Grado Signature HP100 SE Review | 93 Data compared

The Grado Labs Signature HP100 SE Headphones ($2,495) represent a bold, landmark shift for the historic Brooklyn manufacturer, earning the reviewer's highest recommendation and a Writers Choice Award. Released to celebrate the centennial birth anniversary of founder Joseph Grado, this flagship model completely eliminates wood to dramatically reduce sonic colorations across all frequencies. It introduces an all-aluminum hand-machined housing, more stable steel gimbaled ear cup supports, and a newly engineered 52mm paper and carbon fiber driver matched to an exceptionally tight.04dB. Notably, this is the very first Grado headphone to feature a detachable cable system, utilizing a flexible 12 solid-core copper wire bundle with 4-pin XLR balanced compatibility. For added physical comfort during extended listening sessions, the redesigned headband boasts 50% more leather padding. Sonically, the chief pros of the HP100 SE are its unmatched transparency, absolute neutrality, and seemingly unlimited dynamic range that operates entirely without distortion, even at bombastic volumes. The reviewer praises its blistering driver speed, precise imaging, expansive three-dimensional soundstage, and extraordinarily deep bass reproduction. However, a notable con is its "garbage in, garbage out" nature;...

The Grado Signature HP100 SE is a high-end, open-back dynamic headphone priced at $2,495 that pays homage to the brand’s historic 1980s and 1990s signature design while introducing highly anticipated modern upgrades. Handcrafted in Brooklyn, it features a unique 52mm paper composite dynamic driver and stands out as the first Grado model to offer fully detachable dual-entry 4-pin mini XLR cables. Sonically, the headphones deliver exceptional midbass punch, top-shelf vocal clarity, and an incredibly expansive, wide horizontal soundstage that competes with the best high-end options in its price tier. The package also provides excellent value and tuning flexibility by including both over-ear G-style and on-ear F-style earpads, which noticeably alter the overall sound signature. Despite its superb technical performance, the HP100 SE suffers from notable design and sonic drawbacks. Its hefty all-metal build weighs over 500 grams, and when paired with thin headband padding, it creates uncomfortable hotspots on top of the head during extended listening sessions. The included stock cable is also heavily criticized for being cumbersome, stiff, and retaining its shape awkwardly. From an audio standpoint, the headphone...

The Grado Signature HP100 SE are a premium pair of hand-assembled, hard-wired, open-backed over-ear headphones priced at £2,795 / $2,495. Built to celebrate founder Joseph Grado's 100th birthday, they feature a major design shift for the brand by introducing detachable cables alongside newly engineered 52mm paper composite speaker drivers. Performance is the headset's standout attribute, offering an exquisitely poised, neutrally balanced, and lavishly detailed soundstage across a massive frequency range of 3Hz to 51kHz. They deliver deep, tightly controlled bass and dynamic, energetic rhythms without ever sacrificing musicality or forensic detail. Despite their brilliant acoustic engineering, the headphones suffer from low perceived physical value for the hefty price tag. While they are lighter and more comfortable than previous models due to a redesigned braided cable and 50% more headband padding, they still use rather basic raw foam "G" and "F" cushion earpads. Furthermore, they utilize an outdated, "agricultural" friction pole arrangement for size adjustments that makes them a poor fit for anyone with a smaller head. They are also limited by a lack of immediate cable termination options, shipping only...

The Grado Signature HP100 SE is a flagship open-back dynamic headphone built to honor the brand's founder, Joseph Grado. It features a sleek, space-gray aluminum alloy housing and 52mm drivers. It is also the first Grado headphone to use detachable cables. The reviewer notes that the headphone requires a burn-in period of at least 15 hours. Out of the box, the sound can be thin and overly sharp. On the positive side, the headphone offers amazing high-resolution detail retrieval and an impressively wide soundstage. It has high sensitivity, which makes it very easy to drive with portable devices. However, there are a few drawbacks. The headphone's sound can be bright and aggressive. This can cause user fatigue during long listening sessions. It is also highly sensitive to cables. Pairing it with the wrong cable can quickly ruin its tonal balance. Finally, the minimalist packaging includes zero extra accessories like a carrying pouch.

The review for the Grado Signature HP100 SE open-back headphonesGo on MusicTech highlights them as a brutally honest, £2,800 reference tool handcrafted in Brooklyn. Built with a 52mm dynamic driver, these flagship headphones are designed specifically for critical listening and studio mixing rather than tracking, as their open-back architecture naturally leaks sound. The reviewer notes that they deliver a slower, more deliberate listening experience that forces the user to confront every hidden quirk, imperfection, and raw truth within a recording. Pros include an incredibly expansive, natural soundstage, spatial realism, and a level of micro-detail retrieval so sharp it can unearth systemic distortions in connected amplifiers that other headphones mask. Furthermore, they feature highly versatile, interchangeable ear cushions; the G-cushion maximizes speed and spatial separation, while the alternative B-cushion brings the driver closer to soften the top end and add low-frequency weight. Conversely, the cons focus heavily on their unforgiving nature, which makes them mentally taxing to wear over long sessions, especially with intense audio material. Additionally, they completely lack isolation and are prohibitively expensive for general consumers, making them poorly...

The Grado Signature HP100 SE is a premium open-back dynamic flagship headphone released to honor Joseph Grado’s 100th birthday, priced at $2,495. It marks a major design shift for Grado Labs, introducing a completely new 52mm driver with a paper composite cone, a lighter copper-plated aluminium voice coil, and a space grey machined aluminium housing. Crucially, it is the first Grado model to implement a detachable cable system using 4-pin mini XLR connectors. It also sports a revamped stainless steel headband featuring 50% more padding than classic models, plus custom-engineered gimbals that limit housing rotation to 105 degrees to minimize structural wear. Performance-wise, the headphone excels with an expansive, immersive soundstage that accurately reflects original recording venues, alongside blistering transient speed and impactful, deep, linear sub-bass response. Its exceptional high efficiency means driving it is effortless, though users will need clean amplification with a low noise floor to maximize performance. However, its transparent reference nature makes it highly unforgiving of poor source equipment or low-quality electronics. Additionally, its prominent, "hot" midrange accentuates recording flaws, making it less suitable for imperfect...

The Grado Signature HP100 SEGo, awarded five stars by Hi-Fi Choice, is a reference-quality, open-back headphone featuring a redesigned, comfortable stainless-steel headband and a highly efficient 52mm paper-composite driver. As a first for the brand, these flagship headphones feature detachable cables and a detailed, refined sound profile with exceptional midrange presence, intended for quiet listening environments. While praised for its performance, the high-end, detailed sound is packaged without any passive noise isolation due to its open-back design. The main drawbacks are the lack of ambient noise isolation and a premium price tag, making them a luxury investment.
