Key Features

High-Quality Silicone Material

Silicone material gradually adapts to the ear canal shape using body temperature for a perfect fit.

Christmas Tree Three-Layer Skirt Design

Three-layer skirt structure provides excellent sealing, effectively blocking noise from entering the ear canal.

Ergonomic Handle Design

Handle design follows ergonomic principles, making insertion and removal easy without the need for rolling.

No Rolling Required, Easy to Use

Unlike PU earplugs, silicone earplugs do not need to be rolled before insertion, saving operation time.

Easy-Break Cord Design (FH0304)

The with-cord model features an easy-break cord design that helps prevent tangling and reduces the risk of losing earplugs.

Frequently Asked Questions

Q: What is the difference between silicone and PU earplugs?

A: PU earplugs need to be rolled thin before expanding to fit the ear canal, offering high softness for extended wear. Silicone earplugs require no rolling - just insert directly - and can be washed for reuse (though regular replacement is recommended), making them more suitable for frequent removal or high-hygiene situations.

Q: How to choose between FH0303 and FH0304?

A: If your job requires frequent earplug removal for communication, choose FH0304 with cord to prevent loss. For jobs with low removal frequency, FH0303 without cord offers better cost-effectiveness.

Q: Can silicone earplugs be washed?

A: Yes. Silicone earplugs can be rinsed with clean water and reused after drying. However, regularly check for damage or deformation and replace when necessary.

Q: How should they be fitted?

A: Reach over your head with one hand to pull the ear up and back, use the other hand to hold the handle and gently insert the earplug into the ear canal. Adjust until it feels sealed and comfortable. All three skirt layers should be inside the ear canal.
