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
- Bass guitar, drums, and male vocals are emphasized due to the bone conduction driver
- Mids are clean and accurate
- Treble is less fatiguing compared to the MEST
- Dynamic presentation of music with energy and soul
- Good level of detail
Product Considerations
- Elevated mid-treble/lower-treble can take away from the cleanliness
- A drop in energy in the upper-treble region means it lacks ultra-high extension
- Bass definition might not be the MEXT's strong suit
- Bigger than other IEMs
- Resolution is average
Comparisons (according to reviewers)
- Vs 64 Audio Duo: The MEXT is more musical with a thicker sound and slightly bassy, while the Duo is more balanced with better clarity and imaging
- Vs MEST: The MEXT has less clarity, but better low frequency performance
Takeaway: The UM MEXT is a great choice for those who want a musical sound with boosted bass and enjoy the unique sensation of bone conduction. It’s a fun, energetic IEM that brings life to music.
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
- Natural, true-to-life tonality with a little bit of extra treble emphasis
- Detail retrieval and resolution is very good
- Soundstage is very good for an IEM, going a little bit beyond the ears and having a good sense of depth
- Imaging of sounds is fantastic
- The bass has a nice sense of body to it
Product Considerations
- Bass extension isn't massive
- Build quality is not as polished as expected, with visible glue lines
- The design of the earpieces has come in for some criticism from early adopters, mainly because the shipping faceplates look nothing like Unique Melody's product marketing pictures
Comparisons (according to reviewers)
- Vs. Sennheiser IE900: The tonal balance was better on the Unique Melody, the bass extension was better on the IE900
- Vs. Vision Ears Elysium: If one finds the Unique Melody too full and heavy sounding, the Elysium could also be a really good IEM to check out, even though the Unique Melody outperforms it technically
Takeaway: The Unique Melody is a fantastic sounding unit with a very smooth and clean sound that's still detailed and articulate. It offers clear benefits and an amazing listening experience.

They also created early planar magnetic IEMs and popularized quadbrid driver configurations that combine dynamic, balanced armature, electrostatic, and bone conduction drivers.
Expand Details
Product Strengths
- Impressive midrange imaging and a nice vocal presence
- Small form factor for a 12-driver IEM
- Lively affair with a slight v-shaped tuning favoring snappy lows and sparkling highs
Product Considerations
- The unboxing experience is similar to the Mason V3+, but at its price point, it could be more impressive compared to the competition
- The silicone tips are more porous and can shape the sound much more to the bright side, also causing a loss of bass response
- The universal version will not give the same level of passive isolation as the custom version
Comparisons (according to reviewers)
- More of a fun signature with a lot more bass/treble contrast and slightly less reference-oriented than the Mason V3+
- A contrasting presentation to the Mason V3+, the Mentor V3+ being a lively affair, whereas the Mason V3+ is thicker and more planted sounding
- The shell seems a bit tidier and more compact
- The dual-tone cable is a bigger cable than the original Dual Tone
Takeaway: The Unique Melody Mentor V3+ is an excellent monitor, with an exciting high-energy, and highly resolving performance. Its new carbon fiber shell and improved internal components make it a worthwhile option for those looking for a V-shaped sounding IEM.

Reviews
Empire Ears is a hifi audio brand best known for headphones featuring their proprietary Weapon IX 9mm rare-earth magnet "subwoofers" with bass-reflex systems. The company hand-builds synX crossover networks without PCBs, assigning more individual audio bands per driver than any other IEM crossover. They also developed EIVEC electrostatic control to integrate EST drivers with dynamic and balanced armature drivers.
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.
