Aful Performer 8 VS Letshuoer S12 Ultra

Youtube Video Summary

LETSHUOER S12 Ultra wraps up the S12 line with a 14.8 mm planar driver and a familiar metal shell in gunmetal or mocha. The housing is vented, comfy for long sessions, and solidly built with a flat 2-pin interface that grips tips well. The stock package is practical: a soft case, a fair tip spread, a braided cable with swappable 4.4 mm termination, and even a plug-and-play USB-C DAC that performs capably for on-the-go use.

Sonically, this set aims for a mild V-shape with tasteful tweaks that elevate it over prior S12 iterations. There’s a touch more sub-bass than the S12 Pro and a smoother 10 kHz zone, reducing fatigue while keeping upper-treble reach for air. The presentation favors balance over sparkle: detailed without the brittle edge many planars flirt with, and notably non-fatiguing over longer listens. Technical chops are strong for the class—clean, clear, and “planar-fast”—though instrument separation can lag behind pricier hybrids, and the topmost “crispy” sheen is slightly restrained.

On graphs and in practice, S12 Ultra reads as a refined take on modern planars—more bass weight, tidier 4–6 kHz, and better treble behavior than its siblings. Listeners hypersensitive up top may still prefer something like the S15 for a softer treble contour, while those chasing maximal separation may lean to sets like AFUL Performer 7 (with a spicier treble). With the usual planar caveat about unit variance and fit, this edition comes through as the standout of the S12 series: a clean, engaging, and genuinely high-value recommendation under $500.

Youtube Video Summary

Aful Performer 8 shows up looking like a kilobuck piece and delivers a balanced, clean, and effortless sound with a tasteful twist. Indie, acoustic, and ballads feel natural thanks to a slightly forward midrange, while vocals carry an airy, sparkly sheen that adds excitement without harshness. Strings come off rich and dynamic, and the overall presentation is super smooth, making long sessions easy.

The flip side: a smoothed 2–3 kHz region dials back ear-gain energy, so vocals, while present and airy, don’t project as openly as sets like Orchestra Lite or Studio 4. Soundstage sits average to above average with a closer, more intimate feel, and because the tuning is very flat, imaging and separation take a small hit on busy mixes. Bass is tidy—fast mid-bass with no bleed—but the sub-bass lacks rumble; compared to Blessing 3, low-end texture and tactility are a step behind.

Where it shines: some of the best treble in the ~$400 bracket (right up there with Studio 4), a cohesive tonality, and a versatile all-rounder vibe—great for J-pop/J-rock where it tames hot upper mids and adds body to female vocals. Not the pick for EDM/hip-hop or maximum slam—grab Quartet for that—but as a daily driver it’s a win. Grades shake out as Technicalities: A, Tuning: A+, Vocals: B, for an overall A; wish list would be stronger separation/imaging and a touch more sub-bass heft.

Youtube Video Summary

The Letshuoer S12 Ultra comes through as the smoothest tuning in the S12 family— a sub-bass boosted all-rounder with quick transients and satisfying rumble that makes pop, hip-hop, and EDM notably fun. Technical performance sits around earlier S12 variants, but treble detail is dialed back a touch versus the OG/Pro in exchange for a more natural timbre and less “planar-bright” edge. It’s the bassiest S12 to date, hitting with better texture, impact, and extension, while keeping imaging crisp enough to stay engaging rather than clinical.

Tuning tweaks tame the upper range: a cut past 1.5 kHz and an 8–15 kHz dip ease shout and sibilance, with air returning via a lift around 15 kHz. Vocals sit a bit pulled back and the treble is the least energetic of the series, which helps long-session comfort—though brighter, heavily produced tracks or songs with little low-end can still sound peaky if pushed. Best results come at ~65–70 dB; tip-roll toward clear or bass-supporting tips to smooth the top and reinforce the lows, while avoiding brightening tips that exaggerate energy.

Versus peers, S12 Ultra feels like a bassier, less shouty take on Supermix 4/Nova and a slightly more V-shaped, punchier alternative to Defiant. It’s not a value monster for sheer detail compared with cheaper planars (T10, F1 Pro, etc.), but the payoff is a presentation that’s more musical, smoother, and easier to live with. For listeners wanting added slam without losing the S12’s speed and airy sense of space, this version offers the most enjoyable balance in the lineup.

Youtube Video Summary

Aful Performer 8 takes the brainy crossover wizardry that made the P5 clean and pushes it harder. Inside sits 1DD + 7BA, a real RLC crossover on a circuit board, and a maze of 3D-printed acoustic tubes—~10 mm for mids, ~46 mm for mid-bass, and a wild 62 mm bass tube—used to time-align energy so attacks arrive together instead of smearing. In the ear it’s still compact and comfy (faceplate a touch wider), the stock cable is fine, the leather case is nicer, and the tip pack is basic. The kicker: a price around $379, delivering “flagship” brains without the usual sticker shock.

On music it comes off coherent and crisp, with vivid attack and heaps of detail that somehow never turn into icepicks—there’s treble presence for days, yet it stays smooth thanks to the crossover work. Bass isn’t for bassheads, but it’s punchy, tight, and confidently controlled; staging pulls a convincing side-distance trick where echoes and bounces feel placed in space. Tip-rolling proves unusually consistent—Dekoni, Render, and Sedna options all sound within ~10%—so the tuning stays intact. Net result: a full recommendation that makes the P5 feel redundant and puts this set in the conversation with favorites well above its price—because science made good things happen.

Youtube Video Summary

AFUL Performer 8 steps beyond the meme status with a 1DD + 7BA hybrid design at around $370, aiming squarely at the gap above Blessing-class sets. Build is solid: a decent but slightly stiff cable with pre-formed hooks and a standard non-recessed 2-pin layout; the highlight is the shell—medium-sized, long-nozzled, and notably secure/comfortable. Aesthetic is a touch busy, and the nozzle lacks a mesh, but overall ergonomics and seal are a clear plus.

Tonality skews neutral with a tasteful sub-bass lift, a slightly relaxed upper-mid, and a hint of lower-treble energy that reads as slightly bright without turning sharp. Technical performance is the draw: imaging, separation, and layering come through cleanly, while bass has good physicality; vocal lovers may wish for more midrange texture and timbre naturalness, which can feel a touch artificial. As a package, it’s a clean, somewhat exciting listen with strong spatial cues—4/5 stars feels right for the performance and price.

Youtube Video Summary

The Aful Performer 8 stands out for coherency, a clean, open presentation, and excellent tonality/timbre that suit competitive play. Bass is fast, well-textured, and deliberately restrained—trading slam for separation and clarity during chaos—while micro detail like reloads and shield cues remains intact. Imaging is the best of the roundup both horizontally and vertically, with strong depth perception (just shy of the pricier all-BA rival) and a stage that sits in the sweet spot: close enough to keep footsteps forward without feeling cramped. Occasional upper-treble bite appears, but never reads as fatiguing. As a 7BA + 1DD hybrid with solid ergonomics, it shapes a true wallhack-certified profile and looks poised to place high on the list—potentially edging past Orchestra Lite.

Context from the roundup: KZ ZOR overwhelms with sub/mid-bass, flooding mids and crushing separation/layering, so positional accuracy lags. Tin HiFi Elf goes the other direction—flat, shrill, and low-resolution—though basic imaging is serviceable. 7Hz Sonus (1DD+1BA) balances bass quantity with control; separation and layering are promising and likely to earn certification after further testing. The Sounds Avant (10BA) offers beautiful air and depth, but gets shouty and collapses under heavy action; BA bass and fit sensitivity don’t help. Net: only the Performer 8 and Sonus move on to full reviews, with the Aful clearly the top gaming pick of this group.

Youtube Video Summary

Final revision of the series brings a very coherent, slightly warmer presentation with treble pulled into safer territory and mids that feel a bit weightier. Ultra sits between the smoother S08 and the rawer S12 Pro, and it comes across a touch bassier than the graphs suggest. As a single-driver planar, it retains solid resolve and a natural, easy tonality that will suit most listeners, especially at the 169 price point.

Despite graphs looking similar to S12 2024, Ultra sounds smaller and flatter, with less transparency and dynamics. Soundstage is mainly left-right; height and depth are curtailed, so placement is not always in the right place on more spacious tracks. The smoother top end avoids harshness and makes long sessions comfortable, but the trade-off is reduced sparkle and air versus the 2024 tuning.

Versus budget planar standouts like KZ PRX, Ultra is a clear, smoother upgrade; versus S12 2024, it is the safer all-round pick but not as open or exciting. Dense mixes can nudge the bass toward a slight bloom and compress the center image. For most, this is the one S12 to buy; stage and transparency chasers may still prefer the 2024 version.
