The Signature S750 is the third model in Grado Labs' Signature Line, joining the Signature HP100 SE and Signature S950. It offers another entry point into Grado's expanding Signature collection, pairing a newly engineered driver and cushion with the hand-built construction that defines the range.
S2 Driver
At the heart of the S750 lies the brand new S2 50mm driver, re-engineered from the ground up. It features a carbon fibre and paper composite diaphragm paired with a lightweight copper-plated aluminium voice coil, delivering a natural musical presentation with definition and dynamic range. The S2 driver continues Grado's commitment to class-leading sonics, capturing the detail and character of every performance.
The New Grado B Cushion
Debuting with the S750 is the new Grado B cushion, standard on the headphone and compatible with all current Grado wired models. The B cushion shortens the distance between the driver and the ear and introduces a smaller interior pocket that redefines the acoustic balance. Eight precisely engineered slits improve airflow, increasing the soundstage while maintaining detail, and the flat surface distributes pressure more evenly across the ear to reduce fatigue during long listening sessions.
Enhanced Detachable Cable
The S750 continues the Signature Line tradition of detachable cables, first introduced with the HP100 SE. It is supplied with a six-foot Signature Gold cable terminated in a 6.3mm single-ended plug; the braided design is softer, more durable and lighter than before, with improved insulation for added flexibility. Each cable connects to the housing via a 4-pin balanced mini XLR, providing compatibility with present and future detachable Grado cables. Accessory cables are available in additional lengths and source terminations, including 4-pin balanced XLR and 4.4mm balanced single-ended.
Comfort and Durability
The housing of the S750 is an all-aluminium construction, each one handcrafted in Brooklyn, New York. Despite its robust build it weighs just 460 grams, over 10% lighter than the HP100 SE. The headband assembly mirrors that of the Signature HP100 SE and S950 with subtle refinements; though slightly narrower, the leather headband retains 50% more padding than earlier Grado models. The assembly incorporates engraved aluminium alloy gimbals, stainless-steel height rods and reinforced aluminium junction blocks, with a limited 105-degree rotation that reduces wear while maintaining flexibility.
