When I go to games live I take along a pair of these, they allow you to hear the umpire mics during the quarter.
Gives you a good insight as to what is going on out there because you get to hear the players along with the umpires explaining why they paid what they did as well as how they communicate with each other
They look awesome.But the website says that due to the AFL changing their operational requirements, they will no longer be useable after the 2018 Grand Final. Disappointing! I was gonna get some.
