iPod shuffle chip
One of the biggest complaints about the new iPod shuffle is that Apple’s removal of buttons from the unit itself onto the earphone cable forcing users to use the included earphones. Over the weekend it also became apparent that Apple was including some kind of authentication chip in the earphones, this would make it impossible for third parties to develop earphones for the iPod shuffle.

Today the story has developed further with Apple and manufacturing partners downplaying rumours of an authentication chip but manufacturers wishing to develop headphones for the iPod shuffle will have to have a license from Apple to be part of the “Made for iPod” program.

Apple has been using the “Made for iPod” program for several years to help protect consumers from buying products that weren’t designed to work solely for the iPod. This is the first time Apple has required manufacturers to be part of the program to create headphones.
