In the early 2000s, a company called Aearo Technologies developed what it deemed as combat-worthy earplugs—earplugs designed for members of the military, allowing them to hear verbal commands or enemy approach while shielding them from the ultra-high-decibel sounds of combat. Unfortunately for these veterans, Aearo’s design (later purchased and manufactured by household name 3M) was defective. Hundreds of thousands of veterans who used these defective earplugs later developed tinnitus or hearing loss.
If you or a loved one developed hearing problems after using 3M Combat Arms earplugs, you may be entitled to compensation for these injuries. Below, we answer some of the most common questions veterans have about the 3M Combat Arms earplugs lawsuit.

How Do I Qualify for a 3M Lawsuit?
To be eligible to sue 3M for your hearing loss or other hearing-related health issues, you’ll need to be able to prove three things:
- You served in a branch of the U.S. armed forces between 2003 and 2015;
- You were issued 3M Combat Arms earplugs during this time; and
- You suffered hearing loss or tinnitus after using the earplugs.
How Do I Claim 3M Earplug Lawsuit Benefits?
To take part in the 3M earplug lawsuit, it’s important to consult an experienced personal injury attorney. At The Ferraro Law Firm, we represent veterans and military members who have hearing damage from using 3M earplugs. The sooner you talk to an attorney, the more quickly your claim can be filed and proceed.
What is the Current Status of the 3M Earplug Lawsuit?
The first 3M earplug lawsuit was a qui tam whistleblower lawsuit that was filed in 2016. This lawsuit alleged that both Aearo and 3M knew about the defects in the Dual-Ended Combat Arms™ Earplugs, Version 2 (CAEv2), yet still allowed these earplugs to be distributed to soldiers fighting in Iraq and Afghanistan. This lawsuit alleged that the companies were required, but failed, to disclose this information about the defective product to the U.S. Defense Logistics Agency before executing a contract to provide these earplugs to the military.
Ultimately, 3M settled this whistleblower lawsuit for $9.1 million in punitive damages, payable to the Department of Justice. The whistleblower received just under $2 million of this judgment and the rest went to the U.S. Department of Justice, not the veterans who were injured by these earplugs. As a result, these veterans began to file lawsuits against 3M—currently more than 290,000 lawsuits and counting.
These lawsuits have been consolidated in multi-district litigation (MDL) and transferred to the federal district court in the Northern District of Florida, before Judge M. Casey Rodgers. They mark the largest mass-tort litigation in U.S. history.
How Do I Know if I Was Issued 3M Earplugs?
Because Aearo and 3M were the exclusive provider of dual-ended combat arms earplugs to the military for a 12-year period between 2003 and 2015, if you served during that time, it’s a safe bet you used these earplugs. Your military service or medical records will also have a record of the equipment distributed to you. Your attorney can investigate your claim and confirm that these were the earplugs you were issued.

To the general public searching for a competent aggressive law firm, I must recommend The Ferraro Law firm. After my first consultation with this firm, it was clear this was the right firm to handle my case.
I had tried a few others but was not impressed. In fact, the others made me feel like just a number. I’m a licensed general contractor with many years of experience. The main thing in my business success is, and has been, communication.
Ferraro Law has given me the very best communication I could ask for. As we all know, things don’t always happen overnight. This is where communication comes in.
My thanks to the Ferraro Law firm for transparency and diligent attention to all the details in my case.
I recommend them highly with a five star rating. 10 if I could.

I had a truly positive experience working with Ferraro Law Firm, especially Berta, who supported me every step of the way. From the beginning, she was kind, patient, and very clear in her communication. She set realistic expectations and checked in with me often, which made a big difference during a time that felt overwhelming in my personal life.
Receiving a settlement sounds like it should be simple, but it can actually be a lot to process. Berta made everything feel manageable. The process of signing documents and receiving my settlement was smooth and stress-free, and I always felt reassured that everything was being handled properly.
What stood out to me the most was how considerate and understanding she was of me as a person, not just a case. As a mother, that meant a lot. I truly felt supported throughout the entire experience.
I’m very grateful for the help I received and would absolutely recommend Ferraro Law Firm to anyone looking for professionalism, guidance, and genuine care during a legal process.
