3M Earplugs

Thousands of veterans filed lawsuits against 3M, claiming that the company's Combat Arms Earplugs were defective and led to hearing loss and tinnitus. The lawsuits allege that 3M knew about the defects but failed to disclose them to the military or adequately warn users. These cases have been consolidated into an MDL, and significant jury verdicts have been awarded to plaintiffs. 3M has faced substantial financial liabilities and continues to contest the claims while negotiating settlements in some cases.
