Kiwi Ears KE4 VS BGVP NS10 Pro

Youtube Video Summary

Kiwi Ears KE4 is a hybrid 2DD + 2BA IEM around 199 dollars, built from medical grade resin with an ergonomic, contoured shell and a pocketable case. The cable is soft, non microphonic and generally very pleasant to use, though a modular plug option would have been welcome, and there is a bit of soft driver flex that some users may notice.

The sound signature follows a warm neutral meta tuning with a clear bass boost, smooth overall response and no major peaks or dips, which makes the tonality very versatile across many genres. Bass is all about slam and impact, with full bodied low end and satisfying sub bass rumble, while the lower mids add thickness and note weight so male vocals and instruments sound rich and hefty, even if the upper mids can feel a touch laid back at lower volumes. Treble extends well with an airy but very smooth presentation, zero sibilance and a relaxed, non fatiguing character that lets the KE4 work as an all day, easy listening set.

Technical performance is not on the level of the most detail focused competitors, but the KE4 holds its own with respectable detail retrieval, good timbre and a pleasingly soft transient character that suits the relaxed tuning. Sets like TruthEar Nova, Binary Chopin or Kiwi Ears Quintet will offer more bite, separation and vocal forwardness, yet they often give up some of the KE4s natural timbre and forgiving treble in return. For around 200 dollars this IEM functions as a benchmark warm meta tuned option, recommended for listeners who want impactful bass, natural vocals and a smooth presentation that still feels engaging once the volume is turned up a bit.

The BGVP NS10 Pro combines a solid metal shell, mmcx connection and modular cable with a lean, upper mid focused tuning. The dual dynamic drivers deliver a clean, punchy bass response with strong slam and sub bass extension that stays out of the midrange, so the presentation feels tight rather than boomy. Midrange is clear, forward and highly detailed, but the 2 to 6 kHz region carries extra energy, so female vocals, violins, flutes and bright piano notes can come across a bit too intense for listeners who do not already enjoy a very present midrange.

Treble sits in a sweet spot between dull and piercing, giving cymbals and high frequency detail good presence without stealing the show or turning harsh. Overall detail retrieval is strong for a mid fi set around 300 dollars, with good separation that keeps instruments distinct even in busy passages. The tonal balance ends up quite lean and energetic rather than warm, which suits cleaner, gentler recordings more than already hot or compressed mixes.

On the technical side the NS10 Pro offers impressive imaging with precise spatial cues and a stable sound field that makes positional information easy to follow, while the soundstage is respectable though not class leading. The punchy dynamics and constant sense of bass impact add excitement, but the elevated upper mids reduce long term comfort at higher volumes and limit genre versatility compared to more relaxed alternatives such as the AFUL Performer models. Overall, this is an engaging, detail forward hybrid for listeners who prioritise clarity, speed and slam over warmth and a laid back presentation.

Competitive audio matters: precise imaging, localization, and clear spatial cues drive better peeks, crosshair placement, and decision-making in titles like Apex and Valorant. Among the sets tested, the Moondrop Blessing 2 impresses with its premium unboxing, CNC stainless faceplates, and transparent resin shells, but more importantly with clean bass/sub-bass, vivid mids, and non-fatiguing treble. The stage isn’t claustrophobic and imaging remains pin-point, yielding an almost open-back-like sense of space for an IEM at its price.

The Dunu SA6 steps up build and versatility: UV acrylic shells with unique stabilized-wood faceplates and a high-quality cable with swappable terminations. Tonally it reads as a reference-leaning set with a touch more bass energy than Blessing 2, adding oomph without masking footsteps or micro-details. Separation stays clean during busy mixes, and even the bass-boost switch remains usable for games. This blend of fun and precision makes SA6 the easy choice for daily competitive play.

On a tight budget, the Tanchjim OLA shows surprising prowess: a single DD tuned around HRTF targets, aluminum shells with a partial window, and a balanced, footstep-friendly tonality. Stage runs closer and there’s slight ambiguity at certain front/back angles, but overall imaging and intelligibility are excellent for the price, plus the mic cable adds everyday utility. Summary: SA6 for the best mix of immersion and accuracy, Blessing 2 for a cleaner tilt with wide spatial cues, and OLA as a highly recommended budget option for competitive gaming.

Youtube Video Summary

Kiwi Ears KE4 is a $200 hybrid (2DD+2BA) that showcases the so-called “new meta” tuning—more body in the lower mids and a calmer lower treble versus the Harman Target. Packaging is simple: a pocketable case and bespoke silicone tips (usable, though even shorter tips can improve comfort). The cable handles well but feels a bit thin/kinky with heat-shrink earhooks, and the shells look plain, prototype-like. Fit is secure and comfy with a semi-custom shape, albeit a touch thick, so they can protrude from the ear.

Sonically, KE4 delivers a warm, low-contrast midrange that makes vocals sound natural and well-placed, with a pleasant mid-treble “frothiness” adding texture. Bass quantity leans on the mid-bass, but quality is the weak spot—soft/bloomy and a bit poofy, lacking density and punch, which can dull drive on bass-heavy tracks. Imaging is decent, treble is safe and balanced (not sharp or dark), and overall technicalities are respectable without chasing wow-factor.

Against peers: Truthear Hexa mirrors the new-meta mids with tighter, better-controlled bass; AFUL Explorer is more engaging with tighter slam and slightly crisper treble; the Harman-leaning Binary Chopin brings the best bass attack. KE4 is a strong choice for vocal-first listening and a clear example of the new meta, but the bass bloom can hold it back across a broad library. Verdict: a very solid 4/5 stars.

Youtube Video Summary

Build & accessories: understated box, a surprisingly nice cable with a “juicy” feel and flat 2-pin connectors, plus extra filters. The stock tips are the weak link—thin out note weight and feel downright horrific, so a tip swap is recommended. The medium-to-large shell is a highlight: secure fit, comfy nozzle size, and a handsome faceplate that looks premium in ear. Overall ergonomics and finish scream daily-driver friendly.

Sound: impactful, well-judged bass, lively upper mids, and a touch of upper-air jank; for $200 it’s a strong value with a clean, modern JM1-style tuning. Easily the most convincing Kiwi Ears to date: more balanced and natural than Quintet (which pushes upper mids/10 kHz energy), far more sensible than the treble-shouty Forteza, a clear upgrade over budget options like DLS and the tiny, poorly packaged Singolo, and less fatiguing than the bass-and-upper-mid heavy Melody. Against $200 benchmarks, KE4 becomes a new reference—cleaner male vocals and better build than “Chopin,” and a tighter low end plus tidier mids than AFUL Performer 5. Trades blows with Hype 4 at a fraction of the price; those craving a pricier step-up in the same vein can eye HiSenior Mega5EST. Measured verdict: Tier A, 3-star, 8.8 for tone—good imaging, solid soundstage, gamer-friendly, not flawless but genuinely excellent once re-tipped. A handsome, comfortable set that delivers outstanding value for newcomers and gift-givers alike.

Youtube Video Summary

Kiwi Ears KE4 drops at $199 and comes across as the best-tuned Kiwi Ears yet. Unlike the Orchestra Lite with its sub-bass roll-off or the budget Cadenza that skews a bit dark, this set keeps the sub-bass present and tight. Compared to the Dolce (energetic with more mid-bass) and the Quintet (politer bass, lighter upper-mids/late treble), KE4 adds more slam while smartly tucking the mid-bass so vocals stay clean. It’s a tuning that both looks right on the graph and lines up with real-music listening across hip-hop/R&B, rock, and acoustic cuts.

Low-end tests—808 drops and bass-guitar lines—hit clean and natural, and kick-drum transients keep their body instead of drying out. Female vocals get clarity without mid-bass haze, while male vocals avoid thinning—nicely balanced through the mids. The treble is managed with some late-treble roll-off, avoiding glare while preserving harmonic bite for guitars and cymbals over longer sessions. Net result: no qualifiers, no obvious weak spot, and performance that competes hard at $199. Easy recommendation and a frontrunner for the brand’s lineup to date.

Youtube Video Summary

Kiwi Ears KE4 plays a warm-leaning, smooth and relaxing set at mid volume with slightly laid-back vocals and a good sense of space. The real trick is volume scaling: turn it up and the upper-mids/treble step forward with more detail without becoming shouty, while the bass grows thumpier and digs deeper. A 1 kHz scoop plus a tasteful ~3 kHz lift (gentler than Harman) keeps vocals extended yet non-fatiguing; the trade-off is vocal power/weight, which stays a touch mild compared to sets like RS5.

Driven by dual dynamic drivers, the KE4’s low end is among the best under $200 for texture, slam, and note weight, making the tuning feel full and grounded. It’s not as razor-quick in transients or as surgical in imaging as certain planars or techy hybrids, but the payoff is a more natural timbre. Treble sits in a balanced pocket—neither splashy nor dark—with none of the plasticky shimmer or planar/PZT glare.

Against peers: Supermix 4 and Quintet (and even the cheaper “Conta”) push more micro-detail and separation; Orchestra Light is the cleanest/most neutral but softer in bass and more complete in vocals. Versus CKLVX and PULA, KE4 trades their airy, sometimes peaky sparkle for a smoother, more grounded presentation and richer bass grip. Compared with Explorer, KE4 offers a clear step up in technicalities and low-end authority, while Explorer stays more intimate. Net: not the new “benchmark” at $200, but as a crank-it-up, musical all-rounder with standout bass and fatigue-free top end, KE4 is an easy favorite.

Youtube Video Summary

Kiwi Ears KE4 is a 2DD + 2BA hybrid touting an isobaric subwoofer system and “sub-bass impact and slam.” The reality doesn’t match the brochure: the $200 package feels plain—simple box, basic case, few tips, and a generic 3.5 mm cable—while the tuning comes across as safe to a fault. Marketing promises of kick drum thump and bass guitar presence give way to a presentation that’s competent but uninvolving.

On music, the low end skews mushy rather than tight, transients lack bite, and the overall tone reads flat—the kind of “waiting-room” vibe that prompts a double-check of DSP settings. Even with a strong seal from premium tips, energy and excitement refuse to show up; it’s “fine ingredients, bland dish.” Technicals aren’t a disaster (it’s not unclear), but fun factor feels negative, recalling ultra-neutral sets like Softears Studio 4S that impress more than they engage. Verdict: about a 6/10 (maybe 7/10 on a generous day), with better value found in a cheaper Kiwi alternative at roughly half the price—skip the KE4 if musical thrill is the goal.

Youtube Video Summary

$199 hybrid with 2DD+2BA, the Kiwi Ears KE4 pairs a glossy, translucent faceplate with an ergonomic 3D-printed resin shell for all-day comfort. The stock 3.5 mm cable is light and flexible, the new silicone tips seal well, and spare filters are included. Sonically it follows the diffuse-field “new meta” tuning popularized by sets like Moondrop x Crinacle Dusk, Dunu Da Vinci, and Mega5 EST—but arrives as the most affordable in that crowd. Tonality leans a touch warm with a smooth upper-mid/treble that keeps gunshots from sounding harsh; for music, the presentation feels immersive and lively at the price.

For competitive play, performance varies by title. In Valorant: B, horizontal imaging and depth cues are convincing, and footstep “thumps” pop through clearly, aiding reaction time. In Apex Legends: B–, basic imaging and map awareness are fine, but busy fights expose separation/layering limits and a slight haze to light taps and micro-details. In Call of Duty: C+ (borderline B–), clarity and detail retrieval dip during chaotic moments and the game’s occlusion/breathing effects mask cues more than preferred. Overall, a stylish, comfortable DF-tuned IEM that’s great for music and a solid pick for Valorant, but not the first choice for top-tier Apex/CoD grinders—though it still makes the Wallhack Certified list.
