Letshuoer S08 VS Kinera Celest IgniteX Beast

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 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.

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.

Celest Ignite X Beast pairs a striking 3D printed faceplate with an ear hugging shell that uses a wing to lock in place, giving a tighter fit and stronger passive isolation than the simpler Wyvern style shells from the brand. The body of the shell is a bit larger, so it fills more of the ear, but for those who tolerate the wing the result is a secure, comfortable wear with an immersive seal that suits louder environments. The package is modest overall, yet the inclusion of the familiar 07 eartips is a nice touch, offering a genuinely good tip option even if the basic black cable feels rather generic for what Celest can usually offer.

On the tuning side Ignite X Beast uses a one dynamic plus one balanced armature setup aimed at a tuning concept rather than another safe Harman style curve, with elevated sub bass and mid bass defining a full, fun low end. The bass reaches deep with roughly 8 to 9 dB of lift and flows smoothly into the lower mids, giving electronic and energetic tracks plenty of weight while still feeling reasonably controlled and supportive of the treble. Upper mids and presence are shaped more unconventionally, with an early rise and a noticeable dip through the presence region that pulls vocals back, so voices and acoustic instruments sit behind the strong bass and the later treble emphasis.

The treble is tuned for engagement rather than strict neutrality, combining an early 2 kHz lift with a later boost around 10 kHz, which can sound slightly bright or thin to some but matches the overall V shaped profile and gives synths and effects extra sparkle. This focus on bass and treble makes Ignite X Beast a better match for electronic music and other non vocal material than for traditional pop or rock where natural vocals matter more, and overall it feels like a niche but coherent idea rather than a universal daily driver. Within the Celest lineup it comes across as an interesting experiment in hybrid tuning with solid but not class leading technicalities, with the main appeal being a different and fun signature instead of the strongest value choice in its price bracket.
