The hexagon-shape enhanced structural design gives maximum strength against bending and physical damage. Designed for extensive use, the large speaker chambers cover most ear sizes comfortably. They're not only durable, they provide noise canceling for use in busy environments. Padded ear covers offer comfort in situations that require many hours of use. Built-in acoustic shock protection (ASP) provides a circuit-breaker-type protection against sudden loud noise from the speaker source.
