Cristiano Ronaldo is a pretty decent footballer. He also has a knack for pitching products. This time around, he teamed up with Monster through his own company, ROC Live Life Loud, for line of co-branded headphones. "Everything in my life is about performance and quality," said soccer superstar. "We launched ROC Live Life Loud to give my fans around the world direct access to high design and the best sound quality on the market." The collection features the wireless on-ear ROC Sport Freedom ($250), wireless in-ear ROC Sport SuperSlim ($170) and the wired over-ear ROC Sport Black Platinum ($300). All three models carry glossy black and gold aesthetics and plenty of Monster and ROC branding.
