Frequently Asked Questions

EAROS Products

How does EAROS high-fidelity hearing protection work?

Our proprietary, patented sound bore replicates how the inner ear resonates while providing 17+ dB of noise reduction and preserving full audio fidelity.

We worked with top audiologists and vibration engineers from MIT to
develop EAROS' patented technology

How are EAROS acoustic filters different from "earplugs"?

1) Sound Quality: Foam earplugs muffle and distort sound. EAROS acoustic filters maintain sound quality, allowing you to enjoy music, communicate with those around you and stay immersed in the sound.

2) Protection: While foam earplugs often have a high NRR rating, they can be quite difficult to insert properly, resulting in less protection than advertised. EAROS has a unique “concha tab” that locks in place, ensuring proper depth of insertion so you can count on getting the seal you need for the product to be effective.

3) Comfort: Foam earplugs are difficult to insert and have a high “occlusion effect” (feeling like you’re underwater). EAROS have a left-right orientation and are contoured to fit the shape of your ears comfortably. We use a soft, silicone-like material for the ear tips to ensure there is no irritation even for extended uses.

4) Style: Foam earplugs stick out of your ears and are goofy-looking, compromising your personal style.  EAROS is a sleek, discreet product that looks more like a high-tech wearable than traditional hearing protection so you can be proud to be seen wearing it.

5) Sustainability: Earplugs are a single-use, disposable product that damages the environment every time you buy another pair. In fact, billions are produced and thrown away each year. EAROS, on the other hand, is a high-quality, durable, and reusable product that comes with a carrying pouch so you can reuse it many times over and help the environment.

Bottom line, EAROS is not an earplug since it does not block sound, but rather filters out noise. After all, who wants to "plug" their ears while trying to enjoy an immersive sensory experience?

How do I know it will fit my ear?

EAROS is designed to fit most ears and it comes with a set of small, large, and foam ear tips.

If you are having any trouble with your fit, please contact us at We have a 100% satisfaction guaranteed policy and are happy to refund any customer who is not satisfied with the product or fit within a year of purchase.

What ages will EAROS work for?

We don't reccomend EAROS for anyone under 12.

Do they come in different sizes?

Yes! Each pair of EAROS comes with two ear tip sizes, small and large (the small size is affixed when you receive it), and a set of foam tips.

The foam tips do not affect the sound you experience if you use them since they are merely used to hold the EAROS in your ear and form a seal. The foam is available for people whose ear canals are either too small or large for the other tiered tips.

Since the foam is not as durable as the tiered tips, feel free to email us at to send some to you for just the cost of shipping.

Can I order additional ear tips?

Please email us at with any requests for additional ear tip. We are happy to send some for just the cost of shipping until we have it as a product at checkout.

How long do EAROS last?

Ear tips should be changed every 6-12 months depending on wear and tear.
The main body should last around 2 years. We recommend cleaning the
product regularly.

How do I clean my EAROS?

To clean your EAROS, we recommend removing the ear-tip and using a damp cloth or q-tip to clean it, ideally after each use.

Be careful not to submerge them in water as they will not work properly if water enters where the sound goes.

How do I swap out tips?

To remove the small eartip (which is attached to the product when you
receive it) simply hold the "concha tab" (the wing-shaped portion of the
product with the slash mark on it) with one hand, and pull on the
eartip with the other hand, and it should snap right off from the shaft.
Don't worry about pulling too hard -- the product is highly durable so
it won't break. To attach the large eartip, first make sure to identify
the "Left" and "Right" tips, looking for the small "L" and "R" embossed
in black on them. You'll then slide each tip onto the respective "Left"
and "Right" shaft and keep sliding it and twisting it down until the
embossed "L"/"R" on the tip is lined up with the "L"/"R" on the concha

Where are EAROS manufactured?

We manufacture the product at an ISO 9000 Certified facility in the USA
(just outside New York City) using medical-grade materials.

Who are the experts that created EAROS?

Ronnie Madra NYC Nightlife Empressario

Professor Richard H. Lyon Professor Emeritus, MIT Department of Mechanical Engineering and leading expert in acoustics, vibration, and machine dynamics

John Aceti Technologist and engineer

Professor Peter Ragonetti Professor of Industrial Design, Pratt Institute

Dr. Wayne Staab Internationally recognized expert in hearing health

What is NRR and how is it tested?

NRR stands for Noise Reduction Rating. It's a measurement used to assess the effectiveness of hearing protection devices.

The NRR of EAROS was determined through laboratory testing according to ANSI S3.19-1974, standards set by the American National Standards Institute (ANSI), using the experimenter-fit protocol.

Our results are available upon request by emailing us at

Uses & Purposes

Can you still have conversations in these?

Yes indeed! EAROS reduces the noise you experience while still enabling you to hear the sound around you with better clarity than with other hearing protection products.

Are EAROS effective for use at the shooting range?

No. EAROS ONE has a NRR (Noise Reduction Rating) of 17 dB
whereas EAROS SPORT has a NRR of 20 dB. For a loud shooting sports environment, you will likely want to use over-ear protection (i.e., earmuffs) but can be combined with EAROS for extra protection.

Are they waterproof?

No. EAROS acoustic filters are not recommended for showering or
swimming, as they have an opening for sound to pass through which will
not work properly if submerged in water.

Are EAROS good for sleeping in?

While EAROS were not primarily designed for sleeping, we have had many customers use it to dampen noise but still hear an alarm clock while sleeping. EAROS sits flush against your ear making it more comfortable for side sleepers relative to products that stick out. Keep in mind that EAROS was not designed to block out noise completely, so if you want complete silence it’s likely not the best choice.

Are they effective for manufacturing and construction types of work?

Maybe. Please check with your safety manager to confirm that EAROS has enough protection for your specific work environment.

Are they good for singers?

EAROS acoustic filters work better than other hearing protection for
singers, as their design enables less of the "occlusion effect" (booming
sound of your own voice).
