Grado Labs Signature S550 Headphones
May 8, 2026Grado Wireless
When you snag your pair of Grado’s open-back GW100x headphones, you’ll discover a message on the box interior proudly proclaiming the company’s six-decade legacy as a family-run business in Brooklyn. The design of these headphones echoes our heritage, boasting a no-frills aesthetic with circular grills, a smooth black-leather headband, and a commitment to delivering exceptional sound.
Grado has introduced 44mm drivers, redesigned speaker housings, and support for the aptX Adaptive codec, enhancing the overall performance. However, the design philosophy for the GW100x prioritizes functionality over flamboyance, and we’ve maintained a stripped-back aesthetic that exudes an industrial, hard-edged feel. The lightweight design offers practical features like an in-built microphone for voice calls and robust up-and-down slider mechanism for easy adjustments, a choice between wired and wireless connections, and an impressive 46-hour battery life at 50% volume.
Perfect for at home listening, the GW100x delivers as expected from Grado, offering a rich and detailed audio experience. Whether used wirelessly or with the 3.5mm jack-equipped cable, the headphones excel in reproducing diverse musical genres with clarity and precision. If you prioritize top-notch audio in a quiet environment, the GW100x is worth considering, despite its unconventional design and features.
