Foam earplugs
ear protection
Cut down on noise from your surroundings without cutting yourself off from the world! Quies foam earplugs reduce loud noise by 35 dB.
The anatomically-friendly design fits snugly inside your ear for a tight fit and effective noise protection. The soft, smooth, and flexible foam ensures added comfort.
With three complementary bright colours and more natural flesh tone to choose from, there’s something for everybody!
Material: Polyurethane foam.
Meets CEN (European Committee for Standardization) standard EN 352-2 for hearing protection devices.

- Recommendations
- Noise attenuation table
While sleeping: use at home and on the go.
At work or while studying: improve concentration in noisy environments.
For music or loud noise: enjoy concerts safely, protect your ears when using heavy machinery, and stay safe during outdoor activities like hunting and motorsports.
In the cold: protect your ears from low temperatures.
- Roll the earplug between your fingers to compress it.
- Pull your earlobe back and up slightly to insert the earplug.
- While continuing to pull back your earlobe, insert the compressed earplug and hold it in place. Wait for the earplug to expand to the shape of your ear, then release.
Clean the earplugs with warm, soapy water after each use.
Use only if your ears are clean and healthy.
Keep your earplugs in their case and store in a cool, dry place
| SNR | (Single Number Rating) | 35 |
|---|---|---|
| H | (High Level) | 34 |
| M | (Medium Level) | 32 |
| L | (Low Level) | 31 |
First table:
- SNR is the Single Number Rating system used to rate overall noise attenuation properties; it is the average of all other measurements combined.
- H, M, and L stand for High, Medium, and Low frequencies.
The numbers 34, 32, and 31 denote the average noise attenuation in decibels for the high, medium, and low frequencies, respectively.
| Frequency (Hz) | 125 | 250 | 500 | 1000 | 2000 | 4000 | 8000 |
|---|---|---|---|---|---|---|---|
| Average attenuation (dB) | 36.0 | 36.7 | 39 | 36 | 37 | 46.7 | 44.6 |
| Standard deviation (dB) | 6.0 | 6.1 | 6.5 | 5.9 | 4.9 | 3.2 | 3.8 |
| APV (dB) | 30 | 30.6 | 32.5 | 30.1 | 32.1 | 43.5 | 40.8 |
Second table:
- Frequencies stated in Hertz (Hz): 7 frequencies tested (from 125 to 8,000 Hz)
- Noise attenuation stated in decibels (dB): For example, for a frequency of 125 Hz, noise is reduced by 36 dB.
- Standard deviation in decibels (dB): The difference between average noise attenuation and APV.
- APV, or Assumed Protection Value, in decibels (dB): Indicates noise attenuation quality. It is calculated mathematically.
The figures presented in these tables were obtained from tests run by the French National Institute for Research and Safety (INRS) according to CEN standard EN 352-2: 2002, which sets forth noise protection device standards and the testing methods used to check compliance with these standards.
