Sorry, should have put a picture Ahh that makes perfect sense now, thanks Aberrant! Feel a bit daft now asking!
The final wasn't too bad for the grunting and screeching at least.
I find the headphones a bit disrespectful, especially when being cheered on to the Court by the crowd, I think someone like Martina Navratilova said the same, that's it's a lack of respect for the crowd, seems they may be tied up in a sponsorship deal though to get money for wearing them on to the Court as advertising.
I'm also intrigued about all the different drinks they have between points/sets, most of them seem to drink from a number of different bottles and all seem to eat the same thing, though never been able to see what that it, seems like a thin bar of something they nibble from. No sign of any bananas this year, that I've seen anyway!
Thanks all for your answers.
