UM Multiverse Mentor
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.
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.
The Fei Wan has swept me off of my feet! I thought I knew what dynamics were but my mind was blown once I heard Fei Wan. It’s a wonderful all rounder for me, with a cable swap and a tip roll I’ve been able to mitigate some of its mid treble spice. And this is prob the only area of contention. Everything else is amazing. As mentioned dynamic swings, razor sharp imaging, a tidy stage with more depth and height over width. Layering is superb, it is highly technical but still has soul and brings out the emotion in my music. Incredible bass response that doesn’t bleed into the mids. Mids have a balanced note weight and sound authentic. Treble is clear and precise with just a little spice in the mid treble. However everything sounds real and natural here although a bit intense at certain times. This is my favorite set of iems I’ve heard so far in the hobby. No set is perfect, and every iem has a negative but in this case the positives are overwhelming in the best way possible.
My first impression was woah...this thing actually has mids & treble! Bass is very manageable on most songs, and absolutely insane on some songs. I can feel the bass down to my toes while sitting. Hip-Hop & EDM just slaps (feels like there is a subwoofer in my room, with just the IEMs in my ears). Even non-bass songs sound pretty amazing.
My only complaint is the "upgrade cable" is simply not worth it in my opinion (feels cheap, looks ugly, but sounds good). Very surprising and special IEM!
I have had a lot of players, From Asten Kern, to Fiio M17. Both were good players, but this one is the best. Easy to use, plays anything, sounds amazing, I hearing things I, didnt hear before. Also helps that I, borrowed my freinds.
HIFIMAN HE1000se for a couple of days only to realized I, would have to get one ASAP. So much for that early Vaction this year! Yes I, will go but will have to wait months now because of this. While I, save for Vaction Month by Month I, will be on Vacation everyday I, get to listen to this Player. Thanks to all the People at Musictec for all the help. Later guys Luis
Pros:
-Staging (depth and height is some of the best i've heard to date)
-Imaging (space between instruments is the best i've heard to date)
-Resolution just TOTL level
-Vocals (female particulary a strength)
-Acoustics and (live) are just superb
Cons:
-Treble needs a bit of refinement (cymbals and anything within that frequency range 4-5kish seem to come across as a little shrill)
-Big shell/stem and weight can be an issue for some.
-Cable synergy can be seen as a con or pro but can be a cable chameleon.
-Hard to drive for full potential.
-Stage width (but still very good for an IEM)
Recommendations:
cable: Beat Audio Oslo mk IV 8 wire
Tips: Canal Works CWU-GDECA / Eletech Baroque
Best treble in the market. Period. Annihilators are my current end game when it comes to iems. It has solid bass and extremely good treble, whilst not sacrificing the mid range. Definitely would recommend it!
