If you served in the military and now deal with constant ringing in your ears or noticeable hearing loss, you may have heard about the lawsuit against 3M over its Combat Arms earplugs. It’s one of the largest product liability cases in U.S. history, and if you’re only now connecting your hearing problems to your service, you’re probably wondering whether you still have a way to seek compensation.
This article walks through what the 3M Earplug Lawsuit is, who was eligible, and what steps make sense if you believe you were affected but never pursued a claim.
What Was the 3M Combat Arms Earplug Lawsuit About?
At Stewart & Stewart Attorneys, we’re often asked by veterans whether they still have options after hearing about the 3M earplug settlement for the first time, sometimes years after their service ended. To understand where you stand, it helps to start with what this case actually involved.
The lawsuit centered on Combat Arms Earplugs, Version 2 (CAEv2), a dual-ended earplug issued to U.S. military service members from 2003 to 2015. Veterans alleged the earplugs had a design flaw that caused them to loosen without the wearer noticing, reducing the protection they were supposed to provide against loud, damaging noise, such as gunfire and heavy equipment.
Hundreds of thousands of veterans came forward reporting tinnitus (persistent ringing or buzzing in the ears) and noise-induced hearing loss that they connected to using these earplugs during service. The claims were consolidated into a multidistrict litigation in federal court in Florida, and in 2023, 3M agreed to resolve the litigation for a settlement in the billions of dollars, to be distributed to eligible claimants over several years.
Who Was Eligible to File a Claim for the 3M Earplug Lawsuit?
Generally, eligibility for the settlement program applied to people who:
- Served in the U.S. military between 2003 and 2015
- Were issued and used Combat Arms Earplugs, Version 2
- Developed tinnitus, hearing loss, or related hearing damage they believe is connected to using these earplugs during that service
Many veterans didn’t realize they qualified until years after their service ended, since hearing damage from earplug failure often develops gradually and isn’t always immediately obvious. Others experienced symptoms but didn’t connect them to the earplugs specifically until seeing news coverage of the litigation.
If you’re unsure whether your situation fits this window, speaking with product liability lawyers in Indiana who understand how these mass claims were structured can help clarify where you stand.
How Does Indiana Law Factor Into This?
Because the 3M earplug litigation was resolved largely through a federal court process rather than an individual lawsuit filed in Indiana state court, the timeline and rules governing claims came from the settlement agreement itself, not from Indiana’s standard personal injury statute of limitations.
That said, it’s worth understanding Indiana’s general rules in case you’re evaluating a related injury claim outside the settlement program. Under Indiana Code § 34-11-2-4, most personal injury claims in Indiana must be filed within two years of the date of injury. For product liability claims specifically, Indiana Code § 34-20-3-1 generally requires a claim to be filed within two years of when the injury was discovered or reasonably should have been discovered.
If your hearing loss is connected to something other than the CAEv2 earplugs covered by the settlement, for example, a different piece of defective equipment or gear, this is exactly the kind of situation where Indiana personal injury lawyers can help you understand whether the state’s product liability rules might apply to your case.
What Should I Do If I Think I Was Affected?
If you served during the relevant time period and are dealing with hearing loss or tinnitus, here’s a practical way to start figuring out where you stand:
- Pull your military service records. You’ll want documentation showing your dates of service between 2003 and 2015, and ideally, records showing you were issued earplugs.
- Get a hearing evaluation. A formal diagnosis from an audiologist or physician documenting tinnitus or hearing loss creates an important medical record connecting your condition to a specific cause.
- Talk to an attorney about your specific timeline. Whether you never filed a claim, aren’t sure if you were included, or have questions about what happened with a previous claim, a knowledgeable attorney can review your situation and explain your realistic options.

Frequently Asked Questions
Who was eligible for the 3M Combat Arms earplug settlement?
Generally, U.S. service members who used CAEv2 earplugs between 2003 and 2015 and later developed tinnitus or hearing loss connected to that use were eligible to pursue a claim through the federal litigation settlement process.
What is tinnitus, and how is it connected to this lawsuit?
Tinnitus is a condition involving persistent ringing, buzzing, or humming in the ears without an external sound source. Many veterans in this litigation reported developing tinnitus after using earplugs that allegedly failed to provide adequate hearing protection during service.
Do I need proof I used the earplugs to have a claim reviewed?
Documentation such as military service records, unit assignment history, and medical records showing a hearing loss or tinnitus diagnosis can meaningfully strengthen a claim. An attorney can help you identify what records are available and how to obtain them.
Is Indiana’s two-year statute of limitations relevant to this case?
Indiana’s two-year statute of limitations generally applies to personal injury and product liability claims filed in Indiana state court. Because the 3M earplug litigation was resolved through a federal settlement process, different timelines established by that settlement agreement typically governed those claims instead.
What should I do if I’m not sure whether I ever filed a claim?
Speak with an attorney who can help you look into your history and explain what, if anything, can still be done. Bringing whatever service and medical records you have to that conversation will help make the review as accurate as possible.
