3M Combat Arms Earplugs


Between 2003 and 2015, manufacturer and United States military supplier 3M supplied a version of the Combat Arms Earplugs (CAEv.2) as standard-issue hearing protection to service members in both Iraq and Afghanistan. Recently, the U.S. Department of Justice (DOJ) reported the company has paid over $9 million to settle a lawsuit over this defective product.

What Went Wrong?

Allegations now suggest 3M—and its predecessor, Aearo Technologies, Inc.—neglected to inform users how to properly apply or use the devices. Despite being aware of potential design defects, 3M continued to supply the product as standard-issue hearing protection to the armed forces—and service members suffered hearing loss or deteriorated hearing as a result.

The design of 3M Combat Arms Earplugs makes them difficult to insert properly and unlikely to seat correctly. Since the manufacturer did not disclose information on steps required to properly insert and correctly seat the product, users suffered an array of hearing problems. These included:

  • Newly Developed Hearing Loss
  • Worsening of Existing Hearing Loss
  • Tinnitus or Ringing in the Ears
