The 3M H540A-411 (Optime III) ear defender is engineered for extreme noise environments. It comes equipped with a double-casing acoustic system, a large internal cup volume, and wide, soft cushions, designed to reduce low- and high-frequency noise. The headband version is ideal for general industrial, construction and manufacturing settings where reliable hearing protection is critical.
The Optime III series from 3M is built to deliver dependable hearing protection in environments where noise levels exceed typical thresholds. The double-cup architecture improves attenuation at low frequencies, a common challenge in heavy-industry settings. Cushioned, spacious ear cups reduce pressure around the ears and enhance user comfort, helping maintain compliance during long shifts. Replaceable hygiene parts extend service life and reduce the total cost of ownership.

My student hates noise of any kind; So I bought this for him. He wears them all day and now his parents have decided to buy him a pair for the house. Definitely the best decision ever.
I bought this for my son for Monster Jam and he kept them the entire time. He's also autistic, so he likes to use them occasionally to block out loud noises.
