You’ve probably checked out the Monster Beats headphones by Dr. Dre before, and now Dr. Dre, Lady Gaga and Product RED have come up with a special edition of the Beats Solo HD Headphones. Aside from its obvious red color scheme, for every sale of this headphone, Monster will donate $5 to the Global Fund to help eliminate AIDS in Africa. These headphones sport Monster’s proprietary ControlTalk technology, allowing users complete access to the iPhone, iPod and some BlackBerry functions. A built-in microphone also lets you make and receive calls without having to switch to a hands-free kit. At £169.95 ($255) it’s far from a cheap product, but you do get a certain amount of quality and good looks with these headphones and you’re supporting charity too, right?
