S750 joins the Signature line

The S750 headphones are latest addition to Grado’s acclaimed Signature Line. As the third model in the line, the S750 builds on the award-winning stature of the Signature HP100 SE and Signature S950, offering another entry point into Grado’s expanding Signature collection, while staying true to the company’s tradition of uncompromising craftsmanship and sound quality. The S750 features a new ground-up driver design and sees the introduction of a new cushion.

New S2 driver for a new sound signature

At the heart of the S750 lies the brand new S2 50mm driver, engineered from the ground up. Featuring a carbon fibre and paper composite diaphragm, paired with a lightweight copper-plated aluminium voice coil, this driver delivers a natural musical presentation with definition and dynamic range. The S2 driver design continues Grado’s commitment to class-leading sonics, ensuring the S750 captures the detail and character of every performance while offering a uniquely engaging listening experience.

Introducing the New Grado B cushion

Debuting with the S750 is the new Grado B cushion, a fresh approach to comfort and acoustic performance. Standard on the S750 and available separately as an accessory, the B cushion is compatible with all current Grado wired headphones.

Unlike traditional cushions, the B cushion shortens the distance between the driver and the ear and introduces a smaller interior opening to adjust balance. Eight precisely engineered slits improve airflow, opening up the soundstage while maintaining detail. The flat surface distributes pressure more evenly across the ear, educing fatigue and creating a distinct new feel for long listening sessions.

All-aluminium housing

The housing of the S750 is an all-aluminium construction, each one handcrafted in Brooklyn, NY. Despite its robust build, the S750 weighs just 460 grams, making it over 10% lighter than the HP100 SE while still delivering the premium feel and durability that defines the Signature Line.

Enhanced detachable cable system

The S750 continues the Signature tradition of detachable cables, first introduced with the HP100 SE. Supplied with a 6-foot cable terminated in a 6.35mm single-ended plug, the new Signature Gold braided design is softer, more durable, and lighter than before, while improved insulation also enhances flexibility.

Each cable connects to the housing via a 4-pin balanced mini XLR, providing compatibility with future detachable Grado cables. Options will include a variety of lengths, as well as balanced terminations such as 4-pin XLR and 4.4mm, enabling users to tailor their setup to personal preference and source equipment.

Comfort and durability refined

The headband assembly of the S750 mirrors that of the Signature HP100 SE and S950, with a few subtle refinements. Though slightly narrower, the leather headband retains 50% more padding than earlier Grado models, ensuring long-lasting comfort.

Engineered for reliability, the assembly incorporates engraved aluminium alloy gimbals, stainless-steel height rods, and reinforced aluminium junction blocks. The limited 105-degree rotation reduces wear while maintaining flexibility, improving both stability and long-term durability.
