Sooo, as someone PMed me to have a comparison between Oriolus Reborn, Mest MKii and U12t I though I would share it here as it may be useful for anybody who is interested in one of these iems.
NOTE: This is my SUBJECTIVE view based on my PERSONAL taste so take it as a grain of salt. What I may find important and pleasant in an iem can be less relevant to you.
And sorry for the long post
I like: Smooth and musical Iems with good separation of instrument. Impactful bass. Large soundstage.
I dislike: SIBILANCE. Sharp treble. Too forward High mids and vocals. In your head sound. Weak bass.
Background: Long time music enthusiast, I studied piano, guitar and now learning wind instruments (Sax, EWI and Ocarina). Played in a local band in my 20s (As singer/rythm guitar, Main Genres: Grunge, Rock, Punk). Now listening to many genres, from Rock to Edm, Ambient, Classical, jazz, blues and latino.
Testing and purchasing iems and headphones for the last 7 years. Had or tested around 100 iems, from TOTL to mid priced. Some of iems I had include Legend x, Phantom, Flamenco, PP8, SD5, Rhapsodio Solar, Solaris 20, Andromeda 19, Andromeda S, Vega, se846, Moondrop S8 etc etc. Full list in my profile, it’s really too long
Iems:
u12t+M20 module+leonidas II cable+sedna light (normal version) tips
Mest MKii+ stock cable+xelastec tips
Oriolus Reborn+pwaudio no 5 cable+spiral dots

FIT
- NOTE: I personally prefer a more shallow fit than deeper more invasive fit
Oriolus Reborn: 10
Reborn have the biggest shells out of the three with the shortest nozzles. Very Shallow fit with the spiral dots. They are very comfortable.
u12t: 9
With the sedna light they are pretty comfortable. The shells are smaller than reborn but they have longer nozzles
Mest mkii: 8
They are the smallest of the three with thicker nozzles. Fit changes the sound the most compared to the other 2. Xelastec tips are a bit tricky to fit in the ears but after a while they get softer. Still, to my ears Xelastec are the best tips sound wise with mest mkii
SUB-BASS
Oriolus Reborn: 10
The sub-bass of God. Nothing else to say. Rumbles like an angry God of thunder but does never bleed. It’s also very controlled (unlike the headache inducing legend x)
Mest MKii: 9
Very good sub-bass. Less present than Reborn but still rumbles and goes deeep when called upon
u12t: 8
While the u12t has fantastic bass for an all ba iem, it still does not rumble in your chest as the other 2 dynamic drivers based bass. Anyway, sub-bass goes deep and has impact, just less rumble-you-feel-in-your chest
MID-BASS
u12t: 10
Yes, surprising from and all Ba but the mid-bass of u12t is tight, punchy, with right decay and never bleeds
Mest MKii:9
Punchy and tight mid-bass with the right tips. More or less present/punchy depending on tips/fit.Good decay. Never bleeds
Oriolus reborn: 8
Still excellent mid-bass impact/tightness. It’s a bit slower than the other 2 but does not bleed into mids. I would call it an euphonic take on midbass (with no5 cable). It changes with other cable pairings, becoming tighter but I preferwhere it is with no 5
MIDS:
Oriolus Reborn: 10
Lush euphonic musical mids. On the intimate side.Love them.
Mest MKii: 9
Very Spacious and musical Mids, holographic. Low mids are more present when the shells are more in contact with the ears due to bone conduction.
u12t: 8
Mids are on technical side but with still enough warmth and musicality. NEVER harsh or fatiguing
HIGHS:
u12t: 10
Tia treble. Extended but smooth.
Mest mkii: 9
Extended sparkly treble. With good seal it’s not harsh or fatiguins
Oriolus Reborn:8
The highs are not as extended as the other 2. Smooth and on the musical side.
SOUNDSTAGE:
Mest MKii: 10
HOLOGRAPHIC soundstage with correct tips/fit. AMAZING
Oriolus Reborn: 9
More intimate (not as wide) soundstage than the other 2 but holographic.
U12t: 8
Soundstage here is as wide as mest mkii but deeper than both mest miii and Reborn. Sligthly less 3d effect than the other 2 as the presentation in more laid back.
MUSICALITY:
Oriolus Reborn: 10
What the Reborn loses in technicalities compared to the other 2, it gains in musicality. Warm rumbling bass, lush and intimate mids and vocal, smooth treble. Presentation is more on the musical/emotional side, quite holographic soundstage
Mest Mkii: 9
Toe tapping sparkly presentation. The soundstage is..wow, never heard such holographic thing from an iem. SOUND ARE POPPING FROM EVERYWHERE.
u12t: 8
More laid back presentation, technical iem but still musical. Less emotional than the other 2
TECHNICALITIES:
u12t: 10
Best technicalities of the three. Does EVERYTHING right and nothing wrong
Mest MKii:9
Excellent technicalities. Very Spacious iem
Oriolus Reborn: 8
Loses a little bit in technicalities compared to other 2 because of the treble but wins many hearts with its musicality
ALL-AROUNDNESS/SAFEST CHOICE
u12t: 10
The best all’arounder iems I ever had or tried. It’s a safe tuning, warmish laid back and musical. Will not always touch your heart like the other 2 but it would be the first iem I would advise to try to someone looking for a does-it-all iem and the one I would choose if I could only have one iem.
Mest MKii: 9
Slightly wins on Reborn for the unique soundstage presentation and technicalities. Love how sparkly yet smooth it is.
Oriolus Reborn: 8 or 10
Now, this personally may be a 10 but it depends on what you think is important in an iem. Do you want to be moved from the music, feel emotions or hear and analize every single details? Do you prefer technicalities over musicality? Do you prefer a warmish iem or a bright one? Do you like a more intimate or laid back presentation?
Ask these to yourself and choose the rating
To close the post, I would say that they are all three fantastic iems and they complement each other very well. I hope this not short post will help some people in choosing
