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.
