Dr. Dre, Ludacris, and 50 Cent. The Gravedigga sometimes known as Bobby Digital is teaming up with WESC to bring the world Chambers, a line of over-ear headphones with flashing LEDs that light up in time with your music. Chambers will come in two versions -- one targeted at consumers and another aimed at pros. The line is set to launch on August 26th. It's not quite as awesome as that $500 Ghostface Killah doll from a few years back, but it's a start.
