Read this article to determine which headset is right for you and your industry.

Design Features

Sensear SM1R

  • Weighs only 14.01 oz.
  • Available in headband, behind the neck, and helmet style
  • Comes in black

The Sensear SM1R weighs only 14.01 ounces from its lack of battery. The lighter weight makes it comfortable to wear during long hours. Although it only comes in one color, it can be worn three different ways. The headband is the most typical; however, in some industries a helmet might be necessary. In these situations, the Sensear can be modified to a helmet style.

The SM1R is a great communications headset that can be beneficial in many areas of work.

3M Peltor Litecom PRO III

  • Padded headband
  • Weighs 17.3 oz.
  • Comes in bright yellow, navy blue, and royal blue

With a padded headband, 3M Peltor made sure the Litecom PRO III is comfortable and durable. Unfortunately, this headset does weigh a bit more due to the battery pack compared to the Senesar SM1R that does not have a battery pack. Later in this article, we'll explain why it is beneficial for your headset to have its own battery.

3M Peltor Litecom Pro III Headset

The Litecom PRO III also comes in three colors, offering variety for different workplaces. The bright yellow is great for construction like roadwork where high visibility is a must.

3M Peltor specifically designed the Litecom PRO III for comfort and versatility.

Technology Features

Sensear SM1R

  • No battery in the headset, it is powered through the radio it is connected to
  • NRR of 19-27 dB
  • Noise-canceling boom microphone
  • VOX capable
  • In-ear noise exposure limited to 82 dB
  • Intrinsically safe

The Sensear SM1R communications headset has a variety of technology features. Because the Sensear headset is powered through the radio its connected to, you never have to worry about having your headset charged. One less tool to charge for your workday is one less thing on your long to do list.

Another convenient technology feature for the Sensear headset is it is intrinsically safe. This designation means the headset is verified to be a safe piece of technology to use even in hazardous situations.

In hazardous work environments, there tend to be loud noises from large machinery and other hazards. The Sensear SM1R headset has an NRR of 19-27 decibels. The NRR varies by how the headset is worn. It is most effective when worn with the headband on the top of the head.

Lastly, the Sensear headset is a great option to keep communication flowing while on the job. With a noise-canceling boom microphone, you can ensure your speech will transmit clearly even in loud environments.

Overall, the Sensear SM1R has a multitude of technology features. It is great to reduce noise exposure and use as a communications headset.


3M Peltor Litecom PRO III

  • 11 hours of battery time
  • NRR of 28 dB
  • Environmental microphones
  • Noise canceling waterproof microphone
  • VOX capable
  • Bluetooth
  • Built in two-way radio

The 3M Peltor Litecom PRO III is a sturdy communications headset with many great technology features.

The 3M Peltor headset does have a battery, a Li-ion pack, that is rechargeable and can last 11 hours. The battery does make this headset a bit heavier and the user has to make sure it is charged every 11 hours; however, when a headset has its own battery, it can function without a radio attached.

In some cases, you may not need to always use your headset for communications purposes, but you still want to protect your hearing; because the 3M Peltor Litecom PRO III is powered by battery, all microphones and technology used to provide the NRR of 28 dB will still work without a radio connection.

In the event you are using your 3M Peltor for communications purposes, the noise-canceling and waterproof microphone that comes with the Litecom helps create clear transmission even in loud environments like construction sites.

Moreover, the Litecom is VOX capable. “VOX” stands for voice operated exchange. This technology feature can be useful in work environments where time is of the essence or when machinery requires both hands.

The 3M Peltor Litecom PRO III is an outstanding communications headset that is flexible for a variety of environments.
