About the GS1000x
The Grado GS1000x is part of Grado's Statement Series, representing their fourth-generation 'x' series headphones. Hand-assembled in Brooklyn, these headphones feature a hybrid wood housing combining mahogany and ipê, which enhances the signature warm and rich tonal characteristics. The GS1000x utilizes large 50mm X Series dynamic drivers with a more powerful magnetic circuit, a voice coil with decreased effective mass, and a reconfigured diaphragm to improve efficiency, reduce distortion, and preserve harmonic integrity. The open-air design delivers an expansive soundstage with exceptional clarity and detail. The headphones include a durable 12-conductor super-annealed copper cable and a black leather headband with white stitching for comfort and durability. They are designed for audiophiles seeking immersive, natural, and musical listening experiences.
