Wide cushioned headband earpads
Attention to details was made when designing the headband and earpads. With the design of a wide headband, the weight gets distributed to a larger area by dispersing weight evenly. The earpads are designed to fit a variety of head shapes along with the design of the curve behind the ear to be ergonomic so it creates an even seal all around the ear for a good fit.
Seems like a good deal, anybody here have them?
