Kefine Klean VS Truthear Pure

Youtube Video Summary

$50 single dynamic driver with a surprisingly premium feel: a compact, solid shell, gold nozzle, flat 2-pin connectors, and a neat white cable with a chin slider that actually stays put. The small included case is simple but well-built, and there’s a second nozzle to tweak the sound plus basic tips—nothing flashy, just clean and functional. Overall presentation looks and feels pricier than the tag suggests.

Tonally, this is a flat-neutral leaning set with impactful bass, clean mids, and extension that’s acceptable for the bracket; minor caveats include a desire for a touch more sub-bass and elevated energy around 4–5 kHz and 8 kHz. Detail and air are solid for the money, imaging is confident, and the stage feels pleasantly open, though upper-treble can edge into splashy territory. It’s not the budget slayer hyped elsewhere, but it’s a very good listen that suits a wide audience, especially those who prefer a more laid-back tuning.

Against peers: preferred over the brand’s planar Klar; the livelier Delci brings more bass sparkle and “fun,” while Klean reads calmer and more mid-focused. The Awaken Dawn MS offers bigger bass and air; Klean counters with better build and accessories—great as a gift set. Versus value champs like Waivering Abyss, KZ EDC Pro, or sub-$10 curios, Klean sounds better but the gap narrows when price is king; step-ups like AFUL Explorer, Moondrop Aria, or Moondrop May can out-resolve or reshape the profile if spending more. A light EQ nudge (more sub-bass, slightly tamed mid-treble) dials it in. Final take: full recommendation on merit and build, with rough scores around Bass 8, Mids 7.5, and an overall solid ~7.7/10 for value.

Youtube Video Summary

The Truthear Pure offers a neutral, JM1-style target tuning aimed at a studio-reference sound, achieving this goal competently for its price point. However, its build quality and accessories feel disappointing and recycled from older models like the Hexa. The shell contouring is rigid and unimpressive, while the tips and case lack innovation. The cable is a slight improvement over the Hexa's – supple but lacking clear right/left indicators – making the overall package just okay, not exciting.

Sonically, the Pure presents a linear bass rise and a generally neutral presentation, differing from the Hexa by offering a bit more warmth but less sparkle and magical mid-range presence. While it fixes the Hexa's "pillowy bass," it doesn't fully surpass it, lacking the Hexa's legendary status. Comparisons reveal it's very similar to the Audio Sense DT200 in tonality, though slightly preferred. It falls short against competitors like the Kiwi Ears Quartet (better bass/mids), Ziigaat Lush (better technicalities), Softears Volume S (more natural curve), or planar options around its price. Crucially, the fit is problematic, often requiring expensive aftermarket tips like the Baroque to work well, which feels impractical for a $90 IEM.

Ultimately, the Pure is a solid but middling release, earning a B rating. It suits those specifically seeking an affordable JM1-style neutral signature or dedicated Truthear fans. For most listeners, however, better alternatives exist: the Hexa remains preferable within Truthear's lineup for its magic, the Nova offers more fun, or competitors like the Aful Explorer (bass-focused), TANGZU Fudu (value planar), or slightly pricier Volume S provide more engaging or technically proficient experiences. It's not a strong general recommendation.

Youtube Video Summary

Kefine Klean keeps the K-jokes going, but the hardware is serious: a DLC diaphragm single-dynamic in a full metal shell with a bit of girth yet a surprisingly comfy fit. The knurled nozzle is chunky—getting tips on can be a chore—but the payoff is real because the screw-on caps flip the tuning. The stock silver caps read safe and kinda boring; swap to the black caps and the Klean snaps into focus: more engaging, more direct, cleaner pass-through. Call it forward, a touch aggressive, with punchy impact and lively presence.

Tip rolling moves the needle a lot. With Dunu SS it tightens and brightens; foam “render” tips add low-end bite and smooth things; wide-bore silicone acts like a mini waveguide, opening space before the sound hits the ear. Treble can push up—spicy on some tracks—so pairing and tips matter, and funnily enough it responds to tubes with a sweeter top. Build is clean, 2-pin flush, a smooth and perfectly fine cable for the price, and overall execution that feels better than budget-bin.

Discovered at $50 retail, the Klean plays in Tin T2 territory but with more “sit up and watch the fight” energy. There are reports out there about clogged filters after weeks, but judged on sound/price today, this is a no-brainer. With the black caps and the right tips, it performs like a $100–$120 set—basically worth twice as much. For a budget brawler that doesn’t annoy, hits hard, and stays entertaining, buy these and be happy.

Youtube Video Summary

Truthear Pure brings a warm, bass-impactful presentation from its 1DD+3BA setup, but the rest feels like it’s under a blanket. There’s a noticeable 2 kHz hump, then the upper range ducks hard past ~8 kHz, leaving the sound veiled—like three comforters thrown over the music. Great for bass-centric tracks (think Arcane S2 remixes), yet dull and somehow fatiguing at the same time. The shells look cool—semi-transparent with a heatsink-style back—and the stock cable is soft and supple but fixed 3.5 mm. Accessories are classic Truthear: small leather pouch, tip array, and a waifu postcard. Listed around $89 (feels more like $50 value).

The real curveball is the imaging and stage. On 3D test tracks that should sweep smoothly around the head, motion skews and snaps—front/back depth behaves weird and timing feels off. It’s the kind of tuning (or implementation) that begs for EQ just to “open it up”. For listeners who want warmth + bass and the bunny-girl aesthetic, this will scratch the itch. For a cleaner, properly integrated 1DD+3BA experience, alternatives like Defiant make more sense, especially at a similar price. Net: an acceptable set for bass enjoyment, but with odd staging and a rolled-off, veiled top end that keeps it off the must-buy list.

Youtube Video Summary

Truthear Pure arrives as a $90 1DD+3BA hybrid with a solid accessory set: postcard, soft pouch, six pairs of silicone tips plus foam. The non-modular cable is notably soft, tangle-free, low in microphonics, and the chin slider actually stays put. Shells are semi-transparent 3D-printed resin with a grooved faceplate, a vent, and a nozzle lip that keeps tips secure; there’s a recessed 2-pin connector. Size is only slightly larger than Hexa, but comfort is similarly excellent—low-profile, secure, and easy for long sessions.

Sonically, Pure shifts firmly into warm territory. Bass is abundant with strong slam, yet its slower decay and “glide” into the lower mids introduce a thick, relaxed presentation that can cloud mid-range clarity and leave vocals a touch hazy; the upper-mids sit a bit too laid-back for the bass level. Treble is safe, smooth, and non-fatiguing rather than airy. Technicals are middling for the class—imaging decent, detail behind more incisive sets. Versus Hexa, Pure adds bass and impact but loses the Hexa’s clean, neutral midrange; compared with Moondrop Aria 2, it’s the “too warm” side of warm-tuned. Best suited for listeners who want a cozy, laid-back signature; not ideal for clarity seekers unless EQ is used to trim the low-mids/bass. Final verdict: 3/5 stars—comfortable build and enjoyable smoothness, but the warmth dominates the balance.

Youtube Video Summary

Kefine Klean hits the sweet spot for an entry-level daily driver by being both affordable and flexible. Out of the box it delivers a warm, easy listen with decent technical chops, then flips character with the included black nozzle: upper-mids get more bite, the overall profile cleans up, and the vibe shifts closer to a crisp, energetic tuning reminiscent of sets like the EW200. That two-for-one versatility makes it a smart pick for anyone torn between a cozy, relaxed tonality and a brighter, snappier presentation.

Build and accessories are solid for the price, and the performance is consistently competent rather than showy—good resolution for the bracket, no egregious peaks, and a tuning that’s easy to live with. The real hook is how the Klean can cover multiple moods without extra spend: leave the stock setup for smooth, laid-back sessions, or pop in the black nozzle when more presence and clarity are wanted. As a starter set that can grow with different preferences, it’s an easy recommendation.

Youtube Video Summary

Truthear Pure lands as the so-called Hexa successor, but the tuning pivots hard: it’s warmer, darker, and even more laid-back. Male vocals pop with weight, extension, and a lush low-end foundation. At mid-to-low volumes it can come off bloated and a little low-res up top, with dulled upper-mid/treble detail; push it to around 75 dB+ and it scales nicely, opening the stage, adding clarity, and staying non-fatiguing thanks to the tamer upper mids.

Genre pairing leans into hip-hop, rap, R&B, jazz, and rock/metal: there’s satisfying mid-bass impact and sub-bass rumble, with restrained upper mids keeping sibilance and shout in check on hotter recordings. Tipwise, avoid bass-boosters like Final E, Divinus Venus, and even the stock silicones. Go with Softears Ultra Clear or other clear, open-bore tips to nudge in more treble air while keeping the smoothness.

On raw technicals, Pure isn’t class-leading for its bracket—less detail and separation than the older Hexa despite sharing drivers, because the warmer/darker tilt trims perceived clarity. Buy it for the tuning and volume scaling. It plays like a more vocal-centric spin on the AFUL Explorer (darker, immersive, vocals pop more, a bit less sub-bass-centric). Chasing value or technical bite? Sets like EW300 (on sale) or Moondrop Aria 2 Red, and of course Hexa, will feel cleaner and crisper. Bottom line: a side-grade with its own niche—great for listeners who prefer a warm, smooth presentation and aren’t shy about turning the volume up.

$49 single dynamic done right: Kefine’s Klean keeps it simple with a solid unboxing and surprisingly premium build for the price. The CNC aluminum shells feel upscale yet stay lightweight and comfortable, especially for smaller ears, though seal and stability could be tighter. The stock cable stands out—supple, well-textured, and visually clean—even if it’s not modular or balanced at this budget. Tip-rolling helps due to the slightly stubby nozzle; options like TRI Clarion or M-type S&S open things up. Two nozzles sweeten the deal: the silver mesh stock option captures the set’s “clean” identity, while the gold nozzle adds a bit more upper-mid energy and can mask the upper-treble bite.

Sonically it’s a modern V-shape that leans warm: a tasteful bass shelf with satisfying tactility, linear mids that flatter vocals, and an overall smooth, versatile presentation that just works across genres. The caveat is an 8 kHz emphasis that can bring edginess or a touch of low-res sheen on hotter mixes. Against the field, TRN Kunch brings better accessories and flexibility but sounds thinner and sharper; SimGOT EW200 and QKZ x HBB Q5 Pro (Q5 Pro) deliver higher technicals and brightness at the cost of fatigue; KZ Zenith is tonally similar (including that 8k peak) but crisper; and Kefine’s own Deli remains the overall step-up with cleaner treble and mids—at a higher price. Verdict: a clean-tuned, easy-listening budget pick with broad appeal, scoring 6.29/10 with 7/10 enjoyment and earning the Bam Obi Panda Approved nod.

Youtube Video Summary

$50 buys a surprisingly solid package: an all-metal shell with a thin but sturdy hard case, a well-behaved two-wire cable, and two tuning nozzles (silver stock, black bright). The build is on the heavier side with a slightly wider nozzle, yet comfort proves better than expected and drivability is easy (32 Ω / 107 dB). Aesthetics lean understated—clean lines, nothing flashy—so don’t expect compliments, just a practical carry and clear R/L markings. Overall accessories and finish fit the thrifty brief, and the knurled nozzles make swaps quick.

Sonically it’s a v-shaped tuning done right: sub-bass rumble and mid-bass punch add texture without veering into basshead territory; lower mids carry a touch of warmth that flatters male vocals while keeping instruments separated; female vocals stay natural. With the silver nozzle, treble strikes a neat balance—energetic when needed, relaxed when not—rarely fatiguing. Swap to the black nozzle and the top end brightens noticeably, pushing harmonics and female vocals forward for a more thrilling but less natural tilt. Technical chops are confident for the price: good dynamics, clean separation on messy live cuts, and a pleasantly wide stage with stable imaging. Against peers, the Klean feels brighter than Tripowin Vivace, slightly more technical than SIMGOT EW200, trades blows with INAWAKEN Dawn (Dawn = tighter sub-bass & mids; Klean = more sparkle), sits brighter than Kefine Delling, and gives a “diet” taste of EW300/EA500 LM treble flavors via its filters.

The verdict: a recommendation for listeners who want a detailed, lively v-shape with real tuning flexibility. It’s worth the ask and competes well, even if neither filter setting is a show-stopper. Not ideal for neutral seekers, full-on bassheads, or those craving a warm, laid-back top end (try Delling or similar). Excellent as an upgrade from Zero:2 for more resolution/treble detail, and a smart way for newcomers to test treble tolerance—silver for natural sparkle, black for extra bite. Deals around $45 sweeten the proposition in an already crowded budget bracket.

Youtube Video Summary

Kefine Klean hits the budget-gaming brief with a warm-neutral / Harman-leaning single dynamic that pushes crisp footstep cues, strong depth perception, and convincing vertical imaging. In calmer scenarios and when approaching buildings, positional info locks in—footsteps above/below and crosshair pulls to distant gunfire feel precise. Compared head-to-head, it delivers roughly 90% of the performance of the pricier Kefine Delci AE, with the main gap being separation and layering during chaotic exchanges where the AE keeps effects more dissipated and easier to parse.

Across titles, the Klean grades out around a B to B- on the WallHack-certified list: in Valorant, it trades blows with the AE—slightly more elevated cues for footsteps/gunfire, just not quite as clean; in Call of Duty it remains competitive with good imaging and distance reads but again cedes a bit of layering to the AE; in Apex Legends, it stays very usable yet the AE’s extra clarity under third-party chaos proves advantageous. As a sub-$100 pick, Klean earns a strong recommendation for competitive play—grab it if the budget is tight or if Valorant is home base, and consider the AE if maximum cleanliness in crowded fights is the priority. The 7Hz G1 trails here, especially in Apex, where cue overload turns messy fast.

Youtube Video Summary

The Truthear Pure keeps the $90 hybrid recipe of the Hexa (3BA+1DD) and most of its shell geometry, but tweaks details: a slightly smaller nozzle eases fit for those who struggled with Hexa, while a thicker body changes how it sits against the antitragus. Accessories are sensible—the pocketable soft pouch and three styles of ear tips help dial in seal and stability—though the bold logo and faint channel markings won’t win style awards. Overall comfort is compact and easy, with fit security largely dependent on tip choice rather than ear-conforming contours.

Sonically this is a shift from Hexa’s laser-neutral baseline to a warm-neutral flavor: ~1–2 dB more energy from 1 kHz down adds body and density, while slightly pulled-back upper mids/treble relax the presentation. Stage size and separation aren’t the selling points, yet the treble execution is impressively clean and controlled for the price, avoiding the congestion feared from early listens. Bass remains not the star, but attack is snappier and kick definition more satisfying than on Hexa, making drums feel better outlined without abandoning neutrality.

Think HD600 vs HD650: Hexa reads brighter, airier, and a touch more “technical,” while Pure is fuller, warmer, and more relaxed—arguably the more mature tonality. For contrast seekers, the Jazir/Z Reviews Defiant hits harder with a lively V-shape; to split the difference with extra low-end and micro-contrast, the AFUL Explorer fits. As a sub-$100 choice, Pure lands as a five-star set: not a technical monster, but a beautifully tuned, dense take on neutral that stands shoulder-to-shoulder with Hexa rather than replacing it—pick Hexa for openness, Pure for tone and treble refinement.

Youtube Video Summary

Truthear Pure follows the beloved Hexa with a smarter twist on neutrality: a hybrid 1DD+3BA at $90 that keeps the sturdy 3D-printed shell, slightly chunkier but similarly comfortable. The package is generous—three pairs of “thick” tips, three “thin,” plus foams—along with a much softer, less tangle-prone cable (still a fixed termination) and a soft leather pouch that’s actually pocket-friendly. Build, fit, and accessories punch above price, making this feel more premium than the tag suggests.

Sonically, Pure takes Hexa’s neutral core and downtilts it: a touch more lower-mid energy for weight and body, with the Hexa’s brighter colorations eased back. The result is a warm-neutral, enveloping, and non-fatiguing presentation—vocals and instruments gain richness without mud, and timbre/decay stay natural rather than dark or blunted. Think of the duo like HD600 vs HD650 for IEMs: pick Hexa for cleaner/brighter clarity, pick Pure for fuller, relaxed musicality. Choose Pure if a superbly executed warm-neutral tuning, long-session comfort, and broad genre versatility are priorities (great as a first “do-it-all” IEM). Skip it if a crisper, more analytical, or treble-forward edge is needed—the Pure presents detail naturally rather than pushing it. Either way, Pure carves meaningful space beside Hexa: neither redundant nor straying too far from true neutral, just the right amount of warmth done right. (Also, a white Pure would be fun—name kinda begs for it.)
