UM Multiverse Mentor

Great set of iem with bass beautiful voices of artists and tone doen mids/Great separation soundstage and clarity .Only cons are the high price and no customisation

I've had my Mentors now for 2 years and still ABSOLUTELY ADORE THEM and have no compulsion whatsoever to try and top them. The level of detail, timbre, resolution, staging, imaging, fat yet controlled bass, sparkle, refinement and every other term , I could go on and on... I Love these these IEMs. The only thing I dont like about them is the relatively shallow / flat socket placement. The sockets have gotten loose and the cables now pul loose when putting them on or taking them off. On the upside, UM is doing the maintenance for me complimentary, I just need to take care of round trip shipping and they'll be out of my possession for approximately 3 months. But that's Okay and speaks volumes of UMs after sales service.

It's really a sensational set of IEMS.

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 (:
