Description
Featuring New S2 Drivers and Cushion Design
The Grado Signature S550 brings the core values of the Signature Line into a more streamlined and approachable form. Designed for listeners who value musical engagement as much as technical performance, the S550 delivers clarity, balance, and energy in a headphone built for long, immersive listening sessions.
At its heart, the S550 is tuned to preserve the immediacy and openness Grado is known for, while offering a refined presentation that remains natural and fatigue-free. From subtle acoustic details to dynamic passages, the S550 is engineered to connect you more directly to the music — not just the sound.
Driver Design & Engineering
The S550 is built around a newly engineered dynamic driver, developed to deliver a balanced and engaging presentation while preserving the speed and clarity that define Grado’s sound. Every element of the driver assembly has been carefully considered, allowing the S550 to reproduce fine detail and natural dynamics without sacrificing musical flow.
By focusing on control, responsiveness, and tonal accuracy, the S550’s driver delivers a sound that feels immediate and open, yet remains composed across a wide range of recordings. The result is a headphone that responds effortlessly to both subtle textures and more demanding passages, making it equally at home with intimate acoustic recordings and larger-scale performances.
Detachable Cables
The S550 features Grado’s detachable cable system, designed to improve flexibility, longevity, and overall usability while maintaining signal integrity. The lightweight cable construction offers increased pliability, reducing memory and improving comfort during extended listening sessions.
Detachable connections allow for easy replacement and customization, giving listeners the freedom to select alternative terminations or cable lengths to suit their system. Whether used in a traditional single-ended setup or paired with balanced amplification, the S550’s cable system is engineered to preserve the headphone’s natural clarity and dynamic response.
Cushions & Personalization
The S550 ships standard with Grado’s B cushions, offering a balanced combination of comfort, support, and acoustic performance. Designed to complement the headphone’s tuning, the B cushions provide a natural presentation that works across a wide range of music and listening styles.
For those who wish to further tailor their experience, the S550 is also compatible with Grado’s S, F, L, and G cushions. Each cushion style subtly influences both comfort and sound, allowing listeners to adjust fit, presentation, and spatial character to better suit their personal preferences. This flexibility makes the S550 easy to adapt — whether prioritizing long-term comfort, a more intimate presentation, or a broader soundstage.
"The B cushion offers listeners an option of how they experience Grado headphones. We’ve always engineered our drivers to achieve the best sound possible, but we understand that every listener enjoys a slightly different sound signature. With the S550, we’re giving users the flexibility to listen the way they want." — Richard Grado, Chief Operating Officer at Grado Labs
Comfort and Durability
The S550 features Grado’s proven headband design, engineered to provide long-term comfort and dependable durability. Its adjustable construction allows the headphones to sit securely while distributing weight evenly, helping to reduce pressure during extended listening sessions.
Built to withstand daily use, the headband assembly balances flexibility with strength, ensuring consistent fit over time without compromising comfort. Thoughtfully integrated into the overall design, it supports the S550’s focus on wearability, making it a headphone you can enjoy for hours at a time.
Hand Assembled in Brooklyn
Founded on a kitchen table in 1953, and working with wood for over a quarter century, Grado Labs has been perfecting the art of sonic reproduction every day since. The Signature S550 has traveled from workbench to workbench until ready for your ears. Every experience since that kitchen table has led to the creation of the Signature S550 headphone.
