Following Dr. Dre , Diddy , Ludacris and numerous others, 50 Cent has become the latest star of the hip-hop world to come out with a headphone line. According to Engadget the headphones, known as Sync by 50, will feature 16-bit lossless digital sound and on-board controls. The product is not a result of 50 Cent's previously announced collaboration with Sleek Audio; that was announced at CES this year but canceled in the spring.
