The Howard Leight L2F (R-01525) answers a small, stubborn problem: the hearing protection that stays in the truck protects nobody. It folds a genuine NRR 27 earmuff down to toolbox size — slim low-profile cups, Air Flow Control, telescopic steel-wire headband, snap-in cushions — so the muff that's easy to carry is also the one that's on your head when the saw starts.

Where the Howard Leight L2F fits
Slim earmuffs exist for the worker who moves: between machines, between sites, in and out of noise a dozen times a shift. Fixed-band muffs do the same job but ride around the neck or hang on a hook when not in use; the L2F folds flat instead, which is why it lives in tool bags and glove boxes that full-size muffs never fit. Its low-profile cups also crowd the cheek less under face shields and welding hoods than deep-cup designs. The trade is honest — a folding hinge and slim cups cap out at NRR 27, while the fixed-band Leightning L3 takes the family's top rating for stationary high-noise posts. Our full L2F review digs into the platform, and the passive earmuff roundup ranks it against the field.
Safety first: noise-induced hearing loss is permanent and painless while it happens. The labeled NRR 27 assumes laboratory fit — derate it for real-world attenuation per your hearing conservation program, and remember OSHA 29 CFR 1910.95 starts program duties at an 85 dBA 8-hour average. Anything that breaks the cushion seal — hair, hoods, eyewear temples — costs protection you won't feel losing.
What the listing documents
From the listing: NRR 27 dB; folding, over-the-head design with low-profile slim earcups; patented Air Flow Control for consistent attenuation across frequencies; telescopic steel-wire headband with padded foam; snap-in replaceable ear cushions; model Leightning L2F, part R-01525. That combination — real attenuation in a package that collapses to pocket size — is the entire pitch, and the reason this model outsells fancier muffs with supervisors, inspectors, and service techs who carry their PPE from job to job.
Inside the Leightning and Howard Leight shelf
The family logic is simple: pick your attenuation tier, then pick your band. The L0F is the lighter folding entry point, this L2F is the mid-tier fold, and the L3 is the fixed-band flagship; the L1 covers range duty. Beyond Leightning, Howard Leight's VeriShield VS120FHV is the hi-viz folding alternative and the VS130 pushes to NRR 30 when the survey demands more. Shooters who want amplification should compare the Impact Pro and the electronic-vs-passive decision guide before paying for circuitry they won't use.
Slim ear protection vs the rivals
The L2F's closest cross-brand rival is 3M's Peltor X1A — slimmer rating at NRR 22, similar low-bulk mission — while the 3M folding muff and Radians Terminator undercut it on price at lower ratings. At NRR 27 with replaceable cushions, the L2F generally wins the carry-it-everywhere brief on protection per ounce. Where it loses: all-day fixed stations (get the L3 or VS130) and conversation-heavy ranges (get electronics). The plugs-vs-muffs guide and overall hearing roundup frame the format choice; construction crews have a dedicated pick list.
Ownership and program fit
Wear it right — cups sealed on bare skin, band snug via the correct-wear walkthrough — and maintain it like PPE: swap snap-in cushions when they stiffen, retire the muff when the band loses clamp. Program-side, the NRR explainer and OSHA 1910.95 guide turn the labeled 27 into a defensible assignment against your noise survey. The wider lineup lives in the hearing protection collection, with dedicated shelves for electronic muffs and construction hearing protection. For crew-scale stocking of slim ear protection, quantity orders run through a free Amazon Business account — the walkthrough is linked in our footer.
What the NRR on the box is, and is not
The Noise Reduction Rating is a labelling requirement, not a performance promise. It is mandated by the EPA under 40 CFR Part 211, Subpart B and derived from laboratory testing to ANSI S3.19, on trained subjects under ideal fit conditions.
Attenuation achieved in the field is materially lower, which both regulators acknowledge. OSHA 1910.95 Appendix B converts the rating for A-weighted measurement by subtracting 7, and OSHA separately recommends halving the result as a safety factor; NIOSH derates earmuffs by 25%. At or above an eight-hour TWA of 85 dBA the employer owes a full hearing conservation program — audiometric testing, training and protector choice — not simply a rated product.
Frequently asked questions
What is the Howard Leight L2F?
The folding model of the Leightning L2 slim earmuff: NRR 27 passive hearing protection with low-profile earcups, patented Air Flow Control, a telescopic steel-wire headband, and snap-in replaceable cushions. Part number R-01525.
What does the F in L2F mean in practice?
Folding. The earcups collapse into the headband so the muff stows in a toolbox, glovebox, or coat pocket. Protection specs match the L2 platform — you pay a little more for the hinge and get portability back.
Is NRR 27 enough for my noise level?
Depends on your measured exposure. NRR 27 is strong mid-tier attenuation for an earmuff, but the labeled number assumes laboratory fit — your safety program should derate it for real-world wear before assigning it against a measured dBA. Our NRR guides walk through the math.
How does the L2F differ from the L0F and L3?
Same Leightning family, different attenuation tiers: the L0F is the lighter folding entry model, the L2F sits in the middle at NRR 27, and the L3 is the fixed-band flagship with the family's highest rating. Pick by your noise survey, then by whether you need the fold.
What is Air Flow Control?
Howard Leight's patented earcup design that manages airflow inside the cup to spread attenuation more evenly across frequencies without adding bulk or clamping force — part of how a slim cup reaches NRR 27.
Are the ear cushions replaceable?
Yes — cushions snap in and out. Replace them when they harden, crack, or lose their seal; a worn cushion quietly costs you attenuation. Replacement hygiene kits are the cheap way to double the muff's service life.
Will the L2F fit under a hard hat brim or with safety glasses?
The slim, low-profile cups are the reason to pick this over bulkier muffs for glasses wearers — but any eyewear temple that crosses the cushion seal costs some attenuation. Thin-temple safety glasses minimize the loss.
Is this an electronic earmuff?
No — the L2F is passive. It has no microphones or amplification. If you need to hear range commands or conversation between noise events, compare electronic muffs instead; they cost more and take batteries.
Earmuffs or earplugs for my crew?
Muffs win for intermittent noise (fast on-off, nothing inserted in the canal, easy to supervise); plugs win for all-shift continuous noise, heat, and tight spaces. Many programs stock both and let the noise survey decide.
How should the L2F be worn for full protection?
Cups centered over the ears with the cushion sealing against bare skin all the way around — hair, beanie edges, and glasses temples all leak noise. The telescopic headband adjusts for a snug, even clamp.
When should the whole muff be retired?
When the headband loses clamping force, a cup cracks, or cushions no longer seal after replacement. Any of those quietly ends the NRR. Inspect muffs on the same schedule as the rest of your PPE.

Excellent, Comfortable, Effective, & Inexpensive
The overall quality of these Leightning L3 Earmuffs are EXCELLENT. They are very comfortable to wear for extended periods. They are extremely effective at suppressing loud noise. . . and they are startlingly inexpensive.I've had mine for about a month now, and I use them weekly for shooting firearms. LOUD firearms. . . with several other shooters firing very close to me. Typically I ALWAYS wear BOTH earplugs AND earmuffs when I go shooting. With these, I find that there is little actual difference if I skip wearing earplugs with them.Frankly, I am surprised that there are ANY people on here who gave bad reviews, but I guess there will always be certain people who will find something to complain about. . . even if you gave it to them for free. Listen, I suppose it's possible that there could be better earmuffs out there. . . especially if you have loads of money to burn, and cost is no object. But seriously, for $20, I really think that these are pretty hard to beat. Heck, at ANY price, I think these are pretty hard to beat.** NOTE ** I've read some other buyers complaints that these muffs are not adjustable, and that they were too small to fit their heads and reach their ears. I think that's probably because they couldn't figure out how to adjust them. It took me a few minutes to figure it out myself: The way you adjust them is to pull the metal headband wire out of the black plastic mounting swivels which are mounted on the plastic ear-cups. When the muffs are shipped, they are fully collapsed down to their smallest size, with the metal headband wire pieces pushed all the way down into the black plastic swivels. It's actually a FAR better design than my old earmuffs which adjusted by telescoping the top of the headband instead.Bottom line? Buy 'em & don't look back. I've used alot of earmuffs over the years, and these are the best ones I've had yet.

Hearing pro for the office and outdoors
I picked these up for some quiet in a crowded office with talkative coworkers. Great for blocking out noise! I can still hear muffled voices if I focus on them, but it's much easier to ignore them. They're comfortable to wear, even with blue light, computer glasses. I'll have to see how long I can wear them comfortably, as they are snug. If I had to complain about something, they're rather stiff and tough to adjust. Then, if you fold them up, you have to adjust them to fit your head when you open them again.Amazon suggests that I also mention the fantastic battery life! They last forever on no charge with no batteries, almost like they were passive earmuffs. And they are black, just like the product pictures.

Compact, comfortable, great value, decent NR
These are very nice, affordable, "no frills" earmuffs for the shooting range. They fold up compactly, fit snugly, seal well around the ears, and dampen gunshots to a comfortable level. I particularly like the soft, thin, flexible headband. It feels more comfortable than some of the thicker plastic bands on other earmuffs I've owned. The muffs are reasonably adjustable for different head sizes. In my case, I need them fully extended to fit well. The noise reduction rating is sufficient to reduce gunfire to a comfortable level, yet mild enough that you can still have a conversation with someone without having to raise your voice very much. I think it's a good balance.One (minor) downside is that you can't leave the earmuffs adjusted to the proper length for your head. You have to compress them back down to the shortest setting in order for the earmuffs to fold up inside the headband properly for compact storage. I don't see this as a problem, but some people may find it irritating. Also, I wonder how long the adjustable wires that attach the earmuffs to the headband will last. They don't seem cheap, but they aren't very robust either. I hope they'll hold up well and have no reason to doubt them yet, but they're small enough that I wonder if they may bend or break over time--especially since they need to be adjusted every time I don or stow these earmuffs. For under $20, it's worth the risk.The earmuffs may also interfere with some safety glasses, depending on the thickness and shape of the frames/sides on your glasses. Mine have very flat sides that fit fairly close to my head and run straight back to my ears, so the earmuffs seal fine over them and around my ear. However, if you wear glasses that have flared or curved sides that stand out from the sides of your head a bit, they may not fit well with these earmuffs, or the cups may not seal around your ear properly.

Comfortable & Effective
I compared several ear protectors and this was the best one:Best: Leightning L3 R-03318: Howard Leight R-03318 Leightning L3 Shooter's Premium EarmuffNRR rating 30Attenuation at various frequencies: 34 at 125, 36 at 500, 38 at 1000, 44 at 4000, 45 at 8000Very comfortable, lightweight, fully adjustable without fear of breaking it, padded headband.Muffles office chatter, typing, and lighting or computer humming very well. Does something, but not enough, to block loud mechanical hums and banging.Bottom line: This is my new favorite. It's so comfortable!Acceptable: AO Safety 90559 AO Safety 90559 Folding EarmuffNRR rating 21Attenuation at various frequencies: Don't knowComfortable, lightweight. Plastic unpadded headband adjusts in preset increments, and you have to be gentle when you put it on to avoid breaking it; the plastic broke after a couple years.Reduces the volume of voices but doesn't block them, muffles lighting or computer humming, actually amplifies the sound of typing.Bottom line: Despite its lower NRR rating, I used this one for years and liked it a lot.Uncomfortable: Peltor Optime 105 H10A Peltor H10A Optime 105 Over-the-Head EarmuffNRR rating 30Attenuation at various frequencies: 21 at 125, 37 at 500, 41 at 1000, 43 at 4000, 41 at 8000Uncomfortably tight fit, heavier than the others, padded adjustable headband.Muffles office chatter, typing, and lighting or computer humming well. Does something, but not enough, to block loud mechanical hums and banging. (Same effectiveness as the Leightning)Bottom line: This was effective but so uncomfortable squeezing my head I didn't want to wear it. And I have a small-ish head.Unwearable: Tasco Golden Eagle 2950 Tasco 210-02950 29db Golden Eagle Blk 1pos Ovr-The-Head Earmuff(sold by another vendor as "built to military specifications", no brand name given, at twice the price)NRR rating 29Attenuation at various frequencies: 21 at 125, 36 at 500, 43 at 1000, 37 at 4000, 36 at 8000Very uncomfortable. The adjustable headband looks padded, but in reality there's a piece of unpadded plastic that digs straight into the sides of your head.Did not block sound for me at all, because the earpieces were too big for my head, leaving a gap. Maybe this would fit better on a man with a big head.Bottom line: Hated it.

Good Earmuffs Make All The Difference
I bought these Howard Leight LOF earmuffs after using a cheap pair of another brand for many years. Makes all the difference in the world! These earmuffs are well made and lightweight. They fit my head gently and well. The old ear muffs squeezed my head and ears. Gave me a light headache. No one in my family wanted to wear them.The slim profile of these LOF earmuffs help them to be lightweight and compact and interfere less with the stock when shooting a rifle. If you wear them during outdoor shooting, the lower noise reduction of the earmuffs is fine. However, I recommend using ear plugs with the earmuffs if you are shooting at an indoor range. I bought a pair of Howard Leight L3 earmuffs for use at an indoor range because they have a higher noise reduction rating. They are equally comfortable and tame the harsh noise at an indoor range.The price of the earmuffs is great and Amazon Prime free shipping makes it a great value.I wish I had bought these LOF earmuffs a long time ago... I'll be buying another pair or two in the near future.

Great performance for the price, just know what you are buying and you will be happy
I was looking for a low profile, lightweight, folding compact ear muff to use at the gun range, and low and behold I found it on Amazon.Other reviewers complain that the fit is tight... well yeah it's only common sense that it has a tighter fit because 1) it is lighter than other big heavy ear muffs(like Peltor), and 2) the low profile ear pieces aren't as deep as other ear muffs so it needs to put more pressure on your head so that it seals the sound out effectively. Sure, it doesn't suppress the gun shots as much as the Peltor Ultimate 10 which has a NRR of 30, but what do you expect for having folding earmuffs that weigh 3.2 ounces less(the Peltor Ultimate 10 is 11.2 ounces)?They work fine with my Radians Revelation Protective Shooting Glasses... some other reviewers complain that wearing shooting glasses with these muffs will let sound into the seal around the ear. Well, sorry to bust your bubble but any ear muff will suffer a little bit if wearing shooting glasses with them. I use Radians Revelation Protective Shooting Glasses and they work extremely well with these L0F earmuffs, I just angle the ear pieces up 30 degrees so they are not resting on my ears... instead they are up on the side of my head and not interfering with the ear muffs. Perfect!Another added benefit of these ear muffs is that they will not interfere with the stock of your rifle when looking down the sights because of their low profile. Any other big ear muffs will interfere for sure.For their design and price, these Howard Leight ear muffs are excellent! Just know what you are buying so you don't expect the same performance of a larger, bulkier ear muff.

Decent but there are more better and cheap options
Alright, so I had this ear pro and it is really good in terms of comfort. You also get somewhat decent hearing protection when firing guns and it is is slim enough to allow you to mount your guns easily. The foam is recessed inside the ear pro for more room which is why you can wear it for long hours. The cons is that you can get a cheaper pair of walker ear protection muffs which is slimmer due to tapering downwards, has more substantially mlre foam than the howard leight LF2, and will reduce sound much more effectively. These are decent headphones in that if you double up, it will be more comfortable than walkers. However the walkers will be much more quiet.

Ear Protection
These were purchased to cut down the level of noise when I till my soil using a gas powered tiller. Once you get a solid fit you will be protected. They are also easy to clean with a micro fiber towel. I got the black and they look sleek and stylish. Lawn cutting season is coming and I plan on using them then as well. Other people buy them for firearm related activities so they are versatile for many people. Its a purchase that you will make once and will end up keeping for many years and using for various tasks. Can't go wrong with buying something like that. Photos if product after one use and wiped down.
