Description
The Grado Signature S750 is an open-back, over-ear headphone designed and hand-assembled in Brooklyn, NY. It represents an entry point into Grado’s Signature Line, combining updated driver technology with a lightweight metal construction and a modular cable system.
The S750 uses Grado’s newly developed S2 dynamic driver, built with a carbon fiber and paper composite diaphragm and a copper-plated aluminum voice coil. The driver design focuses on controlled movement, low mass, and consistent response across the frequency range.
A new Grado B cushion is included, designed to position the driver closer to the ear while improving airflow and overall comfort. The cushion shape and venting are intended to influence soundstage presentation and reduce pressure during extended listening sessions.
The headphone housing is constructed from machined aluminum, providing rigidity while keeping overall weight low. An updated leather headband with added padding is used for improved comfort and durability.
The S750 is supplied with a detachable Signature Gold braided cable, connected via 4-pin mini XLR. This allows for cable replacement and compatibility with alternative cable configurations. The headphones retain Grado’s open-air design, allowing sound to interact naturally with the surrounding environment.
The S750 is intended for home and critical listening applications where open-back performance and modular construction are preferred.
