EPZ P50 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

The EPZ P50 comes in hot as a new tribrid and a potential $200 neutral benchmark, trading sterile restraint for a more vocal-centric presentation. Versus the MEGA5EST, vocals sit a touch more forward—adding emotional weight and clarity—while the MEGA5EST still edges it on sheer smoothness and EST “air.” Compared to Meteor, the P50 fills in the lower mids, dials back 1–3 kHz glare, and opens the top end a bit; Meteor stays a hair softer up top. The catch is bass: the P50’s DD is competent but not a sub-bass shaker—expect clean rather than authoritative slam.

Against peers, the P50 sounds fuller and more natural than Supermix 4 (which is brighter and more “hi-fi” energetic), and it trades blows with Odyssey: Odyssey brings better bass texture and treble micro-detail, while the P50 delivers superior vocal clarity and a touch more air. It excels at mid-volume listening—Volume S needs more gain to bloom—and outclasses lighter, air-tilted sets like “K4” style tunings when male vocals or body are the priority. Accessory game is strong too: a nicer cable and a genuinely sturdy hard-leather case sweeten the deal. Not the most “unique” flavor and not for bassheads, but as a balanced, clean, vocal-forward option around $200, P50 is an easy recommendation for those chasing neutrality without the vanilla.

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

The EPZ P50 is a five-driver open-back hybrid (1DD + 2BA + 2 micro-planars) that arrives with a solid accessory kit and a sensible price. The tuning is the highlight: a vocal-centric balance that avoids the over-energetic tilt of some Harman-leaning sets, while keeping a clean background and strong clarity. Sub-bass is trimmed for control, mid-bass adds body, and the result is natural male vocals and a presentation that feels both transparent and organized.

Upper mids rise earlier for familiar presence, and treble is extended by the micro-planars yet kept in check for wider appeal than brighter peers. Resolution is high for the class and the set can be revealing, sometimes asking for a touch more volume and occasionally sounding a bit unforgiving on hot masters. Bass is snappy rather than booming, trading rumble for speed and definition to keep the midrange clean.

Stage and imaging are standouts: spacious, precise, and helped by bass control and the open shell design. Compared with typical u-shaped ~$200 hybrids, this tuning prioritizes mids and coherence, showcasing a clear, extended top without brittleness. As a sub-$100 tribrid, the P50 delivers impressive value and feels like a sign of what is to come in this segment.

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.
