Grado RS1 Open-Air Headphones

50 mm X2 drivers, tri-wood cocobolo, hemp, and maple housings, a Signature Gold headband assembly, and L cushions

The Grado RS1 combines the companys 50 mm X2 dynamic driver with distinctive tri-wood housings made from cocobolo, hemp, and maple. Its tuning emphasizes expressive midrange detail and musical immediacy, while the three housing materials provide a combination of density, damping, and structural stability.

The X2 dynamic driver uses a Mylar diaphragm, copper voice coil, and rare-earth magnet system. L cushions position the drivers close to the ears, contributing to the RS1s focused and immediate presentation.

Tri-Wood Housings

The RS1s housings combine cocobolo, hemp, and maple. According to Grado, the different acoustic properties of these materials work together to produce a layered and controlled presentation.

Signature Gold Headband Assembly

The RS1 uses Grados Signature Gold headband assembly, the companys most refined mechanical platform within the Classic Series. Engraved aluminum-alloy gimbals, stainless steel height rods, and reinforced aluminum junction blocks improve structural stability and durability while maintaining controlled earcup rotation.

A genuine leather headstrap with contrasting white stitching provides cushioning, while an internal steel spring band lets you adjust the clamping pressure.

Signature Silver Cable and L Cushions

Grados Signature Silver cable is designed to reduce weight and improve flexibility. The standard version is terminated with a 3.5 mm plug and includes a removable 1/4″ adapter, while an XLR-terminated version is also available.

The RS1 is supplied with L cushions, which contribute to its focused and immediate presentation. Because Grados cushions also act as acoustic tuning elements, they can be changed to alter the fit, tonal balance, and presentation.
