Sennheiser IE600 VS Moondrop Meteor

Youtube Video Summary

$700 buys a compact, 3D-printed metal single-DD that looks mature and fits like a glove. The IE 600 arrives with two cables (3.5mm and 4.4mm) that are thin and comfy but a bit microphonic thanks to stiff, moldable ear hooks. Connectivity is MMCX, yet Sennheiser’s slightly non-standard recess limits third-party cable options. Isolation is a touch below average, but the tiny shells seat past the tragus, stay secure, and even work as a sleeping IEM. The real facepalm is the stock tips—especially the silicone set with collapsing walls. Foam tips are usable (and subtly affect treble), but the easiest fix is Final E-type tips, which keep the incisiveness while curbing sibilance better than Moondrop Spring Tips.

Tonally, think tasteful V-shape: a sub-bass-weighted low end with just enough mid-bass wallop for body, natural and appropriately forward mids, and spicy, well-extended treble. The draw is the technical ride—top-to-bottom texture, punch, and an almost visceral snap. Bass is a standout: deep, delineated rumble that doesn’t smear the mids yet feels physical on everything from EDM to Fleetwood Mac. Treble gives cymbals real weight and timbre (a spot where many sets thin out), while stage is bigger than average with solid imaging—cohesive rather than gimmicky holography. Compared side-by-side, it’s bolder and more contrasty than a warm-neutral Zen Pro, and far more physical than the airy, sterile-leaning Moondrop S8, yet it keeps vocals clean and convincing.

Quibbles exist—awful stock tips, a touch of treble bite depending on fit, and that picky MMCX—but the core experience is special. With a quick tip swap, IE 600 delivers endgame-within-reach performance: exhilarating bass quality, incisive treble, natural mids, comfort for hours, and virtually no deal-breaking caveats. At $700 it’s not cheap, but it competes fearlessly with far pricier IEMs and feels like a set to buy once and be done.

Youtube Video Summary

The $500 Moondrop Meteor packs an oversized 13mm dynamic driver for bass, two balanced armatures for mids, and four micro planar drivers for treble. Objectively, its frequency response is fantastic—neutral with a tasteful sub-bass lift and exceptionally smooth, reserved treble that avoids harshness. Vocals sound natural and forward without edginess, and high-frequency percussion retains realistic timbre. Build quality impresses with a glossy, semi-transparent shell and a unique "meteorite" side panel, though the bulky design compromises fit stability versus sleeker Moondrop models. Accessories feel recycled from cheaper offerings, including a basic case and functional but kink-prone swappable-termination cable.

Subjectively, however, the Meteor feels unengaging. Its bass lacks punch and definition despite the large driver, coming across as soft and undynamic. Combined with the relaxed treble, this results in a lackluster sense of separation, layering, and imaging—music sounds cohesive but lacks incisiveness and visceral impact. While tonally balanced, the presentation is overly cautious, missing the excitement expected at this price. Even Moondrop’s own $360 Dusk outperforms it with tighter bass, sharper imaging, and greater overall engagement.

Comparisons highlight its shortcomings. The Dunu DK-31BD offers superior bass impact and more expressive treble at the same price, while the HiSenior Mega5EST delivers better definition and layering despite a warmer tilt. Ultimately, the Meteor’s excellent tuning can’t compensate for its dull technical performance. It’s a competent monitor but fails to justify its cost against rivals—or even Moondrop’s cheaper offerings.

Youtube Video Summary

Moondrop’s new “flagship” Meteor lands with a decent first impression: a natural planar timbre that avoids the overly sizzly or peaky upper ranges found in rivals, and clean, forward vocals that shine on ballads at mid volume. The overall tuning sits neutral with a tilt toward female vocals, and technical performance is good—competitive but not class-leading at its bracket. Fit is on the thicker side with a quirky curve, so a demo is wise. The catch: the low end is tame to the point of feeling clinical, lacking slam, authority, and bass-guitar/drum texture in busier rock and metal. Treble is balanced with some extension, yet it lacks air and micro-nuance, making the presentation feel less special. Net result: more a side-grade to Dusk than an upgrade—and at $500+, that stings.

Energy genres expose more issues: the boosted 1–3 kHz pushes vocals shouty past ~60–65 dB and the set doesn’t scale well, especially with K-Pop/J-Pop and mainstream pop where even the Dusk can sound more engaging with better contrast and more low end. Value is the real problem: the EPZ P50 at roughly half the price brings more bass, more air, and similar accessories; competitors like IO Volare (4×EST), Oracle Mk1, or a sale-priced Variations offer smoother, airier treble, finer micro-detail, and better all-round balance. The Meteor’s use of micro-planars instead of ESTs, plus unchanged accessories (think Aria 2/Dusk level), makes the premium hard to justify. Overall, it edges sets like “Brain Dance/Damage” on timbre but gives up technicalities and versatility. Recommendation: skip—grab the P50, go IO Volare/Oracle/Variations, or EQ a Variations (fill the scoop, ease 1–2 kHz) for a result that outclasses Meteor. Bonus note: Moondrop’s new flagship Psyche also gets side-eyed—$2,000 without ESTs feels more cash-grab than value.

Youtube Video Summary

Moondrop Meteor arrives as a hybrid with one dynamic, two BA mids, and four treble planars, now priced around $550. The shell is massive but well-contoured resin with a flat 2-pin connector; fit can be good after some tip rolling, though the nozzle runs large. The stock cable feels cheap for the price and the accessory pack is underwhelming—no DAC, a basic case—so the unboxing doesn’t add much value.

Tonally this is a treble-focused set that sounds clean, clear, and crisp, with pleasing air and microdetail. Bass is the weak link: quantity and slam are light, leaving dynamics and note weight on the lean side; lower mids could be richer. Graphs show typical Moondrop-leaning tuning that sits close to target but wants ~2–3 dB more bass. It measures stable with impedance, which, paired with precise imaging and tidy staging (good, not “huge”), makes it a plausible studio monitor-style choice.

Against peers, Variations brings more energy and is the safer pick; Moondrop’s own Concerto and even Caden-line sets feel fuller down low. Cheaper rivals like EPZ P50 and AFUL P7 offer more fun, while HiSenior Mega 5 EST and Softears Volume S present stronger overall value and bass presence. Verdict: a solid, airy detail-getter with attractive aesthetics, but not an upgrade to bass-richer favorites; recommended on the used market or with a discount, and an easy skip at full MSRP if seeking warmth and impact.
