3M Military Earplug Lawsuits

3M's Combat Arms earplugs have been linked to thousands of instances of hearing loss, tinnitus, and related problems experienced by servicemembers.

Military servicemembers require hearing protection in all variety of situations, from training to combat. For more than a decade, one of the most popular hearing protection products was 3M's Dual Ended Combat Arms earplugs. Then came allegations that the devices were defective, and that the company knew about the problems but failed to disclose safety risks to the military. 3M now finds itself facing hundreds of thousands of claims by active and veteran servicemembers, linking the faulty Combat Arms earplugs to hearing loss, tinnitus, and related health problems.

In this article, we'll look at the landscape surrounding litigation over 3M combat earplugs, and key considerations if you're thinking about bringing your own claim.

What Went Wrong With 3M Combat Earplugs?

Military servicemembers often receive earplugs or other hearing-loss prevention equipment—for use during combat, while serving in a potentially-hostile location, and during training exercises. From around 2003 to 2015, one of the most common standard issue hearing-loss prevention options was 3M's Dual-Ended Combat Arms earplugs. This product was fairly unique among earplugs in that it was two-sided: one side was meant to block/reduce sounds of any kind, but turn the device over, insert the other side, and high-decibel sounds like explosions were meant to be blocked, while low-decibel sounds like talking could still be heard. That was the idea anyway, but the devices had a tendency to sit at too shallow a point in the ear, and would often come loose, so that their ability to protect servicemembers' hearing was, at best, inconsistent.

A whistleblower's allegations of 3M's wrongdoing in connection with the popular earplugs led to a July 2018 False Claims Act lawsuit settlement, in which 3M agreed to pay $9.1M to the U.S. Department of Justice. The whistleblower's claims were serious: 3M was alleged to have known that its Combat Arms earplugs didn't work the way they were supposed to, but rather than address a clear safety defect, the company was said to have manipulated product testing to come away with the results it wanted, while withholding knowledge of the defect from the Defense Department. 3M acknowledged no wrongdoing, but in announcing the settlement, DOJ made clear that its allegations against the company largely echoed the whistleblower's claims.

Not surprisingly, 3M soon found itself staring at a wave of lawsuits by active and veteran servicemembers, alleging that their use of the apparently-defective Combat Arms earplugs caused a variety of health problems, including:

  • hearing loss
  • tinnitus
  • balance problems, and
  • anxiety, depression, and other psychological effects (military veterans' hearing problems, especially the ringing in the ears that often accompanies conditions like tinnitus, can contribute to post-traumatic stress disorder and other negative responses associated with traumatic events that occurred during service).

Were 3M Dual-Ended Combat Earplugs Recalled?

No, neither 3M/Aearo itself nor any product safety agency issued a recall of Dual-Ended Combat Arms earplugs. As mentioned above, in 2015 the company simply stopped making the product, and the military stopped contracting for any new orders of the earplugs. This absence of any formal announcement of potential safety-related problems with the earplugs (and lack of any concomitant warning of hearing-related risks posed by their use) probably didn't do servicemembers any favors. Had a safety recall been issued, it's likely that there would have been a more rigorous push to remove the earplugs as standard issue equipment, and a high-profile campaign advising servicemembers to stop using them.

Can I File a Lawsuit Over 3M Earplugs?

The number of servicemembers who have filed a lawsuit over hearing problems linked to 3M Combat Arms earplugs is well into six figures. If you're thinking about filing your own claim, there are a few crucial issues to consider.

First, have you actually suffered harm as a result of your use of 3M's product? Even if your military service included extensive use of 3M Dual-Ended Combat Arms earplugs, you can't file a successful lawsuit against 3M/Aearo (or anyone else) if you haven't suffered hearing problems or some other measurable harm that can be attributed to this issued equipment—even if it's clear that the earplugs didn't always work the way they were supposed to.

Cases like these require measurable harm, and that usually means diagnosis of hearing loss, tinnitus, or some other health problem that can be traced back to your use of 3M's earplugs during military service. Diagnosis is the first step in understanding (and proving) the nature and extent of your losses ("damages" in legalese), including medical bills, impact on your ability to earn a living, and more subjective effects like "pain and suffering."

Most lawsuits over the safety of 3M Combat Arms Earplugs are largely based on a legal fault theory known as "product liability," through which manufacturers can be held responsible for injuries and health problems caused by that product. Product liability can also hold manufacturers responsible for their failure to warn others in the supply chain of risks associated with the product's use—as 3M is alleged to have done by withholding information related to known safety concerns related to its combat earplugs. (Learn more about proving a product liability case.)

Besides diagnosis of a hearing problem or other health issue, if you're considering a lawsuit against 3M/Aearo, another initial point to consider is the statute of limitations. This is a law that sets a time limit on your right to file a lawsuit and get compensation for your losses. In many states, the statute-of-limitations deadline that will apply to a 3M Combat Arms earplugs lawsuit is the same as the one that applies to most personal injury lawsuits. But some states have a separate statute of limitations that applies to lawsuits over defective or unsafe products. In any event, you'll usually have two to three years to get your lawsuit filed (the time limit is longer in some states, shorter in a few), but it can be a challenge to figure out when the "clock" starts ticking in these kinds of cases.

Hearing problems don't always show up right away, even when their cause can be traced to use of a product or some other specific source. (In contrast, when you're hurt in a car accident, your injuries typically make themselves known immediately.) And when products like earplugs don't work the way they're supposed to, there's often a lapse of time between use of the product and the onset of health problems (that's especially so when use takes place over a number of years).

In the context of 3M earplug lawsuits, this potential lapse of time before the development of hearing loss and other symptoms is a big reason why the statute of limitations "clock" might not necessarily start running on the date of the servicemember's last use of the earplugs. Under what's often termed a "discovery rule," the clock might start only when the servicemember discovers (or should reasonably have discovered) that they were harmed by their use of 3M earplugs. That date might coincide with a diagnosis of a hearing problem, or the servicemember's first symptoms of a hearing problem. But keep in mind that if a significant number of years have passed between your last use of 3M earplugs (or since your discharge from the military) and the onset of your hearing problems, another time limit called the "statute of repose" might prevent you from bringing a case against 3M/Aearo. Your best first step is to talk to an attorney for details on lawsuit-filing deadlines and how they might apply to your specific situation.

Is There a Class Action for 3M Earplug Injuries?

It's not a class action, but the largest single consolidation of 3M earplug injury claims is in federal "multidistrict litigation" (MDL). By February 2021 the MDL —officially titled 3M Products Liability Litigation, MDL No. 2885, and being handled by Judge M. Casey Rogers of the United States District Court for the Northern District of Florida—included more than 200,000 individual claims, making it the largest MDL ever, according to Bloomberg Law.

(Note; there's typically too much disparity among individual cases in terms of variables like severity of plaintiffs' harm to make an injury-related class action appropriate for 3M earplug claims.)

A key decision in the MDL came in July 2020, when Judge Rogers turned back 3M's attempt to use the "government contractor" defense, which might have shielded the company from liability if it could be shown that the Combat Arms earplugs were designed and manufactured for the federal government. In his ruling, Judge Rogers stressed the fact that the earplugs were designed before any contract with the federal government, and without any input from the military.

In an MDL, one or a few cases are chosen to serve as "bellwethers" that might give all parties an indication of what to expect, setting the stage for a global settlement of some kind.

The first "bellwether" trial in the combat earplugs MDL, concluded in April 2021, brought bad news to 3M when the jury awarded $2.1 million in punitive damages to each of three veterans who claimed that their issued 3M earplugs failed to work properly. A punitive damages award like this—which the Florida jury ordered on top of a compensatory damages award covering the plaintiffs' medical bills, pain and suffering, and other harm—is meant to punish particularly egregious or outrageous conduct on the part of the defendant.

3M got a bit of good news in the second bellwether trial in June 2021, with a jury deciding that the company was not responsible for the plaintiff military veteran's hearing problems. This marked the first time 3M came away from a combat earplugs safety trial with a verdict in its favor.

Any relief on the company's part was likely short-lived, since just a few weeks later the jury in the third bellwether trial found in favor of a veteran who claimed his tinnitus was caused by 3M's earplugs. The company's liability wasn't deemed absolute, however. According to the jury, 3M's share of fault for the veteran's hearing issues was 68%, while the veteran was 32% to blame for his own "damages," which amounted to $1.7 million. So, under Florida's comparative negligence rule, the veteran is set to receive 68% of the $1.7 total damages, or a little less than $1.2 million.

It remains to be seen whether any kind of global settlement is in the cards for the MDL.

How Much Is a Typical 3M Earplug Lawsuit Payout?

Putting a dollar value on any kind of injury case is difficult, and lawsuits over 3M combat earplugs are no exception. A particular servicemember's damages—and therefore the amount of compensation they're likely to receive—depends on their very specific circumstances, including:

  • the details of the sevicemember's hearing problems and the related impacts of those issues, including prognosis for a full recovery, the need for future care, and the nature and extent of any potential psychological effects generated by the servicemember's hearing problems (ringing in the ears triggering PTSD and other trauma-related responses, for example).
  • effects on the servicemember's ability to earn a living, now and in the future
  • impact on the plaintiff's life, including ability to care for loved ones, perform necessary work around the house, enjoy hobbies and other activities, etc., and
  • any other negative effects of the servicemember's hearing problems and related issues.

Finding a Lawyer for a 3M Earplug Lawsuit

If you're an active or veteran servicemember who's thinking about filing a lawsuit over hearing loss or related issues that could be linked to your use of 3M combat earplugs, going up against 3M/Aearo (and potentially navigating the procedural landscape of the MDL) isn't the kind of thing you want to do on your own. Having the right attorney is a practical necessity, and can make a big difference in the outcome of your case.

Online resources like Nolo can help you connect with lawyers (via information submission features and chat). And asking for a lawyer referral from someone you know and trust can be a good start. Even if that lawyer doesn't handle product liability cases, they may be able to refer you to a qualified lawyer in their network. Get more tips on finding the right injury lawyer.

Questions to Ask a Potential 3M Earplug Lawsuit Lawyer

It's important to make sure you're prepared for your first meeting with a candidate attorney (even if it's virtual). Consider touching on the following topics:

  • How many years has the lawyer been practicing? What percentage of that time has been spent handling personal injury cases?
  • Does the lawyer's experience include product liability cases in general, or claims over the safety of 3M earplugs in particular? Experience with product liability cases often means the lawyer won't flinch when going up against large corporations like 3M/Aearo (and their rosters of lawyers).
  • Would the lawyer handle your case personally? It's normal for other members of a firm to work on a client's case, but it helps to know whom you'll be dealing with directly. (Learn about working with a lawyer on an injury-related case.)
  • Will the lawyer work under a contingency fee agreement? (That means if your case settles, or a trial ends in a verdict in your favor, the lawyer receives an agreed-upon share of your compensation). What's the lawyer's share? Does the share increase as the case progresses (this is known as a "sliding scale")? Who is on the hook for case expenses or "costs", and will any deduction of costs come before or after the attorney takes his or her share of your compensation?
