The Caldwell E-MAX Electronic Earmuffs deliver hearing protection that actually lets you stay connected at the range or in the field. Unlike passive muffs that muffle everything, these electronic earmuffs amplify quiet sounds—range commands, conversation, environmental cues—while instantly shutting down when noise hits dangerous levels. That means you get real-time situational awareness without sacrificing the hearing protection you need. With an NRR 25dB rating, they're built for shooters and hunters who refuse to choose between safety and function.

The E-MAX uses stereo microphones in each cup, so you can pinpoint sound direction naturally. Ambient noises below 85 decibels get amplified for clear communication; anything above that threshold triggers automatic shutdown to guard against impulse noise from gunfire. It's simple, effective technology that's been the standard in active hearing protection for years.

Powered by two AAA batteries (not included), the E-MAX is compact and field-ready. The ear cups measure 1.75 inches wide, sized to fit most shooters comfortably during extended range sessions or hunting days. Available in green to blend into your gear setup.

Frequently Asked Questions

Are Caldwell E-MAX earmuffs good for rifle shooting and indoor ranges?

Yes. The automatic shutoff above 85 decibels protects against impulse noise from gunfire, while the amplification of quieter sounds lets you hear range commands and other shooters. They work well in both indoor and outdoor shooting environments.

Do the electronic earmuffs come with batteries?

No. The E-MAX requires two AAA batteries, which are not included with the earmuffs.

Can I hear directional sound with the Caldwell E-MAX?

Yes. Each ear cup has its own stereo microphone, which allows you to localize sounds coming from different directions naturally.

How do the microphones work during loud shooting?

The microphones amplify sounds below 85 decibels for normal communication. Once noise exceeds 85 decibels—such as a gunshot—the microphones shut off automatically to protect your hearing.
