So, I happened upon a set of wireless headphones on clearance a couple weeks ago and ordered them. They weren't for listening to this case, but I hooked them up today and have been able to make spaghetti sauce, do some cleaning, go all over the house and even out on the deck without missing anything from the live stream.
Really helps to be able to keep busy while Nurmi lumbers through his questioning. I think he'd actually be more effective if he stepped up the pace. He gives witnesses too much time to figure out where he's going and, if need be, respond accordingly.
