This tiny and stylish FM transmitter that plugs into the headphone of any MP3 player lets you transmit your favorite music to any FM frequency. Yes, you got the idea--this is very useful for listening to music in your car. A perfect alternative for those who don't have a tape player in their car, but want to enjoy their iTunes downloads. The Audia-x works with a 1.5v battery or with a car power adapter (included) for your long cross-country trip. Setup is a breeze, no need to read the user guide. The only drawback: you might need to change the frequency once in a while when a real FM radio station is overlapping with your frequency.
