3M Combat Earplugs Caused Hearing Injuries
In July of 2018, the United States Department of Justice announced that 3M had agreed to pay $9.1 million in order to resolve allegations that they knowingly sold the Dual-Ended Combat Arms™ Earplugs, Version 2 to the U.S. military without disclosing defects that hampered the effectiveness of the hearing protection device. The ear plugs were originally manufactured by Aearo Technologies, which was acquired by 3M in 2008.
