It was difficult to narrow the plug enough to insert into ear canal, and they still leaked. I prefer silicon putty over these plugs.

The plugs expand and seal the whole ear hole, unlike molding silicone.  These worked well for my "larger" ear.  I wouldn't be swimming without these plugs.

Don't work very well.  Hard to keep in and no instructions included.

great product super seller

I have these because i get swimmers ear quite frequently. My issue with these is they never stay in, or they still leak water into my ear. Not your best option.
