Started by his uncle, John Grado now runs the family business that manufactures some of the industry’s highest performing headphones, ear buds, and phonograph cartridges. They’ve never advertised, relying only on word of mouth and professional reviews to tell their story. Each item is hand made in the same Brooklyn facility where the company originated. Wood as a component of headphones? Yep. All stringed instrument’s sounds are enhanced by the wood they’re made from. Why not headphones? Brilliant idea. Brilliant sound.
