About the Case
From 1999 to 2015, 3M knowingly marketed, manufactured and sold dangerously defective earplugs, specifically the Dual-Ended Combat Arms Earplug, Version 2 (or CAEv2), to consumers and the United States Military. The earplugs were marketed as dual-purpose - wearing them one way would allow sounds such as speech to be heard while also blocking loud impulse sounds like battlefield explosions, and the opposite end was designed to block as much sound as possible. Neither side worked as represented to the soldier, thus providing far less protection than was needed for our service members.
However, based on the company’s own testing, the CAEv2 were dangerously defective. The earplug could loosen, allowing noise to pass through and subsequently cause serious hearing damage. The lawsuit alleges that 3M was aware of this defect and manipulated its testing by changing the standard fitting procedures to achieve favorable results.
At no time did 3M warn the military, servicemembers or the public that its product was faulty - leaving servicemembers unknowingly exposed to dangerous levels of hazardous noise. In 2015, 3M discontinued the CAEv2, and in 2018, reached a $9.1 million settlement with the federal government to resolve a whistleblower complaint regarding the sale of these earplugs to the Department of Defense.
Today, thousands of civilians and military personnel suffer from hearing loss, tinnitus, and/or additional hearing-related injuries, which have been shown to lead to higher risks of insomnia, social isolation, depression, anxiety, Post Traumatic Stress Disorder (PTSD), and suicide.
The Bottom Line: 3M rigged its tests, concealed known defects, and created misleading marketing materials to capture lucrative military contracts, and knowingly jeopardized the health and safety of the men and women who fight for our country in the process. When our servicemembers put their lives on the line or train here at home, they should not have to worry about the adequacy of their equipment. Accordingly, we plan to hold 3M accountable and ensure servicemembers and others injured by these earplugs receive the care and support they deserve.


Timeline
