Men - buy the long stem version
I bought the short stem version of the Downbeats earplugs. I have fairly large ear canals, as I think many men do. In order for the plug to seal, I have to put it so far into my ear that the stem is hard to grab. I probably will buy the long stem version because the plugs work and are about as comfortable as earplugs can be. Three stars due to the hassle. The product page says try the long stem for larger fit, but I didn't see it. Because the plastic is somewhat stiff, these plugs irritate my ears if I wear them for sleeping. They're fine for an hour or so, but not overnight.
