This is a preliminary review--don't want to get into a debate about other types of ear protection. So, I purchase a couple of pairs of the World's Finest Ear Plugs (their name, not mine). Kinda pricey for ear plugs, but I continue to search for some ear protection that doesn't hurt after awhile. Howard Leight Max Lite's had been my plug of choice before this: hard for me to insert properly, if I get them in they provide great sound reduction, but they start to irritate and sometimes hurt after a few hours. All the plugs that have to be inserted into the ear canal bother me after awhile, unless they are so loose they don't really block the sound. So far I find the World's Finest Ear Plugs (WFEP) very comfortable. They mold almost like blue modeling clay, smoosh into the outer ear easily, and have fairly good sound blocking but not as good as the Max Lites. Have only used them for an hour or so at a time so far, but they remain comfortable. I haven't quite figured out how to consistently get them to block all the sound. This morning I smooshed them into the outer ear, all seemed good, but I was getting more noise than I wanted so I stopped after about 15 minutes, took off my helmet, and repressed them in, and the sound deadening was much better. Not sure why the problem. After my few initial runs I would say they are the most comfortable and easiest to use of the smoosh-into-the-outer ear type of plug. The WFEP are better than Mack's moldable silicone type of plugs, which I find pop out of my ears too easily--often mid-ride. WFEP are stickier. It remains to be seen how long I will go before I dispose of the pair and try another pair--at the price I would like to make them last a bit. The materials are all natural--bees wax and cotton mostly--so I don't think disposal is as bad for the environment as the foamy types.
