The W660 can store up to 470 songs (in eAAC+ format) on its included 512MB Memory Stick Micro (M2), and those tracks can be played over a Bluetooth 2.0 stereo connection so that they can be enjoyed with wireless headphones.

If headphones aren’t your style, the W660 can also be used with the new MPS-75 snap-on stereo speakers.
