The iPod was the first and most popular MP3 player and still remains a music icon. It didn’t just stop with the music player, but rather continued into a collection of various models as well as accessories. Some of these include portable iPod speakers, cases, earphones and the iTrip. The iTrip allows one to listen to one’s iPod in their car through a cable that connects to the radio. This way you can listen to your favorite songs on the car speaker.
