GRADO Signature S750: The New Open-Back Reference with 50 mm S2 Drivers
Handcrafted in Brooklyn: Precision, Musicality, and Heritage
The Grado Signature S750 marks a new era for the legendary Signature line, introducing the brand’s new 50 mm S2 drivers, next-generation B Cushion earpads, and a precision-machined aluminum housing.
Handcrafted in the historic Grado Labs workshop in Brooklyn, New York, the S750 perfectly fuses artisanal craftsmanship with advanced acoustic engineering — redefining the balance between musical warmth, resolution, and comfort.
Key Features
New 50 mm S2 driver with hybrid carbon–paper diaphragm and aluminum–copper voice coil for fast, natural, and detailed sound.
Next-generation B Cushion earpads for improved tonal balance, extended soundstage, and all-day comfort.
Hand-machined aluminum housing for superior resonance control and lasting durability.
Lightweight design: 460 g (lighter than the HP100 SE).
Detachable Signature Gold cable — 12-conductor design with high-purity copper for exceptional signal integrity.
4-pin mini XLR connectors for easy cable replacement and future balanced upgrades.
Handcrafted in Brooklyn, NY by Grado artisans.
S2 Driver: The Heart of a New Generation
At the core of the S750 lies Grado’s new S2 50 mm dynamic transducer, developed from the ground up.
Its hybrid carbon–paper diaphragm provides the ideal balance between rigidity and speed, while the aluminum-copper voice coil enhances microdynamics and control even at high volumes.
The result is a presentation that’s wider, cleaner, and more detailed, yet retains the organic texture and warmth that define the Grado sound signature.
B Cushion Earpads: Comfort Meets Precision
The redesigned B Cushion delivers major acoustic and ergonomic improvements:
Smaller internal cavity brings the driver closer to the ear for a more natural tonal balance.
Eight precision-vented slits expand the soundstage and spatial imaging.
Flat, pressure-distributing surface minimizes fatigue during long sessions.
Enhanced comfort without compromising acoustic accuracy.
Machined Aluminum Housing
Each S750 earcup is precision-machined from solid aluminum, chosen for its combination of strength, mass control, and resonance damping.
Provides superior rigidity and sonic clarity.
Reduces unwanted vibrations and coloration.
Features a refined, high-end aesthetic with meticulous hand finishing.
Despite its solid construction, the S750 weighs just 460 g, offering a robust yet agile listening experience.
Signature Gold Cable (Detachable)
The new 12-conductor Signature Gold cable is detachable and built for both sonic purity and flexibility.
Low-capacitance, twisted geometry minimizes interference and signal loss.
Soft-touch jacket and improved strain relief ensure long-term durability.
4-pin mini XLR connectors enable future balanced upgrades (4.4 mm or XLR).
