1. What is the Grado Signature S550?
The Grado Signature S550 is the fourth model added to the Signature Series- the premier line of products from Grado Labs, where the best technologies and materials the company can craft are brought together.
What’s special: The S550 is the first headphone in the Signature series priced under $1,000 USD. Specifically, it’s $995 – $700 less than the Signature S750 released in October 2025. This move makes Grado’s high-end product line more accessible to a wider range of music enthusiasts.
2. The 50mm S2 Driver- Specially Tuned for the Wood Housing
The heart of the Signature S550 is the brand-new 50mm S2 dynamic driver- the same driver used in the higher-end S750 model. However, Grado has specifically tuned this driver to complement the Brazilian Walnut wood housing.
Instead of developing an entirely new driver architecture, Grado’s engineers focused on optimizing the interaction between the S2 driver and the wood housing. This method prioritizes sonic refinement over a specs race. The result is that the Signature S550 delivers a warmer and more forgiving sound compared to the S750, while still preserving the speed, detail, and immediacy – the characteristics that have defined the Grado sound for decades.
Grado states: “The S550 is designed for listeners seeking warmth, openness, and clarity without fatigue. It offers a more relaxed presentation while preserving the speed, detail, and immediacy that have long defined the Grado sound.”
3. Brazilian Walnut Wood Housing- No Two Are Alike
The aesthetic and acoustic highlight of the Signature S550 is its housings, entirely crafted from solid Brazilian Walnut wood.
Why wood? Grado has long favored wood housings for their unique resonance properties. Different woods influence sonic characteristics in subtle ways. On the S550, the driver is specifically tuned to work with the walnut housing, creating a warm, open, and natural sound.
Unique: Because they are made from real wood, each grain and pattern is unique. No two Grado Signature S550 headphones will be exactly alike. This is a special charm for those who appreciate individuality.
4. Design and Comfort
The Grado Signature S550 inherits several design features from its sibling, the S750:
New B Pads: Designed to sit flatter against the ears, distributing pressure more evenly for comfort during extended listening sessions. These pads are also compatible with the full range of other Grado pads, allowing for personalization based on preference.
Leather Headband Strap: Narrower than previous models, with a flexible metal frame inside, allowing it to conform to the shape of the head over time for a perfect fit.
Height Adjustment Rods: Made from stainless steel, ensuring durability and sturdiness.
5. Flexible Detachable Cable System
Like Grado’s more recent headphone models, the Signature S550 is equipped with a detachable cable system.
Connector: Each earcup uses a 4-pin mini XLR balanced connector.
Included Cable: It comes with the new Signature Silver cable, designed by Grado to be lighter, softer, and more flexible than previous cables. It terminates in a 3.5mm jack and includes a 6.3mm adapter for compatibility with a wide range of audio equipment.
Upgradability: With a standard connector, you can easily upgrade to higher-end cables from Grado or third parties in the future.
6. Signature Sound at a New Price Point
So, how does the Grado Signature S550 sound? According to Grado, it’s a refined combination:
Warm and Relaxed: Not pursuing a dry, “clinical” studio neutrality, the S550 delivers a warm, pleasant tonality that minimizes listening fatigue.
Detailed and Lively: Despite its warmth, the S550 retains Grado’s characteristic speed, detail, and immediacy. Acoustic, jazz, and orchestral tracks are reproduced with impressive space and texture.
Open Soundstage: The open-back design helps create a natural, airy soundstage where vocals and instruments are placed within a clear three-dimensional space.
With an impedance of 38 ohms and sensitivity of 112dB SPL at 1mW, the S550 is relatively easy to drive and performs well with various sources, from portable DAC/amps to traditional hi-fi headphone amplifiers.
