The Walker Disrupter Ear Plugs are designed to protect your hearing by canceling dangerous-level noises, such as shots at the gun range or while target shooting. At the same time, the earbuds can be used to enhance desired environmental sounds or deliver superior audio originating from a cell phone, tablet, or other device through Bluetooth connectivity. This makes the Disrupter a completely comprehensive noise protection and a best-in-class sound enhancement solution for anyone with an active lifestyle — on the range, in the gym, or deep in the wilderness.
