Howard Leight smf-30 Smartfit Reusable Earplugs

Product Description

The HOWARD LEIGHT smf-30 SmartFit earplugs are reusable hearing protection designed for repeated use in industrial, construction, and trade environments. These earplugs use Conforming Material Technology, which harnesses body heat to mold the triple-flange design to the individual shape of the ear canal. This adaptive fit helps reduce the risk of improper insertion and inconsistent noise attenuation. The smf-30 comes with a HearPack storage case and a detachable cord, making them practical for technicians, mechanics, and tradespeople who remove and reinsert hearing protection throughout a shift.

The smf-30 is suited for use in loud mechanical rooms, shop floors, rooftop HVAC work, and similar environments where sustained noise exposure is a concern. The detachable cord keeps the earplugs accessible when not in use and reduces the chance of loss in the field. The included HearPack storage case protects the earplugs between uses and helps maintain hygiene. These are appropriate for any trade professional required by OSHA hearing conservation programs to wear hearing protection in high-decibel work zones.

Key Features

• Conforming Material Technology uses body heat to adapt triple-flange shape to the ear canal for a consistent fit
• Reusable design reduces per-use cost compared to disposable foam plugs
• Detachable cord keeps earplugs accessible during intermittent-use tasks
• Includes HearPack storage case for field hygiene and protection between uses
• Tested to ANSI S3.19-1974 for noise attenuation performance

Compatibility

Designed as a general-purpose reusable earplug for trade and industrial hearing protection programs requiring ANSI-tested attenuation performance.

Installation Notes

Pull the upper ear back and upward before inserting the earplug to straighten the ear canal and allow full seating of the triple-flange tip. Allow a brief moment for the Conforming Material Technology to respond to body heat and form to the canal shape before exposure to loud environments. Clean the earplugs with mild soap and water and store them in the included HearPack case when not in use. Replace when flanges show visible deformation, cracking, or loss of flexibility.
