50 Cent
Like Dre, 50 Cent was not content to just sit around and lend his name to some other company's product. He went and acquired KonoAudio in 2011 and rebranded it as his own. Now serving as the head honcho of SMS Audio, 50 Cent is an annual fixture at CES, peddling his headphones and embarking on the Sisyphean challenge of conquering the Beats Audio empire.
