The Importance of Slow Rebound

The quality of an earplug is determined by its ability to slowly recover its original shape. This characteristic allows the earplug to gradually conform to the ear canal, ensuring comfort and long-term protection without causing damage:

• Expansion time: A high-quality earplug should take between 20 and 50 seconds to fully expand inside the ear.

• Importance of slow rebound: Provides sufficient time to insert the earplug deeply before it returns to its original size.

• Body temperature: The heat inside the ear helps the foam expand and perfectly adapt to the shape of the ear canal.

Insertion Instructions (Step by Step)

1. Roll: Roll the earplug between your fingers into a small, smooth cylinder without creases.*

2. Insert: Insert the compressed cylinder into the ear canal as shown in the illustration.

3. Hold: Keep the earplug in place with your finger until it fully expands.

4. Check fit: Ensure a proper seal to guarantee effective noise attenuation.

* Note: Do not flatten or crush the earplug, as this damages the internal foam cell structure and prevents proper recovery of its original shape.
