Hand-built in Brooklyn, New York, where Grado has been family-run for six decades, these white headphones are a perfect example of the brand's meticulous approach to sound. The limited-edition headphones draw inspiration from the landmark Beatles album and are the first to have an all-white platter outer enclosure that utilizes an intricate curing process that optimizes the tonal quality. Grado also designed a new compact ventilation system that increases the mass of the maple wood and creates a fuller-bodied, deeper sound. And that sound is fully realized thanks to the drivers, which work in tandem with the maple housing to create warm harmonic tones, rich full-bodied vocals, excellent dynamics, and deep bass. The headphones are finished with a large white stitched leather headband with a 12-conductor cable feeding information to the drivers.
