Grado Labs, a Brooklyn-based manufacturer known for their award-winning headphones, has unveiled their latest flagship model, the Signature HP100 SE. This new offering pays homage to the pioneering HP1 headphones released in the early 1990s by founder Joseph Grado, a product considered by some to be the genesis of the high-end headphone market.

Design and Build

• Modern Homage: The HP100 SE blends classic Grado design with a contemporary aesthetic. The housings are individually machined from aluminum and finished in a stylish space grey, echoing the original Signature HP series while offering a modern touch.
• Detachable Cables (A First for Grado): For the first time in Grado's history, the HP100 SE features detachable cables. This allows for easier customization and replacement in case of damage. The included cable boasts a softer braided design for improved flexibility and reduced weight, terminating in a 6.3mm plug. Additional cable options with 4-pin XLR or 4.4mm balanced terminations and various lengths will be available for purchase in the future.
• Enhanced Comfort: Grado has redesigned the headband assembly for improved comfort during extended listening sessions. It features 50% more padding than previous models and utilizes a stainless steel band with adjustable height rods for a personalized fit that minimizes listening fatigue. The aluminum alloy gimbals with engraved Grado Labs logos and stainless steel height rods enhance stability and prevent disassembly.

• Open-Back Design: The open-back design provides a wide soundstage and a natural, spacious listening experience. However, it also means sound leaks out and ambient noise can be heard.
