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.

Our summary
Product Strengths
- Tremendous transparency, offering a wealth of microdynamics and spatial cues, critical in determining positioning and layering.
- Incredibly clear sound, yet wrapped in a warm, lush, and inviting overall picture.
- Highs are extended, detailed, and wonderfully resolved, easily able to summon the ethereal or holographic when called for.
- The soundstage is quite impressive—deep, wide, with very good headroom, and holographic when called to be so.
- The shell design is comfortable with a short nozzle, and light weight.
Product Considerations
- The treble is a little bit relaxed, and some songs may not cut through the way they need to.
- Amplifiers for this particular headphone are going to matter, and they are going to make a difference between several different amplifiers.
- The bass does not bring the rumble, nor the impact, nor does it reach to the stygian depths of the Holy-Bass-Head-Grail.
- Though the Odin provides for a comfortable fit, it can be uncomfortable for people who have really small ear holes, as the stem itself is quite wide.
- The 'Bifröst' faceplate design might be too flashy for some.
Comparisons (according to reviewers)
- Vs Empire Ears Zeus: The Odin smashes the Zeus all day, every day, for sound quality, with a better midrange and significantly nixed highs.
- Vs 64 Audio U12T: Odin is at least as good, if not better, in the mids and the bass, and has better punch and slam to the bass frequencies.
- Vs Empire Ears Legend X: The Odin is a much more balanced-tuned IEM.
- Vs 64 Audio Tia Forte: The Odin has a more agreeable frequency response.
- Vs Thieaudio Monarch: The Monarch has a really nice bass shelf, but the Odin has better technical performance and a better frequency response.
Takeaway: The Empire Ears Odin offers an easygoing listening experience and clear sound, and has tight bass response with a great midrange. It could be a great choice for those seeking a warm IEM with finesse.

Our summary
Product Strengths
- Incredibly clear and detailed sound, offering a transparent window into the music
- Well-defined, punchy, and high-quality bass response, with good impact and rumble, without being muddy
- Smooth and well-defined treble, avoiding sibilance or harshness, and retaining excellent resolution
- Broad and deep soundstage with excellent imaging, layering, and separation of instruments
- Visually striking and beautiful Bifrost faceplate design
Product Considerations
- The fit may be uncomfortable for users with smaller ears, as the stem is quite wide and the monitors themselves are fairly large
- Upper mid-range can be forward, and at times can be borderline shouty or fatiguing in some tracks
- Treble response, while detailed, might be a little relaxed for some, not cutting through as much as some other IEMs
- Some reviewers found the build quality of the resin shell to be just okay, not feeling particularly premium or durable relative to the price
Comparisons (according to reviewers)
- Vs. 64 Audio U12T: The Odin has better punch and slam in the bass, while the U12T has a more layered and separated sound with slightly more micro-details
- Vs. Empire Ears Legend X: The Odin is much more balanced and refined compared to the bass-heavy Legend X
- Vs. Fir M5: The M5 has a more forward and clearer treble response and wider soundstage, but the Odin's midrange is more forward and produces a more enjoyable vocal response
- Vs. Empire Ears Zeus: The Odin is smoother with more bass response and a better mid range
- Vs. Vision Ears Elysium: The Elysium brings an analog-like ease to the midrange, but is not a match for the Odin in detail and transient speed

Expand Details
Our summary
Product Strengths
- Delivers an explosive, amazing, and enjoyable sound
- Extraordinary bass that is thunderous when needed, but not bass-heavy, with amazing mids and trebles that do not overpower each other
- Excellent lateral width to its soundstage, top-tier layering, and a strong sense of center image
- Provides excellent vocal dynamics; whether intimate, epic, whispered or shouted, everything sounds natural with everything in its place
- Captures the almost over the top intensity of Odin, but also offers more weight, thickness, and a touch more realism
Product Considerations
- The Raven is a very large IEM, which may be uncomfortable for those with smaller ears
- The treble has a strong emphasis on lower-treble, leading to a distinctive, dry “chhh” on percussive hits, which can be fatiguing at louder volumes
- There are clear distinctions between its bass, midrange, and treble wherein it sounds like they are being handled by different driver types
- The Raven has a bass-centric tuning where the mid-bass is the most forward frequency
Comparisons (according to reviewers)
- Compared to Empire Ears Odin: The Raven's bone conduction driver gives it an edge in bass extension and in the general texture and balance of the bass
- Compared to Elysian Annihilator 2023: Has a wider soundstage, while the Annihilator sounds sharper, faster, and more detailed due to its thinner midrange and nearly linear treble response
- Compared to Empire Ears EVO: Sub-bass depth and extension is similar between the two, however the Raven has slightly more forwardness in the mid-bass
- Compared to Noble Viking Ragnar: The Raven captures its greater weight and body, but opts for a little more bass, while Ragnar opts for more treble
Takeaway: The Raven provides an engaging and immersive experience that will allow one to fully enjoy their music. It will put you in your own little world, where nothing gets out or in.
