Selecting the right ear plugs for you can be tricky when so many different types are available. Here are a few pointers;
Molded ear plugs - these are excellent all-round general-purpose earplugs. They are great for blocking sound and water from your ears. They last for years and are comfortable and effective. They can be connected on a cord. ZenPlugs are even antibacterial, killing all the germs known to cause ear infections, otitis and swimmer's ear. They are available in bright colours so you can find them easily if you drop them on the floor.
Wax - these are comfortable and effective at keeping water out of your ears. Unfortunately they quickly become clogged with dirt and wax, giving them a short life span. They can become hard and discoloured after a few uses and get stuck in the carpet if you tread on them.
Soft silicon - these are comfortable and stay in the ears well. Unfortunately their stickiness can be unpleasant and, like wax earplugs, they quickly become full of hair and muck.
Foam - cheap and cheerful but uncomfortable with prolonged use and can make your ears sore and itchy. Although cheap to buy initially, the cost can mount up if used long-term as they need to be replaced regularly.
