[Jessica Jones] Why does no one just plug their ears when they go to take on Killgrave

I Realize his virus would still effect you or whatever but if you can't hear him give a command it seems like that would give you sometime at least before he figures it out and starts writing things down. 

It isn't a permanent solution but it seems like Simpson or Cage or somebody could just plug their ears and then beat the shit out of him.

Ear plugs reduce noise, but don't eliminate it. It's a viable strategy to drown out his words with loud noise or noise canceling headphones up until one of his other thralls neutralizes your advantage. Plus, he can use non-verbal communication to control minds; if he holds up his hand and mouths stop, you will stop.
