10 Pairs Soft Foam Earplugs
This pack contains ten pairs of disposable foam earplugs rated at 30 NRR. The self-adjusting material expands to fit a wide range of ear canals for reliable noise reduction. Vibrant yellow and magenta colours keep the protection visible in busy environments. They are suited for sleeping, study sessions, loud events and work with power tools.
Replaces single-use wax or silicone plugs
Foam expands more evenly than mouldable wax, giving a consistent seal without the sticky residue. The contoured T-shape removes the guesswork of rolling a cylinder between fingers before insertion. Switching is worth it when you need faster fitting for repeated short-term use or when bright colours are required for compliance checks. They do not suit buyers who need a corded design to prevent loss between uses.
Insert by rolling and holding
Roll the tip tightly, insert, then hold for a few seconds while the foam rebounds to fill the canal. The smooth closed-cell skin resists dirt build-up during extended wear. A common issue is rolling the plug too loosely, which prevents full expansion and lowers attenuation. The short 1.18in cord stub is not designed for tethering, so users who need a connecting cord should look elsewhere.

Questions about this item
What size ear canal do the 1.18 in foam tips expand to fit?
The self-adjusting foam expands to fit virtually any ear canal diameter for a secure seal.
How do I insert the contoured T-shape plugs without pushing them too deep?
Roll each plug between fingers, pull the ear up and back, then slide the T-shape in until it sits flush — do not force past the flange.
When should I replace the 10 pairs of disposable foam plugs?
Replace a pair when the foam no longer fully rebounds, the skin feels tacky, or after a single use in dirty environments.
