What if you spend more?
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.

Our take on the brand
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.
