Sennheiser IE600 VS Softears Volume S

Youtube Video Summary

$700 buys a compact, 3D-printed metal single-DD that looks mature and fits like a glove. The IE 600 arrives with two cables (3.5mm and 4.4mm) that are thin and comfy but a bit microphonic thanks to stiff, moldable ear hooks. Connectivity is MMCX, yet Sennheiser’s slightly non-standard recess limits third-party cable options. Isolation is a touch below average, but the tiny shells seat past the tragus, stay secure, and even work as a sleeping IEM. The real facepalm is the stock tips—especially the silicone set with collapsing walls. Foam tips are usable (and subtly affect treble), but the easiest fix is Final E-type tips, which keep the incisiveness while curbing sibilance better than Moondrop Spring Tips.

Tonally, think tasteful V-shape: a sub-bass-weighted low end with just enough mid-bass wallop for body, natural and appropriately forward mids, and spicy, well-extended treble. The draw is the technical ride—top-to-bottom texture, punch, and an almost visceral snap. Bass is a standout: deep, delineated rumble that doesn’t smear the mids yet feels physical on everything from EDM to Fleetwood Mac. Treble gives cymbals real weight and timbre (a spot where many sets thin out), while stage is bigger than average with solid imaging—cohesive rather than gimmicky holography. Compared side-by-side, it’s bolder and more contrasty than a warm-neutral Zen Pro, and far more physical than the airy, sterile-leaning Moondrop S8, yet it keeps vocals clean and convincing.

Quibbles exist—awful stock tips, a touch of treble bite depending on fit, and that picky MMCX—but the core experience is special. With a quick tip swap, IE 600 delivers endgame-within-reach performance: exhilarating bass quality, incisive treble, natural mids, comfort for hours, and virtually no deal-breaking caveats. At $700 it’s not cheap, but it competes fearlessly with far pricier IEMs and feels like a set to buy once and be done.

The Softears Volume S at $320 sets a new tonal benchmark for IEMs in its price range. It arrives in solid packaging featuring a zippered carry case (a bit large but functional), protective earpiece pockets that might feel overkill for some, and two excellent sets of ear tips – including Softears' own highly-regarded Ultra Clear tips. Build quality is generally fantastic, highlighted by a resin shell, a comfortable paracord-style cable with a low-profile, user-swappable termination system, and recessed 2-pin connectors. While the aesthetics might feel a bit old-school to some, the fit is comfortable and stable due to its semi-custom shape and longer nozzle, making it secure enough for sleeping. A small screwdriver-adjustable tuning switch offers a secondary, brighter Harmon-like sound signature, though the default tuning is preferred.

The default sound signature is a warm-tilted neutral, delivering exceptional natural timbre and tasteful bass boost. This bass stands out for its exceptional physicality – punchy and impactful without being overbearing – alongside articulate sub-bass that’s easy to follow. Combined with well-defined transients, particularly in the upper-midrange, it creates a satisfyingly rich and dense presentation. While spatial effects and imaging are competent but not standout, the overall tonality and bass quality are remarkably refined. Comparisons show it offers a better tonal balance and bass control than the bassier Dunu DaVinci, significantly more body and richness than the brighter, thinner Moondrop Blessing 3, and trades blows with the Moondrop Dusk – the Volume S providing superior density and mid-bass presence versus the Dusk's more open, spacious presentation.

Ultimately, the Softears Volume S earns a full five-star rating. It might not be the absolute most technically dazzling IEM, but its fantastic tonal balance, unique bass physicality, and overall refinement make it a compelling choice. For $320, it delivers a sound signature that feels just right – rich, satisfying, and universally appealing – challenging more expensive offerings and establishing itself as a top contender in its class.

Youtube Video Summary

The Softears Volume S emerges as a standout vocal specialist under $500, often described as a "mini studio 4“ due to similar frequency graphs. However, it trades some treble detail for superior scaling and a heightened focus on the mid-range, particularly vocals, while adding a touch more mid-bass oomph. This treble reduction allows the music to breathe, creating a more immersive and musical experience that pulls the listener deeper into the sound compared to the Studio 4, without sacrificing a sense of space or leaving the bass and treble feeling inadequate. Though not bass-heavy or treble-head oriented, the low-end provides enough thump and the highs enough air to avoid sounding lean or dark, resulting in a presentation that's slightly less technical and balanced than the Studio 4 but excels in vocal delivery and engagement.

A key feature is the tuning switch which boosts upper mids and treble while lowering the bass, effectively transforming the sound into a cleaner, more technical version of Harman 2019, even surpassing the Studio 4 in detail retrieval in this mode. However, this boosted configuration can sound shouty, lean, and overly clinical for many preferences, lacking the thickness of the stock tuning and scaling less effectively at higher volumes. The stock tuning, preferred for its vocal prowess, truly comes alive with increased volume. The included clear tips are recommended for a slight treble lift and comfort, and the bundled USBC adapter adds a subtle amount of sub-bass rumble, though the low-end remains clean and controlled, reminiscent of leaner sets like the Pilgrim, not providing heavy slam.

While the Studio 4 remains a solid, well-balanced all-rounder, especially on sale around $350, and alternatives like the EM10 (more detailed), Supermix 4 (better value), the Volume S carves its niche with exceptional vocal performance at higher volumes using the stock tuning. Its main drawbacks involve the confusing switch design (requiring opposite positions on each earpiece for the same tuning with no clear indicators) and the pricing debate; using non-branded drivers suggests a more appropriate price point would be $200-$250 rather than $300. Despite these quirks and marketing claims about the passive radiator's role (its actual impact being debatable), the Volume S delivers a great sounding, flexible IEM offering distinct sonic profiles based on volume level and switch position.

Youtube Video Summary

Sennheiser IE600 hits with a confidently V-shaped signature: powerful yet tidy bass that thumps with dynamic-driver slam, a flat, clean lower midrange, and lively upper mids that make vocals and instruments pop. Timbre is notably natural—free from plasticky glare—and the treble pushes plenty of sparkle and micro-nuance without tipping into sibilance or fatigue for most listeners. The result is an energetic yet slightly analytical listen, where details jump out, separation stays intact, and the stage opens up with convincing width and a sense of air. Imaging shows near-pinpoint placement with real depth, contributing to a presentation that feels both exciting and controlled.

In A/Bs, IE600 trades blows with mid-fi favorites: versus Moondrop Variations, the Sennheiser is the more resolving and a touch more natural in timbre (Variations projects a wider stage and leans cleaner/U-shaped). Against DUNU SA6, SA6 offers the safer, more reference-leaning tuning, but IE600 pulls ahead on detail, note definition, and stage size. Compared with Thieaudio Oracle, Oracle stays truer-neutral, yet IE600 flexes stronger technical performance—the kind usually reserved for pricier sets, rivaling classics like Clairvoyance and Monarch Mk1. The catch is treble quantity: those sensitive to extra top-end bite may find it a bit much. Everyone else gets a compact, feather-light shell with outstanding comfort, a richly textured low end, vivid mids, and class-leading detail under $1,000—an easy recommendation if an energetic treble tilt fits the taste.

Youtube Video Summary

The Softears Volume S delivers a distinctly colored sound signature with significant boosts in two key areas: the bass and the upper mid-range. Its bass profile is uniquely elevated up to around 300Hz, resulting in a physical, heavy, yet well-defined low end that impresses with substantial note weight and attack, appealing even to bass enthusiasts. Vocals cut through clearly due to the upper mid-range boost, but this tuning comes with a trade-off: a noticeable sense of hollowness and a narrower soundstage that can feel congested on certain tracks, creating a love-hate relationship with its presentation.

The treble offers a safe, natural, and polite character, providing adequate detail without excessive brightness or roll-off, though it may lack sparkle for some listeners. Technically, the Volume S performs at a level comparable to the Moondrop Blessing 3, excelling particularly in the incisive attack and substantial weight behind each note. When compared to competitors, the Volume S edges out the Tea Pro in bass quality, separation, and natural timbre, though the Tea Pro offers a wider stage. Against the Blessing 3, the Volume S trades openness and cleanliness for a more fun, bass-forward and impactful experience. It also presents a more balanced signature than the brighter, more treble-focused Kiwi Ears Astral.

Ultimately earning an A-minus rating, the Volume S is highly recommended for those seeking exceptional bass quality and a fun, colored tuning. However, it might not suit listeners prioritizing a wide soundstage, a neutral signature, or a bright, sparkly treble with forward micro-details; these listeners are advised to audition first.

Youtube Video Summary

Sennheiser’s IE600 reads like a course correction for a storied brand whose IEMs long suffered a 2–5 kHz dip and blunted energy. Here the midrange is finally set straight—no weird upper-mid recession, just natural, well-placed mids with proper presence. The single dynamic driver is tuned with uncommon discipline: a sub-bass-focused shelf that brings power and tactility without bleed, staying tight and controlled where past models went mushy.

The twist is the treble: an emphasis around 9–10 kHz that can split listeners. For some, that edge will read as sibilant; for others, it’s the rare, airy sparkle that makes cymbals and transients feel alive—call it the “blue cheese” effect. Technical chops are no afterthought either; resolution sits shoulder-to-shoulder with the IE900, trading blows with heavy hitters like Softears Turii, Dunu Luna, and JVC HA-FW10000, while avoiding their tuning quirks.

Measured against its field, the IE600 delivers A+ tone, A+ technical performance, and at $700 earns serious value credentials—enough to make the pricier IE900 feel hard to justify. In the wake of the Sonova acquisition, this feels like redemption: a market-breaking Sennheiser IEM that gets the fundamentals right, then adds just enough treble audacity to be special.

Youtube Video Summary

Softears Volume S follows the 2022 Volume and steps into a fiercely competitive ~$320 bracket with a seriously premium kit: a gorgeous leather case, modular screw-on terminations, both standard and Ultra Clear eartips, IM booties, and tiny screwdrivers for the on-board potentiometer. The stealthy black resin shells with exposed carbon-fiber faceplates feel solid and fit well thanks to slim nozzles; just note there’s no nozzle mesh. The big caveat is the cloth-sheathed stock cable—ergonomically nice but with heavy microphonics. Two tunings are selectable: low-impedance (≈10Ω) and high-impedance (≈31Ω). The low-impedance mode is the keeper; it’s easy to drive yet sensitive to source output impedance, so a dongle under 1Ω is recommended to avoid unintentionally shifting the tonality.

In low-impedance mode the signature is neutral-natural, a flatter, more mid-centric take on “new-meta.” Bass offers quality over quantity: textured, punchy, and responsive without tipping into basshead territory. The mids are the star—clean, warm-tinged lower mids give male vocals body while female vocals sit forward without shout, keeping timbre natural. Treble is smooth, airy, and non-fatiguing, avoiding metallic glare while preserving sparkle. Technical performance is confidently above average for the price: imaging & stage feel wide and well-layered, with good separation and resolution that rewards attentive listening without forcing it.

Positionally, think “Kato upgrade”: smoother treble, better bass texture, and a refinement that many will prefer. Versus spicier rivals like DaVinci, Project Meta, Dusk DSP, or Mega 5 EST, the Volume S sounds more controlled and “correct,” trading some slam and upper-air fireworks for coherence and timbre. It won’t thrill bass lovers, treble heads, or detail chasers seeking a spotlighted presentation; everyone else gets a superb all-rounder that feels benchmark-worthy—the HD600/650 vibe for IEMs. Verdict: you should buy this if a do-it-all, neutral-natural tuning is the goal; just mind your source impedance and consider swapping the cable to kill the microphonics.

Youtube Video Summary

The Softears Volume S delivers a fantastic hybrid sound in its low impedance mode, characterized as a warm neutral tuning with a lush note weight, good bass punch without bloat, and a slight upper-midrange emphasis that makes vocals pop. This signature translates exceptionally well across both music listening and competitive gaming, offering great separation, layering, and phenomenal imaging for precise positional awareness. While engaging and non-fatiguing, gunfire and intense effects in games like Apex Legends can sometimes feel on the verge of shouty or slightly occlusive during chaotic, high-level scenarios, lacking that last bit of air and resolution in the upper mids.

Gaming performance shines across multiple titles. The Volume S provides outstanding depth perception and accurate imaging for Apex Legends slides and light footsteps, excels in Valorant with its separation and verticality, handles the chaos of Call of Duty exceptionally well, and proves to be a top recommendation for Fragpunk due to its loud, precise, and easily trackable footsteps. The smaller resin chassis offers great comfort and ergonomics, especially for those struggling with fit, though it doesn't feel quite as premium as some metal competitors in its price range.

Significant drawbacks include the utterly dismissed high impedance mode tuning, deemed "absolute garbage" and a headache for gaming, and the fragile tuning mechanism itself, prone to easy damage. The included shoelace-style cable is functional with a removable termination but not a favorite, and the unboxing experience, while decent with a pleather case, extra termination, and two sets of silicone tips, is fairly typical for the price. Ultimately, the Softears Volume S stands as a killer all-around IEM when locked into its excellent low impedance mode, highly recommended for its crossover appeal despite the useless tuning switch and build quibbles.

Youtube Video Summary

Softears Vol S leans into a mid-bass emphasis that is uncommon among recent hybrids, pairing boosted sub- and mid-bass with full-bodied, lower-mid vocals. The result is a naturally thick, lush midrange that favors genres needing body over sparkle, and the relaxed treble beyond ear-gain lets volume changes scale bass and treble together. At higher listening levels the set can hit hard and verge on bass fatigue, but within moderate levels it fills a clear gap left by leaner U-shaped tunings.

Trade-offs are plain: the upper-treble sits back, so stage is smaller and overall resolution is lower versus airier peers; some upper-end information gets masked by the bass weight. The impedance switch adds a bit of brightness but also trims the pleasing volume scaling, bringing limited benefit. Not a $300 class leader, yet a well-tuned alternative for listeners who prioritize natural, weighty mids over maximum air and sparkle.

Youtube Video Summary

The Softears Volume S offers a dramatic transformation through its impedance switch, requiring a tiny screwdriver to toggle between low (9.8 ohm) and high (31.2 ohm) modes. The low impedance mode is described as painfully clinical, bland, and annoyingly sterile across all tested amplifiers. It’s reminiscent of the disliked original Volume model, lacking any enjoyable tuning despite EQ attempts. This mode only suits listeners craving absolute neutrality, offering little musical engagement.

Switching to the high impedance mode completely revolutionizes the experience. It becomes relaxed, unoffensive, and remarkably smooth, with notes possessing a lingering, church-like resonance that adds emotional depth. This mode presents music with a spacious, uplifting quality and a subtle chest-felt pressure during resonant passages. However, it demands quality amplification to shine and benefits from tip-rolling; the included sticky liquid silicone tips enhance the signature, though alternatives like Azla SednaEarfit can tweak the response. Comfort and build are excellent, though the fabric cable exhibits some microphonics.

Priced around $300, the Volume S earns a cautious recommendation primarily for its stellar high-impedance performance. It requires tinkering with tips and sources to reach its potential and faces stiff competition in its price bracket. While not an outright class leader, it’s a significant upgrade over the original Volume. The package includes a luxurious case, multiple tips, and a branded USB-C adapter, reflecting Softears' typical attention to detail. Just keep it locked in high-impedance mode.
