At the heart of the HP100 SE is a completely new speaker design. In considering the attributes of anew 52mm driver, Grados goal was to deliver a speaker that produced excellent highfrequency resolution, midrange smoothness and bass energy with low distortion, resulting in a voicingthat is musically and harmonically correct.

A new paper composite cone was chosen, alongside a powerful high flux magnetic circuit using rare earth alloys, and a new voice coil made from lightweight copper-plated aluminum. This new magnetic circuit coupled with the voice coil produces excellent dynamics and transient response, along with a highly refined sense of space, soundstage and image.

Modern housing design with detachable cables
Honoring the recognizable heritage of the original Signature HP1/2/3 headphone designs but with amodern feel, the housings are individually machined from specially treated aluminum with theproduct name neatly engraved on the face. The HP100 SE arrives in a a stylish space grey finish.

HP100SE

The HP100 SE is the first Grado model to feature detachable cables. A departure from the cablecurrently employed on the Statement Series, it has been engineered to a softer but durable braidedfinish, with cable insulation that improves flexibility and decreases the overall weight of the cable.

Terminated with a 6.3mm plug, it connects to each housing via a 4pin mini XLR plug. Additional detachable cable options such as 4pin XLR termination, 4.4mm balanced termination, and various cable lengths, available in the future. This allows for the cable to be changed based on customer needs for source side termination and cable range.

Headband assembly redesign

The HP100 SEs headband assembly has changed from the classic Grado models. Designed for comfortduring long listening session, the new headband features 50% more padding than previous Gradodesigns, with a stainless steel band and height rods that can be adjusted for the perfect fit to minimizelistening fatigue.Grado Labs engraved gimbals are made from an aluminum alloy, and the stainless steel height rodenhances the stability of the point where they meet. The height rod is also designed to not slide outof the junction block if the zinc alloy end caps become dislodged. This mechanism limits housingrotation to 105-degrees to reduce wear and tear.
