Look & Feel
Those familiar with Grado headphones will find parts of the S750 similar to other products from their signature series, the S950 and HP100 SE. The construction of the S750 uses an aluminum frame, the same as the other signature series headphones, but it is significantly lighter. The headband is also thinner, but still has the same retro-style yokes that pretty much all Grado headphones have. If the S750 didn’t say “Grado” on the grilles, you would still be able to tell who the manufacturer is thanks to these key components.
The S750 also features Grado’s new B-cushion earpads, which I was surprised to see were flat cushions, making the S750 an on-ear headphone out of the box. This had a big impact on my listening, as I had a hard time adjusting to this fit. My ears were pressed against my head, and felt very fatigued only after a short time being worn.
Design
The Grado Signature S750 is built around a newly engineered S2 50 mm dynamic driver that uses a carbon fiber-and-paper composite diaphragm paired with a lightweight copper-plated aluminum voice coil, delivering detailed and dynamic sonic performance. These are relatively easy headphones to drive, but a DAC/Amp is recommended to push the sound to its potential. A Chord Mojo 2 and Fiio K13 R2R were used for this review.
Soundstage
While it’s not the most open and dimensional space, the soundstage on the S750 offers a reliably accurate stereo environment. The left and right channels are separated with tons of breathability. It allows the sound to exhibit a clear width at all times, rarely ever featuring instruments in the middle of your head. Nothing about the spatial imaging is solidified, but the overall headspace appears close. Performances appear at the sides of your head, but don’t completely wrap around you.
This isn’t a holographic soundstage in any way, but the precision of the sound allows for its own immersion. I would go as far as to call this a linear soundstage, but in a non-restrictive sense. Spatial positioning is strict, but each layer is so separated and articulated that it doesn’t matter that its reach isn’t too significant. There’s plenty of room for busy orchestral tracks or jazz ensembles to pinpoint each element with clear localization without resorting to thin airiness. Instruments are tall and full, even when openness is sometimes lacking.
Low End
This is not a bass-centric sound profile, and the S750 isn’t pretending it is. What’s there in the low end is clear and balanced, but it doesn’t deliver any significant tonal oomph. It’s more of a natural timbre that’s pleasantly reserved in its presentation. I wouldn’t choose the S750 to listen to any synthwave or pulsating electronic tracks, but for simple bass guitar note resonance, there’s enough smooth detail to bite on. Everything about the lows is still tucked underneath the midrange, without any noticeable sub-bass presence to lift it up, but there’s a surface area that gives the frequencies fullness in the mix.
Mids
The midrange has a ton of energy coming out of the S750. It features the most transparency and realism as well, making these frequencies extra lush and vivid. It’s projected outward with significant drive, allowing the core of most instruments to strike hard across the sound signature. The tips of piano keys have a strong impact, while acoustic plucks ring out with clean resolution. Vocals are a huge standout, ensuring crisp, dominant male and female voices that showcase the S750’s roominess and vigor. There’s a weight behind each note, and it makes the S750 feel the most complete.
Highs
The Grado S750 continues its strong drive into the treble, where the headphones project a bright timbre without causing any peakiness or harsh tones. If you favor a softer high end, the S750 might not go down easily, but if your ears can forgive spurts of treble heat, then you’re rewarded with clear definition. It never gets to a point where the tone is unforgiving, but its rawness can easily drive some listeners away. The S750 doesn’t feature a ton of height either, which gives the sound signature even less space for the highs, so they’re more concentrated. I think the highs are controlled well enough to satisfy, exhibiting an elegant ring that extends and tapers off.
Summary
The Grado Signature S750 is a distinctive entry in Grado’s lineup, blending classic design elements with a new driver system that delivers clarity, energy, and strong midrange realism. While its on-ear fit and leaner low end may not appeal to bass-focused listeners or those sensitive to on-ear pressure, the S750 rewards with excellent vocal presence, articulate imaging, and a bright, expressive treble. If you value transparency, speed, and separation over warmth and weight, the S750 stands out as one of Grado’s most focused and technically engaging offerings to date. Audiophiles who appreciate the Grado sound signature and want a more refined, linear presentation will find a lot to love in the Signature S750.
