Comfort/build quality/cable: The MM is extremely comfortable for my medium sized ear canal, the fit is very secure, especially with the included AZLA tips. The passive noise isolation is also great. I find myself using iems as an earplugs in loud environments quite often and these work nicely for that.
The build quality is outstanding, the shells feel very premium and look absolutely stunning in person, probably my favorite looking iem to date.
The cable doesn't seem to be microphonic to me. It isn't light but not heavy either, the weight is just right. Very comfortable for hours and it does feel extremely premium, just like every other top of the line PW AUDIO cable.
The sound: Just like the Mason FS, the vocals and string instruments presentation on there are on another level, way above everybody else.
I've never heard an acoustic guitar and violin sound so authentic in any IEM. It actually sounds like you are playing the thing without the vibrations of it against your body. The vocals sound like the person is singing detectly to your ears and you can feel it in a way. I've never had so much fun with any headphones in my life, let alone an iem.
The tonality on MM is unmatched. I often do prefer there over my Genelec studio monitors for pure musical joy that UM bone conduction gives me and that is saying something. Even amazing sounding speakers can sound somewhat lifeless after these.
Overall the MM are extremely nuteral, dynamic, crisp, enjoyable, fun and everything in between.
The low end is extremely well controlled, very balanced and as punchy as you want it to be even for metal/djent/thall type of genre.
The soundstage is stupid wide. Wider than Mason FS, Mext and my trusty U12t's. Imaging is spectacular, I would say The best on any iem that I've heard in recent years.
The course: depending on the source, you could or couldn't feel/hear the UM bone conduction properly. With some daps/amps these become just a great sounding IEMs, with some it completely transforms and makes you feel and hear the music like never before. I do find them to pair best with the Cayin products (N8 II, C9 amp, HA-300 MK2, RU6 etc) and LP6. The better the source, the better they will sound. I personally run them through my Cayin C9 amp with an external dac and I'm very pleased with the sound.
Negatives: There is one negative for me personally.
I do find them unusable for tracking, It just doesn't feel right. I often do prefer to wear an iems when I'm tracking and practicing guitar so that was a little bit of bummer, but I already knew what I'm singing for after purchasing my very first UM product.
Conclusion: If you can afford these, please do yourself a favor and buy a set, I'm extremely happy with mine after 9 months of having it and can't recommend them enough.
Otherwise please do consider getting the MEXT, both are fantastic, the MM just gives you way more and has a better control over all of the frequency spectrum.
Very coherent tuning without flaws
Best BCD implementation I ever heared
Superb bass quality
Big and holographic soundstage
Great design and build quality
The UM Multiverse Mentors are simply the best IEM’s I’ve ever owned. I couldn’t be happier about the purchase. I was stunned about what a major step up in performance these were from my Empire Ear Odin’s. Thank you to Andrew for all his help and MusicTeck for getting this shipped out so quickly. Highly recommended.
Multiverse Mentor is the best IEM out there.
When you put it on your ear, it starts live and becomes a 3D holographic space.
It is also awesome. It brings everything to your ears, from the expressiveness of the instruments to the artist's breath.
Multiverse Mentor is the only IEM that can be enjoyed on a vast sound stage without getting bored!
Unique Melody has created an extraordinary IEM.
Perfect sound is exactly what it sounds like.
Thanks to music teck for providing this.
And thank you Andrew for providing this.
I was lucky being able to demo this IEM before and could thereby figure out its abilities.
This IEM has wonderful mids with nice body, a holografic stage which is the best I‘ve heard yet and I‘ve heard quite some IEMs including Trailli which is no slouch in these regards and some nice engaging signature without getting harsh.
You can get different signatures depending on the source like maxing out the stage and having an engaging and thrilling experience with a smooth oraganic presentation with Cayin N7(even better with C9 attached), maximize organic lushness and punch on RS8 or even go beyond using an IEM friendly desktop stack like my Ferrum Oor with Hypsos fed by Holo Spring 3 KTE where these small green earspeakers are playing next to big TOTL overears like Meze Elite and good boy, that setup is maximing stage and lushness with detail without ever getting too harsh.
Big thanks to Andrew and Grace for their excellent service - you have won me as a lifetime customer for some time and I‘ve never been dissapointed but always enjoying getting back to you!
