Abstract: A headset device comprising first and second headphones interconnected through a headband, wherein each of the first and second headphones comprises an earcup defining a unitary acoustic resonance chamber, a foraminous driver mount positioned offset from both a lateral axis and a longitudinal axis defined by the earcup, and a diaphragm retention ring extending from a surface of the foraminous driver mount. Each of the headphones further comprises a driver mounted within the driver mount and including a diaphragm, a foraminous unitary diaphragm support for maintaining the driver within the driver mount, an earcup cover attached to the earcup, and an earpad attached to the earcup.

Abstract: A soft, durable, nonwoven fabric formed of hydroentangled synthetic polymer fibers in sheet form. The polymer fiber is surface embossed on at least one major surface with a predetermined pattern to provide a fiber sheet having enhanced dimensional stability. The fiber sheet is surface napped to soften the surface and disturb and make indistinct the surface embossed pattern. The pattern may preferably be a twill pattern, and the napping process is preferably a wire-napping process. The fabric can be constructed into blankets and numerous apparel items.
