These earplugs are the best you can buy - Very comfortable and ideal for pool and/or open water.

I have large ear orifices. These flange type work very well to keep out water. They are more streamlined than other brands I have used. My only wish is that they came in colors. If you happen to lose one in the water, about zero chance of getting it back. Come. On Finis, how about some bright. "Finis" yellow or orange?

These ear plugs were a game changer for me! In the past, I had a lot of issue with ear aches and infections from swimming. Never heard of ear plugs for swimming before, and wish I knew about them sooner. They were comfortable, low profile, and kept the water out of my ears completely. They also cut down noise a lot, which at first was a little disorientating because I couldn't hear much through them unless someone was within a few meters of me, but it helped a lot with staying calm when my head was underwater. Easy to clean, and they came in a little storage case as well. Couldn't recommend them enough!
