Introducing the Axil XCOR Pro II Electronic Ear Plugs. The Hear Control on the XCOR allows you to hear what's happening around you while protecting your hearing! The Digital Hearing Protection on the XCOR compresses loud noises rather than shuts them out/off. This allows you to hear all sounds around you, while the automatic compression protects against loud gunfire or other damaging noises over 85dB. Bluetooth Audio allows you to connect to your devices so you can enjoy your music, never miss a call or a text, and shows wherever you go to make this your go-to set of earbuds. These can even be paired with some Bluetooth-capable radios for 2-way communication.
