All those fancy new headphones flooding the market may find themselves up the proverbial creek, as Apple looks to be doing for iPod accessories what it once did with music - lock out all competitors.

According to Apple rumor site iLounge, Apple's new devices - starting with the iPod Shuffle - will require third-party headphones and adapters to include an Apple-licensed chip to function. That means headphone manufacturers would have to pay Apple for the chip.

The Shuffle, for instance, relies on headphone-based controls to skip and pause music. While other headphones will stream the music, only authorized accessories will have the ability to control the stream.

Whether this feature will extend to future iPhone devices in not clear, but several Apple enthusiast blogs are already up in arms about the potential.
