The OTTO NoizeBarrier TAC and the 3M Peltor ComTac V Hearing Defender are both top-notch pieces of communication and electronic hearing protection technology. It can be challenging to choose between these two headsets with their competing features like balance modes and physical durability. In this article, Mission Critical Communications Review will be comparing the two headsets’ design and technological features, and prices.

Read this article to make your final decision—OTTO or 3M Peltor.


When choosing what communications headset is also useful for protecting your hearing, design may not seem like a deciding factor. However, when choosing technology for critical communications, many of the decisions are based on the situation the technology will be used for. Design is a large part of situation-based communication technology.

From headbands to color, design is integral to choosing the right headset.


  • Easy to access volume controls on the left earcup
  • “Ultra-soft Comply” foam ear cushions
  • Ear Cushions are easy to snap off and replace quickly
  • Low-profile earcup
  • Compatible with major Hi-Cut helmet systems
  • Comes in black, flat dark earth, and olive drab green
The OTTO NoizeBarrier TAC

The OTTO NoizeBarrier is filled with design features that make it user-friendly and overall a convenient product. Because the ear cushions are easy to snap off and replace, this OTTO headset is a great addition to your tactical gear. Convenience and efficiency are key for any field situation.

A low-profile earcup that does not impede the user’s movement is pertinent for those who are intending to use this gear when using firearms that are propped on the shoulder. In addition to the low-profile earcups, OTTO ensured their headset is compatible with major Hi-Cut helmet systems. Their detailed design is perfect for any tactical situation.


  • Rubberized head band
  • Removable head band to convert to ARC adapters to use with a helmet
  • Easy to access battery compartment for quick battery replacement
  • Comes in coyote brown, O.D. green, and black

The original 3M Peltor ComTac hearing defender came with a leather headband; however, the ComTac V hearing defender now comes with a rubberized headband. The rubber material will be more durable than leather in outdoor situations that may include inclement weather or any kind of moisture. When investing in an expensive product like electronic hearing protection, you want to make sure what you are buying will last.

Moreover, a communications device needs to be versatile. The 3M Peltor ComTac V is able to convert to a headset that is compatible with most helmets from its easy-to-use ARC adapters. The Peltor Comtac V’s design is durable and efficient.


In addition to design, technology is a prominent part of the decision-making when choosing your communications headset. Both the OTTO headset and Peltor ComTac V have outstanding technology features; buyers like you just need to know what they are prioritizing. Electronic hearing protection and communications headsets are constantly improving. Let’s see what the OTTO NoizeBarrier and 3M Peltor ComTac V offer.


  • Dual Comm Speakers
  • 360 degree situational awareness microphones in each earcup
  • Selectable signal separation
  • 100 hours of battery life
  • Noise reduction rating (NRR) of 23 dB

The OTTO NoizeBarrier dual comm speaker changes loud or sharp sounds to a safe level. At the same time, the speakers are able to detect normal nearby conversation and radio communication. Normal conversation can be heard without any technical changes for the user.

Moreover, each ear cup also has 360-degree situational awareness technology; this allows the user to have the ability to locate sounds accurately as if they were not wearing a headset at all. This technology is key to knowing the direction of any potential threats or warnings.

The OTTO NoizeBarrier TAC is considered electronic hearing protection; it is also a communications headset that comes with a noise-canceling boom microphone that has built-in wind and noise reduction technology.

Not only is the OTTO headset protecting you from noise-induced hearing loss with an NRR of 23 dB, but it is also a great tool for clear and effective communication between you and your teammates.


  • Omni-directional microphones and high-fidelity speakers
  • Balance mode
  • Release time
  • 150 hours battery life
  • Can be changed to a full team communications headset
  • NRR 22 dB

With omnidirectional microphones and high-fidelity speakers, the 3M Peltor ComTac V Hearing Defender can pick up voice communications and warning sounds. The accurate sound replication has a natural sound with unmatched clarity even with an NRR of 22 dB.

The ComTac V audio also includes balance mode; this adjusts the environmental listening volume between the left and right ear cup speakers. Balance mode then allows the headset user to prioritize audio or adjust accordingly.

The 3M Peltor ComTac V is a flexible product that can be adjusted and altered to fit the user’s needs. For instance, the hearing defender is a great electronic hearing protection headset and with only a few additional pieces it can be transformed into a communications headset.
