So Ed doesn't have a mic and often shares one with kiyome. As such, steam chat (which doesn't allow you to mute specific people) sometimes doesn't work so hot.

When playing games with both Ed and Kiyome, we often use Dolby Axon:

If Ed's not around, we'll probably just use steam chat for its hop in/hop out convenience.
