Grado Labs Signature S750

Grado Labs Signature S750

October 15, 2025, Brooklyn, NY - Grado Labs, world-renowned designer and manufacturer of award-winning headphones, announces the launch of the Signature S750 headphones, the latest addition to its acclaimed Signature line. The third model in the series, the S750 builds on the award-winning success of the Signature HP100 SE and Signature S950 and offers a new entry into Grado's growing Signature collection, while staying true to the company's tradition of uncompromising craftsmanship and sound quality. The S750 has a completely new driver design and features a new cushion.

S2 driver presents new sound signature

At the heart of the S750 is the brand new S2 50 mm driver, which has been completely redesigned. Featuring a carbon fiber and paper composite diaphragm and combined with a lightweight, copper-plated aluminum voice coil, this driver delivers natural musical reproduction with definition and dynamic range. The S2 driver design continues Grado's commitment to industry-leading sound quality and ensures that the S750 captures the detail and character of each performance while providing a unique, engaging listening experience.

Improved detachable cable system

The S750 continues the tradition of detachable cables first introduced with the HP100 SE. The new Signature Gold braided cable comes with a 1.8-meter cable with a 6.3-mm single-ended plug and is softer, more durable and lighter than before, while improved insulation increases flexibility.

Each cable connects to the headphone housing via a 4-pin balanced mini-XLR, making it compatible with current and future detachable Grado cables. Accessory cable options include additional lengths, as well as source connectors such as 4-pin balanced XLR and 4.4 mm balanced single-ended, allowing users to customize their setup according to personal preference and source equipment.

Introducing the new Grado B cushion

With the S750, the new Grado B-cushion makes its debut, a new approach to comfort and acoustic performance. The B-cushion comes standard with the S750 and will soon be available as an accessory. It is compatible with all of Grado's current wired headphones.

The B-cushion shortens the distance between the driver and the ear and features a smaller inner pocket that redefines acoustic balance. Eight precisely designed slots improve airflow, enhancing the soundstage while maintaining detail. The flat surface distributes pressure more evenly across the ear, reducing fatigue and creating a distinct new feeling for long listening sessions.

Refined comfort and durability

The housing of the S750 is made entirely of aluminum and is handcrafted in Brooklyn, New York. Despite its rugged construction, the S750 weighs only 460 grams, making it more than 10% lighter than the HP100 SE, but still offering the premium feel and durability characteristic of the Signature Line.

The S750's headband is similar to that of the Signature HP100 SE and S950, with a few subtle refinements. Although the leather headband is slightly narrower, it has 50% more padding than previous Grado models, ensuring long-lasting comfort.

Designed with reliability in mind, the construction includes engraved aluminum alloy gimbals, stainless steel height adjustment rods and reinforced aluminum connecting blocks. The limited 105-degree rotation reduces wear while maintaining flexibility, providing both stability and long-term durability.
