Grado Headphones
RS1x
Tri-wood reference.
The RS1x is the flagship of Grado's Reference series — the first headphone to combine three different wood species in a single housing. A maple sleeve handles most of the acoustic work, a hemp core smooths out the top and low ends, and a cocobolo outer ring adds punch and vibrancy. The 50mm X Driver is specifically tuned for this tri-wood combination, with a more powerful magnetic circuit, lighter voice coil, and reconfigured diaphragm delivering a rich, detailed sound that rewards deep listening. An 8-conductor super-annealed copper cable and black leather headband with white stitching complete a headphone of extraordinary craft.

Technologies Inside
4th-Generation X Drivers
More power. Less mass. More music.
Grado's 4th-generation X Drivers feature a more powerful magnetic circuit using rare-earth alloys, a voice coil with decreased effective mass using copper-plated aluminium, and a reconfigured 'de-stressed' diaphragm. Available in 44 mm (Prestige/Reference) and 50/52 mm (Statement/Signature) sizes, each driver is tuned for its specific housing material and matched to 0.05 dB per pair — improving efficiency, reducing distortion, and preserving the harmonic integrity of your music at every volume level.
Tonewood & Metal Housings
Every material has a voice.
Grado selects each housing material for its unique acoustic signature: cocobolo for vivid punch, Brazilian walnut for relaxed warmth, mahogany for tonal richness, maple for balanced clarity, hemp for smooth extension, and machined aluminium for surgical precision. Many models combine multiple woods — the RS1x uses maple, hemp, and cocobolo together — to create complex, layered acoustic characters that synthetic housings cannot replicate. Every housing is hand-shaped at the Brooklyn workshop.
