I don’t know specifics. He went to the doctor, they sent him to a hearing specialist, who said he’d be fine but to mind loud environmentsn for the next while (which he told me at a loud bar that night.) He mentioned ADHD and forgetting/not feeling like grabbing his ears on site when he wasn’t around tools, so they figured earbuds he could wear all day long were the best way to protect his dumbass from himself.
