The FlipEars Legion makes a commanding entrance with its striking Roman legionnaire-inspired design, featuring jewelry-cast rose-plated brass faceplates hand-painted by master artisans in Bulacan, Philippines, ensuring each unit is a unique masterpiece. While the substantial resin housings may challenge smaller ears, the included Eletech Baroque tips and pliable cable contribute to a surprisingly secure and comfortable fit over time. Unboxing feels luxurious, with a premium leather case and meticulous packaging underscoring FlipEars' commitment to craftsmanship.

Sonically, the Legion leverages its innovative tribrid driver system to deliver thunderous, tactile bass via a custom dynamic driver and EarQuake bone conduction unit, creating visceral sub-bass rumble without muddying the midrange. The midrange remains lush and articulate, presenting vocals with natural warmth and instruments with rich texturing, while the SPARK electret tweeter adds refined, fatigue-free sparkle to the highs. This synergy results in a cohesive, immersive sound signature that prioritizes musical engagement over analytical sharpness, making complex tracks feel both powerful and nuanced.

Technically, the Legion punches above its price point, boasting a holographic soundstage with precise instrument placement and exceptional layering that rivals models costing twice as much. Its imaging is pinpoint accurate, rendering subtle ambient cues and dynamic shifts with effortless clarity, while the bone conduction driver enhances physicality and depth without sacrificing control. Though its bass-forward tuning might not suit treble purists, the Legion excels as a reference-grade all-rounder for those seeking technical prowess paired with relentless musicality.

The Eminent Ears Emerald is positioned as the most accessible model in the brand’s Gemstone series, designed by a small Hong Kong team of enthusiasts as a more attainable entry into their line-up. It uses a tribrid configuration with 1 dynamic driver, 2 balanced armatures and 1 bone conduction driver, an 8Ω impedance and 106 dB/mW sensitivity, making it relatively easy to drive from portable sources. The semi-transparent shells, deep-fit ergonomics and stock Vortex copper-silver cable with 4.4 mm termination are aimed at long-term comfort and stable contact for the bone-conduction element.

Sonically, Emerald follows a neutral-with-bass-boost approach: bass is deep and weighty, with the bone conduction driver adding tactile presence that enhances immersion in live recordings and rhythm-heavy material. Despite the emphasis on low frequencies, the midrange remains forward and clear, giving vocals a slightly bright, energetic presentation that suits pop and vocal-centric music. Treble is tuned on the smoother side: extension and air are adequate rather than spectacular, prioritising fatigue-free listening over maximum sparkle and micro-detail.

Technical performance is solid for its segment: soundstage has above-average width with convincing center focus, and imaging is precise enough to separate instruments and backing vocals, though ultimate resolution and treble refinement lag behind top-tier tribrids at higher prices. At an asking price around the mid-to-upper hundreds, Emerald offers a comfort-focused, warm and engaging tuning with competent technicalities rather than chasing absolute resolution, making it a good fit for listeners who value bass impact and vocal presence over analytical treble detail. In value terms it sits as a well-executed, musically oriented option in the higher price bracket, but not a price-to-performance outlier when compared with more aggressive competitors around and below the same budget.

Fun, bass-forward WV tuning with surgical treble control and standout 3D imaging; hard-hitting yet clean at volume. Pricey but executed with uncommon finesse. Powerful, fast mid-bass with excellent 3D imaging/layering and controlled, non-fatiguing treble. Lower mids can feel a bit thick and the bass-forward balance plus the premium price will not suit neutrality seekers.
Youtube Video Summary

FlipEars Legion combines a large dynamic driver, an earquake bone conductor and a spark electric tweeter into a WV-shaped tuning built around a long-arc bass shelf. Sub-bass is deep but controlled, mid-bass hits hard with speed and cleanliness, and the upper range remains vivid yet separated. Imaging presents with depth and a notably 3D placement that feels different from typical hybrids.

The bass sits lower in the stage, freeing the mids for clarity and layering; notes have body without turning boomy, and the set tolerates volume without glare thanks to surgical dips around the presence region. Vocals are slightly thick but well-positioned, while the bone conduction adds a subtle sense of space and psychoacoustic texture that helps separation.

Treble behaves like a tempered V: selective peaks restore energy where needed after a 5 kHz dip, avoiding harshness while keeping cymbals crisp and detail retrieval high. The overall effect is a fun, hard-hitting presentation that recalls high-impact references such as the 64 Audio Trio, but with heavier low-end weight and unusually fine frequency control.

Bass-focused Bone Conduction done properly! Rumbles and Buzzes in your ears with no annoying buzz or tonal issues. Not the best technical performer, but absolutely GORGEOUS Shells.
Youtube Video Summary

FlipEars Legion brings serious boutique flair: a wax-sealed letter, a plush leather case, and a premium 4.4 mm cable set the tone, while the hand-finished brass faceplates (rose-gold plated, enamelled by a jeweler) scream showpiece. The resin shells feel rock-solid and quite hefty (~12 g each), yet the earhooks distribute weight well for multi-hour sessions. Fit skews large—small ears will struggle, and shallow seals blunt the bone conduction effect. Accessories are minimal but tasteful (L-size Baroque tips, cable tie), fitting the boutique vibe. Build, finish, and the whole Spartan aesthetic? Sub-Zero cool.

Under the hood, Legion is a tribrid: custom dynamic for lows, a bone-conduction driver active through bass/mids, and a custom electret tweeter up top. The signature is unapologetically V-shaped. Bass is the star—tactile, rumbly, and subwoofer-like without boom or weird BC artifacts; kick drums and EDM drops thump with grinning authority. Lower mids gain pleasing warmth and body, while center-mids can sit a touch pushed back on acoustic and vocal-centric tracks. Treble is crisp and airy, smooth yet detailed, avoiding fatigue while keeping cymbals and harmonic sheen lively. Staging benefits from BC with a wider, more separated image and engaging depth when the recording allows.

Put simply, this is the polished, modern take on that classic fun V-tune: all the excitement, far fewer compromises. For EDM, hip-hop, pop, rock and anything bass-forward, Legion is a party in the ears and a compelling endgame choice at its $850 pre-order tier. Those chasing neutral mids, analytical focus, or small-ear ergonomics should look elsewhere; everyone else gets glorious low-end slam, smooth sparkly highs, and boutique craftsmanship that feels special. On the Audio Amigo scale: “This is brilliant.”

What this does well, it does very well. Fun set.
Youtube Video Summary

FlipEars Legion stakes its identity on a bold, mid-bass–driven fun signature with a bone-conduction twist. The shell is huge and may challenge small ears, the 2-pin sockets are deeply recessed, and the stock 4.4 mm cable and premium case feel thoughtful and upscale. On the graph, there’s a notable dip through the mids that can sound a touch hollow, plus energy around 4 kHz and 8 kHz that adds bite and sparkle; in practice the set delivers big slam, airy extension, and surprisingly solid imaging for a BC-assisted tuning. A light EQ nudge to the upper-mids/lower-mids tightens tonality and pushes technicals up a tier.

Positionally, Legion reads as a “fun daily driver” rather than a sterile studio tool. Compared with similar BC-flavored sets, it feels more controlled than the Z Empire “party” tuning, and markedly more coherent than cheap experiments like KB Ear KBO2. Against safer picks, Monarch Mk I remains the clean, glassy option, while ThieAudio Origin is a safer all-rounder; Legion, however, brings deeper sub-bass and livelier presence with more character. Versus Triton, Legion’s upper-air/presence has better flow; versus the high-ticket Muse, Legion trades a bit of refinement for long-session comfort, dodging fatiguing 6 kHz glare.

Overall, this is an engaging, charismatic tribid that rewards listeners seeking bass heft, contrast, and BC texture without descending into chaos. It’s not the safest first $800 pick given the mid dip and fit quirks, but as a statement piece from FlipEars it feels well priced, well built, and easy to recommend to those prioritizing musical thrill over strict neutrality—especially with a touch of EQ to tidy the mids.

Balanced, vocal focused bone conduction IEM with tight sub bass, smooth refined treble, and versatile tuning that suits many genres. Packaging feels slightly less premium than the sound and price might suggest. Balanced, vocal centered tuning with controlled sub bass, smooth refined treble, and strong genre versatility. Packaging and visual presentation feel less premium than the price, and technical performance stops short of the most holographic and resolving competitors.
Youtube Video Summary

Eminent Ears Emerald delivers a bone conduction implementation that prioritizes control and balance over sheer bass quantity, with a sub bass focused shelf that feels deep and satisfying yet avoids mid bass bloat or muddiness. Bass notes hit tight and punchy with fast decay and excellent elasticity, contributing to a relatively wide soundstage and clean separation from the midrange, while the overall tonality remains more even handed than the typical bass head bone conduction tuning. The lower mids are slightly attenuated, but an upper mid emphasis around the vocal region keeps singers upfront and intimate without sounding shouty, creating a vocal centered yet balanced presentation that works across many genres.

The midrange is a clear highlight, offering polished and slightly bright but natural vocals that have full body, strong verticality, and a three dimensional feel, avoiding any sense of hollowness. Instruments in the midrange are rendered with clean layering, a touch of creaminess to strings, and convincing timbral richness, allowing them to blend coherently while still maintaining realistic separation. Treble has been refined compared with earlier prototypes, now sounding smooth, transparent, and articulate with respectable extension and an airy character that keeps sibilance in check while still adding sparkle and openness to the stage.

Technically, Emerald offers solid resolution, a relatively wide stage, and clear separation, though ultra fine spatial detail and ultimate air still favor the more expensive Audio Origin comparison partner. Compared with that more V shaped, bass heavier set, Emerald comes across as more balanced, vocal focused, and genre flexible, making it an appealing gateway into bone conduction for listeners who usually prefer neutral leaning tunings but want to sample this driver technology. At around 600 USD, the combination of controlled low end, natural and detailed vocals, and well integrated treble justifies a solid 8 out of 10 rating within its price class, especially for listeners who prioritize vocal clarity and balance over sheer slam.
