Kefine Delci VS Letshuoer S08

Youtube Video Summary

The Letshuoer S08 hits with a present, to-the-point delivery: tight, quick, and more “first-row” than lounge seat. Staging isn’t expansive, but the focus and planar speed make music feel energized without turning sharp. Transients snap, treble has some bite yet stays civil, and the overall tuning gives that dopamine kick missing from sleepier sets—engaging, not fatiguing.

Build and kit are surprisingly premium for the bracket: a comfy, small ovoid shell; a springy 4-wire modular cable with both 3.5 and 4.4 plugs; a screw-top, rubber-lined case; and a rotating tip wheel with “balanced” and “vocal” options. Connection tolerances feel tidy with the flush mount, and the silver finish looks cleaner than the stealthy black.

The kicker is the spec and price: a 13 mm planar driver at about $99 makes this a value play with real bite. Judged on price-to-performance, comfort, and accessories, S08 scores a solid 9/10—not a summit killer, but an easy recommendation for anyone wanting a lively, fast planar that simply sounds fun. Letshuoer keeps the streak alive; more of this, please.

Youtube Video Summary

Letshuoer’s S08 marks the brand’s anniversary with a thoughtful package: a supple modular cable (3.5 mm + 4.4 mm with a sturdy knurled lock), six pairs of tips (the wide-bore set trims bass if needed), and a pocketable hockey-puck case. The shells are CNC-milled aluminum—light, durable, and shaped to fit a wide range of ears with notably smaller nozzles than many planars. Spec-wise, the new 13 mm double-voice-coil planar is easy to drive at 26 Ω/105 dB, playing happily off laptops, phones, or DAPs. Comfort is a highlight: no hotspots, stable fit, and a resounding pass on the “tiny-ears test.”

Sonically, the S08 delivers a warm-tilted planar done right: sub-bass and mid-bass have satisfying weight and slam without muddying the midrange. Vocals and instruments remain clean and tonally correct, with upper-mids/treble kept relaxed yet still detailed thanks to planar speed—crisp cymbals and percussion texture without sting. Technicalities impress: strong microdetail and separation, accurate imaging, and an average-wide soundstage that places players precisely on well-mastered tracks. Crucially, the tuning avoids the “planar trap” of turning up the volume into fatigue; it stays smooth, musical, and non-fatiguing, and scales well with EQ if a bass-cannon mood strikes.

Against peers, it reads like a refined Hidizs MP145—even more relaxed up top, better accessories, a smaller shell, and roughly $60 less—while the 7Hz Timeless AE feels overpriced by comparison. The verdict is emphatic: a “you should buy this” rating. As a first IEM around $100 or a fresh flavor for seasoned planar collectors, S08 is a crowd-pleaser: comfortable, easy to drive, non-fatiguing, and musically addictive—an anniversary release with the chops to become a future benchmark.

Youtube Video Summary

Letshuoer S08 comes in a small but chunky shell that’s easy to seat and stays comfortable thanks to a slim nozzle and secure fit. The accessory pack overdelivers: a supple, screw-lock cable with flat 2-pin connectors and an included 4.4 mm plug, plus a simple but protective case shared with pricier Letshuoer sets. Build and ergonomics are rock-solid at the ~$100 mark.

Tonally, S08 leans bass-light with a touch of upper-mid restraint, countered by clean air and above-class technicalities. The graph looks friendly in the mids, but sub-bass could use more weight—which can thin out guitar body and blunt some cymbal impact. Still, the set sounds coherent, with nice extension up top and a presentation that’s easy to live with; a sprinkle of EQ on the low end and a nudge to the upper mids tightens everything up and pushes it toward “great.”

Versus peers, it’s preferred over the Letshuoer S12 thanks to a more relaxed treble; it also beats Truthear Hexa on bass presence and technical ability (fit quirks on Hexa don’t help). AFUL Explorer offers better sub-bass and comfort if spending a bit more, while Dunu Talos trades blows with a brighter tilt and higher price. NiceHCK F1 Pro is hard to recommend due to its 4–6 kHz glare, and the Simgot Singolo brings punchier upper mids and bass but slightly less sparkle/detail. Net take: a good-value planar at $100 (closer to great nearer $80), with minor flaws and clear upside with EQ—an easy recommend for listeners prioritizing balance, air, and comfort over sheer bass quantity.

Youtube Video Summary

The Kefine Delci is a compact 10 mm single dynamic driver IEM with surprisingly premium build for the roughly $59 asking price, using an aluminum alloy shell that feels sturdy yet stays very lightweight in the ear. The small, ergonomic shape fits like a glove, enabling long listening sessions or even napping without discomfort, while passive isolation with the right tips reaches above average compared to many sets at and above this price.

Its tuning is clearly sub bass focused, delivering deep, visceral rumble with excellent extension and control, while the mid bass sits at a tasteful level that keeps things punchy without bleeding into the mids, only really missing a bit of extra texture and slam. The midrange offers a rich, clear and balanced vocal presentation for both male and female singers, and the upper mids plus lower treble bring elevated clarity and detail without turning shouty, though some drum heavy tracks can push the lower treble a hair hot unless tamed with the included narrow bore tips.

Where the Delci really impresses is in technical performance: detail retrieval and micro detail are outstanding for the price, Imaging accuracy is precise, and the soundstage is noticeably wider than average for an IEM, especially when given a bit more amplification. Combined with engaging dynamics, strong sub bass foundation and clean, balanced treble, it ends up feeling like an obvious upgrade over popular bright neutral sets such as the Dunu Titan S and a serious competitor to higher priced options, earning a place as a go to recommendation in the sub $60 bracket.

Youtube Video Summary

Kefine Delci is a single 10 mm dynamic driver set that comes in at around 59 to 75 dollars and feels very solid for a budget in ear monitor. The all aluminum alloy shells are light yet robust, the gunmetal finish looks sharp, and the compact shape offers excellent fit and comfort for a wide range of ears. The stock two pin cable with 3.5 millimeter plug feels a little plasticky to the touch but is surprisingly manageable in daily use, with minimal tangling and a look that pairs well with the shells, so overall the build quality and accessories are easy to be happy with at this price.

Sonically Delci takes a more neutral warm approach than the usual V shaped budget tuning, sitting closer to a natural target while still giving plenty of fun in the low end. Bass has a lot of quantity and can occasionally sound a little unbalanced or thick, and there is some bleed into the lower mids, but the driver delivers impressive bass dynamics for the price with a satisfying sense of punch and air movement. The lower mids carry noticeable warmth and note weight that gives male vocals and instruments heft but can make that region sound slightly less natural at times, whereas the upper mids are where Delci really shines, offering a smooth, natural vocal and instrument presentation that stands out among many sub 100 dollar sets.

The same smooth and controlled character continues into the treble, where cymbal hits have enough energy and texture without becoming harsh, and hi hats carry a gentle sizzle while still revealing detail, so overall the top end feels both safe and engaging. Technical performance is about average for the class, with soundstage that is roughly typical in width for an in ear, decent depth and layering, and detail retrieval that hangs with other solid budget models like CVJ Freedom, Tangzu Fudu, Betti OD100 or Mars T5s, though still a step behind sets such as Simgot EA500 LM and Moondrop Aria 2. What helps Delci push toward the top of its price bracket is how well the tuning of the upper mids and treble is executed, making it a very strong and easy recommendation for listeners who enjoy a neutral warm presentation, do not mind a slightly thick low midrange, and want a great looking, well built, nicely accessorised daily driver in this segment.

Youtube Video Summary

Letshuoer S08 enters the sub-$100 planar crowd with standout build and thoughtful accessories. The compact metal shell looks clean and distinctive, pairing with a soft, well-behaved cable that includes swappable 3.5 mm and 4.4 mm terminations. The angled 2-pin plugs aid stability, the chin slider actually stays put, and the pre-formed ear hooks help the fit. Size is a solid medium; the body tucks in securely, though the front end is a bit bulky and sits slightly forward.

Tonally, S08 favors a warmer, bassier, more laid-back presentation. Treble shows decent extension but stays restrained through the upper-mids/lower-treble, yielding a thicker note weight with less contrast and delineation than brighter planars. Vocals come across more natural than the Tin HiFi counterpart, and high-frequency percussion (hi-hats, brushes, cymbals) sounds realistic and metallic rather than splashy. The weak spot is the low end: bass can turn poofy and a bit smeary, especially on dense mixes, and there can be a touch of sibillance at times.

Overall, S08 shapes up as the better pick versus the Tin HiFi DUDU/Duo on both build and tuning execution, but it’s not a runaway. For listeners wanting a warm, bass-tilted planar around $100, it’s a respectable choice. Verdict: 3/5 stars. If stronger, cleaner bass is the priority (and planar isn’t required), consider an alternative like the AFUL Explorer; otherwise, S08 makes the more compelling case between these two.

Youtube Video Summary

Letshuoer S08 shows up as an easy recommendation for mixed gaming, balancing clarity and comfort with a tuning that’s smooth, a touch warm, and pleasantly velvety. Footstep reads and positional cues are confident across titles, and in Valorant it trades punches with the Dunu Titan S2 at the front of its bracket. More importantly, it tames gunshot harshness—if transients feel hot on sets like the Truthear x Crinacle Zero, S08 makes firefights less fatiguing without smearing detail. It’s a true do-it-all pick that plays well in Apex, Fortnite, and CoD, and it’s notably better than Letshuoer S12 for these uses.

For pure competitive edge, the Wall Hack Certified ranking keeps S08 around the same tier as the Truthear Zero rather than pushing it above—Zero still holds its own on raw performance. But S08’s safer, smoother tuning makes overall sessions more enjoyable and easier on the ears, especially during chaotic gunplay. If the priority is strong imaging and separation with a more relaxed top end, S08 is the favorite of its row and a confident, versatile choice that fits both gaming and casual music listening.
