The most popular music device on the planet is the Apple iPod, which as expanded to include the Apple iPhone and Apple iPod Touch, sometimes called the iTouch, and just recently the Apple iPad tablet. But in order to get the most from these devices you need accessories: speakers, docks, chargers, wireless broadcasters, cases, cables and more. Cases provide protection from everyday use and accidental drops and spills. Chargers provide a constant charge or refill the battery's capacity. There are cables that split the audio for more than one listener, or attach the device to computers and stereos. FM transmitters broadcast your music to a nearby radio so you can enjoy your music while driving in the car. Docks and speakers let you listen to your music on larger systems and not just through headphones.
