Grado Signature S750

Grado Signature S750 – Premium headphones with new S2 driver and advanced acoustic design
The Grado Signature S750 is the latest addition to the acclaimed Signature series and builds on the legacy of models such as the Signature HP100 SE and Signature S950. As the third model in the series, the S750 offers a new entry point into Grado's premium collection, while maintaining the company's tradition of uncompromising craftsmanship and sound quality. The headphones introduce both a completely new driver design and a new type of ear pad.

At the heart of the S750 is the newly developed S2 driver—a 50 mm unit designed from the ground up. With a composite carbon fiber and paper cone, combined with a lightweight copper-plated aluminum voice coil, the S2 element delivers a natural and detailed presentation with excellent dynamics. Each driver is matched with high precision to ensure a consistent and engaging listening experience that meets Grado's high standards.

The housings are made of solid aluminum, handcrafted in Brooklyn, NY. Despite its robust construction, the S750 weighs only 460 grams—over 10% lighter than the HP100 SE—while offering the same premium feel and durability that characterizes the Signature Line.

Introducing the Grado B Cushion
The S750 introduces the all-new B cushion, designed to improve both comfort and acoustic performance. It reduces the distance between the driver and the ear, and the smaller internal chamber creates a more defined tonal balance. Eight precision slots improve airflow and increase detail reproduction, while the flat damping surface distributes pressure evenly and reduces listening fatigue. The B cushion is compatible with all current wired Grado models.

Improved detachable cable
The S750 continues the Signature series tradition of detachable cables and comes with the new Signature Gold 6-foot cable with improved durability, flexibility, and isolation. The cable connects via 4-pin mini-XLR, providing future-proof compatibility with upcoming Grado cables. Available accessories include different lengths and balanced variants such as 4-pin XLR and 4.4 mm.
