Strange... At first I saw a Turbine... But it has an ellipse rather than a square O. Valve... But the stem shape is off. How old is the source? Maybe something new coming out.
Thanks for replies... It's from a recent bbc documentary when he went around the world playing football on every continent in the world. I'd guess no more than 6 months old... I agree it's very much an eclipse rather than the square logo on the turbine. But it they look squarer than the valve? Mayve it's just the angle the photo was taken at
Still convinced they are valve, he has a band on them to keep them on his head might not be an Oakley band! Can just about make out the unobtanium on the ear stems too
