About the RS1x
The Grado Labs RS1x is a redesigned reference-series headphone hand-built in Brooklyn, NY, introducing fourth-generation 50mm X drivers tuned for tri-wood enclosures combining maple, hemp, and cocobolo. These open-air, dynamic transducers feature de-stressed diaphragms, powerful magnetic circuits, reduced voice coil mass, and matched pairs within 0.05 dB for superior efficiency, low distortion, and preserved harmonic integrity. Equipped with an 8-conductor cable, white-stitched leather headband, and replaceable L-cushions (G-cushions optional for comfort), the RS1x delivers Grado's signature open, detailed, agile sound with improved clarity, soundstage, and refinement over predecessors. Easy to drive, they excel in transparency, imaging, and musicality across genres.
