Moldex MX-5 Over-The-Head Earmuffs

Moldex MX-5 Over-The-Head Earmuffs — Review

The Moldex MX-5 is an overhead earmuff from Moldex's MX-series industrial hearing protector line. It is positioned for manufacturing floors, assembly operations, and light-to-moderate construction environments where workers wear hearing protection for full shifts rather than intermittent high-noise tasks. Moldex designs the MX-series for extended daily use: the ear cushions use a soft foam-filled design that conforms to varied face profiles without requiring specific headband tightening, and the headband arc adjusts to head sizes across a typical crew range without size-specific variants.

The MX-5 is ANSI S3.19 certified, meeting OSHA requirements for inclusion in formal hearing conservation programs under 29 CFR 1910.95. The green-and-black Moldex color scheme is consistent with the MX-series family, making it easy to identify as part of a standardized Moldex PPE program.

MX-Series Positioning

The Moldex MX-series spans several attenuation levels for different noise environments. The MX-5 targets mid-level industrial applications — adequate for most manufacturing and assembly environments without the additional bulk of maximum-attenuation earmuffs. For environments with higher sustained noise levels, the MX-6 offers increased attenuation in the same platform.

Strengths and Limitations

Strengths: ANSI S3.19 certified; soft foam-filled cushions for extended-shift comfort; adjustable headband accommodates broad head size range; Moldex-quality construction known for long cushion life; no batteries required — passive protection; compatible with supplemental hearing protection (foam earplugs) for noisier environments.

Limitations: passive design reduces all sound including speech — communication requires earmuff removal or a separate communication system; attenuation may be insufficient as a standalone protector for very high-noise environments without doubling; green-and-black colorway is not hi-vis.

Frequently Asked Questions

What environments is the MX-5 designed for?

The MX-5 targets manufacturing, assembly, light construction, and similar environments with moderate sustained noise levels. It is engineered for full-shift daily use rather than intermittent or occasional high-noise tasks. For very high-noise environments (above 100 dB TWA), evaluate the MX-6 or a combination of earmuffs and earplugs.

How does the MX-5 compare to the MX-6?

Both are passive overhead earmuffs in the Moldex MX-series using the same platform and headband design. The MX-6 provides a higher attenuation rating for noisier environments. If your facility's noise assessment places TWA exposures in the moderate range, the MX-5 is the appropriate selection; for higher exposures, step up to the MX-6 and verify the derated NRR covers your measured exposure levels.

Are Moldex ear cushions replaceable?

Yes. Moldex produces replacement ear cushions for the MX-series, allowing the headband assembly to be reused after cushion wear — reducing long-term per-unit cost in high-use environments. Replacement cushions are the primary maintenance item for any foam-cushion earmuff.

Is the MX-5 compatible with double protection?

Yes. When workplace noise exposure exceeds what the MX-5 alone can address at the derated NRR level, wearing foam earplugs underneath adds additional attenuation. The combined NRR for double protection is calculated using OSHA guidelines — not simply additive. Consult your industrial hygienist for the correct combination NRR for your exposure levels.
