The famous footballer announced this week he has co-founded a new consumer electronics company called ROC Live Life Loud that will sell products, including headphones, to his fans.
The business has been founded in partnership with Monster Products and will be launched exclusively with eBay.
In the PR stunt, the footballer is seen dressed as a homeless man surprising passers by with his tactical skills.
"Everything in my life is about performance and quality," said Ronaldo.
"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."
