After renting a Kangaroo at Monza last year, they are an absolute must. This is especially true of you’re going general admission – if a car crashes on the other side of the track you have no idea what happened, just that they’ve suddenly gone missing! Commentary at a lot of tracks is near impossible to hear due to the noise of the cars, and it’s usually in multiple languages, so you can miss a lot.
The headphones give you hearing protection too and it’s easy to hold and navigate around the different options. You can rent them for the day or the weekend and as was noted above, headphone splitters allow 2 people to share the same unit. The picture quality was excellent too.
