Reddit reviews New Spy Earpiece Bluetooth Invisible Micro Earphone Mini Wireless Covert Hidden Earpiece

I was thinking about the whole pro scene cheating and I see that players still bring their own keyboards, mice and headsets which in most cases can be modified to run cheats undetected. Now for the more elaborate theory: for about $30 one can build a battery powered device that is fitted into player's shoe and can "poke" specific toe in response to somebody in the live audience sending updates of action! Right foot is A site, left foot is B site - now we get the combination of number of "pokes", length of them and position. With enough training you could be getting VERY detailed intel about your enemy positions in a way completely outside of the context that's being watched for cheats.

Edit:

Another way of enabling ez cheats would be using a headset like this with a direct feed of the casters within the arena. I wish to see how teams are performing when their sound proof booths are also faraday cages! Remember that what makes a cheat a great cheat is the fact that nobody would even remotely suspect you'll go that far or do something so outside of the box. Oh, have I mentioned they are playing for hundreds of thousands of dollars?

There's a million blue tooth micro ear pieces online.
