I have had difficulties with
I have had difficulties with equalizing and then infections after scuba diving. I have only used them on two dives so far, but I am totally impressed that with them in I could still hear the dive brief prior to entering the water, equalizing was easier (do not understand how this actually works because of these plugs so could be a coincidence) and ears were completely dry afterwards with zero issues. Will use every single time for any activity involving water. They even stayed put the entire time but the neck strap is reassuring and makes it less likely I will drop and lose one (or both) after a dive. Finally, shipping was amazingly fast coming from another country in roughly a weeks time. Would 100% recommend to others.
