earplugs will block out almost all the external noise

Moldable earplugs (or putty earplugs) are made from a soft material that you can mold into the exact shape of your ear.

These earplugs will block out almost all the external noise. Putty earplugs come in two different varieties. These are wax and silicone earplugs. You can get other types, including soft plastic, which can be reused many more times.

Moldable earplugs are perfect for blocking out a lot of noise. They fill your entire ear yet do not stick out like other type of earplugs.  (For example, foam earplugs).

They are ideal for use with a second type of ear protection device, for example, ear muffs. You simply insert the Putty earplugs into your ears and then put the earmuffs over the top of the plugs. This gives you a double layer of protection, blocking almost all the noise.

You can never block all the noise from your brain. Some bones in the head actually conduct sound to your ears as well. But you will stop almost all the noise.

However, in a noisy work environment, for example, you will always be able to reduce the noise to a reasonable level

Moldable Wax Earplugs

Wax earplugs are not as common as the silicone variety. They are made from wax and a cotton fiber mix, and the fiber will help it hold its shape. These earplugs are fitted in the ear by rolling the wax into a ball. This is then gently pressed into the shape of your ear.

Being made of wax, the material softens with the heat from your body. Because of this, wax earplugs are probably one of the most comfortable plugs you can get, that block your entire ear.

The primary use for wax earplug includes sleeping, studying, and blocking low noise. However, the best use for these earplugs is when sleeping, as they are very comfortable. Also, they do not stick out of the side of the ear, meaning that you can sleep on your side with no problems.

Wax earplugs are also useful for swimming, as they block the entire ear and stop water going in. But silicone earplugs may be better for this purpose.

Moldable Silicone Earplugs

Silicone earplugs are like the wax earplugs above. However, they do not soften from the heat of your body as much. They are very comfortable, and extremely good at keeping water out and sound. As with wax earplugs, to fit them you roll them into a bowl and gently mold into the shape of your ear. You should always start with a ball and never make a cone shape and insert it directly into your ear canal. This could increase the pressure and damage your hearing.

Silicone earplugs are suitable for sleeping, studying and relaxing. As mentioned earlier, they are very water-resistant. Silicon Plugs are ideal for when you are swimming to avoid getting swimmers' ear.

Plastic Moldable Earplugs

There is one other type of moldable earplug, but it is far less common than the other two types. These are made from soft plastic, and to use it you must first immerse them in boiling water to soften the plastic. The plugs are then allowed to cool for a while, before being molded into the shape of your ear. They then keep the shape, as they need to be reheated again before the shape will change.

Should you make a mistake, the earplugs can be immersed in boiling water and re-molded

Plastic Moldable earplugs can be used many, many times, as they can be cleansed. Also, they do not lose that shape without reheating.

The major disadvantage is that they are not as comfortable as wax, or silicone earplugs

Noises when using moldable earplugs

The following infographic shows a list of the various noises when you are out and about. Any noise over 70-80db over a long period may cause damage to your hearing. A noise of over 120dB may cause immediate harm to your ears.

Other Advantages Of Moldable Earplugs

Some other uses/benefits of this type of earplug are:

  • Swimming. Doctors recommend this type of earplug to avoid swimmer’s ear.
  • Airplanes. This type of earplug can help reduce pain due to air pressure.
  • After surgery. This type of air plug can protect the ear from foreign objects and bacteria after surgery. Never reuse the earplugs when you have ear problems, always use a sterilized clean pair.

Disadvantages To Moldable Earplugs

Moldable earplugs are not ideal for all situations. They are great for blocking the ear and keeping foreign objects from entering your ear. But they are not useful in all cases, for example –

When you may want to hear conversations or other quiet noises. Some electronic hearing protection devices will reduce loud noises while increasing softer sounds. This is ideal for noisy work environments where you also need to talk. These earplugs are not the right choice in situations like this.

How long do Moulded ear plugs last?

Between four and six years. However, the lifespan will be affected by the frequency of use which can vary from person to person, as well as the level of moisture in your ear.

What are Moulded Ear plugs made from?

Moulded Ear plugs typically come in a material that is similar to silicone. They come in different sizes for kids and adults. Although there are some models available without silicone. On the other hand, advanced materials were added which help prevent irritation and reduce noise levels when worn correctly. Users also get to choose how soft or hard they want their ear plugs to be depending on their specific needs and desires.


Moulded ear plugs are made from silicone and, as a result, they are much more durable than foam ear plugs. This means that they will last for a longer period of time and still provide the same level of protection as foam plugs. They are fairly comfortable for most people and can be worn for long periods of time with little discomfort. However, some people still find the inner cords uncomfortable when they first wear moulded ear plugs.

The main advantage of moulded ear plugs is that manufacturers can tailor the plugs to the wearer's preference. Moulding allows them to create ear plugs appropriate for their desired use and comfort level and also provides a more secure fit in the wearer's ear canal. They also come in a variety of colours to match almost any situation.

Please Note: Just because an ear defender is marked, for example, "Gunshot" - it will still cover other things, like "explosions"

Other Questions

Can Kids Use Moldable Earplugs?

Yes! These earplugs can be used for children. These earplugs have all the advantages and disadvantages of the adult’s size plugs. Obviously, when buying these earplugs for children, be sure to buy for the right age range. The adult’s plugs will be too big, as children have smaller ears.


Are Moldable Earplugs Reusable?

Moldable earplugs are reusable for a few days. Yet, as they are slightly sticky, they will pick up dirt quickly. You do not want to be putting dirty earplugs into your ears. Moldable earplugs are not expensive, and many people prefer not to reuse them.


Are Earplugs Safe?

Earplugs are harmless, but if you use them a lot, they may cause an ear wax build-up, as the wax cannot get out of the ear. This can lead to reduced hearing, and possibly tinnitus, until this extra wax is removed. This can be done with drops, or visiting a doctor to have it removed.

Earplugs can also lead to ear infections. The wax and bacteria build up in your ears, causing infections. This can be painful and need medical treatment.

All these problems are avoidable. Make sure that if using earplugs, you always keep your ears clean.
