Bouchon anti-bruit alvis Mk3

In the opinion of journalists and professionals who have tested it, it is the best hearing protection available: It was designed for extreme uses, to protect your hearing without cutting you off the world! 

The difference with respect to a usual stopper comes from the progressivity of the attenuation: low protection in quiet (4dB to 80dB of noise), moderate attenuation in average noise (24dB to 100dB), high attenuation in high noise (39 dB to 120 dB), All sounds remain clear and precise, but they are compressed to a comfortable and harmless level, 

Advantage Mk3: comfort and acoustic precision, 

Advantage Mk4: enhanced attenuation on acute frequencies (the most risky). 

Advantage Mk5: A very strong attenuation of the intense noises.

Mode d'emploi

Operating instructions Alvis Mk3 and Mk4


The Red headset for the right ear, the white headset for left ear.
Introduce the hearing CAP in the ear by pressing the round part (red or white) without hesitation. You can rotate by a quarter turn by pressing the CAP so that it is firmly in place. The CAP must ensure a perfect seal. If it is not well implemented, hearing mitigation will lose much of its effectiveness.


The half-moon part that remains in the conch of the ear (helix) can be cut to fit your ear. This part of the CAP has no effect on mitigation hearing, its function is to ensure both comfort and support.

Test before use:

To make sure that the seal is perfect, click in your hands close to your ears. A snap of hand generates very significant noise and must be substantially mitigated. If it is not attenuated, the implemented needs to be adjusted.


Clean your corks Alvis with SOAP and water, or with a spray device auditory (AudioBox preferred brand). Let dry your Alvis in the open air, then store them in their box sealed.To ensure a long lifetime of your Alvis, you can regularly clean with wipes lubricated for hearing device (ALVIS Pure).

Use of the closed valve, the 2 in 1 function:

Open position. You get a gradual attenuation of noise to hear in quiet all in being protected in the noise. Closed position. Mitigation is permanent, like a cork Occlusive. This position is useful for sound exhibitions, intense and prolonged, to cut the noise of funds or light (plane, sleep...) or for swimming.
