Compare Audio-Technica ATH-ADX7000 vs Grado Signature S750

The hard case, two cables, two pad sets, and cable pouch create a generous flagship package. Cable quality is the main element that keeps the bundle from feeling universally luxurious.

The package is sparse for the asking price. Reviewers specifically criticized the lack of a case and the absence of multiple cable choices in the box.

The detachable A2DC connection is secure and easy to use for some, but proprietary compatibility limits affordable replacement and cable-rolling choices.

Detachable mini-XLR cabling is widely treated as a major Grado improvement. Swappable lengths and balanced terminations make the S750 far easier to adapt to different amplifiers and listening positions.

The bendable, notched headband offers unusually direct control over fit and clamp. Reviewers note that these adjustments can also change the tonal balance.

The familiar friction-rod headband adjustment works effectively, but its presentation divides opinion. One reviewer preferred its simple function to ornate mechanisms, while another thought it felt crude for the price.

Headband comfort is the most divisive physical issue. Some find the thin dual-rod structure surprisingly comfortable, while others report fast hotspots and insufficient padding.

Extra headband padding is generally seen as a meaningful improvement over older Grados. Most reports are positive, but one reviewer still found the padding meager and insufficient for the price.

At roughly 270–275 grams, the headphone is exceptionally light for the flagship class and often seems to disappear on the head. This is one of the most consistently praised aspects of the design.

At about 460 g, the S750 is lighter than some Signature siblings but still feels heavy to several reviewers. The reduced mass helps versus larger models, yet weight can undermine stability and long-session comfort.

Clamp is usually secure and adjustable, with several reviewers finding it well judged. Large- and small-head experiences differ, and clamp changes can affect both comfort and treble balance.

Clamp is inconsistent across head shapes rather than universally comfortable. One reviewer found it overzealous and tiring, another described the design as firm, while another thought the fit was too loose.

At extremely high test levels, one reviewer measured and heard more harmonic distortion than desired.

High-volume behavior is mixed: some listeners heard clean, glare-free treble at significant levels, while another found the brightness increasingly harsh as volume rose. The result appears especially dependent on recording quality and treble sensitivity.

The lightweight frame can remain secure even during exaggerated head movement, according to the one review that directly tested stability.

Stability depends heavily on fit and movement. The reinforced hardware is described as secure, but one wearer found the headphones would not stay put while moving their head at a desk.

Both velvet and Alcantara pads are soft and useful, with meaningful changes to bass, treble, openness, and intimacy. Circular openings and shallow depth can cause ear contact for some listeners.

The new B cushions improve comfort for some listeners but are strongly fit-dependent. They can distribute pressure well, yet the flat on-ear foam felt poorly fitting or uncomfortable to others.

Desktop connectivity is well covered by 6.3mm and balanced XLR cables, but the proprietary cup connector narrows aftermarket choices. The headphone is built around wired hi-fi systems rather than broad device compatibility.

Mini-XLR connections and optional cable lengths or balanced terminations give the S750 unusually flexible wired connectivity. Reviewers liked being able to tailor the cable setup to different sources and room layouts.

Low mass and roomy pads make long sessions easy for many listeners, including glasses wearers. Comfort is not universal because the dual-rod headband can create hotspots and circular pads may touch the ears.

Long-session comfort is the biggest point of disagreement. Some listeners wore the S750 for hours comfortably, while others found the on-ear pressure, foam, weight, or fit tiring within a short period.

The 490-ohm design rewards capable amplification, often gaining fullness, dynamics, bass texture, and spatial depth from stronger desktop or OTL chains. It can reach volume from modest sources, but several reviewers say underpowered gear sounds flat or thin.

The S750 is not uniformly source-agnostic: several reviewers heard clear gains with capable amplification, while one pairing lost clarity and openness. Good amplification can unlock more resolution, but system matching matters.

As expected from a fully open-back design, sound leaks into the surrounding room.

Sound leakage is an unavoidable downside of the open-back design and is serious enough to rule out many shared or public spaces. Quiet private listening is the intended environment.

The $3,499 price is the clearest barrier, and several reviewers question whether the physical luxury or technical gains justify it. Supporters argue the rare bass-plus-space combination makes sense for committed flagship buyers.

Value depends on what you prioritize: $1,695 is repeatedly called expensive, yet several reviewers think the sonic performance competes above its price class. Buyers paying for comfort, accessories, or luxury finish may find the equation less convincing.

Bass is the headline strength: unusually weighty, punchy, textured, and controlled for an open-back design. Sub-bass extension and pad behavior vary, and one critical review found the Alcantara bass loose and woolly.

Bass is generally tight, articulate, and well controlled rather than boosted for impact. Most reviewers call it lean or restrained for bass-heavy music, though one heard unusually deep, powerful sub-bass when the recording demanded it.

Midrange is usually clear, natural, and musically engaging, with vocals often well placed and tangible. A few reviewers hear recession, bloom, or less realistic tone than the strongest competitors.

Midrange performance is a standout across the board, with vocals described as vivid, tangible, crisp, and highly intelligible. Acoustic instruments also benefit from strong presence and clean articulation.

The fully open design offers little isolation and works best in a quiet room.

The open-back construction offers little practical isolation from noisy surroundings. It is better suited to quiet home listening than portable use in busy environments.

Cable feedback is sharply mixed. Several reviewers call the stock leads stiff, unwieldy, or highly microphonic, while one praises their quality and others mainly value the included balanced and single-ended options.

The Signature Gold cable is lighter and softer than older Grado designs, but cable ergonomics remain divisive. Critics still found it heavy, stiff, or awkwardly sized for common listening setups.

The case and presentation often feel flagship-grade, but the headphone itself does not always communicate luxury through heft or ornamentation. This understated approach appeals to function-first listeners and disappoints those expecting visual drama.

The aluminum construction can feel appropriately premium, but luxury impressions are not unanimous. One reviewer thought the materials justified the positioning, while another said the pads and headband did not feel luxurious at all.

Most listeners hear abundant detail and clean nuance without the usual sharp, analytical fatigue. A minority finds the presentation veiled or less resolving than similarly priced alternatives.

Fine detail retrieval is one of the most consistent strengths, revealing low-level textures, room cues, vocal nuances, and layers in familiar recordings. The presentation is highly informative without always becoming clinical.

The dominant impression is a balanced, natural, warm-neutral tuning that avoids the older Audio-Technica harshness. Pad choice, anatomy, and amplifier pairing can still shift the balance considerably.

Reviewers who focused on tonal accuracy heard a lifelike, uncolored, and convincing balance with precise timbre. The S750 favors faithful presentation over added warmth or bass emphasis.

Reviewers generally praise the rigid magnesium construction and precise mechanical execution, especially given the unusually low weight. A few feel the plastic joints and shared chassis language do not look expensive enough for a flagship.

Build quality is usually a strength, thanks to aluminum construction, solid hardware, and careful finishing. Most reviewers describe it as rugged or beautifully built, although one felt some headband details looked and felt cheaper than expected.

This is a desk-bound open-back headphone that expects a serious amplifier and leaks sound, making it a poor travel companion despite the protective case.

These are poor travel headphones: the open-back leakage, substantial weight, and insecure movement reported by some listeners work against commuting. Their strengths are much better suited to stationary home listening.

Recommendations are strong for listeners seeking warm-neutral open-back sound, exceptional bass, and a spacious presentation. More critical reviewers advise auditioning first because comfort, treble, and value are unusually personal.

Recommendations are strong for dedicated audiophile use, especially for listeners who prize detail, openness, and spatial precision. Fit, source matching, and price make an audition advisable before buying.

The included velvet and Alcantara pads function as meaningful tuning tools rather than simple replacements. Preferences differ widely, but the flexibility is considered valuable.

The stock B cushions are not the only fit option. Compatibility with Grado G, F, and L cushions gives owners a practical route to change how the S750 sits on the head.

The restrained industrial look is widely appreciated for function and precision rather than flash. Some buyers may find it too ordinary or too similar to less expensive Audio-Technica models.

The industrial Grado look remains distinctive, with several reviewers praising its retro, minimalist, or elegant execution. A dissenting view felt the physical appearance did not match the premium price.

Images are usually well defined laterally and through depth, with strong layering and three-dimensional placement. A few listeners find localization slightly floaty or less precise than top competitors.

Imaging is exceptionally precise, with stable placement and clear localization across the stage. Reviewers repeatedly describe instruments and voices as easy to position in a convincing three-dimensional space.

Most reviewers find the overall sound engaging, natural, and technically accomplished, especially for bass-heavy music and immersive listening. A smaller group considers it colored, congested, or insufficiently refined against cheaper competitors.

The S750 is consistently praised for exceptionally revealing, natural sound with strong musical engagement. Even the more critical takes on fit and hardware still describe the listening performance as a major strength.

The stage is consistently described as open, spacious, and often holographic, with strong depth and lateral definition. Some listeners find it more intimate than expansive or slightly behind the very widest competitors.

A broad, open soundstage is one of the S750’s defining strengths, often described as huge, airy, lifelike, or extending well beyond the earcups. One reviewer found the stage less expansive, but still accurate and breathable.

Treble opinions range from exceptionally clean, smooth, and non-fatiguing to peaky, sibilant, or incomplete around specific bands. Velvet is usually safer, while Alcantara often adds more energy and articulation.

Treble is detailed, airy, and extended, but opinions depend on tolerance for brightness. Several reviewers found it controlled and clean, while others warned that hot recordings or louder listening can make the upper range harsh.

Punch, transient speed, attack, and decay are widely praised, giving drums and bass unusually physical impact for an open-back dynamic headphone. Even positive reviewers note that it is not the absolute slam champion in every comparison.

The S750 handles both large dynamic swings and subtle microdynamics with unusual speed and control. Rhythm, transient attacks, and changing intensity stay composed even in dense music.

Enthusiasm is high across most sources, with many reviewers describing long, absorbed, emotionally engaging sessions. The few dissenting voices still acknowledge interesting qualities but do not feel the complete experience lands.

Overall satisfaction is high because the S750 repeatedly delivers memorable, engaging sound. The strongest reservations center on physical comfort and premium-price ergonomics rather than the core audio performance.

Complex arrangements are usually easy to follow, with instruments staying distinct and layered across the stereo field. This separation remains strong even when the bass is elevated.

Complex mixes stay exceptionally easy to untangle, with instruments and voices given clear space and localization. Dense orchestral, jazz, and rock passages remain layered rather than collapsing together.

Its slim matte-black profile is unusually discreet for a flagship. The design favors quiet precision over decorative luxury.

The S750 keeps Grado’s recognizable identity while cleaning up the presentation into a more modern, minimalist profile. The look is distinctive without becoming ornate.

With the right music and amplifier, the presentation can feel enveloping, holographic, and emotionally absorbing. This immersive quality is closely tied to the headphone’s openness and bass weight.

With the right source, the S750 can sound deeply immersive as well as analytical. Its vivid vocals, speed, and spacious presentation can make well-recorded music feel immediate and involving.

One publication gave the S750 a Product of the Year Award before its full review, reflecting unusually strong enthusiasm for its sonic performance. That recognition reinforces how highly its sound was regarded there.

The rigid metal or hard-shell case is repeatedly praised as protective, purposeful, and worthy of a flagship unboxing.

One reviewer explicitly praises the driver matching alongside the overall frequency response.

The restrained swivel range and reinforced metal hardware are designed to reduce wear over time. Reviewers discussing the assembly viewed it as rugged and well suited to regular use.

The limited 105-degree cup rotation is presented as a sensible durability choice, preserving useful flexibility while reducing wear. It favors controlled movement rather than full swivel freedom.

The S750 responds well to external EQ, with one reviewer adding low-end weight through Roon without damaging speed or articulation. That makes subtle tonal correction more viable than on some earlier Grados.

One reviewer wearing glasses found the fit comfortable and fatigue-free for hours, unlike earlier ADX models.

Practical portability is poor despite the detachable cable. Open-back leakage, weight, and the lack of suitability for noisy environments keep the S750 focused on stationary listening.

Owners can swap the stock B cushions for other compatible Grado pad shapes to change fit. That flexibility is useful for listeners who do not get along with the default on-ear geometry.

Volume can be adequate from modest dongles and low-power DAC/amps, though reaching volume is not the same as getting the fullest tonal and dynamic performance.

The raw foam pads can hold noticeable body heat. That may become uncomfortable during warmer or more active use, even though the headphone is primarily intended for stationary listening.
