcast your MP3 music to the nearest FM radio or hi-fi system. Neat idea and comes complete with hands free mode for incoming calls. Neat.
The GT-Cube connects to a 10-polarity ear jack of a mobile phone and transmits MP3 audio signals wirelessly from the mobile phone to an FM radio, allowing you to listen to music at a greater volume and more enhanced sound quality through an FM radio.
