Launched over 60 years ago by Joseph Grado, the brand has remained in the family and in its current building — a former fruit store run by Joseph's father — for three generations. Today, they turn out around 60,000 phonograph cartridges (i.e. turntable needles) and 150,000 headphones by hand inside this modest 3-story workshop in Sunset Park, Brooklyn. The basement is reserved for the big gun machinery that produces the raw materials like the ear cup's plastic components. Here, an employee operates the automatic injection molding machine.
