You want a pair of ear plugs but you don't know whether to get moulded or a regular variety. Here's some advice on professional moulded ear plugs vs regular ear plugs.
Professionally moulded ear plugs are far more comfortable because each is made for your ears individually. They don't expand and press on the delicate skin of your ear canals unlike foam ear plugs. They stay in much better as well because they fit like a hand in a glove. Foam tends to push itself out as it expands.
Although moulded plugs cost more to buy at the outset their cost-per-use is much less than other types of plugs. This is because they last for years and thousands of uses. The cost per use can be a small fraction of a penny. Some other types of plugs like the soft-silicon varieties can be tens of pence per use as they need to be replaced frequently.
ZenPlugs Moulded Ear Plugs have a distinct advantage over professionally moulded ear plugs. This is because they cost far less but give similar results. They last for years but unlike professional ear plugs they can be remoulded as many times as you like. If your audiologically moulded plugs don't fit they will need to be remade from the beginning.
Some people find that their ear canals change shape over the course of years. They can remould their ZenPlugs so they still fit. If they had spent £90 or more on professional plugs they would need to have another set made. ZenPlugs can also be connected on a cord which is provided in the kit. In most cases when you have your plugs made at the audiologist you need to buy your own cord at extra cost. What a con.
