Howard Leight FirmFit FF-1 Earplugs, NRR 30 Cordless Foam (Firm PVC) Overview
The Howard Leight FirmFit FF-1 earplugs are uncorded, single-use foam hearing protection rated NRR 30 in the US, built around a firm PVC foam that inserts cleanly. Under OSHA 1910.95, hearing protection is required when noise reaches an 8-hour time-weighted average of 85 dBA, and a well-fitted foam plug like this is a practical first line of defense for high-noise work.
As firm foam earplugs, the FF-1's design targets easy, consistent insertion: the cylindrical PVC foam needs less pressure to roll down and has a slow recovery rate, so you have time to seat it before it expands. As slow-recovery foam earplugs Howard Leight lists it as about 40% softer with 29% lower expansion pressure than the leading classic-style plug, and the warning orange color makes compliance checks easy. This is the FirmFit NRR 30 plug in its uncorded form.
Like any item in hearing protection, match the plug to your measured noise exposure rather than reaching for the highest number. As uncorded plugs the Howard Leight FF-1 avoids a cord that could snag; the same FirmFit plug is sold corded as the FF-30. Compare these disposable foam earplugs against other foam and NRR 30 options, and note the orange makes them one of the high-visibility ear plugs before ordering.
What These FirmFit Earplugs Are Built For
| Use case | Fit | Buyer guidance |
|---|---|---|
| High-noise industrial work | Purpose-built | NRR 30 covers most workplace noise when fitted correctly. |
| Workers who struggle to insert foam | Strong | Firmer foam and slow recovery make seating the plug easier. |
| Long shifts / comfort | Strong | Lower expansion pressure than a classic plug reduces the plugged feeling. |
| Compliance-check visibility | Strong | Warning orange makes correct insertion easy to confirm at a distance. |
| Repeated all-day reuse | Not ideal | Single-use; for daily reuse choose a washable reusable earplug. |
Hearing protection only works when it fits. The labeled NRR is a laboratory value that overstates real-world attenuation, so OSHA and NIOSH recommend derating it β a common method subtracts 7 from the NRR and halves the remainder when estimating protection against a time-weighted average exposure. Wear hearing protection whenever noise reaches an 8-hour TWA of 85 dBA under OSHA 1910.95, roll and insert each foam plug fully and hold until it expands, replace plugs that will not seal, and use dual protection (plugs plus muffs) only per your safety program for very high noise.

Pros & Cons
- High NRR 30 for a disposable foam earplug
- Firm PVC foam and slow recovery for easier, cleaner insertion
- Lower expansion pressure than a classic plug for comfort
- Warning orange for compliance checks
- Uncorded to avoid snags (corded FF-30 also available)
- Single-use β not a washable reusable plug
- Uncorded β easier to drop than the corded FF-30
- Field attenuation depends on fit; derate the labeled NRR
- Firmer feel than a low-pressure foam for some wearers
How It Compares
The FirmFit FF-1 is the firm PVC-foam, uncorded NRR 30 disposable. Weigh it against the alternatives before ordering:
| Option | Foam | NRR | Best for |
|---|---|---|---|
| FirmFit FF-1 (this page) | Firm PVC, slow-recovery | 30 | Easier, cleaner insertion |
| FirmFit FF-30 (corded) | Firm PVC, slow-recovery | 30 | Preventing dropped plugs |
| Low-pressure PU foam plug | Soft polyurethane | 30-32 | Softest all-day feel |
Choose the FirmFit FF-1 for firm, easy-to-insert foam, the corded FF-30 to avoid drops, or a low-pressure foam plug for the softest feel. Compare in our best foam ear plugs guide and the wider hearing protection range.

Frequently Asked Questions
What is the NRR of the Howard Leight FirmFit FF-1?
The FirmFit FF-1 is rated NRR 30 in the US, strong protection for medium-to-high noise. NRR is a laboratory value, so derate it for real-world use rather than assuming full protection. It suits most industrial noise when fitted correctly.
Are the FirmFit FF-1 corded or uncorded?
This FF-1 listing is the uncorded (cordless) version. Howard Leight sells the same FirmFit plug corded as the FF-30 for applications where a neck cord helps prevent dropping. Choose uncorded where a cord could snag on moving equipment.
What does firm foam mean on the FirmFit?
The FirmFit uses a firm PVC foam in a cylindrical shape. The firmness helps the rolled plug hold its shape long enough to insert cleanly, and a slow recovery rate gives you time to seat it before it expands. It still targets comfort with lower expansion pressure than a classic plug.
Is the FirmFit comfortable despite being firm?
Howard Leight lists the FirmFit as about 40% softer with 29% lower expansion pressure on the ear canal than the leading classic-style earplug, so the firm reference is about insertion behavior, not a hard feel. The lower pressure aims at all-day comfort.
What color are they and why?
A warning orange color, which makes it easy for a supervisor to confirm at a glance that a worker has the plugs inserted. Bright colors support hearing-protection compliance checks on a busy site.
What are the earplugs made of?
A firm PVC foam, which differs from the polyurethane foam used in some other disposable plugs. The foam compresses for insertion and expands to seal the canal. The plug is single-use and disposable.
How do I insert the FF-1 correctly?
Roll the foam down to a thin crease with clean fingers, reach over your head to pull the ear up and back, insert the plug well into the canal, and hold it while the foam expands. The slow recovery gives you time; if you can still hear normally, reinsert.
How should I apply the NRR to real noise levels?
OSHA and NIOSH recommend derating the labeled NRR because lab conditions overstate field performance. A common OSHA method subtracts 7 from the NRR and halves the remainder when estimating protection against a time-weighted average exposure. Follow your safety program's method.
When is hearing protection required?
OSHA requires hearing protection when noise reaches or exceeds an 8-hour time-weighted average of 85 dBA under 1910.95. If you must raise your voice to be heard at arm's length, noise is likely high enough to warrant protection. See our guide on when hearing protection is needed.
Can I use these with earmuffs for very loud work?
Yes. Dual protection - earplugs plus earmuffs - is used for very high noise, but the combined NRR is not the sum of the two. Add about 5 dB to the higher of the two device ratings as a rule of thumb, and follow your safety program for dual-protection thresholds.
Are the FirmFit FF-1 reusable?
They are single-use disposable plugs. You can reuse a pair briefly if they stay clean and keep their shape, but discard them once they are dirty, will not expand, or no longer seal. For repeated daily wear, a washable reusable earplug is a better fit.
How are the FF-1 earplugs packaged?
The FirmFit FF-1 is sold in polybag or paper-bag packs, commonly in 200-pair boxes, and in dispenser refills for the Leight Source 500. Check the packaging for the exact count and choose the pack that matches how you issue and replace plugs.
