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.
