US Patent 7853034 Ambient noise isolation audio headphones having a layered dampening structure

An audio headphone apparatus having ambient noise isolation properties for musicians and sound engineers which allows a user to substantially attenuate ambient noise levels and focus on the electronic audio presented to the headphones. The apparatus utilizes a unique layering of absorber materials with unique geometric shapes which in combination highly attenuate external ambient acoustic energy and control undesirable “boomy” bass response. The apparatus further utilizes a desiccant material within the ear cuff cover which helps to absorb perspiration or other moisture.
