Cardas Ear Speakers EM5813 Model 1
Like New in Box. Never Demo’d Original box and Manual
Made from solid brass, polished, and then treated to a copperplate finish. The earpieces sport tiny rear-firing vents and feature very thick sidewalls, meaning they provide an unusually rigid and stable mounting platform for the drivers within. The drivers are 11.45mm dynamic units that feature extremely powerful neodymium magnets and diaphragms made of a distinctive, PEN (polyethylene napthalate) thin-film material.
