Shooters and hunters, listen up! These Caldwell E-MAX Power Cords are way smarter than your basic foam earplugs. They're electronic earplugs that protect your hearing (with a solid 22 Noise Reduction Rating) but let you hear normal conversations and ambient sounds. The cool part? They have built-in Bluetooth! You can connect them to your phone and listen to music, podcasts, or take calls while you're at the range or in the stand. Then, when you fire a shot, they instantly block the loud blast. They're super comfortable with multiple silicone tip sizes to get a perfect seal in your ear, and they're connected by a cord so you won't lose one. They automatically shut off after 4 hours of no use to save battery. Perfect for when you need to stay aware of your surroundings but also want some entertainment or need to protect your ears from rifle and pistol fire. Comes with Caldwell's limited lifetime warranty for peace of mind.
