I like to use the kid size ear plug.  The adult size seems too big

Great ear plugs for kids. We tried many diff types and brands and these stay in and work the best.

These little ear plugs are great! I used them at a Monster Truck show for my little one's as it was so loud. They stay put and really block out the sound! They are very soft and mallable, so didn't hurt their ears. My 3 year twins left them in for over an hour, it was like they forgot they were wearing them. Didn't try them in the water, so I don't know how they work there but I imagine they would be great there too. For this price, these are the bomb!

They work great.  My six year old had tubes in her ear and I thought it was going to be a strugle keeping ear plugs in her ear, but these are very confortable for her.  She hasn't complained once about having to wear them.  They were a great size too.

Exactly the same as the ones we were buying in the store, only cost less.  They work great.

Won't stay in kids' ears.  Great for sleeping -- not so much for swmming.
