⚡ At a Glance
- • Wearing Comfort: Tapered, lightweight PU foam compresses and expands to mould securely to ear canals
- • Best for: Light sleepers, travellers and people needing short-term protection against loud noises
- • Not ideal for: Users who need reusable custom-moulded or electronic hearing protection solutions
A dense PU foam earplug with a 38dB SNR rating designed to reduce a wide range of background noises. Each pack contains 60 pairs plus a screw-sealed keychain case for portable storage.
Quieter Nights – Thanks to 38dB SNR noise reduction
A 38dB SNR rating indicates significant attenuation of ambient and sudden loud sounds, achieved by dense foam that absorbs and blocks sound waves. The tapered profile helps form a reliable seal in the ear canal.
Noticeably lower background noise helps users sleep and study with fewer interruptions, including traffic, noisy neighbours and home appliances.
All-night Comfort – With tapered, non-toxic PU foam
Lightweight, non-toxic PU material compresses on insertion then expands gently to fill the ear canal, while the tapered design reduces pressure points. The material is described as soft yet dense for a balance of comfort and attenuation.
Comfortable for extended wear and moulds to different ear shapes, making overnight use more realistic than standard rigid plugs.
Hygienic Portability – With screw-sealed keychain travel case
A compact travel case closes with a screw-seal that limits exposure to moisture, dust and debris during transport. The keychain format keeps spares on hand for travel or work.
Easy to carry and keeps pairs clean between uses, so spares remain hygienic when packed in a bag or pocket.
