Purpose and Audience

Flents 70121 foam ear plugs deliver a laboratory-tested NRR of 33 dB for anyone who needs disposable hearing protection. The 70-pair pack suits workers on construction sites, around heavy machinery, or in loud workshops, as well as commuters, students and travellers seeking quieter surroundings for focus or rest.

Capacity and Headroom

Each pair provides up to 33 decibels of attenuation under controlled conditions; real-world reduction varies with fit, ear anatomy and activity level. The soft slow-recovery foam compresses to a thin cylinder and expands to seal the ear canal, but protection drops sharply if insertion is incomplete or the plug shifts during movement.

Bundled Extras

The single pack contains 70 purple pairs intended for hygienic single use, eliminating the need for cleaning or storage between sessions. No cord, case, carrying pouch or application tool is included, so users must supply their own storage and remember the recommended 30-second hold while the foam expands.

Questions about this item

Will the 33 dB NRR foam plugs still seal properly if I wear them over my existing hearing-aid tubing?

The plugs are designed to expand inside the ear canal; any tubing or device that prevents a full seal will lower the actual attenuation below the rated 33 dB.

How can I confirm the 70121 plugs are expanding correctly after insertion?

Hold each plug in place for about 30 seconds while the foam recovers; a proper seal feels snug and noticeably muffles surrounding noise.

Does the 70-pair pack include a carrying case or must I buy one separately?

The pack contains only the 70 pairs of purple foam plugs; no case or accessories are included.
