I went ahead and ordered the Cat Ears off Amazon last week. Got them today, already on my helmet. I guess I'll find out and report the results after Ironman 70.3 on Sunday.

Back to the subject at hand, in a way, it's nice to know I'm not alone with my symptoms. My hearing is actually pretty good when it comes to one-on-one conversations. But put me in a room with a lot of background conversation or ambient noise, and I can't understand <poop>. And I don't know if this is related or something totally different, but my echolocation is garbage now too. Once again, especially when there is background noise. I can hear noises but have absolutely no idea from which direction they're coming.
