Aearo Technologies, which is now owned by 3M Company, in the year 2000 manufactured the Combat Arms Earplugs ™ (CAEv2) for military use. During the manufacturing process, the company identified a defect in the design, which made the earplugs inapt to fit appropriately in the ear canal of the user and sealing it, thus failing to do what its designed for i.e. protecting the ear canal from damaging noise. When 3M entered into an agreement with the U.S. military to supply these earplugs, thousands of military service members were given these faulty earplugs along with a false sense of protection from high-level deafening & damaging noise.

It is alleged that 3M knowingly sold these defected earplugs to the US government, as it was difficult to identify the fault and not even experienced audiologist could tell if they were faulty or not. From the period of 2003 to 2015, these defected 3M earplugs were issued to the military personnel to be used during various missions. The purpose of these 3M Combat Arms Earplugs ™ (CAEv2) were to enable military personnel to stay in touch with the command center while blocking the external noise.

Those who have used these 3M earplugs reported hearing loss and tinnitus and according to the U.S. Department of Veteran Affairs it became the major causes of service-related disability among military personnel. If you have been into service during the said period and have suffered from any of hearing-related problems, then now is the time for you to come forward. Hundreds of military personnel are already filing lawsuit against 3M and Aearo after sustaining damage and we believe that if you have been affected then you should seek compensation by filing a lawsuit against 3M or joining the 3M earplugs lawsuit and not suffer in silence.


A lawsuit verdict in July 2018 also referred to as 3M earplugs lawsuit declared 3M Company guilty for selling flawed combat arms earplugs despite having knowledge about the damage it could cause. Due to the lawsuit, 3M paid $9.1 million as settlement, but the amount went directly to the U.S. military as the case was filed under the False Claims Act.

Veterans of the U.S. military who have used the CAEv2 made by 3M Company reported several problems mainly partial or complete hearing loss and tinnitus. The hearing problem has impaired the ability of those who have served in the military to live as they could have and cost them numerous opportunities to advance their careers. The 3M Combat Arms Earplugs ™ (CAEv2) had a design defect which would let the damaging/deafening sound pass through the earplugs, causing damage to the ear canals.

If you have served in the U.S. military from 2003 to 2015 and have developed hearing related problems after using 3M Combat Arms Earplugs ™ then you can file a lawsuit against 3M seeking compensation for:

  • Past and future medical expenses
  • Emotional distress caused
  • Losing your source of income
  • Reducing your capacity to earn
  • Pain & suffering you have experienced


Now is your time to come forward and seek compensation for the damages sustained that could’ve been avoided, had 3M Company acted ethically and informed the concerned authorities about the disadvantages of using their Combat Arms Earplugs ™.
