Best IEMs under $4000

Softears Enigma

• Gizaudio Axel: Endgame-level detail paired with great tonality.  Exceptional detail, high-quality bass, balanced tonality, and excellent timbre.  The bass has a fast decay.
• Web Search: The Softears Enigma is a flagship tribrid IEM using a 12-driver array (2DD+6BA+4EST) with a hybrid 5-way/4-way crossover and an aluminum shell; the package also includes a premium Effect Audio cable....

Elysian Annihilator 2023

• Gizaudio Axel: Hands down, my favorite IEM.  Powerful, impactful bass, the best treble I’ve experienced in an IEM, endgame-level detail.  The bass might be too much for some people.
• Jaytiss: Treble extension is insane, I always think I'm over it, but I may never be over it.
• Precogvision: More of an all-rounder with better bass compared to the 2021 version, sacrifices some soundstage.
• Tim Tuned:  More defined bass than 2021 version  2021 is cleaner and more open sounding
• Smirk Audio: Top-tier resolution with world-class treble. Great dynamics. Could use better bass texturing. An exciting listen.
• Web Search: The Elysian Annihilator 2023 delivers a distinctive U-shaped signature, prioritizing an ethereal, hyper-detailed treble that remains its crown jewel. The dual electrostatic drivers produce a...
• Head-Fi.org: 14 community members have rated the Elysian Annihilator 2023 at an average of 4.5/5 on Head-Fi. Overall sentiment: Outstanding.

Fort Ears Mefisto

• Smirk Audio: Demoed with "Temptation" cable.
• Head-Fi.org: 2 community members have rated the Fort Ears Mefisto at an average of 5.0/5 on Head-Fi. Overall sentiment: Masterpiece.

Thieaudio Valhalla

• Jays Audio: TOTL all-rounder with "endgame" tech across the board, a better tuned U12T with better bass texture
• Jaytiss: Big fan, but lacks fantastic air like some other sets.
• Super* Review: I'm really tempted to go out and buy one of this things for myself - if it fit me even better, I probably would.
• Fresh Reviews: S tier for COD, borders A- for other titles
• Shuwa-T:  Deep bass despite all BA set, techs carry this set more than the overall tone  Treble is mushy for something with so many BAs, not for high frequency enjoyers
• Bad Guy Good Audio: ThieAudio Valhalla comes in hot as a true flagship challenger: a titanium shell housing 19 drivers — 14 “Sonion” and five “Knowles" —and a price planted in the ~$2K bracket. This tier...
• Head-Fi.org: 4 community members have rated the THIEAUDIO Valhalla at an average of 4.8/5 on Head-Fi. Overall sentiment: Exceptional.

Elysian Annihilator 2021

• Crin: Elysian Annihilator 2021 presents a highly balanced yet distinctly treble-forward tuning: energetic upper mids paired with world-class treble that delivers striking clarity , microdetail, and...
• Precogvision: Agressive listen with excellent resolution and, currently, the only true implementation of the EST drivers.
• Tim Tuned:  Speediest Treble, well extended, high details  Midbass a bit too much for me
• Shuwa-T: Comment: Perfect for treble heads.  Extremely well tuned set with incredible technical performance and extension  Treble may be a little too spicy
• Nymz: Usual agressive and saturated Elysian house sound with the best treble ever.
• Z-Reviews: Brushed titanium Elysian Annihilator (2021) comes dressed to impress: a slick presentation with SpinFit tips, a plush micro-suede case, and a flashy gold cube 4.4 cable termination. The shells are...
• Yifang:  Tonal excellence for some genres e.g EDM (including hardstyle, DnB, Melodic Dub, etc), or J-Pop and high-pitched female vocal stuff. Almost unmatched treble performance, and highly technically competent.  Bass quality could be improved on, mids aren't ideal for male vocals or lower toned instruments.

Canpur CP622B

• Jaytiss: A good set, but lacks magic for me to justify keeping.
• Smirk Audio: Highly technical with great tuning and vocals. Punchy mid-bass with great sub-bass extension. Can sound somewhat unexciting and dry on some sources. Cons: Poor quality stock cable.
• Shuwa-T:  Similar to the Storm, but with greater focus to bass dynamics at the cost of less clarity  Price Price
• Bad Guy Good Audio: Canpur CP622B is positioned as a true apex set among today’s ultra-high-end IEMs—think Storm, Grand Maestro, Pearl, Multiverse, RN6—where differences are subtle and taste-dependent, not...  Resolution and tactile slam with not ultra boosted bass. brilliant tuning. Tactility only shows under extreme bass hits between 50 and 100Hz. Not sure why? Otherwise very oudiophile replay of rhythm section
• Yifang:  Tonally excellent and technicalities are fantastic. Works as an all-rounder with little to no flaws.  Mids could be a little better, BCD effect could be improved on.

7th Acoustics Asteria

• Precogvision: Pretty much the closest to a tonal panacea that I've heard only held back by the bass.
• Web Search: The 7th Acoustics Asteria is a hybrid flagship built around a 10 mm dynamic driver for bass and twelve balanced-armature drivers covering mids through super-treble (5-way crossover), packaged in a...
• Bad Guy Good Audio: 7th Acoustics Asteria arrives as a limited run of 77 units at around $3,800 , presented in a numbered box with premium trimmings. The shells are described as the most beautiful seen in the...  As technical as a PMG SE but smooth like an RN6 (engaging mids) Flawless for my library

Empire Ears Raven

• Jays Audio: V/W Shaped. Energetic treble. Great tech. Fun bass and engaging signature. Overpriced?
• Precogvision: Sounds quite hi-fi and grand sounding, but coherency could use work - bass is distinct from the EST tweeters.
• Head-Fi.org: 3 community members have rated the Empire Ears Raven at an average of 4.7/5 on Head-Fi. Overall sentiment: Exceptional.

FATFreq Grand Maestro

• Jays Audio: The best basshead set. That is all. EXPENSIVE. If you just want bass HBB Punch way better value.
• Jaytiss: Is one of those sets that can do it all. Very impressive.
• Web Search: The FATFreq Grand Maestro offers a highly adaptable sound signature through its NOAH modules and vocal switches, enabling four distinct tuning profiles. The black NOAH module emphasizes sub-bass...

• Head-Fi.org: 7 community members have rated the FatFreq Grand Maestro at an average of 5.0/5 on Head-Fi. Overall sentiment: Masterpiece.

• Shuwa-T:  Feels like a remastered VX in terms of clarity and staging  The tonality is too off for regular listening, timbre is also off in general
• Head-Fi.org: 10 community members have rated the Forte Ears Macbeth at an average of 4.6/5 on Head-Fi. Overall sentiment: Outstanding.

Kinera Imperial Loki

• Jays Audio: Super clean and clear sound. Beautiful vocals. Everyhting is extremely well balanced. No special sauce tho.

• Web Search: The Kinera Imperial Loki delivers a technically impressive W-shaped signature that balances sub-bass depth, vocal clarity, and sparkling treble extension. Its standout feature is the bone conduction...
• Nymz: Great bass texture with slightly hot upper mid-range and well extended treble. Remarkable technical performance.
• Head-Fi.org: 6 community members have rated the Kinera Imperial Loki at an average of 4.7/5 on Head-Fi. Overall sentiment: Exceptional.

64 Audio Tia Trio

• Crin: A more correct sounding version of the Fourte with slight cutbacks in staging and sheer resolution.
• Precogvision: Rich bass and out-of-head imaging.
• Super* Review: The tia Trio comes across as a hybrid with personality: rich, thick, and warm, with slightly forward treble that adds air without tipping into the harsher edge heard on the U18t. Vocals are ...
• Nymz: Best bass texture ever. Gorgeous treble extension, stage and imaging. Coherency and timbre a bit off. Upper mids/lower treble could be better. As amazing as it is, I couldn't fully connect with it...
• Audionotions: Phenomenal bass texture and quality. Mids are good if not great - I don't have much to nitpick about them - good note weight and excellent clarity. Treble is very sparkly and airy though some may...

Campire Audio Clara Ti

• Smirk Audio: Muscular bass with large bass notes. Male vocal timbre slightly odd, female vocals are nice. Some vocal grain present. Decent overall techs. Cons: Buy the non-Ti version for $1k less.
• Web Search: Campfire Audio Clara Ti is the Titanium Launch Edition of Clara—limited to 50 units—with a 3D-printed titanium shell and an included 8-wire 4.4 mm cable; it retains the same sonic profile as the...

FiR Audio Radon 6

• Jaytiss: Solid set, enjoyable, fun.
• Smirk Audio: Engaging bass, decent mids, and vibrant highs. Suffers from coherency issues. Mids are a touch veiled. Decent staging except for depth.
• Head-Fi.org: 6 community members have rated the FiR Audio Radon 6 at an average of 4.9/5 on Head-Fi. Overall sentiment: Masterpiece.

Alpha Omega Omega

• Head-Fi.org: 2 community members have rated the Alpha Omega: OMEGA at an average of 4.5/5 on Head-Fi. Overall sentiment: Outstanding.

64 Audio Volur

• Jaytiss: 64 Audio's finest.
• Super* Review: If you are a lover of bass, this is a good option. Does not sacrify the rest of the sound signature
• Smirk Audio: Well-textured, satisfying bass. Vocal timbre is slightly off. Upper-treble peak can get a little hot. Cons: Unnatural vocal timbre.
• Fresh Reviews: Great IEM but big price. Not Huge Gain
• Head-Fi.org: 3 community members have rated the 64 Audio Volr at an average of 4.7/5 on Head-Fi. Overall sentiment: Exceptional.

Letshuoer Cadenza 12

• Jays Audio: A better version of the U12T vocal/tuning wise, no mid scoop and wonkiness. (#1 or #2 vocals for me). Vocals are sweet, extended, open, airy, but also never fatiguing, and naturally weighted. No BA...
• Jaytiss: Great timbre good on classical. Detailed and analytical, but too Safe.
• Precogvision: More 'musical' tonality with a touch of spice in the treble. Technicalities could use work for the price.
• Tim Tuned:  One of the best treble-head set. Lots of micro details  Treble will be too much for some
• Smirk Audio: Bouncy, liquid-like bass. Well-bodied, analogue mids and extended highs. Great staging on all axes. Decent resolution. Excellent all-rounder.
• Web Search: The Letshuoer Cadenza 12 delivers a balanced sound signature with a slight warmth in the low end, providing clean and textured bass that avoids overwhelming the midrange. Its midrange presentation is...
• Z-Reviews: Letshuoer Cadenza 12 goes full flagship spectacle: a 12-driver per side build (1 dynamic + 11 BA from Knowles/Sonion ), six-way crossover , and heavy metal shells that feel like a prize out of a...
• Head-Fi.org: 17 community members have rated the Letshuoer Cadenza 12 at an average of 4.6/5 on Head-Fi. Overall sentiment: Outstanding.
• Yifang:  Tonally excellent with good technicalities, works as an all-rounder. Bass quality is unexpectedly standout and fanastic. Lower price compared to competitors in bracket and is "value" in the high end IEMs.  Requires source/cable/tip rolling to improve on tone and technicalities, otherwise can come off as somewhat bright and lacking in bass quantity, and/or technically behind other good sets priced above it.

Canpur CP74E

• Smirk Audio: Punchy bass with some bass body bloat. Pleasant, euphonic vocal timbre with good note body. Decent treble minus the lower/mid-treble dip.
• Shuwa-T:  Retains all the techs of the 622b with a more tamed bass presentation, overall arguably more balanced sounding than the 622b  Bass transition to lower midrange may not work well for slower genres requiring a higher midbass shelf; less versatile
• Bad Guy Good Audio: Canpur’s CP74E steps in as the “just-under-flagship” sibling to the CP622B, packing 7 balanced armatures + 4 EST (11 drivers) and a neutral-warm tuning. The graph shows a tidy ~10 dB box ...

• Jaytiss: Very safe tuning, but safe is great.
• Smirk Audio: Lush and mid-bassy set with no obvious tuning issues. Technicalities could be better at this price range.

Unique Melody MEST Indigo

Nightjar Duality

• Jaytiss: Bass thunder, with impedance adapter fun and switches. The 11 is for Z.
• Smirk Audio: Massive yet controlled bass. Lush timbre and well-extended, non-pesky treble. Bassy mode may be too bassy for some. Mids can be a touch forward on balanced mode.
• Shuwa-T:  Pretty much a must have for bassheads, with surprising clarity in highs
• Head-Fi.org: 6 community members have rated the Nightjar Duality at an average of 4.0/5 on Head-Fi. Overall sentiment: Very Positive.

Kinera Loki

Empire Ears EVO

• Jays Audio: Great bass texture. BC driver actually works. Very well controlled but still impactful. Great resolution. Doesn't scale well because of spicy uppermids. Vocals often gets shouty on certain tracks,...
• Precogvision: An improvment over the LX SE's bass, but still lacking in the Odin's control. BC is no gimmick at least.

qdc Anole VX

• Gizaudio Axel: A highly detailed IEM.  Endgame-level detail.  BA bass and timbre.
• Precogvision: Very well-rounded, but sounds overly plasticky and artificial.
• Tim Tuned:  Unrivaled Resolution  Can be fatiguing
• Shuwa-T: Comment: Sounds like a DD iem but with the clarity and speed of BA; unrivalled clarity.  You'll hear more sounds than intended
• Nymz: Lovely tonality with incredible technicalities that scream details everywhere. Sinning only on female vocal position and BA timbre. Hits my HRTF like I like to hit my credit card.

Unique Melody MEST Jet Black

• Jaytiss: Safe, clean iem.
• Super* Review: Super* Review finds the $1,700 MEST Jet Black bright and exciting with tight sub-bass and standout, holographic imaging, but highly tip-dependent and sometimes sibilant/fatiguing. While the ceramic...

Empire Ears Odin

• Crin: A Legend X with the bass properly controlled and the resolution one step higher.
• Precogvision: High-clarity signature that invokes a sense of stateliness.
• Tim Tuned:  Well textured bass, good control, pleasing tones

Ice Lab Spectrumica

• Jaytiss: Kinda overly bassy, but good treble, and well done.
• Super* Review: Kind of what people expect from a 2000$ IEM. Very strong first impression effect. Mid-Range performance and quality of vocals not quite there where I want it to be.
• Head-Fi.org: One community member has rated the Ice Lab Spectrumica at an average of 4.0/5 on Head-Fi. Overall sentiment: Very Positive.

Softears RS10

• Gizaudio Axel: I prefer more bass.  Great tuning with forward vocals and excellent detail.  Unvented design, BA bass, and can be slightly shouty on some tracks.
• Crin: A little shouty and intense but very resolving and well-defined. A somewhat refined Moondrop S8.
• Jaytiss: Nice iem, clean clear out of the box
• Precogvision: A slightly more resolving S8 at the expense of added grittiness and more upper-midrange.
• Tim Tuned: Softears RS10 targets a Harman-leaning reference balance with a clean, studio-grade presentation: bass is tight and linear with modest mid-bass punch, prioritizing speed, texture, and...  BA timbre
• Head-Fi.org: 2 community members have rated the Softears RS10 at an average of 4.5/5 on Head-Fi. Overall sentiment: Outstanding.

Vision Ears EXT

• Precogvision: Tasteful W-shape tuning that delivers in the technical department. Mid-treble can be sharp, though.
• Nymz: Pleasant warm tonality with an agressive treble and techs to back it up. Treble will be too hot if you are extra sensitive. Fit is an issue.

Noble Kublai Khan

Penon Impact

• Nymz: Limp bass, but good mid-range and treble tuning. Techs felt underwhelming for its price, with extremely blunted transients.
• Head-Fi.org: 13 community members have rated the Penon Impact at an average of 4.6/5 on Head-Fi. Overall sentiment: Outstanding.

Eminent Ears Ruby

Fir Audio RN6

• Nymz: Good bass texture with nothing else remarkable... until I saw its price.
• Bad Guy Good Audio: Fir Audio RN6 brings a six-driver recipe and a limited-edition flair to the tour, dressed in satin black aluminum with a sapphire-glass faceplate and that signature grill exposing the Kinetic...  Bass texture and timbre is best in IEM game, overall excellent  Filters are too small cable qc is not matching price

Campfire Audio Trifecta

• Jaytiss: It's a tubed iem, very unique. Very hit or miss on music, love it or hate it.
• Head-Fi.org: 5 community members have rated the Campfire Audio Trifecta at an average of 4.8/5 on Head-Fi. Overall sentiment: Exceptional.

Hidition Violet

• Crin: Strong sub-bass presence, slightly cut-back upper mids. A fun IEM through and through.
• Precogvision: The best BA bass that I have heard, otherwise marred by poor imaging and slight congestion issues.

64 Audio U18T

• Precogvision: Bloated BA bass and overly compressed dynamic range. The least "64 Audio" sounding IEM that fails to bridge mainstream tuning and Hi-Fi.
• Super* Review: Positioned as a top-of-the-line “reference” set with 18 BAs and a ~ $3,000 tag, the 64 Audio U18t brings a brighter tilt than its siblings. With the M15 APEX module, treble gains presence...
• Web Search: The 64 Audio U18t is a high-end, 18-BA universal IEM that combines the company’s tia tubeless treble driver and apex pressure-relief modules, targeted at reference-grade monitoring and critical...

Softears Cerberus

• Gizaudio Axel:  Darkish treble.
• Crin: Lacking definition in the treble, otherwise a decently balanced tribrid IEM.
• Precogvision: Dissapointing lack of treble extension and very weak bass (literally sounds more BA than it does DD).
• Head-Fi.org: 3 community members have rated the SoftEars CERBERUS at an average of 4.7/5 on Head-Fi. Overall sentiment: Exceptional.
• Yifang:  One of the most tonally neutral, argubly the most reference & "correct" sounding to exist. Competent technicalities.  Doesn't necessarily round super engaging or fun. Bass and extension is lacking in quantity. Technicalities fall short compared to certain competition in the modern market.
• Kois Archive: Rating: S | Value: ⭐ | Gaming: 🎮🎮 | Comfort: 9  best chill relaxed set. godlike soundstage  dark treble presentation. could be boring.

Lime Ears Anima

• Precogvision: Vocals have an odd pinna rise. Basically like someone took the Moondrop Variations and made it sound weird.

Empire Ears Legend X SE

• Crin: A more upper-mid-forward variation of the original Legend X, which could come off as slightly more mid-recessed.
• Precogvision: Lacks control in the bass, but it's so fun. Excellent imaging performance that belies its tuning.

qdc Anole V14

• Crin: Rather bassy even in stock form; fun and engaging, though at the expense of sheer technical performance.
• Precogvision: Fixes Anole VX's bass texture and plastickyness, but comes with its own quirks in the metallic treble.
• Shuwa-T: Comment: Bass heavy for BA with no strange timbre.  Great detail retrieval and technicalities  Almost comes across as somewhat messy with that much clarity that it ruins the cohesiveness

Oriolus Monachaa

• Jaytiss: Poor Value, I can't recomend it.
• Smirk Audio: Very nice bass and decent treble. Midrange timbre and decay sound off. Technicalities are average for its price range. Cons: Poor techs/price, vocal timbre off.
• Head-Fi.org: 6 community members have rated the Oriolus Monachaa at an average of 4.5/5 on Head-Fi. Overall sentiment: Outstanding.

Noble Audio Ronin

• Precogvision: Lower midrange is overly thick and not enough treble extension to pull off this type of tuning. Like a scuffed Andro 2020.

Empire Ears LEGEND-X

• Crin: High resolution hybrid flawed only by lack of control in the bass regions.
• Precogvision: Bass lacks texture, but a fairly holographic, "grand" presentation that is unique for a V-shaped response.
• Bad Guy Good Audio:  Bass, details,sparkle  Bass (too much for some genre) mids

Fir Audio XE6

• Shuwa-T: Comment: Golden exterior costing more than jewelry.  Very commanding midbass presence  Recessed midrange overpowered by bass boost, just sounds tonally off

64 Audio U18S

• Precogvision: A worse U12t. Lacks U12t's dynamic range and layering chops.
• Head-Fi.org: 2 community members have rated the 64 Audio U18s at an average of 4.0/5 on Head-Fi. Overall sentiment: Very Positive.

Empire Ears Legend Evo

Moondrop Solis 2

• Gizaudio Axel: I prefer more bass.  Great bass quality, vocal clarity, and detail.
• Precogvision: Very mediocre sounding overall and build quality is reminiscent of a $20 IEM.

Dita Perpetua

• Shuwa-T: Comment: For acquired tastes, while your wallet gets acquired in the process.  The cable is more impressive than the IEM  Overall resolution, honestly pretty low resolution
• Head-Fi.org: 5 community members have rated the DITA Perpetua at an average of 4.6/5 on Head-Fi. Overall sentiment: Outstanding.

Vision Ears Elysium

• Crin: First decent implementation of Sonion's EST tweeters.
• Precogvision: The first "passable" implementation of the Sonion ESTs. Not particularly coherent, unfortunately.

64 Audio Fourte

• Precogvision: Tia Trio's older brother that takes things too far off the beaten path for tonality.
• Shuwa-T:  Smoothened sound compared to u12t and Trio  Tonality is very strange, even more wonky than Trio

Flipears Aurora

• Shuwa-T:  Bass hits with real subwoofer qualities, generally balanced sounding with no real faults  Extremely difficult to obtain

Final x Dita Shichiku.Kangen

• Precogvision: Dynamic and bites hard but poor treble extension and questionable tuning.

FiR Audio Neon 4

• Head-Fi.org: One community member has rated the FiR Audio Neon 4 at an average of 3.0/5 on Head-Fi. Overall sentiment: Mixed to Positive.

Noble Audio Shogun

• Fox Told Me So: Noble Shogun makes a bold first impression: bass—massive, dominant, and impossible to ignore. The overall tonality leans dark, with low frequencies taking center stage. Bass gain exceeds JM1’s...

Vision Ears VE8

• Crin: Extremely coherent signature with a pleasing tuning and high technicalities.
• Precogvision: The warm IEM of warm IEMs. Carried by its excellent midrange.

AAW Canary

• Crin: Poor implementation of the EST driver. Decent in tonality and timbre, but that's about it.

64 Audio Fourte Blanc

• Precogvision: Quite detailed, but lots of uncanny valley in the midrange (sounds like singers are singing into a cup) and treble is contentiously bright.

64 Audio tia Fourte

• Crin: Unique sound; high clarity and bass response with immensely wide staging, held back by a wonky tonality.
• Precogvision: Tia Trio's older brother that takes things too far off the beaten path for tonality.

Final Audio A8000

• Crin: Technically strong but going too far with the treble emphasis.
• Precogvision: Ear piercing upper-midrange and treble response. Decent technicalities, but a far cry from the Dunu Luna.
• Shuwa-T: Comment: Final's best IEM.  Massive soundstage backed by superb clarity, Japanese tuning style  Intense treble region

Audeze LCDi4

• Crin: Low distortion, high resolution and excellent clarity marred by poor tuning which destroys timbre.
• Precogvision: Top-tier imaging and layering, DSP is mandated for proper tonal balance.

Plussound Sonora

• Jaytiss: BRIGHT. So bright.
• Head-Fi.org: 2 community members have rated the Plussound Sonora at an average of 3.5/5 on Head-Fi. Overall sentiment: Generally Favorable.

Simphonio VR1

• Precogvision: Lack of air and mostly sounds like a generic single-DD that's been dampened.

Empire Ears Wraith

• Crin: A Zeus with almost nonexistent treble and clarity.
• Precogvision: This IEM's name about sums it up.

JH Audio Layla Aion

• Precogvision: Muddy with no upper-midrange or treble extension to speak of. You wouldn't know this IEM had 12BAs.
