Note: As of 2020, 3M Peltor has discontinued the Peltor Comtac III headset and replaced it with the 3M Comtac V with advanced features and an improved design. Learn more about the improvements made to the Comtac V compared to the Comtac VI.


Popular brands in hearing protection are the Peltor Comtac III headsets and the MSA Sordin Supreme Pro X headsets. Both the Peltor Comtac III and Sordin headsets were developed to correspond to international military specifications and are designed specifically to prevent hearing damage.

Both of these noise-canceling communication headsets are able to provide clear communication with ambient listening and feature instant impact noise protection. 

According to the U.S. Department of Veterans Affairs (VA), more than 2.7 million veterans currently receive disability benefits for hearing loss or tinnitus, a ringing in the ears.

The Department of Veterans Affairs reports the entitlements to reach in excess of $1.2 billion for compensation for the care of hearing loss and auditory system injuries in over 1.8 million Veterans in 2012 alone. The U.S. Military tries preventing hearing loss by providing warfighters with hearing protection.

When choosing between the MSA Sordin VS Peltor Comtac III, users will want to consider several factors. These factors include,

Noise Reduction Rating

Noise reduction rating is one of the most important features to consider when choosing hearing protection.

Peltor Comtac III offers NRR 20dB. 3M Peltor Comtac III headsets are tested at a 3M NVLAP accredited facility. The Sordin has only 18dB NRR in comparison.

With both headsets, loud volumes, that can potentially cause hearing loss, are suppressed, and low volume sounds are amplified providing seamless two-way communications.

With this amplification feature, the user can easily hear people talking around them at any volume level. When comparing the MSA Sordin vs Peltor III, both headsets have good hearing protection although the Peltor Comtac III has a higher overall NRR rating.

Comms Configurations

Both the Peltor Comtac III and the MSA Sordin Supreme Pro X are available in various models. Model features include either single comm or dual comm headsets. Single comm let's you connect the headset to one external device, like a two-way radio, while the dual comm lets you connect to two external devices.

The 3M Peltor Comtac III has a hearing defender configuration that does not allow connection to external devices so you would use the headset more for hearing protection. With this, the hearing defender headset doesn't allow for comms back and forth to your team.

Both noise protection communication headsets are available in various colors which include coyote brown, olive drab green, black, or foliage green.   

Below we have included a list of the features of each respective noise-canceling communication headset.

What Others Are Saying About the Comtac III

"Amazing and unparallel quality sound. You’re gonna hear like an Apex predator with this while getting protected."


"These are outstanding! I have always been apprehensive of the Peltor ComTacs, mostly due to price and the fact that they are primarily made to be used as com headsets. Well, while its true they were developed primarily as communication devices, they are outstanding ear protection as well! They are extremely comfortable and perform extremely well. Well worth the cost!"


"The volume controls are easy to use and responsive, and you've got the ability to adjust stereo balance and other finer controls to get things just the way you like. The Comtac 3 has the very best sound quality in any set of electronic hearing protection I've ever worn."


To prevent hearing loss both headsets provide exceptional hearing protection in high noise environments that require seamless two-way radio communications.
