UM Multiverse Mentor










These earphones are just excellent. My end game iem
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

Best BCD implementation I ever heared
Superb bass quality
Big and holographic soundstage
Gripping representation
Great design and build quality
THE BEST MY EARS HAVE HEARD!!!
She thicc. Big sound, dense and rich and strong. Not for neutralheads.
Focal Utopia-esque sound in small form. Beautiful shells.
Experiencing many different cables I was browsing to select my next one after attending canjam nyc 2025. I came across this little device and it was beyond intriguing. After using it - I can honestly say it’s a permanent part of my chain. What does it do? Well it’s sorta like adding a passive tube to your chain as everything becomes incredibly 3D but unlike tubes they may leave a haze or loss of really deep bass it does none of that. Imaging is sharper, separation more distinct while clarity and a black background are improved as well. For the price I feel like this is a bargain as PW Audio products go. Thrilled to own one.
Chain details black gate modded wm1am2, first times adaptor, 1960s to jade multiverse.
Great performance, one of my favorite IEM.
Without a doubt well worth the money. Paired with my IE900’s they are the best they have ever sounded. Empire Odin also superb. Perfect for no fuss setup. Musicteck shipping to Canada very quick. I have not listened to other dongles but I do have Chord Mojo2 and Hugo2 and have not bothered with them since the W4 arrived. For IEM’s it’s a no-brainer.
