👂 Earplugs

Earplugs — foam, silicone, or wax — are permitted everywhere without restriction, so screeners will not stop you. There is nothing to accidentally do wrong with earplugs at a security checkpoint. They pass through X-ray without triggering any concern.

There are no regional differences whatsoever — earplugs are unrestricted in carry-on and checked baggage at every aviation authority worldwide. No country treats them as a restricted or controlled item. You can carry as many pairs as you like.

Yes — a small pair of foam or silicone earplugs in your pocket will not set off a metal detector, and they are too small to be of any concern in a body scanner either. You do not need to remove them from your pocket, bag, or ears at the checkpoint. This is one of the easiest items you will ever take through airport security.

There is no security reason to check earplugs — they are fully permitted in carry-on. The only practical reason to put them in checked baggage would be if you are packing them with other toiletries or travel supplies already in your checked bag. For a flight, keeping them in your carry-on or even your jacket pocket means they are immediately accessible when you want them on board.
