What reviewers think

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

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.

  • Vs Noble Viking Ragnar: The Viking Ragnar emphasizes treble more, with a stronger sense of air and definition, while the Phönix is more relaxed, the Viking Ragnar is for analytical listening, while the Phönix is for a more relaxed experience
  • Vs Empire Ears Odin: The Odin has more bass texture, resolution, and deeper extension, the Phönix has fuller and richer mids
  • Vs Empire Ears Legend Evo: The Legend Evo is bassier and more exciting, while the Phönix places bass more in line with the rest of the signature and has a wider stage
  • Vs 64 Audio Noir: The Noir sounds grander and bigger, with stronger bass, while the Phönix has a more balanced signature and better-controlled bass
  • Vs Vision Ears Erlkönig: The Erlkönig's bass is softer, and the Phönix pushes more volume in the upper-mid and treble sections, the Phönix gives more glow and better extension up top
  • Vs Vision Ears EXT: The EXT has more sub-bass, with better texture, control, and resolution, the Phönix has fuller and richer mids, while the EXT has lighter vocals

Check Amazon
Expand Details

Product Strengths

  • Excellent technical performance and detail retrieval, considered several cuts above other IEMs
  • Outstanding imaging performance, with precise soundstage and instrument separation
  • The bass response is a highlight, delivering a punchy sub-bass with texture and articulation
  • Offers a warmer tonal balance that is easy to get into with a mostly 'neutral' sound
  • Bone conduction enhances low-frequency extension, reverb, and detail

Product Considerations

  • Large chassis that may be uncomfortable for some users, particularly those with smaller ears
  • The subdued treble range may not provide enough energy and sparkle for some listeners
  • Stock cable is lackluster in terms of usability due to its plasticky feel, rigidity, and microphonic feedback
  • Driver flex (a harmless crinkling sound upon insertion) is present

Comparisons (according to reviewers)

  • Legend Evo delivers a stronger bass impact, depth, and extension than the Legend X
  • Legend Evo produces better constructed highs than the Legend X
  • Legend Evo shows better clarity than the Legend X, and has more detail
  • The Legend X can sound veiled concerning the Legend Evo
  • The Legend Evo feels a touch smoother than the Empire Ears ODIN

Takeaway: The Legend Evo is a top-tier IEM with innovative bone conduction technology that creates a unique and immersive listening experience with enhanced bass. It is a great option for those seeking flagship-level performance with a warm, bass-focused sound signature.

Campfire Audio
Astrolith
2199
/
Released
2024
The latest from the acoustics team at Campfire Audio, Astrolith represents the tip-of-the-spear for IEMs using a pure planar magnetic architecture. Further expanding on Campfire's lineage of planar earphones, Astrolith incorporates two new drivers wrapped in our PPR and AAOI tuning elements. Combining the inherent advantages of planar magnetic drivers with decades of acoustic engineering experiences brings about an incredible new horizon in the realm of planar magnetic IEMs.
Check Amazon
Campfire Audio is a hifi headphone brand known for their Tuned Acoustic Expansion Chamber (TAEC) for balanced armatures and Solid Body Design that mounts drivers into a single 3D-printed "engine block" to improve tuning and reliability. The brand has pioneered several unique approaches, such as crossoverless dual-planar architecture, beryllium-PVD dynamic diaphragms, and 3D-printed ceramic acoustic structures. Their Andromeda model long held a reputation as a benchmark reference for hifi IEM performance.
Expand Details

Our Summary

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
/
Released
2023
SVANAR — HiFiMAN's Flagship Single Dynamic Driver IEM with Over-Ear Detail.
Check Amazon
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.
Expand Details

Our Summary

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.

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.
