3M Reinforces Preparedness to Defend Combat Arms Earplug Litigation Docket

Read More

3M has a long history of partnering with the U.S. military. We are committed to making products that help protect our troops and support their missions. Unfortunately, this commitment is being misconstrued in the Combat Arms Earplugs Version 2 (CAEv2) litigation. We want you to have the facts. Read up on the latest updates.

What is the CAEv2 product

The CAEv2 product represents a significant innovation in hearing protection. It was the first earplug product to offer protection from loud sounds – like gunfire – while maintaining the ability to hear softer sounds – like speech – with limited interruption. The company worked in close coordination with the U.S. military on the CAEv2 product. In fact, its design reflected features requested and accepted by individuals acting on the military’s behalf. Learn more about the CAEv2 product.

Defending our record

3M has great respect for the brave men and women who protect us around the world, and their safety is our priority. Currently, the CAEv2 product is the subject of litigation and recent media reporting, and plaintiffs’ attorneys are attempting to tarnish our reputation. We are vigorously defending our record and demonstrating the CAEv2 product was effective and safe to use.

We are committed to using science and innovation to improve lives and solve the world’s biggest challenges, including those faced by the U.S. military. We are confident in our case and stand prepared to defend ourselves against plaintiffs’ allegations.
