What reviewers think

Bloggers and YouTubers have tried this product—so we've summarized their strongest opinions below. Links to full reviews follow.

Product Strengths

  • Smooth, natural, and easy to listen to sound signature that is not fatiguing
  • Impressive and beautiful design, with unique 3D faceplate and premium feel
  • Good build quality and comfortable ergonomic fit for most ears
  • High-quality modular cable with interchangeable plugs (3.5mm, 2.5mm, 4.4mm)
  • Full-bodied vocals and a versatile sound that works well with various genres

Product Considerations

  • Can be considered large and thick, protruding from the ears
  • Bass can lack definition, separation, and impact for some listeners
  • Stock cable may not unleash the full potential of the IEMs, and an upgraded cable is recommended by some reviewers
  • Midrange separation could be better for some users

Comparisons (according to reviewers)

  • Vs. the FiiO FH7: The URD is less aggressive, more charming, and has a wider soundstage, the FH7 has faster, more controlled bass but can be fatiguing
  • Vs. the DITA Audio Twins Fealty: The URD prioritizes weight, soft tonal balance, and timbre density, the Fealty emphasizes amplified resolution and detailed texture

Takeaway: The Kinera URD is a beautiful and comfortable IEM that offers a smooth and natural sound, making it a great choice for long listening sessions across many music genres. It stands out with its design, accessories, and non-fatiguing sound.

What are hifi reviews useful for? (1) Identifying products you should demo in person at a dealer. (2) Learning which products reviewers unanimously praise as the best they've heard (this means they probably are legitimately great). (3) Identifying a product's attributes that satisfy your idiosyncratic needs and tastes. Beyond that, we often discount what reviewers say because they heap praise on most products—and are often apprehensive about publishing strong criticism or comparisons between products. Further, they seldom have more than a few products on-hand, often relying on their memories to compare past products. Always listen for yourself.

Product Strengths

  • Absolutely gorgeous design, made of real wood with meticulous craftsmanship
  • Excellent selection of included tips, ensuring a good fit for most users
  • Spacious soundstage with good depth and well-defined spatial imaging
  • Good quality bass with good texture and impact
  • Clean, smooth, detailed treble with excellent extension and energy

Product Considerations

  • Tips can come off easily due to the lack of a lip on the IEM, requiring caution when removing from ears
  • Bass quantity is light and recessed, not ideal for bass heads
  • Midrange, especially vocals, is somewhat pushed back due to the forward treble
  • Treble response can be piercing and harsh, distorting some frequencies for some listeners
  • Included cable is decent but not the best, with some memory retention

Comparisons (according to reviewers)

  • Compared to the Campfire Audio Solaris 2020, the Baldr 2.0 offers a more in-your-face presentation of detail compared to the Solaris 2020's smoother presentation
  • The Baldr 2.0 is a step up in terms of treble presentation compared to the Fearless Audio Roland
  • Compared to the original Baldr, the Baldr 2.0 has an extended bass response and improved soundstage and imaging, but highs may not be as smooth

Takeaway: The Kinera Imperial Baldr 2.0 is a beautiful IEM with a unique sound signature that audiophiles who appreciate detailed treble and a spacious soundstage will enjoy. These could be a good choice for those who like great sound and a fantastic look.

  • Cable build could be better, as it feels a bit flimsy
  • Polished version is prone to scratches and fingerprints

Comparisons (according to reviewers)

  • Vs Viking Ragnar: The ThorKing is cheaper with slightly less performance, but it is a little less fatiguing in the treble range

Takeaway: The Kinera ThorKing is a uniquely designed IEM that offers detailed sound and a comfortable fit. Its technical performance is on par with its peers, making it worth checking out.

13
Reviews

Check Amazon
Expand Details

Product Strengths

  • Impressive technical performance, clarity, detail retrieval, and resolution due to its planar magnetic drivers.
  • Features a new, comfortable, and ergonomic shell design that's also lightweight and durable.
  • Includes two upgraded Time Stream Metal cables, providing both 3.5mm and 4.4mm terminations.
  • Delivers a strong, extended bass response, with texture and speed, plus a nimble, airy top-end.
  • Exhibits a spacious, wide, and holographic soundstage with good imaging and instrument separation.

Product Considerations

  • Lower sensitivity might require a dedicated DAP or amplifier for optimal performance, and can sound anemic when paired with just a phone.
  • Can be sensitive to source pairings, warmer DACs might wash out the mids and some pairings may bring out sibilance.
  • Stock tips might not provide the best seal for everyone, and the stock tip selection is poor.
  • Silicone eartips can make the treble sound harsh.
  • The mirror-finished stainless steel faceplate is prone to fingerprints and smudges.

Comparisons (according to reviewers)

  • Vs. Campfire Audio Bonneville: Astrolith has superior mids, clarity, detail and transparency, and better treble extension, articulation, and overall resolution.
  • Vs 64 Audio Volür: Astrolith offers bigger bass and a more exciting presentation, as well as faster and more resolving sound, but Volür is more accurate overall.
  • Vs. Oriolus Monachaa: Astrolith has a faster and more controlled bass with better texture, a more natural and realistic midrange with a fabulous timbre.
  • Vs. Elysian Acoustic Labs Annihilator: Astrolith delivers a more robust and organic mid-range with realistic and natural timbre and more defined lower mids.

Takeaway: The Astrolith is a technically impressive IEM with a comfortable design that delivers a powerful and detailed sound. It could be a great pick for listeners who want high-end sound that can play all kinds of music well.

HIFIMAN
Svanar
1999
1999
/
13
Reviews
HIFIMAN is a hifi brand known for its planar magnetic headphones that use extremely thin diaphragms and acoustically transparent "Stealth Magnets" to reduce sound distortion. The company pioneered high-resolution portable audio players and creates electrostatic headphones that bring high-end sound quality to more accessible price points, as well as widely renowned flagship models such as the Susvara.
Check Amazon
Expand Details

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.

  • Soundstage depth, imaging, and detail retrieval are only average, limiting its presentation

Comparisons (according to reviewers)

  • Vs Kinera Imperial Nanna: The Skuld falls perfectly between more budget-friendly models and higher-end selection

Takeaway: The Kinera Imperial Skuld is easy to listen to and enjoy. It has good instrument separation and layering, so all elements can be clearly heard.

Expand Details

Our Summary

Product Strengths

  • Offers excellent midrange resolution, highlighting subtle details in instruments

  • The shell is larger than average for a universal IEM, which may cause fit issues for some
  • Stock ear tips are just okay
  • Bass resolution could be better
  • Does not have an integrated microphone, so a standalone mic is needed to take calls

Comparisons (according to reviewers)

  • Vs. Monarch MKII: The MKIII has increased richness in its midrange and an upper treble exaggeration, offering a slightly U-shaped signature compared to the MkII's balanced profile
  • Vs. Symphonium Helios: MkIII's midbass body contrasts Helios' dipped lower mids, MkIII has better overall resolution, but a more exaggerated treble
  • Vs. 64 Audio U4s: The MkIII is better tuned compared to the U4s, with the U4s having a thicker midrange and weightier timbre
  • Vs. MOONDROP x Crinacle DUSK: The THIEAUDIO have a more detailed treble range
  • Vs. MOONDROP Blessing 3: The THIEAUDIO have a more elevated bass range
  • Vs. TRUTHEAR x Crinacle ZERO: RED: The THIEAUDIO do a better job blocking out external noise and leak less audio

Sennheiser
IE 600
899
/
Released
2022
Simply beautiful sound, and the lengths Sennheiser will go to achieve it — that is the story of the IE 600. These in-ear devices not only reproduce the detail and emotion of a recording, they transcend it. Because each earphone is a masterpiece. From the hand-finished amorphous metal housing to high-end audio components developed and made by Sennheiser, everything is manufactured to the strictest tolerances.
Check Amazon
Sennheiser pioneered the world's first open-back headphones with the HD 414 in 1968, which became the bestselling full-size headphone of all time, and later developed the HD 25, evolving from 1980s broadcast use to become the industry standard in DJ booths worldwide. The brand is known for unique engineering approaches, such as integrating high-voltage amplifiers directly into earcups with Carrara marble chassis in the HE 1, developing proprietary ring-radiator transducers and absorber technology to eliminate resonances, and creating the long-running MD 421 microphone that has remained in production since 1960.
Expand Details

Our Summary

Product Strengths

  • Agreeable, natural sonic signature
  • Sounds very good, feels tough, and comes with most of the accessories needed
  • Precision-milled housings follow the company’s IE 900, IE 200, and IE 300 models, shape wise, and therefore comfort wise
  • A well-engineered product that sounds excellent
  • Measured performance closely aligns with a headphone preference curve, so it sounds excellent

Product Considerations

  • Basic silicone eartips that don’t fit everyone
  • The MMCX connector is an atypical version that will not work with most other cables
  • The texture of the AMLOY-ZR01 finish is not everyone's favorite to wear
  • Treble is a bit subdued with cymbals resolving reasonably well, but way behind the IE 900
  • Stock tips that come with Sennheiser's earphones are poorly designed; the silicone lacks rigidity to the point of which it more often than not collapses against the ear when one inserts the IEMs, thus making a proper seal very difficult to achieve

Comparisons (according to reviewers)

  • Vs IE 900: The easier-to-drive IE 900 have a tighter, less thumpy low end and a leaner midrange, which results in better separation between the two, and also in better midrange resolution and clarity
  • Vs IE 900: The IE 900 also have a much superior (perceived) treble extension and resolution, and a much wider soundstage
  • Vs Final E5000: The final E5000 offer fuller voices, more bass, but less treble than the IE 600, and a narrower stage
  • Vs Meze ADVAR: The ADVAR's sound is taller than the IE 600, the latter has more width, and imaging is tight and well-produced in both IEMs, with the IE 600 edging out the ADVAR by the slightest of margins

Takeaway: The IE 600 is a great set of earphones that will appeal to listeners owing to their punchy tonality and is pretty much unparalleled in their class. With the IE 600, listeners get undistorted audio and great isolation, and durable materials that will always sound good.

Our take on the brand

FiiO stands out for integrating unique features into portable audio devices, such as their BTR7 DAC/amplifier with its screen and wireless charging, and their KB3 mechanical keyboard with a built-in DAC/amp. The brand caters to audiophiles seeking personalization through products like their pioneering X7 music player with interchangeable amp modules and their compact R7 desktop system that combines streaming, DAC, and headphone amplification capabilities.
