Monster on Thursday releaased special edition Butterfly headphones designed by Vivienne Tam. Based on the designer's Butterfly Lovers theme from the Spring 2010 fashion collection, the earbuds have an all-metal housing that reduces resonance. A cable management system has a built-in slider and clip that will keep the weight off the headphones, reducing stress on a wearer's ears.

Added comfort comes from included slip-on rubber covers in multiple shapes and sizes for a specific user's ear. Like other more recent Monster earphones, the set has a built-in mic and a one-button in-line remote control that is compatible with iPhones and iPods for answering calls and stopping or switching tracks.

Exactly when the headphones ship is unknown, but they will cost $200.

In the past, Vivienne Tam has also worked with HP to create a specially designed Mini 1000 netbook.
