An ergonomic headband with soft padding reduces the pressure on your head for superior comfort. Generous space inside the ear cups ensures breathability meanwhile soft imitation leather provides a tight sound-proof seal.
Adjustable headband and 360 rotatable ear cups with comfortable foam can be adjusted to fit most sizes from kids to adults (pull/push the earmuffs from the metal string to adjust the size).
Constructed by solid ABS shell and thickened noise-dampening foam.
Compact folding design for easy storage and convenient portability; the noise-canceling headphones fold up nicely to fit in a range bag, backpack or briefcase while taking up only a small space.
The stylish hearing protectors are ideal for shooting, hunting, sports events, studying, woodworking projects, and lawn care, extremely suitable for operating heavy machinery or landscaping business.

ANC Technology
The earmuffs have a noise cancellation circuit that can produce soundwaves that are the polar opposite of what the microphone takes up.
Active noise-canceling earmuffs will protect your ears and reduce stress in your life.
"Active Noise Cancellation" (ANC) is a method of shutting out ambient noise using a system of components housed in the ear cups.
Its microphones first receive the ambient noise. The sound wave data is then sent to a built-in chipset, which uses algorithms to create an opposing soundwave (180 degrees out of phase) that is played through the speakers.
