Swimming Essentials: Choosing the Right Earplugs

Updated: Oct 10

Swimming is a wonderful activity that many people enjoy for various reasons, such as fitness, relaxation or competition. However, swimmers often encounter a problem when water enters their ears. This can cause not only discomfort, but also serious health issues such as otitis externa, commonly known as swimmer's ear. The human ear has a natural defense mechanism against water intrusion. The shape of the earlobe prevents water from reaching deep into the ear canal, and the earwax inside it sanitizes the water, killing bacteria and preventing their growth. However, water can contain different types of harmful microorganisms and fungi that can trigger inflammation in the ear canals. Inflammation can manifest as a burning sensation, irritation and severe pain. Therefore, staying in water for a long time increases the risk of ear infections, especially in moist environments that favor the proliferation of pathogens. Chlorinated water in swimming pools is supposed to eliminate various infections, but even chlorine cannot remove all the dangerous microorganisms from the water. Therefore, it is advisable to wear earplugs while swimming to protect your ears. This is especially important for children's health. In this article, we will help you choose the best earplugs that will fit your ears perfectly.

Types of Earplugs

Not all earplugs are the same, and there are several factors to consider when choosing the best ones for your needs. Here are some of them: Material Earplugs can be made of different materials, such as plastic, silicone, wax, polyurethane, or rubber. Each material has its own advantages and disadvantages in terms of comfort, durability, and performance. You should choose the material that suits your preferences and skin sensitivity. Waterproofness The main function of earplugs is to keep your ear canals dry and prevent water from entering them. Therefore, you should look for earplugs that have a high level of waterproofness and seal your ears well. Some earplugs have special features, such as vents or filters, that allow air to pass through but block water. Size Another important factor is the size of the earplugs. Earplugs should fit your ears snugly and comfortably, without causing pain or irritation. The size of your ear canals may vary depending on your age, gender, and anatomy. You should measure your ears or try different sizes before buying earplugs. If you are buying earplugs for a child, make sure they are small enough and safe for them.


Shapes Reusable Conical Earplugs are designed to provide optimal protection for your ears while swimming. They feature a unique shape that consists of multiple silicone layers of varying diameters, creating a barrier that prevents water from entering your ear canal. You can adjust the depth of insertion according to your comfort and preference. These earplugs are made of durable and soft silicone material that conforms to your ear shape and does not cause irritation. Unlike plastic earplugs, they are comfortable to wear for long periods of time.

One of the advantages of Shapes Reusable Conical Earplugs is that they are more affordable than custom-made earplugs, which are usually reserved for professional swimmers who need a precise fit. Moreover, these earplugs are compatible with the SONR system, which allows you to hear clear sound signals from the SONR receiver while swimming. By purchasing the SONR system, you will also receive a pair of Shapes Reusable Conical Earplugs for free. Another option for swimming earplugs is the elastic silicone type, which resembles clay in its texture and properties. These earplugs are flexible and pliable, and can mold to your ear shape easily. They are also inexpensive and widely available, making them a good choice for beginners or casual swimmers. However, these earplugs have some drawbacks, such as losing their elasticity and color over time, becoming dirty and less effective, and requiring frequent replacement. The most expensive and high-quality option for swimming earplugs is the individual, molded type, which are custom-made for your ears only. These earplugs are often used by professional swimmers who need the best possible protection and fit. To order these earplugs, you need to visit an ENT specialist who will take a plaster cast of your outer ear using special equipment. We do not recommend attempting to make these earplugs yourself, as only experts can ensure their accuracy and safety.

How to use Earplugs?

Earplugs are essential for protecting your ears from water and preventing infections. To use earplugs for swimming, follow these simple steps:

  • Store your earplugs in a waterproof container that comes with your SONR sets. This will keep them clean and dry when not in use.

  • Before getting into the water, insert the earplugs into your ears. Make sure they fit snugly and comfortably. You should hear a slight reduction in noise, but not complete silence.

  • Do not let children under three years old use earplugs. They may choke on them or damage their eardrums.

  • If you wear a swimming cap, check that it does not interfere with your earplugs. Adjust the cap if needed to avoid pulling or pushing the earplugs.

Enjoy your swimming with SONR earplugs!

How long can I use the Earplugs?

Silicone earplugs are a convenient and comfortable way to protect your ears from water and noise. However, they are not meant to be used indefinitely. The manufacturer recommends replacing them after 10 uses, as the silicone material deteriorates over time. It becomes darker, less flexible, and less effective at sealing the ear canal. This can result in water leakage and reduced noise reduction. Conical reusable earplugs can last longer than silicone ones. They are made of soft foam that conforms to the shape of your ear. They can be used for up to a year, depending on how often and how well you clean them. However, they are also subject to wear and tear from environmental factors. Water pressure, sunlight, and chemicals can cause them to dry out and lose their shape. You should inspect them regularly and replace them when they show signs of damage or discomfort.

Does Earplug block off sound completely?

You should still be able to hear the sounds, but much softer. SONR receiver is a cutting-edge device that uses bone conduction technology to deliver real-time coaching to swimmers underwater. It allows you to hear your coach clearly, even if you are wearing a swimming cap and earplugs. The sounds are not distorted or muted, but crisp and loud.

Earplugs for Children

Children have different needs and preferences when it comes to earplugs. They need earplugs that fit their smaller ears and that are attractive and fun to wear. That's why there are earplugs specially designed for children, with different sizes, shapes, colors and decorations. These earplugs are also made with the children's ear anatomy in mind, so they are safe and comfortable for them. They can protect the children from ear infections and other problems that may arise from swimming in the pool for a long time. Another option is to get customized earplugs for children. These are made by taking impressions of the children's ears and using them to create earplugs that fit them perfectly. This option is more expensive, but it guarantees the best protection and comfort for the children.

Earplugs are a great way to enjoy swimming and stay healthy. By choosing the right earplugs and following the tips above, you can keep your ears dry and avoid infections. Stay healthy!‍
