The deaf Mic HC is one I like as well.

I feel like Denki’s electric quirk would not mesh well with Mic’s gear. I bet he’d just text Aizawa for assistance if something did happen. He probably keeps a backup pair of hearing aids in his desk or something.

Also? I can imagine someone like Toshinori knowing sign language as a just in case. The man wants to be able to help everyone, after all.
