Howard Leight by Honeywell 1010970 Thunder Series Noise Blocking Earmuffs with  Thunder T3, Headband Style and Dielectric
The Thunder Series offers top-of-the-line protection and all-day comfort. Its dielectric construction withstands use and abuse, while protecting employees in electrical environments. It features our patented Air Flow Control technology, providing optimal attenuation across all frequencies. Inside the snap-in AFC ear cushion, a series of holes allows the cushion to breathe more effectively and channels the air out of the base cushion, much like a car shock absorber. This controlled flow of air dampens low-frequency vibrations while maintaining excellent high frequency attenuation. Thunder's Quick-Click height adjustment remains fixed during wear, and snap-in ear cushions assist with easy maintenance. Available in three styles, Thunder offers a solution for most environments. The Headband styles (T1, T2, T3) provide a uniform headband pressure for all head sizes, providing better comfort for long-term wear. A non-deforming outer headband withstands rough treatment, while an inner ventilated headband on the T2 & T3 versions minimizes pressure on the head, and breathes easier in warm/humid climates. The Thunder Cap-Mounted styles (T1H, T2H, T3H) have earcups which snap in place during use and swing back when not in use. They also include SKU #13910039 Hard Hat Adapter for use with a wide range of hard hats AO Safety, Bullard, Jackson, MSA, North (Adapter 3718). And Thunder Folding style earmuffs (T1F) are designed for convenient and easy storage. A folding earmuff Belt Case is also available separately (1000251).
