Grado Signature HP100 SE Headphones

A Tribute to Innovation and Legacy

Honoring the legendary HP1 model crafted by Joseph Grado, the HP100 SE is a Special Edition release marking his 100th birthday. As a pioneer in high-fidelity audio, Joseph Grado set an industry benchmark in the early 1990s, and the HP100 SE continues his legacy with cutting-edge enhancements.

"Though Uncle Joe left us a decade ago, his spirit continues to inspire Grado Labs," shares John Grado, CEO and nephew of the founder. True to Grado’s philosophy, the HP100 SE balances heritage and innovation, delivering an unmatched listening experience.

Advanced Driver Technology

At the core of the HP100 SE is an all-new 52mm dynamic driver, meticulously designed to produce crystal-clear highs, lush mids, and deep, controlled bass with minimal distortion. This innovation features:
✔ Paper composite cone for natural tonal balance
✔ Rare-earth magnet system for precise control
✔ Copper-plated aluminum voice coil for speed and transient response

Together, these refinements create an immersive soundstage, ensuring every note is rendered with accuracy and depth.

Precision-Engineered Housing & Detachable Cables

Hand-machined from aluminum alloy, the ear cups maintain the signature aesthetic of their predecessors, with a striking engraved model name and a refined space grey finish for a sleek, modern look.

Grado introduces detachable cables for the first time in this series. The 12-conductor braided cable minimizes weight for added comfort and superior signal transmission. Designed for modularity, it connects via a 4-pin mini XLR to the ear cups, with a 6.3mm plug at the source—offering flexibility for future cable upgrades.

Enhanced Comfort with Redesigned Headband

To support extended listening sessions, the HP100 SE features a newly reengineered headband with 50% additional padding. A stainless steel band with adjustable height rods ensures a secure yet comfortable fit.

✔ Engraved aluminum alloy gimbals for added stability
✔ Restricted cup rotation (105 degrees) for prolonged durability
✔ G-Type ear cushions designed for optimal sonic immersion
