Thunder T1 Noise Blocking Headband Earmuffs - Dielectric. Thunder series earmuffs are designed with all-day comfort in mind. Thunder headband earmuffs feature a unique dual headband for better positioning and breathability and a non-deforming outer headband that minimizes pressure on the head. Plus, its dielectric construction withstands use and abuse, while protecting workers in electrical environments. The Thunder series features patented Air Flow Control technology for optimal attenuation across all frequencies and also snap-in ear cushions for easy maintenance. Howard Leight's patented Air Flow Control delivers optimal attenuation across all frequencies, without increasing ear cup size or weight. A patented base plate chamber and high-tech, non-woven layer, manage the flow of air inside the earmuff to control how sound reaches the ear. The result is better, more consistent, overall attenuation for virtually all industrial noise environments. Air Flow Control is a standard feature on all Thunder series earmuffs.

  • Dielectric construction suitable for all workplaces, especially electrical environments
  • Uniform headband pressure for all head sizes, providing better comfort for long-term wear
  • Non-deforming outer headband withstands rough treatment in the toughest workplaces
  • Quick-click height adjustment remains fixed during wear
  • Snap-in ear cushions make replacement quick and easy

Rated 5.0 out of 5.0 by BEST BUY I needed earmuffs for while, what I have been putting in my ears were small plugs that did not do the job like these earmuffs, they are great and I just love them, and they hang on my neck fine , whent I am not wearing them. I wish that I would have gotton them years ago. The color is great looking. THANKS! June 24, 2015
Rated 5.0 out of 5.0 by Very Useful Product for child My great grandson uses these headphones while we work in the yard with loud power equipment and flying in airplanes, seeing as we travel. These headphones block noise so that they do not damage his hearing. My grandson wears these while he rides his John Deere mock lawn mower. September 13, 2013

Rated 4.0 out of 5.0 by Protect what you hear! Protecting hearing is important, so when I am on the riding mower, using a vacuum or going to a race track - these come in handy! I bought an extra pair for my 7 yr old (they adjust well for young and adult). May 1, 2012

Rated 4.0 out of 5.0 by Good Noise Blockers I used this pair of earmuffs for weedwacking. They work well, I didn't lose my hearing so that's a plus. They look well built and I hope they will last for years. May 21, 2013
Rated 3.0 out of 5.0 by Ears ring pretty loudly. Blocks out most all sound. They feel like they have an airtight fit. They made my ears rings pretty loudly while using them and after using them for quite a while. July 10, 2013
