There has already been written a lot about this wonderful set. I’ll add some subjective impressions:
I absolutely adore its warmish tuning while being super resolving and holographic with very wide stage.
It‘s a very vague and super subjective description but the MM’s have a (sorry😊) „emotional“ quality that my other sets (EE Raven, FIR RN6, CA Astrolith) don‘t have. It‘s really a complementary IEM to my little collection.
I‘m very impressed and have to give it 5 ⭐️
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.
Amazing technicalities
Very coherent tuning without flaws
Best BCD implementation I ever heared
Superb bass quality
Big and holographic soundstage
Gripping representation
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.
This little dap sounds incredible. One of the most beautiful sound I ever heard from a little dap. Hard to put it down. Easy to drive hps using the 2.5mm or the 4.4mm output this dap rocks! I've tried with some of my hps like the denon d9200, hifiman ed. X, and just wow...ridiculous good. The bt sennheiser momentum 4 sounded great also, will be bringing it to the gym. It didn't play well with the focal utopia. Also for some reason the denon d7000 3.5mm jack adapter did not work well. It must be easy to drive then. Overall it's a great experience. The UI can be a bit slow at times.
Great Case, great sound, good power, no issues. Very enjoyable.
Had the original Mest and Mest Mk IIs and loved them, but sold them to explore other brands - owned the Effect Audio Gaea, Elysian Annihilator, Thieaudio Prestige LTD - and came back full circle to the Mest series with the Mk IIIs. Just overall a beautiful sound with a sprinkle of special sauce from the bone conduction driver. Sound is smooth and non-fatiguing. Shell also fits well and looks great!
I like to try most of the TWS earphones released. So far I did not like any of the Noble TWS, but these ones won me over. The dual drivers produce details and enough bass for my taste. Of course, we talk about audiophile tws, so the other features such as ANC are not great. You won't carry them for a run or exercise. But walking outside, while commuting, they are good. They have the best sound signature I found so far with TWS of any price.
