Portuguese soccer star Cristiano Ronaldo has co-founded a consumer electronics company, and he’s teaming with Monster for its first products.

Ronaldo’s company, Roc Live Life Loud, will feature specially-made versions of Monster’s Sport Freedom, Platinum and SuperSlim headphones, as well as its BackFloat Bluetooth speaker. A Roc Luxe model is slated for fall.

The products will initially be available exclusively on eBay, with other retailers expected to follow. Suggested retails will range from $199 to $329.
