Howard Leight Leightning L1 Slimline Passive Earmuffs 25 dB Gray

The Howard Leight Leightning L1 Slimline is a passive over-the-head earmuff designed to protect the ears from damaging noise levels. It uses Air Flow Control technology to regulate how sound reaches the ear, which the manufacturer says provides strong noise reduction in a slimmer profile than many competing designs.

The muff has a steel headband with soft foam padding, adjustable height, and snap-in ear cushions. It is rated at an NRR of 25 dB. This model uses the traditional over-the-head configuration; a behind-the-head version is offered separately as the L1N for use with hats or helmets.

The earmuff is gray and made primarily of foam. The product is not CE certified.
