– Multi-position designs, available in headband, neckband, helmet-attachable and folding models.
– Stainless steel construction resists bending and warping.
– Earcup pivot points tilt for optimum comfort and efficiency.
– Ultra light with liquid/foam filled earmuff cushions.
– Color-coding for compliance sighting.
