I have excellent reading comprehension. I know you said you looked everywhere, couldn't find your earplugs and then concluded the housekeeper stole them. You didn't see it happen; you deduced it from the surrounding circumstances.
Your first post said the EarPlanes were left in their carrying case and then you rather gleefully surmised how disappointed the housekeeper must have been when they discovered the case contained earplugs rather than expensive music ear buds. Your posts since then have added much more detail and a good deal more explanation of how likely it is that housekeepers steal from people's rooms, even items of little or no value.
Others have pointed out how easy it is to misremember the type of details you stated here and misplace or lose small items. They also pointed out the unlikelihood of any housekeeper mistaking earplugs for expensive music ear buds and the further unlikelihood of a housekeeper stealing small inexpensive items like earplugs (not that it's never happened - just that it's unlikely).
This doesn't have anything to do with reading comprehension. If you post something like this, people will take the facts you posted and then consider them in light of their own knowledge and experiences to determine the most reasonable conclusion. That's what some of the posters here have done and concluded that it's highly unlikely (although not impossible) that the housekeeper stole your earplugs.
@CaptainAmerica just had a much more succinct way of putting it.
