S2 Driver – The Core of Acoustic Innovation
At the heart of the Grado Signature S750 lies the newly engineered S2 driver, developed to deliver a more natural and finely detailed sound profile. The 50-mm diaphragm combines carbon fiber and paper composite materials to balance rigidity and lightness. Together with a copper-clad aluminum voice coil, this structure aims to achieve a wide dynamic range, fast transient response, and a balanced tonality – hallmarks of the Signature Line that are now even more refined.
B-Cushion – Comfort Meets Tonal Balance
The newly designed B-Cushion plays a crucial role in both comfort and acoustic presentation. Its slightly shallower profile positions the driver closer to the ear, resulting in a more immediate soundstage and enhanced spatial imaging. Eight precision-cut vents improve airflow, widening the perceived stage while maintaining clarity. The pressure distribution is also optimized, making extended listening sessions more comfortable. Grado plans to make the B-Cushion available as an optional accessory for other headphone models as well.
Detachable Cable System and Connection Flexibility
As with the Signature HP100 SE, the new S750 features detachable cables for easy replacement and customization. The standard 1,8-meter Signature Gold Cable uses twelve conductors and improved insulation for low resistance and high flexibility. The headphone connects via 4-pin Mini-XLR sockets on both earcups, allowing users to switch between cables for different setups. Grado offers optional balanced cables with 4,4 mm Pentaconn or 4-pin XLR connectors for high-end amplifiers and DACs.
Design, Craftsmanship, and Materials
The S750’s housing is crafted entirely from solid aluminum, machined and hand-assembled in Brooklyn. Despite its robust construction, the model is about ten percent lighter than the HP100 SE. It features CNC-milled aluminum gimbals, stainless-steel rods, and a leather headband with 50 % more padding than previous models. The goal, according to the manufacturer, was to increase long-term stability while minimizing wear by limiting rotational stress. The result is a headphone that feels as refined as it sounds.
Price and Availability
According to Grado Labs, the Grado Signature S750 will be available from November 2025 through authorized retailers. The recommended retail price is expected to be around € 1.695,-. Optional replacement cables and the new B-Cushion will also be sold separately.
Conclusion
The Grado Signature S750 continues the brand’s legacy of blending traditional craftsmanship with modern acoustic research. The combination of the new S2 driver, refined B-Cushion, and modular cable design demonstrates Grado’s commitment to evolving its sound while preserving its unmistakable character. For enthusiasts of open-back dynamic headphones, the S750 represents a highly promising addition to the high-end segment.
