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
- 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
Takeaway: The Empire Ears Odin is a technically impressive IEM with a smooth, clear sound, detailed bass and a striking design. If one is seeking a high-end listening experience where details are clearly displayed in an immersive 3D stage, these could be a great match.

Brand highlights
Taking a step back to look at reviewers' thoughts of the brand's entire lineup—not just this product—what stands out most is the following:
- Empire Ears IEMs often employ a multi-driver hybrid design, combining dynamic drivers for bass, balanced armatures for mids and highs, and sometimes electrostatic drivers for enhanced treble, all managed by a complex crossover network.
- The brand's proprietary Weapon IX or W9+ dynamic drivers, known for their innovative bass-reflex system, consistently deliver a powerful, impactful, and well-textured bass response.
- They offer a high degree of customization for their custom IEMs, including a wide variety of faceplate materials, shell colors, and logo options, allowing customers to create a personalized aesthetic design.

Product Strengths
- Build quality is sensational, handmade in Taiwan, and has thousands of man hours put into it
- The kit has detachable clickable connections, and high-quality pure copper cables
- Comes with accessories such as replacement parts for the earbuds, and adapters (3.5, 4.4 for balance, and 2.5 balance)
- Accessories are beautifully made with wood and good hinges
- The product features a two-way speaker system inside an earbud
Product Considerations
- It demands good, abundant power to be driven, due to its specifications of 93dB sensitivity, and 182 Ohms
- Needs to be burned-in (driven) for no less than 200 hours, and most possibly 300 hours
- The stock cable has tiny connectors which make it very difficult to connect any wire beyond 26-28awg
- The outer packaging box seems to be a reformed cardboard box, which is huge and white, and may not be durable in the long run
- The proprietary MMCX-designed connectors means the cable’s tiny connectors make it very difficult to connect any wire beyond 26-28awg and perhaps a very thin 2 or 4 wire at best
Comparisons (according to reviewers)
- The oBravo RA-C-CU excels versus the Vision Ears EVE2020 across every parameter, though there is a warmth across the EVE’s midrange via its dynamic driver, that moves it to, at least, competitive with the RA-C-CU and its Neodymium Dynamic Driver
- There were no aspects between the Vision Ears ELYSIUM and the oBravo RA-C-CU where the oBravo did not excel
- The oBravo RA-C-CU extends a competitive advantage across all relevant parameters from bass extension to treble extension to transparency to a coherency that holds together through the most complex and dynamic passages to a more expansive soundstage, compared to the oBravo EAMT-2C
Takeaway: The Ra-c-cu (21.5) is a very well-made earbud that gives a sensational listening experience like high-end speakers in one's ears. If one wants to treat oneself with serious earbuds where money is not a problem, this is the way to go.

Our take on the brand
Our summary
Product Strengths
- Considered by many as having the best sound achievable in an in-ear headphone, making it an exceptional audio experience
- The sound signature is mostly balanced with tasteful coloration, where the treble imparts a particular element that is potentially preferable
- The midrange is extremely well done
- Features unique SLAM subwoofer, woofer, midwoofer, mid tweeter, tweeter and EST technologies
- Built with Grade 5 titanium, providing sturdiness and high quality
Product Considerations
- Treble performance can be hit or miss depending on the listener's anatomy and HRTF
- Requires more power than typical IEMs, potentially draining the battery of portable audio players
- Shells are on the larger side
- The included cable is nice, but the chin cinch tends to slide down
Comparisons (according to reviewers)
- Compared to the Hi-Senior Megafest and Dusk Default DSP, the Storm is an editorialized or enhanced version of those IEMs, particularly regarding bass and mids
- Compared to the 64 Audio U6T, it has similar balance with similar tasteful colorations, but Storm's bass is more punchy and the upper treble is more to the reviewer's preference
- Compared to the Empire Ears Odin, the Storm is preferred because the Odin is not as versatile, and the Storm sounds more detailed
- Compared to the Empire Ears Raven, the Storm is more normal in a good way because the Raven has massive bass and a strange lower midrange resonance feature
- Resolution, stage and tonality are better on the Storm compared to Grand Maestro
Takeaway: The Storm is a high-end IEM with exceptional sound quality and great build, even if pricey. It could be worth buying for those who want the best possible audio experience and appreciate a balanced sound with unique features.

Our take on the brand
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 take on the brand
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.
