Single-Use Foam Earplugs

Moldex SparkPlugs 507-6604 are disposable foam earplugs rated at 33 NRR for high-noise environments. Each bulk bag contains 200 wrapped pairs in assorted multicolor patterns. They suit industrial workers, contractors and DIY users who need reliable single-use hearing protection without cords.

Roll-Down Insertion Method

Compress the bullet-shaped foam plug between fingers, insert into the ear canal and hold until it expands to seal. The uncorded design eliminates tangling but requires careful storage to avoid losing individual plugs. Foam degrades with moisture or repeated handling so each pair is intended for one shift only.

33 NRR to ANSI S3.19-1974

The decisive specification is the Noise Reduction Rating of 33 dB tested under ANSI S3.19-1974. This level addresses very loud continuous noise such as heavy machinery or power tools. Buyers needing lower attenuation for communication clarity or reusable plugs for multi-day use should select a different product.

Questions about this item

How can I confirm the earplugs are sealing properly after rolling them down?

A correct roll-down fit reduces outside sound noticeably; the 33 NRR rating means the plug is tested to that attenuation when inserted fully into the ear canal.

What comes inside the bulk bag and do I need any extra accessories?

The bag contains 200 individually wrapped pairs of cordless foam plugs; no cords, cases or dispensers are included and none are required for use.

Which pack size should I choose for a team that goes through several pairs each shift?

This single SKU provides 200 pairs in one bulk bag, designed for high-turnover environments where workers grab a fresh wrapped pair every time.
