Hi I've been to the grand prix several times and had those foam ear plugs which work OK ish but I was wondering if anybody knows where you can get the ear plug/phones that the drivers use?
If you don't want to go down the expensive route of moulded plugs (which is what the drivers wear) try wax ones e.g. Boules Quis Ear Plugs. Just make sure you get the cotton-covered ones as they are far, far better
