Hi Mate, no matter what system your using if you do not isolate - cancel out the wind noise you will fail. In helmet speakers work well if fitted correctly, by that l mean in exactly the right place to your ears and you also need to use earplugs to cancel out the high frequency wind noise, also you need to have a helmet that is snug fit and dos not let in to much wind that will cause turbulence and noise, l use a cotton neck tube to seal up my helmet. Alternatively to helmet speakers you can use the noise cancelling in ear earphones. You can get a bespoke set made which are not cheap but really good or alternatively a set like this. http://www.amazon.co.uk/MEElectronics-S ...

Again just be sure you fit the correct buds to suite your ear any wind noise getting in will render the units useless.
