Grado Labs is a Brooklyn based company that hand makes headphones and cartridges. Family run since 1953, Grado has seen three generations: Joseph, John, and Jonathan Grado.

As Ars Technica says, “…on a quiet street in south Brooklyn is a manufacturing operation that produces some of the most renowned headphones… it's just the Grados in their narrow townhouse making the little-known, well-loved line of headphones.”
