Sound Quality
The HiFiMAN Edition XS is, above all else, a soundstage headphone. From the moment you press play, the presentation opens up into a vast, holographic space that dwarfs nearly everything else in the sub-$500 category. This is not the subtle, intimate staging of a Sennheiser HD 600 or the moderately wide field of HiFiMAN’s own Sundara — this is a genuinely expansive, room-like experience that makes orchestral recordings breathe and live-concert tracks feel convincingly spacious. Instruments separate with precision across the left-right axis, and there is a real sense of depth layering that many headphones at this price simply cannot reproduce.
Much of this performance comes down to HiFiMAN’s stealth magnet design, which uses specially shaped magnets to reduce acoustic wave interference as sound passes through the driver assembly. Traditional planar magnetic designs rely on bar-shaped magnets that create turbulence in the sound wave, introducing subtle distortion and coloring the output. The stealth magnets on the Edition XS address this directly, and the result is a cleaner, more transparent window into the recording. The improvement is most apparent in the upper midrange and treble, where the Edition XS avoids the thin, grainy character that can plague lesser planar implementations.
Bass response is one of the Edition XS’s strongest suits. Planar magnetic drivers are inherently capable of extending deep into sub-bass territory without the rolloff typical of most dynamic drivers, and the Edition XS takes full advantage of this. The low end reaches down flat to around 20Hz with genuine authority, and sub-bass rumble on electronic tracks and film scores arrives with satisfying physical presence. Critically, the bass is textured and well-controlled rather than bloated — kick drums have a tangible snap, and bass guitar lines maintain individual note definition even in dense mixes. Compared to the Sundara, which can sound slightly lean below 60Hz, the Edition XS fills in the bottom octave more convincingly without ever bleeding into the midrange.
The midrange is smooth and slightly warm, lending vocals and acoustic instruments a natural, lifelike tonality. There is no aggressive upper-midrange shout or sibilance here, which makes the Edition XS remarkably easy to listen to for extended periods. Treble extends well into the upper registers with good air and sparkle, and notably, the Edition XS avoids the elevated treble peak around 8-10kHz that has been a persistent characteristic of many HiFiMAN models over the years. If you found the Sundara or the older Ananda to be occasionally sharp on bright recordings, the Edition XS represents a meaningful step forward in treble refinement.
Imaging is precise without being clinical. Individual instruments and voices are placed with clear spatial definition, though the Edition XS prioritizes a wide, enveloping presentation over laser-sharp pinpoint accuracy. This makes it a superb choice for classical music, jazz, and atmospheric genres where the sense of space is paramount. It also makes the Edition XS a surprisingly excellent gaming headphone — the wide soundstage provides genuine competitive advantage in positional audio, placing footsteps and environmental cues with intuitive clarity. The dynamic range is commendable for a planar at this price, handling both delicate passages and explosive crescendos with composure.
Build & Comfort
This is where the Edition XS narrative gets complicated. HiFiMAN has a long and well-documented history of build quality concerns, and while the Edition XS represents some improvement over older models, it does not fully escape the criticism. The headphone’s structural frame relies heavily on plastic components, and the yoke assemblies in particular feel fragile relative to the $350 asking price. The swivel mechanism works but does not inspire confidence — there is a sense that aggressive handling could lead to stress fractures over time. This is a headphone that rewards careful, deliberate use rather than rough daily carry.
The suspension-style headband is a double-edged design. On the positive side, it distributes the Edition XS’s considerable 405-gram weight across a broader surface area than a traditional padded headband, reducing hot spots and pressure points on the crown. The mesh strap conforms reasonably well to different head shapes. On the negative side, the height adjustment mechanism — which relies on a sliding friction fit rather than a click-lock system — tends to slip over time, requiring occasional readjustment. It is a minor annoyance that becomes more noticeable during long listening sessions when you shift positions.
At 405 grams, the Edition XS is not a lightweight headphone by any standard. It is lighter than the HE-X4 it effectively replaces, but the weight is still noticeable during sessions exceeding two hours. The ear pads are generously sized and use a beveled design that provides good depth for larger ears, and the padding is soft enough to remain comfortable against the skin. Clamp force is moderate — firm enough to maintain a stable fit without creating jaw fatigue. The detachable cable terminates in a standard 3.5mm connector on each cup, which means replacement cables are widely available and affordable. HiFiMAN includes a basic cable in the box that is serviceable but unremarkable.
The overall aesthetic is understated and industrial. The large oval ear cups with their exposed grilles give the Edition XS a distinctly audiophile appearance that will look right at home on a desk setup but would draw odd looks in public — not that you would wear an open-back headphone outside anyway.
Value Proposition
At $350, the HiFiMAN Edition XS occupies an interesting position in HiFiMAN’s own lineup. It sits just above the Sundara at $299 and just below the Ananda at $399, and frankly, it outperforms both in several key areas. The soundstage alone justifies the step up from the Sundara, and the stealth magnet technology gives it a transparency edge over the older Ananda design. For listeners who prioritize spatial presentation and bass extension, the Edition XS is arguably the best value in HiFiMAN’s current catalog.
The 18-ohm impedance and relatively high sensitivity mean the Edition XS can be driven adequately from a phone, tablet, or laptop — though it certainly benefits from a dedicated amplifier. This accessibility broadens its appeal considerably; you do not need to invest in expensive amplification to get excellent results. A simple dongle DAC like the Apple USB-C adapter or a Tempotec Sonata HD Pro will bring out the Edition XS’s full potential without breaking the bank.
Looking beyond HiFiMAN, the Edition XS competes favorably with the Sennheiser HD 660S2 at $499 and the Beyerdynamic DT 1990 Pro at $399. Neither of those headphones can match the Edition XS’s soundstage width, though both offer advantages in build quality and, in the Sennheiser’s case, midrange intimacy. For gaming, classical music, and any genre where spatial presentation is paramount, the Edition XS is difficult to beat at any price under $500.
The core audience for this headphone is the enthusiast who wants genuine high-fidelity sound without the high-fidelity price tag. If build quality is your top priority, look elsewhere. But if you are willing to handle the Edition XS with reasonable care, the sonic rewards are extraordinary for the investment. It is one of the rare headphones that genuinely makes you hear things in familiar recordings that you have never noticed before — and at $350, that is a remarkable achievement.
