Welcome

In-ear monitors seal in the ear canal, so they need far less power than full-size headphones and block the room around you. The interesting engineering is in the drivers: dynamic for bass, balanced armature for detail, electrostatic tweeters in the expensive ones, and hybrids that stack all three. These are the sets with the most reviewer coverage. The cheaper Chinese brands here are reviewed as seriously as the flagships, and often come out well.

Reviews
NOVA is a 1DD+4BA in-ear headphone with 3-way crossover composite structure. Compared with HEXA, the original design intention is to further improve the high-frequency performance while maintaining a reasonable and efficient configuration, and also strive to bring users a mature earphone with a hybrid 3-way crossover structure at a reasonable price.
TRUTHEAR is a Chinese maker of in-ear monitors, founded in 2022. The Shenzhen company based the tuning goals of some models on HRTF characteristics measured with a BK5128 head and torso simulator, and two were tuned in collaboration with Crinacle. Most models have DLP 3D printed cavities, and the range covers single dynamic driver sets, dual dynamic designs and hybrids that mix a dynamic driver with balanced armatures. The Nova pairs one dynamic driver with four balanced armatures in a three-way crossover, and it is on our Best IEMs list.

What reviewers think

Product Strengths

  • Sound signature is likely to be palatable for a wide range of people at its price point.
  • Good emphasis in the upper midrange, decent timbre, good resolution, the upper midrange is upfront with the vocals, nice details, and it works well with a smooth treble.
  • Very smooth treble and the absence of sibilance.
  • Good dynamic bass that's nicely textured and has a decent rumble.
  • Imaging is accurate.

Product Considerations

  • The Truth Ear Nova does not sound better or more balanced than the Hexa, since the reviewer prefers a more balanced sound signature.
  • Nova is not a thick-sounding IEM, it's quite thin.
  • The midrange is chiefly defined by a cavernous suckout in the low-midrange.
  • Soundstage is a little narrower than preferred.
  • Shell size may be slightly large for smaller ears.

Comparisons (according to reviewers)

  • Vs. Moondrop Variations: Nova is significantly cheaper and close enough in performance that one should save money and go for Nova.
  • Vs. Truthear Hexa: Nova easily has a smoother treble presentation, has more dynamic bass, and is more ergonomic, but Hexa has one of the best midranges in this price tier.
  • Vs. Truthear Zero: RED: Zero: RED beats Nova almost across the board in tuning and simply sounds more normal.

Takeaway: The Truth Ear Nova is commendable for achieving its tuning at its price point, especially for those looking for a V-shaped presentation or Harman-esque kind of sound signature. If the Harman IE target is to one's liking, Nova is probably as safe a choice as any of the other Harman options out there.

Reviews
SVANAR — HiFiMAN's Flagship Single Dynamic Driver IEM with Over-Ear Detail.
HIFIMAN is the reason planar magnetic headphones are no longer exotic. Started by Dr. Fang Bian in 2005, the Chinese company builds planars with nanometer-thin diaphragms and open "Stealth Magnet" arrays shaped so sound passes through with less turbulence and distortion, and it also makes electrostatic headphones at lower prices than the category usually asks. The tuning varies from warm to neutral across the range, so it pays to choose a model by sound, and the Sundara and the Arya are both on our Best Open-Back Headphones list.
Expand Details

What reviewers think

Product Strengths

  • Captures the sound of the original Svanar, with a balanced tuning emphasizing bass and treble while maintaining the mids
  • Incredible imaging performance, offering a wide, well-rounded, three-dimensional soundstage with excellent positioning and separation—highly competitive, even compared to non-TWS IEMs under $1000
  • Has an R2R DAC which permits unreachable technical performance
  • Very light and comfortable
  • Excellent connectivity and usability

Product Considerations

  • LDAC connectivity issues with invasive intermittence and noise cutting
  • ANC and Transparency mode aren’t very useful and lack dynamic, delivering leaner dynamic, less musicality
  • Plastic build might not be most durable if dropped
  • High-frequencies are quite sensible to the source, making it one of the least forgiving TWS
  • Hiss is also present

Comparisons (according to reviewers)

  • The Svanar Wireless is punchier, with better bass detail and imaging, and a wider soundstage, while the Final ZE8000 has a warmer, more neutral sound
  • The Svanar Wireless has stronger imaging performance, a wider soundstage, and a better balance between separation and cohesion
  • The Svanar Wireless is superior in technicalities and tonal balance, as well as timbre and tone naturalness, and ultimately musicality
  • The Svanar Wireless' soundstage is taller and wider but not as deep, since clarity isn’t as sharp and clean, silence being more "noisy"
  • The Svanar Wireless has better sound and performs better technically
  • The Sony TWS has bloated bass that overwhelms everything else; in comparison, the soundstage and treble performance of the Svanar Wireless is miles ahead, presenting a much more detailed, natural, and sophisticated kind of sound

Takeaway: The Svanar Wireless sounds impressive for wireless earbuds, and it has great connectivity and features. For those seeking high-end wireless sound, these are worth considering.

Kinera is a Chinese maker of in-ear monitors, founded by Aaron Yu, and each of its product lines starts from a mythological or artistic theme, often from Norse mythology. Many models have hand-painted faceplates, so no two pairs look quite alike. The IEMs mix dynamic, balanced armature and electrostatic drivers in hybrid layouts, and Kinera develops its own Pulse dynamic drivers. The Imperial Baldr 2.0 combines all three driver types with detachable cables, and the URD is on our Best IEMs list.

Reviews
A quad driver hybrid UIEM featuring ground-breaking patented technologies originally developed for our flagship products in order to bring a wider audience closer to their music.
64 Audio is an American maker of in-ear monitors, started by sound engineer Vitaliy Belonozhko, who saw the advantages of IEMs over stage floor wedges. Its tia drivers are open balanced armatures in custom acoustic chambers with no tubes or dampers. LID circuitry keeps the tuning consistent whatever the output impedance of the source device. Owners can swap Apex modules, which vent pressure from the ear canal to reduce listening fatigue and subtly change the bass. The U4s and Fourté are on our Best IEMs list.

What reviewers think

Product Strengths

  • Versatile sound signature, going from bassy to neutral with the use of included tuning modules
  • Excellent bass response with a dynamic driver, providing strong texture, deep extension, and impact
  • Very good treble extension, air, and sparkle for detail retrieval without harshness
  • Expertly captures the 64 Audio character of balancing pro audio sensibilities and a more audiophile-friendly sound
  • Comfortable and durable design, with a lightweight anodized aluminum shell and well-thought-out accessories

Product Considerations

  • Imaging and instrument separation are decent, but not standout for the price range
  • Mid-range may sound a bit thin to some, with a more relaxed upper mid-range that results in vocals being a little bit on the husky side
  • The nozzle doesn’t have lip holder and is a bit problematic
  • Isolation isn't exceptional due to the apex module

Comparisons (according to reviewers)

  • Vs 64 Audio Neo: U4S is preferred due to the U4S being the cheaper IEM
  • Vs Thieaudio Monarch MkII: The Monarch is comparatively lean sounding
  • Vs 64 Audio U6T: U6T is a little more neutral overall with a stronger technicality, but the U4S injects a little more fun into the sound
  • Vs Campfire Audio Andromeda Emerald Sea: The U4S offers a more natural mid-range presentation
  • Vs 64 Audio Nio: The U4s effectively undercuts the Nio by a third of the price with comparable sound quality
  • Vs Custom Art Fibae 5: If you want technicalities and details, Fibae 5 is superior, if you want a very capable yet slightly musical and mainstream IEM, opt for the U4s

Takeaway:

The 64 Audio U4s is a well-rounded IEM that offers a fun and engaging sound signature with the ability to customize the bass response. With its comfortable fit and excellent build quality, it's a great option for those looking for a versatile and enjoyable listening experience.

What reviewers think

Product Strengths

  • Very comfortable and lightweight design thanks to the use of aluminum in the chassis
  • Impressive soundstage, imaging, and layering, creating an open and expansive experience
  • Delivers excellent detail retrieval and internal resolution, surfacing intricate vocal and instrument tones
  • The Tia system allows sound to travel to the ear more naturally, resulting in an expansive soundstage and smooth frequency response
  • All-around great sound complements just about every genre

Product Considerations:

  • Stock tonality is often described as poor or quirky, with a V-shaped tuning and recessed upper mid-range
  • The stock cable is considered tangle-prone, with significant cable noise
  • Significant peaks in the lower treble can introduce glare, sibilance, and tinniness
  • Some reviewers feel that the overall tuning diminishes the emotional effect of music and negatively impacts instrument timbre
  • Some reviews indicate it's not as linear for its tonality and more classically audiophile, which may disappoint some

Comparisons (according to reviewers)

  • Vs. Empire Ears Legend X: The Fourté is far more balanced overall for its tonality
  • Vs. 64 Audio Trio: The Fourté does much better at space and stage, detail retrieval is a little bit better in the mid-range
  • Vs. U12T: The Fourté does better as far as its technical aspects go but not as linear for its tonality, it gives you something that is a different flavor from the ones that might be used to
  • Vs. ODIN: The ODIN is slightly more organic and clear, while the listening experience with the Fourté is more intimate

Takeaway: The Fourté IEM is a comfortable and technically proficient IEM with excellent soundstage and detail. With EQ, it delivers the technical performance that is desired from a high-end set of headphones.

Reviews
Electrostatic driver + Dynamic driver + Balanced armature hybrid drivers, with the excellent physical filter structure manufactured by 3d printing and the frequency division circuit, shows a perfect harmonious timbre.
Moondrop made the inexpensive in-ear monitor worth taking seriously. The Chinese company, founded in Chengdu in 2015, tunes to measured targets, the Harman curve or its own in-house target, using its own Klippel laboratory, and sells that tuning at prices that start around $20. The range runs from single dynamic drivers to tribrid designs with planar drivers in one shell, and on to full-size planar headphones such as the Para 2 and Cosmo. Its packaging and artwork often draw on anime.
Expand Details

What reviewers think

Product Strengths

  • Excellent bass response, especially in the sub-bass frequencies, providing a clean and distinct bass experience.
  • Well-tuned treble response with good extension, creating a smooth and enjoyable high-frequency experience.
  • Very good detail retrieval for its price point, considered one of the most resolving sets in its price range.
  • Cohesive sound signature with the tribrid driver system working harmoniously, providing a balanced listening experience.
  • Solid build quality with a unique and appealing design using 3D printed resin and a stainless steel faceplate.

Product Considerations

  • Midrange can be forward and shouty, especially in louder environments, potentially causing fatigue for some listeners.
  • Lower midrange can lean on the thinner side, making notes sound crisp, but potentially anemic for some.
  • Soundstage is good, but not the widest, with some cheaper IEMs offering a wider soundstage experience.
  • Fit can be an issue for those with smaller ears due to the larger size.
  • The lack of sizzle in the upper midrange to highs makes the Variations slightly dull for some listeners.

Comparisons (according to reviewers)

  • Vs. Moondrop Blessing 2/Dusk: Considered an upgrade, offering better bass texture and treble extension.
  • Vs. Dunu SA6: More aggressive, while the SA6 offers a smoother, more laid-back presentation.
  • Vs. Shure EJ07M: More technical with better detail retrieval, while the EJ07M has a smoother presentation.
  • Vs. ThieAudio Monarch/Clairvoyance: Considered on par or better in technicalities.
  • Vs. Sennheiser IE900: The IE900 has better bass response.

Takeaway: The Moondrop Variations are a solid choice for those seeking a well-built IEM with excellent bass response and a smooth, extended treble. Its detailed sound and unique design make it a worthwhile consideration for many listeners.

Reviews
A8000 is final's flagship model that realizes transparent sound for the uplift that can be gained by listening to music. Development of the A8000 began with reconstruction of physical measurement and subjective evaluation methodologies. Under the subjective evaluation methodology established at the time of D8000's development, the E Series achieved sound quality highly evaluated by many people and became a best seller. With the A8000, a new evaluation index has been incorporated into that subjective evaluation methodology.
final is a Japanese earphone and headphone maker based in Kawasaki, where it develops and produces its own drivers and assembles its high-end models in its own factory. It also builds its own jigs and machines. The range spans planar magnetic headphones to entry-level earphones, and many models are voiced for a purpose, such as the VR2000 and VR3000 for gaming. Reviewers praise its earphones built on one full-range balanced armature driver, and their spacious soundstages. The UX3000 is a wireless noise-canceling headphone with a driver designed for the stresses of active noise cancellation.

What reviewers think

Product Strengths

  • Excellent clarity and works well with different genres of music, sounding upbeat and uncolored.
  • A lot of micro-detail with great control over sudden volume changes, with terrific response speed, while keeping articulation smooth.
  • Superior bass with the linearity of the bass, how tight, lean, and linear the bass sounds compared to other models.
  • Astonishing in all kinds of ways, giving detail and a sense of presence.

Product Considerations

  • Ergonomics aren’t quite as amazing as they look because the shell is on the larger side, and the nozzle is quite short.
  • The shells pick up scratches and scuffs fairly easily.
  • They were a little bit tiring to listen to in the upper ranges, in some of the tracks it just sounded like the music was getting slightly swamped with just too much treble information.
  • Very bright.

Comparisons (according to reviewers)

  • Vs Sennheiser IE 800: Sennheiser is a very distant second to the A8000 in every department, the Sennheiser IE 800 sounded thin and harsh.
  • Vs JH Audio Roxans: Technical performance was not as good as the technical performance of the JH Audio, by which the reviewer meant there was clearer instrumentation and clearer vocals on the JH Audios, however, there was just something so good about the bass and the vocals.
  • Vs DUNU Luna: More transparent and spacious in sound and a league ahead in picking out brilliant treble detail, while maintaining excellent control of the bass in comparison to DUNU Luna.
  • Vs Final B1: Some similarities with the B1, mainly in how the mids are rendered, but with a much faster response speed and a more refreshing treble tuning.
  • Vs HIFIMAN RE2000 Silvers: The sound seemed just slightly cleaner in the mids, so the tracks were easier to follow and just slightly less fatiguing with HIFIMAN RE2000 Silvers.

Takeaway: The Final Audio A8000 is worth buying for the great sound quality, the attention to detail that went into making it, and the fact it can work with different kinds of music. It has amazing details and is made well, so one should be happy with it.
