Hearing aid pros:
hear more cat meows

cons:
fan noise
house creaking noises
cars
planes
neighbors arguing
frikkin refrigerator
weird noise you didn't know existed but since everyone else is used to it they don't know what you're talking about when you ask what that weird noise is
(holy shit refrigerators)
TV on the other end of the house
harder to get away with the "I couldn't hear you" excuse
reflexively saying "can't hear you", but you heard them fine; its too late they're already on loop
