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.

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.

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.

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.

The ZiiGaat Luna delivers a smooth, full, and slightly warm sound with exceptional airiness, creating a lush and laid-back listening experience. Vocals are presented in a balanced yet warmer, thicker tonality, pulling back slightly in the mix compared to vocal-centric sets like the Arcanis. This tuning emphasizes micro-nuances in the treble, offering well-extended symbol crashes and a refined, non-fatiguing character. Tonally, it sits as a more technical evolution of the discontinued P1 Max and a warmer, more affordable alternative to the elusive Seven Acoustics Supernova or Dunu SA6 series, delivering a similar smoothness and air at roughly $200 less.

Technically, the Luna performs competitively around the Arcanus level, featuring good resolution, layering, and solid bass texture, though it isn't a sheer technical monster. Its unique, musical tonality more than justifies its $350-$379 price. The bass, powered by Sonion drivers, provides quick separation and snappy response with enough warmth for a comfy, nostalgic feel, though it lacks the deep sub-bass rumble and intense slam of dedicated bass sets like the Ziigaat Cincotres or Estrella. This makes the Luna ideal for rock, indie, and metal genres, where its firm mid-bass, full-bodied yet quick decay, pulled-back vocals (preventing shoutiness), and airy treble excel. It scales well at medium volumes (around 75-80 dB), working as an all-rounder but truly shining with bands.

Compared to its sibling, the Odyssey, the Luna is smoother, more laid-back, and airier versus the Odyssey's sharper transients and greater energy. Against the Xenns Top Pro, the Luna offers a warmer, fuller, airier sound but yields in ultimate clarity, vocal forwardness, and transient sharpness. The Kiwi Ears Astral provides a more vibrant, sub-bass focused, and dynamic all-rounder at a lower price, but the Luna counters with superior smoothness, refinement, and a more unique, immersive signature. While vocal-focused sets like the Studio 4 or Volume S offer greater vocal clarity and power, the Luna provides slightly better overall detail retrieval and its distinctive warm, airy musicality. In conclusion, the Luna stands out as a highly competitive set with a unique tuning not commonly found near its price, backed by a quality interchangeable cable, making it a compelling recommendation for those seeking its specific refined, lush, and airy character.

The Ziigaat Luna arrives as a $379 all-balance armature IEM, impressing right out of the box with its premium accessories. You get a large, sturdy zipper case (though not pocket-friendly), three pairs of narrow bore silicone tips, a set of clear silicone tips, foam tips, and a standout modular cable with both 3.5mm and 4.4mm terminations. The cable itself is praised for being tangle-free, flexible, and microphonic-free, featuring a metal y-split and solid modular connections. The Luna sports a resin build with attractive faceplates and an average size shell, offering a comfortable fit familiar to other Ziigaat models, though some might experience pressure using narrow bore tips for a deep fit.

Sonically, the Luna delivers a smooth, slightly warm, and airy signature that's notably non-fatiguing. The bass, while lacking the physical slam of a dynamic driver, is one of the better BA implementations, offering satisfying mid-bass thump, definition, and gentle rumble. The mid-range has a touch of warmth adding body and naturalness, with proper note weight and slightly relaxed yet clear vocals that work well across rock, metal, hip-hop, and more. The treble is sparkly and airy with good micro-detail, thanks to an upper air boost, though this could be noticeable for sensitive listeners. Technically, it lands around 80% between the TruthEar Nova and Dunu SA6 Ultra, with excellent imaging precision, above-average soundstage, and nice layering.

Comparisons reveal the Luna shares a similar tonality to the discontinued, more expensive Dunu SA6 Ultra, making it a great alternative. It bests other Ziigaat models like the Arcanis and Odyssey in overall balance, detail, and air, though the Odyssey offers more bass physicality. Against strong competitors like the Kiwi Ears Astral or Xenns Mangird Top Pro, the Luna holds its own with a warmer, fuller, and more relaxing presentation, even if it concedes in ultimate refinement or bass impact. It earns a solid 4 out of 5 stars for its unique, competitive tuning and fantastic value, highly recommended for those seeking a detailed yet relaxing all-rounder with smooth vocals and airy sparkle. However, bassheads, those sensitive to upper treble, or seekers of neutral/reference tuning should look elsewhere.

The ZiiGaat Luna impresses immediately with its solid build quality, featuring a comfortable metal nozzle shell and a unique wing design for a secure fit. While the shell doesn't reinvent ZiiGaat's typical mold, the accessories show significant improvement, including a nice selection of tips, a practical case, and a simple but effective cable with swappable terminations (including 4.4mm). This attention to the unboxing experience, especially at its $379 price point, demonstrates ZiiGaat listened to community feedback.

Sonically, the Luna delivers a bold, clean, and tactile V-shaped signature with exceptional micro-detail and a fantastic overall frequency response. It stands out as a supremely capable all-rounder, offering a touch of hi-fi quality. Comparisons reveal it surpasses other ZiiGaat models like the specialist Arcanis, the neutral Lush, and provides a clear upgrade path over the Odyssey. While the Mangird Top Pro offers thick, majestic bass, the Luna boasts better clarity and detail and is deemed a more versatile choice. It also compares favorably to benchmarks like the Aful Performer 7, offering better treble and a cleaner presentation, and edges out the 7th Acoustics Supernova with a slightly more agreeable tuning.

Ultimately, the Luna hits a remarkable sweet spot. It combines a balanced sound with great technicalities, improved accessories, and a tonality that avoids harshness while retaining excitement. For its price bracket, it represents a fantastic value and emerges as a strong contender for the benchmark all-rounder in the $300-$400 range, offering a taste of high-end performance without the ludicrous cost. It’s a clear sign of ZiiGaat refining their approach based on user input, resulting in one of their finest IEMs to date.
