I know that hearing protection is now a bit longer. Oppressive even with long wearing time or it does not itch and it forms no sweat.
The foam is compressed, inserted into the ear canal, after a few seconds "pump" the foam and thus gently closes any loopholes that would again allow the intrusion of noise.
There are the BILSOM 303 in the Large or Small variant. Which one is best suited for you, you can only try heruasfinden or through experience with other ear plugs.
However, the foam is flexible and gentle he is unlikely to press - but the hearing protection falls too large can be made of the import is not deep enough in the ear.
The delivery by Aposparer was super fast - ordered Wednesday, Friday arrived - what more could you want? I would not hesitate to order again at Aposparer.
