The Howard Leight R01524 Leightning L1 delivers professional-grade hearing protection with 25 dB Noise Reduction Rating for shooters who demand reliable performance. This over-the-head passive design eliminates the battery dependence and electronic complexity that can fail when protection matters most.

What Makes This Different

The Leightning L1 features dual-wall foam ear cushions that create superior acoustic sealing compared to standard single-layer designs. The patented Air Flow Control technology manages internal air pressure to prevent the muffled sensation common with cheaper alternatives. Steel wire headband construction maintains consistent clamping force through thousands of uses, while the low-profile cup design allows proper rifle stock positioning.
