Advice on adaptation

During first-time use, it is recommended to have them worn gradually: 2 hours at the end of a shift on the first days, followed by a steady increase in wearing time.
Two to three weeks are sufficient for complete adaptation.

Some people may feel concerned during the first few uses:

• an internal echo effect,
• a feeling of moving around in a soundproofed chamber,
• discomfort in the area of the ear,
• an impression of hearing too much of the voice or not enough of the noise of the machines...

These sensations, which are a sign that the protection is properly airtight in the ear, are temporary and will fade with time.
