Available only at Hammacher Schlemmer, these are the headphones with circumaural earcups made entirely of African zebra wood. Both the natural high density of zebra wood and the elliptical interior of each earcup control standing waves and resonance that can muddy a signal, providing rich, full sound. The soft sheepskin earpads block outside sounds and provide comfort. A stainless steel band joins both earcups and a sheepskin headband provides a comfortable fit. Rated for 32 ohm impedance, the 50mm neodymium drivers provide a frequency response of 18Hz to 22KHz for robust bass, a balanced midrange, and crisp highs. Although they are rated for 50mW of power input, they can withstand 70mW of input power for up to one minute. They provide 112 db SPL/mV sensitivity. The headphones have a 10' cable that terminates in a gold-plated 3.5mm mini-plug and a gold-plated 1/4" screw-on adapter. Includes a silk-lined basswood veneer storage box (3 lbs.) Headphones (11 1/4 oz.)
