If your ear plugs hurt and fall out all the time you are probably using foam ear plugs.
They expand in your ear canal which creates a great seal against sound but causes pressure in your ear canal. This can be highly uncomfortable and cause the plugs to push themselves out of your ears all the time.
They can become rough on the outside If you wash them. As well as this they become contaminated by bacteria with use, both of which can lead to soreness and ear infections. The discomfort often results in people removing the plugs from their ears whilst they are asleep. This exposes them to the sound they were trying to avoid.
The roughness can abrade the ear canal and scrape away the top surface of skin. This leads to pain and soreness. The skin normally provides a brilliant barrier against infection. If the surface is removed this allows bugs in, resulting in ear infections.
Try molded ear plugs instead. They are smooth and non-porous making them comfortable. They are also unlikely to cause discomfort and ear infections. ZenPlugs Molded Ear Plugs even contain Steritouch (R). This is a compound proven to kill the bacteria known to cause ear infection. Click 'Add To Cart' to buy a pair.
