A New Generation of Grado Sound
At the heart of the Signature S150 is an entirely new 44mm S driver, incorporating a paper-composite diaphragm inspired by the larger 52mm drivers found in the flagship HP100 SE and S950 headphones.
Developed specifically for the S150, this new driver delivers impressive clarity, detail and musical depth while preserving the natural warmth and engaging character that have made Grado headphones a favourite among audiophiles for generations.
Despite its open-back design, the S150 has been engineered to reproduce articulate, controlled bass alongside expressive midrange frequencies and detailed highs, creating a balanced and immersive listening experience.
Detachable Cables, Greater Flexibility
One of the S150's most welcome features is the inclusion of Grado's new Signature Bronze detachable cable.
Lighter, softer and more flexible than previous cable designs, the Signature Bronze cable provides greater convenience for everyday listening. Dual 3.5mm headphone connections allow easy cable replacement and flexibility in cable positioning.
The supplied cable features a 3.5mm connection with an included 6.3mm adapter, making the S150 compatible with a broad range of audio sources, from portable music players to dedicated headphone amplifiers and home hi-fi systems.
Contemporary Design Meets Classic Grado Character
The Signature S150 introduces a new single-piece acoustic housing, combining the familiar aesthetic of Grado's iconic open-back headphones with a more contemporary appearance.
Constructed from engineered ABS polymer with a refined matte-black finish, the new housing provides a lightweight yet durable foundation for the S150's acoustic performance.
Weighing just 220 grams, the headphones also feature a new padded leather headband, adjustable steel support band, redesigned gimbals and stainless-steel height rods.
Together, these refinements provide improved adjustability and comfort, making the S150 ideally suited to extended listening sessions.
The S150 ships with Grado's F cushions and is compatible with the wider range of Grado replacement cushions, allowing owners to further personalise both comfort and sound.
Premium Engineering, More Accessible Than Ever
With the Signature S150, Grado continues its tradition of refining headphone performance through thoughtful engineering rather than unnecessary complexity.
By combining driver technology derived from its premium Signature models with practical improvements in comfort, connectivity and design, the S150 offers an exciting new entry point into serious high-fidelity listening.
For anyone discovering Grado for the first time, or existing enthusiasts looking for a versatile addition to their collection, the Signature S150 is a noteworthy new arrival.
