3M Dual-Ended Combat Arms Earplugs

Lawsuit Campaigns for Attorneys

3M Company, a well-known Minnesota-based manufacturer, recently settled with the U.S. military over claims that 3M sold the government specially designed combat earplugs for troops on the front lines that were known to be faulty. 3M created two versions of these earplugs, the single-ended version, and the dual-ended version, and allegedly sold the dual-ended version to the government without disclosing any of the product’s defects. These defective earplugs were called the Dual-Ended Combat Arms Earplugs, part of the company’s Military Combat Safety Gear line, and until they were discontinued, they were standard issue equipment materials for several branches of the armed services.

What Are Dual-Ended Combat Arms Earplugs?

The 3M Dual-Ended Combat Arms Earplugs were designed to protect the hearing of the wearer using two primary functions; when inserted one way the wearer would be able to hear sounds at reasonable volumes, such as speech, and when inserted in the opposite direction the wearer would get better noise protection from sounds such as gunfire or explosions. While this design seemed promising, it was found that the earplugs did not reach deep enough into the ear due to the stem being too short. The flaw causes the earplugs to come loose and allow destructive sounds such as gunfire, explosions, and machinery to enter the ear canal, potentially damaging the wearer’s hearing. Claims of hearing damage and tinnitus have increased significantly due to this design defect.

3M Earplugs Lawsuit

On July 26, 2018, the Department of Justice announced that the 3M company would pay $9.1 million due to allegations of selling defective military earplugs to the U.S. Military. The 3M military earplugs lawsuit accuses the company of selling defective earplugs and failing to warn the military of the potential design defects that could lead to tinnitus and hearing loss.

The allegations connected to the settlement also include Aearo Technologies Inc, who was acquired by 3M in 2008. Both 3M and Aero Technologies were accused of knowing that the 3M earplugs were too short to be fully inserted into the ear and provide insufficient protection for users. Although 3M agreed to pay $9.1 million to the US Government to resolve these matters, the company has admitted no wrongdoing and accepted no liability.

Many pending defective 3M earplug lawsuits filed by U.S. Military veterans have been moved to a multi-district litigation (MDL) in the United States District Court for the Northern District of Florida, despite some cases originally requesting to be moved to the U.S. District Court for the District of Minnesota, the home state of 3M Company’s headquarters. The transferred lawsuits involve 3M’s Dual-Ended Combat Arms Earplugs that were used by U.S. troops from 2003-2015. These qualified cases will be seen by the Honorable Federal Judge Casey Rodgers, who is a U.S. veteran and well qualified to preside over a large products liability multi-district litigation. On July 27, 2020, Judge Rodgers denied 3M’s claim for using government contractors’ defense, in which protects companies from liability for defective products designed and produced for the federal government.
