Custom-made earplugs offer the perfect fit and maximum protection. From a professional ear impression in our Dutch workshop to skilled craftsmanship with hypoallergenic materials. Every pair comes with a 100% comfort guarantee, free filter changes and a 2+ year quality warranty.
Custom earplugs, also known as otoplastics, are specially designed to fit your ears perfectly. They offer unrivalled comfort and optimal sound attenuation, because they are tailored precisely to the shape of your ear canal. Choose custom hearing protection now.
Whether you are looking for peace and quiet while you sleep, festival earplugs or swimming earplugs, there is always a type of custom earplug that does exactly that. At Audinc we have an ideal solution for every situation, so you are always assured of the best custom-made hearing protection.
Before we fit your earplugs, you first need to know which ones you need. Are you looking for earplugs to always sleep soundly? Then you need our Custom SleepzZ. For DIY work, choose Custom Hobby, and for swimming there is Dry Ears. Once we know what you are going to use the custom-made earplugs for, we know which filter is needed.

When you have earplugs fitted, you get otoplastics with a unique fit that connect perfectly to your ear canal. In addition, your sound environment is also taken into account during the fitting of the earplugs. Wearing custom-made earplugs offers several advantages:
At Audinc we specialise in otoplastics. We make your earplugs genuinely fully to measure. Together we look at which product best suits your situation.
You can recognise custom-made earplugs by their perfect fit and high wearing comfort. The process starts with fitting the otoplastics. For this we first carry out a brief inspection of the ears. We check whether the ears first need to be flushed out by a doctor. If not, we make an impression of the ear canal straight away. This is needed so that we can fit the earplugs precisely.
Before we make the impression, we place a small piece of cotton wool in your ear canal. With this we protect the eardrum. Next we inject a silicone paste into the ear canal, which you barely feel. We send the silicone impression of your ears to our lab. There we make the final adjustments to produce the otoplastics exactly to measure. This usually takes about two weeks. Do you need the earplugs sooner? Then express delivery is possible. The custom-made earplugs are then ready within 5 working days.
Custom otoplastics offer all kinds of advantages over standard earplugs. They sit perfectly in your ear, provide maximum protection and last for years as well. Your fitted earplugs are then completely perfect.
Below we list the main advantages for you:
Variety of applications: Whether you need hearing protection at work or while travelling, or are looking for something for concerts, swimming or sleeping, there is always a suitable solution.
You do not buy Audinc custom-made earplugs for the short term. They last for years. That is why we always give you a minimum 2-year warranty and a 100% comfort guarantee.
In addition to supplying high-quality custom-made earplugs, Audinc also offers extensive maintenance and service options. Because, just like many other products, fitted earplugs sometimes need maintenance and service too. You are always welcome to drop by to have your otoplastics ultrasonically cleaned, so that they feel nice and fresh again.
And sometimes, after intensive use, a repair is needed, for example with earplugs that have built-in speakers. Do not assume right away that you need new earplugs. We are more than happy to carry out small adjustments and repairs for you. Sometimes repairs are still covered by the warranty, and otherwise we always let you know in advance which is more cost-effective: a repair or buying new fitted earplugs.

Because you wear the otoplastics a lot, and sometimes for long periods, you should really not even feel that you have them in. That is why we offer a 100% comfort guarantee. Of course, at Audinc we also have a solution for those moments when your fitted earplugs no longer sit 100% comfortably: the “fit test.” As soon as you notice that your earplugs no longer fit perfectly or sit well, you come by and we adjust them for you.
Audinc’s otoplastics meet all the statutory hearing-protection requirements for the workplace. When employees are exposed to noise of 80 decibels and above, the employer must make hearing protection available.
When employees are exposed to 85 decibels and above on a daily basis, wearing the fitted earplugs or other hearing protectors is also mandatory for the duration of the exposure. A plan of action must then be drawn up as well. Custom-made earplugs must now undergo a leak test both when first used and every 2 years. When it is not possible to test earplugs for leaks, they must be replaced every 4 years. For all Audinc earplugs, we are able to test them digitally and remotely.
Otoplastics and custom-made earplugs are essentially the same, although “otoplastics” is something of an umbrella term for custom ear pieces intended for hearing protection against noise or water, or for use with hearing aids. They offer maximum protection and comfort. Custom-made earplugs are otoplastics designed specifically to attenuate sound, ideal for noisy environments such as concerts or building sites. Custom earplugs are otoplastics, but not all otoplastics are earplugs for noise.
Proper care is essential to keep your custom-made earplugs in good condition. We supply all our fitted earplugs with a handy storage case. Always use this case whenever you are not wearing the earplugs, so you do not lose them and they stay protected from dirt and damage. Need extra cleaning wipes? You can pick these up from us free of charge.
With us, otoplastics start from € 119. The price for custom-made earplugs at Audinc depends on the type of earplugs you choose and any additional wishes or adjustments. Our prices are transparent and you can easily find them listed with the various earplugs in our range.
For high-quality custom-made earplugs, you can visit one of the Audinc service points. We have several service points, so there is always a location near you. Our expert staff make sure your earplugs fit perfectly and fully meet your needs.
Absolutely, Audinc also offers custom hearing protection for companies. This can be essential in environments with a lot of noise, such as construction or industrial workplaces. For more information, see the workplace hearing protection page, where you will find more details.
Custom-made earplugs always provide better sound attenuation than universal earplugs. They are shaped specifically to your ear canal, so no sound can leak past. The fit not only adds extra comfort but also makes the earplugs considerably more effective at attenuating sound.
Custom hearing protection lasts for years. At Audinc we always offer a minimum 2-year warranty on our earplugs, plus a 100% comfort guarantee. So you can count on your earplugs staying comfortable and fitting well for a long time. Because your ears can change over time, you are always welcome for a fit test and any adjustments.
