UM Multiverse Mentor
I just got my new UM Multiverse Mentor IEMs. These are more vocal/mid forward along with treble forward. The bass is good for a Balanced Armature driver and is completely adequate for most music. However, it's not a bass head kind of hard-hitting bass. I'll get right to the point. These have the best implementation of Bone Conduction that I have tried when it comes to creating a wide 3D holographic soundstage. It really accentuates the "3D holographic" part where you feel the sound surround you. These IEMs can be used for any genre of music, but to me their strength is in the Acoustic music(guitar), Heavy Metal, Rock, and vocal/singer's voice being focused on tracks. These IEMs are at the very top of endgame IEMs for these types of music genres where the vocals are the focus and any type of Acoustic guitar songs with instruments that benefit from extra treble detail.
*If you want the best pair of IEMs for Rap, EDM, or any other Bass heavy music. These are not for you. Having said that, these are an essential part of anyone trying to gather a collection of endgame "TOTL" set of different IEMs that cover the various genres of music.
I shall not write the detail review for MM here. There are 2 review from @twister6 , @Visceral in headfi which is pretty close to what I heard from MM.
Just want to shout out to Andrew a big Thank you for the excellence customer service and accomodate to my request. Will definitely patronise/deal again if I have any upcoming item in my wishlist (:
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.

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.
So the BASS there’s a lot…a lot of it. If I had to describe it in a physical standing structure. It’s a wall af bass that is equivalent to the Great Ice Wall in Game of Thrones. While the midrange being a grand passage through and the details being the tiny Crows standing guard.
I have reached my journey of a bassy set. The bass is standing the boundaries of muddy bass. However it’s staying in the boundaries as a faithful guard dog not venturing beyond the property line.
I have found the bass to be unnatural, when applied to most music. Genres I have found most suited is Rap, EDM m, Some Techno, Male K-Pop & 90’s to Modern Metal. Details are far..far in the background and will bother some that know their music tracks well.
The separation is moderate and imaging is just okay maybe good at the best, depending on music. This is certainly a niche tuning of an IEM and will likely not a daily driver.
I don’t regret this being in my collection and Iove booming my friend’s heads with it. No one yet has said they hate it…..just WHOA & WOW.!!!
There is some driver flex at times, but that only occurs when inserting not wearing. I have the basic cable, but would recommend a high output source. So I applied a balanced 4.4 and have best results with a minimum of 200mw.
Wide bore tips have been best to squeeze out as much detail as can be found. TRI Clarion, Divinus Velvet Wide Bores and Moondrop Spring tips achieved this.
I recommend for the collectors and the brave. Reference folks not so much though.
Pairing this with the Eletech Ode to Laura has been a game changer for me with this IEM. It transforms the Fei Wan into it's absolute perfect form in my opinion. The bass hits harder, is more controlled, and tighter. The Vocals/mids get pushed forward and are completely transformed with lots of detail and imaging, and finally the Ode to Laura completely tames the Fei Wan's treble peaks with certain music while still retaining the same resolution and detail retrieval as it has with the stock cable. The tuning transforms from a V shape into more of a W shape.
You no longer have to find a specific Ear tip to calm the treble peaks down. I was able to switch back to the Azla Sednaearfit Crystal Standard tips and now there is no longer a negative treble impact by using a treble enhancing tip.
I don't know what kind of voodoo magic Eletech puts in this cable, but it really makes the Aroma Audio Fei Wan one of the top 5 end game IEMs available today.
Thanks
