Howard Leight X-TREME XTR-1 NRR 32 Foam Ear Plugs (Uncorded, Disposable) Overview
The Howard Leight X-TREME XTR-1 is a disposable, uncorded polyurethane foam roll-down ear plug carrying a laboratory Noise Reduction Rating (NRR) of 32 dB under ANSI S3.19. It sits at the top of the foam-plug range, making it a high-attenuation choice for crews running heavy equipment, grinding, stamping, or any operation where measured exposure climbs toward or past the OSHA limits. As a single-use plug, the XTR-1 is the right pick when fresh, hygienic protection every shift matters more than reusability.
Be honest about real-world protection. The NRR 32 on the box is a laboratory number; the attenuation you actually get on the floor is lower and depends entirely on a correct roll-down-and-insert. OSHA's derating method estimates field protection as (NRR − 7) ÷ 2, which for this plug is roughly 12.5 dB. NIOSH instead recommends derating foam plugs by 25%, giving an estimated 24 dB. Either way, use the derated figure when you build your hearing-conservation math, not the printed 32. Under OSHA 1910.95 hearing conservation, the 85 dBA 8-hour action level triggers a program (monitoring, audiometric testing, protection), and 90 dBA is the permissible exposure limit (PEL). New to the rating? See what is NRR and how to calculate the NRR you need before you buy.
The XTR-1 is part of WC Safety's wider foam ear plugs and hearing protection range, alongside disposable ear plugs for single-use programs. For a step-by-step fit, follow how to insert foam earplugs — with foam, fit technique drives almost all of the real attenuation.
What It Is Built For
| Use case | Fit | Buyer guidance |
|---|---|---|
| High-noise grinding, stamping, or heavy equipment | Strong fit | NRR 32 is among the highest foam ratings; ideal where measured exposure is at or above the 90 dBA OSHA PEL. |
| Single-use / disposable hygiene program | Strong fit | Fresh polyurethane plug every shift; no cleaning or storage. Pair with a dispenser for high-traffic areas. |
| Moderate noise (85-90 dBA action-level work) | Good fit, may over-protect | Provides ample margin; if workers need to hear alarms or speech, a lower-NRR plug can prevent over-attenuation. |
| All-day wear comfort in warm plants | Good fit | Soft self-expanding foam suits long shifts; insert with clean, dry hands to preserve attenuation. |
| Repeated remove/replace work (lifting plugs in and out) | Limited fit | Uncorded plugs are easy to drop or lose; a corded or banded plug is better for frequent on/off cycles. |
| Dusty or wet hands on the line | Limited fit | Contaminated foam degrades the seal and hygiene; swap to a fresh pair rather than reinserting a soiled plug. |
Earplugs reduce noise, but the labeled NRR is a laboratory number — real-world protection is lower. NIOSH derates foam by about 25%, and OSHA estimates protection as (NRR − 7) ÷ 2. Under OSHA 29 CFR 1910.95 a hearing-conservation program is required at an 8-hour TWA of 85 dBA. Insert foam plugs correctly (roll, pull the ear up and back, hold) for the rated seal, and use dual protection with earmuffs in very high noise. See how to calculate the NRR you need.
Pros & Cons
Pros
- NRR 32 (ANSI S3.19) — among the highest ratings available in a disposable foam plug
- Single-use polyurethane: fresh, hygienic protection every shift with no cleaning
- Soft self-expanding foam suited to all-day industrial wear
- High attenuation margin for work at or above the 90 dBA OSHA PEL
- Uncorded design keeps the plug clear of moving equipment and snag points
- Sold in bulk pairs for cost-effective fleet or dispenser stocking
Cons
- Real-world protection is far below the label — OSHA derate ~12.5 dB, NIOSH ~24 dB; fit technique is critical
- Uncorded plugs are easy to drop or lose during frequent remove/replace cycles
- Single-use only — not reusable, so per-use cost is higher than a washable flanged plug
- Can over-protect in moderate noise, making alarms and speech harder to hear
How It Compares
Within Howard Leight's disposable cordless foam range, the X-TREME XTR-1 (NRR 32) sits at the top of the attenuation ladder. The Maximum Lite (LPF-1) and FirmFit (FF-1) are both rated NRR 30 — a step down in laboratory rating but still high-attenuation single-use foam. If you need a washable, reusable alternative rather than a disposable plug, the flanged TRUSTFIT (NRR 28) and Quiet QD1 (NRR 26) trade some rating for reuse. For the very highest foam ratings on the market, NRR 33 options live in our NRR 33 ear plugs collection, and you can browse alternatives like the Moldex Softies uncorded foam ear plugs (NRR 33). Remember the 2-point spread between an NRR 30 and NRR 32 plug is small after derating — fit quality matters far more than the label gap. For reusable options, see our reusable ear plugs range.

Frequently Asked Questions
What is the NRR of the Howard Leight X-TREME XTR-1?
The XTR-1 is rated NRR 32 dB under ANSI S3.19. That is a laboratory number; see the derating questions below for the protection you can realistically expect on the job.
How much noise reduction will I actually get from an NRR 32 plug?
Less than 32 dB. OSHA's method estimates field protection as (NRR-7)/2, which is about 12.5 dB for this plug. NIOSH recommends derating foam plugs 25%, giving roughly 24 dB. Use the derated number for your hearing-conservation math, and review our guide on how to calculate the NRR you need.
Are the X-TREME XTR-1 earplugs corded or uncorded?
They are uncorded (cordless). This keeps the plug clear of moving equipment, but uncorded plugs are easier to drop or lose during frequent remove-and-replace work. If you need a cord, browse our corded ear plugs collection.
Are the XTR-1 plugs reusable or single-use?
They are single-use, disposable polyurethane foam plugs. Use a fresh pair each shift rather than cleaning and reinserting. If you want a washable, reusable plug instead, see our reusable ear plugs.
What is the XTR-1 made of and what form factor is it?
It is a self-expanding polyurethane foam roll-down plug. You roll it down between your fingers, insert it, and let it expand to seal the ear canal. Step-by-step fit instructions are in our guide on how to insert foam earplugs.
Is NRR 32 high enough for my workplace?
It is among the highest foam ratings available, well suited to work at or above the 90 dBA OSHA PEL. Whether it is enough depends on your measured exposure minus the derated attenuation. Our guide on how to calculate the NRR you need walks through the math.
How does the XTR-1 compare to the Howard Leight Maximum Lite or FirmFit?
The XTR-1 is NRR 32, while the Maximum Lite (LPF-1) and FirmFit (FF-1) are both NRR 30. All three are disposable cordless foam plugs. After derating, the 2-point gap is small, so choose based on comfort, fit, and price as much as the rating.
Can NRR 32 plugs over-protect me?
Yes. In moderate noise around the 85-90 dBA range, a very high NRR can make it harder to hear alarms, machinery cues, and speech. If that is a concern, a lower-NRR plug may be a better balance. See ear plugs vs ear muffs for choosing the right level.
How do I get the rated protection from these plugs?
Foam attenuation depends almost entirely on insertion. Roll the plug down tightly, pull the ear up and back, insert deeply, and hold while it expands. A shallow or rushed fit can cost you 10 dB or more. Follow how to insert foam earplugs every time.
What does OSHA require for hearing protection at my noise level?
Under OSHA 1910.95, an 8-hour exposure at or above the 85 dBA action level triggers a hearing conservation program, and 90 dBA is the permissible exposure limit. Read our overview of OSHA 1910.95 hearing conservation for the full requirements.
How many pairs come in a box, and how should I stock them?
The XTR-1 is sold in bulk pairs suited to dispensers and fleet stocking; current pack quantity and pricing are shown on the Amazon listing. Because they are single-use, plan one fresh pair per worker per shift. Browse the full disposable ear plugs range to compare pack sizes.
What if I need an even higher rating than NRR 32?
NRR 33 is the highest foam rating commonly available. See our NRR 33 ear plugs collection or pair plugs with ear muffs for dual protection; our ear plugs vs ear muffs guide explains how combined ratings work.

Walgreens used to carry these, but they changed manufacturers
These are the ones that actually stop noise. I couldn't figure out why the Walgreens brand wasn't working any longer until I compared the label from the old and the new bottle. They changed manufacturers. These are comfortable and do a good job at reducing noise.
