The GS1000x is the first full-bodied headphone to take advantage of the larger 50mm X Drivers. Specifically tuned to bring forth the warmth mahogany produces, this new speaker design features a more powerful magnetic circuit, a voice coil with decreased effective mass, and a reconfigured diaphragm. Reengineering these components for our 50mm drivers improve efficiency, reduces distortion, and preserves the harmonic integrity of your music.
