Guys,
Unfortenately I have bad news.
I donât like my UPâs review at the moment so it wonât be released today. Also I havenât done a single comparition with other tribids yet, but I think that might go fast since I know them all by now.
Iâm going to a 3 day trip to Spain so it might take a while, tho.
In my opinion, the review of hybrid IEMs should be done with their original cable. The reason is in the many drivers that have different impedance and sound different with different cables! This can mislead prospective buyers. Iâm just sayingâŠ
^^^ Agreed unless stated why an og cable wasnât used.
It will.
10 char.
Ok. I appreciate the effort to make a presentation! Go onâŠ
Xenns UP: Clubbing under the sun
All photo credits belong to @Resolution that took some shots on my request. Thank you for that.
1. Introduction
Xenns (former Mangird) is a relatively new and unknown brand that made some waves during 2020 and 2021 in the 300$ golden bracket of IEMs when they released the Mangird Tea. The Mangird MT4 was released after the Mangird Tea but has not enjoyed the same cult following the Tea has. Some fans of the Tea (including myself) became hyped when news came that Mangird would rebrand themselves into the name Xenns and UP would be their first release. More hype followed when the driver configuration was announced: Xenns UP contains 1 Beryllium Coated 10mm DD for low frequencies, two Sonion 2300 series for mid frequencies, two Sonion customs for high frequencies, Sonion EST65DA01 for ultra-high frequencies.
Xenns UP enters the market with a 700$ MSRP, placing it within one of the most competitive brackets of the hobby currently (tribrids).

3. Sources and accessories
To get my impressions only flac files were used only. Both Shanling M3X and Luxury & Precision W2 were used, but in the end the final thoughts were used only with the set connected to L&P W2 on 4.4mm balanced using the stock cable and M3X as source only. As for tips, all the review was done using Spinfit CP100 medium size.
4. Sound Signature
To begin with, let me preface UPâs sound by saying that this is the most specific and hard to describe set Iâve ever heard, but Iâll do my best to do it justice.
Generally speaking, UP is a very warm set, bass boosted and with a dark treble.
Letâs start with the bass region as it is the star of the show. Kicks with authority, rumbles when called, doesnât bleed much into the mids and has a nice texture to it. One thing I have to note tho is that when listening to more bass anemic bass tracks, you donât feel the drivers power. Seems like when bass is not emphasized enough, it wonât come out as powerful and more loose.
Mids are slightly recessed due to the bass tuning, but still very present and with a semi-forward presentation very close to its predecessor Tea.
The treble on this set itâs pretty close to the tuning used on Mangird Tea, only slightly elevated to compensate for the overall bass boost this set got - itâs tuned as slightly dark and non fatiding, while keeping some detail. Treble extension is also well done, giving some air and separation between all the warmth. Some people might dislike this type of treble, I personally love it.
With the obvious FR curve out of the way, letâs get into the special source, the warmth. UP sound signature is very hard to explain. Itâs like all the replay is covered in a warm blanket. Not veiled, not distorted, just warm. Itâs like youâve added an instagram filter to the song.
Every note seems thicker, hitting heavier. And the even more âstrangeâ thing is that it still kicks above all that warmth, still brings vocals forward and still has some treble spark and detail. I know, crazy. All this warmth comes more prominent when the tracks get busy- on simpler tracks, itâs less pronounced.
Itâs one of those cases that a demo will be worth more than a thousand words. Hell, one million words.
5. Technicalities
Soundstage is above average, slightly outside your head. I donât find it to have much depth or height, but itâs wide enough to go along the tuning.
Imaging is good, even though sometimes it doesnât feel pinpointed due to all the warmth.
Detail and resolution are also average or above average, but canât compete with detailed monsters like Mest Mk2 or sub-bass monitors like Variations.
6. Test tracks
Lana is singing in front of you. She appears as if you were in the middle of the stage and instruments are correctly placed in front of you and on your side. Xenns UPâs warm coloration brings up the note weight to a whole new level - Her voice never goes thin. Low frequencies get very present and take over some of the higher frequencies. Thereâs still plenty of detail on the song but, due to the tuning, it loses some sparkle - which is still ok for me.
Coloration apart, UP handles female vocals pretty well due to its forward presentation. Youâll lose some detail on Lanaâs voice on these tracks due to the tuning and bass emphasys tho. Instruments are warmer but still have presence on upper harmonics.
Clearly UP wasnât tuning with this kind of library in mind, but for me personally, any set has to pass some vocal tests for me to even consider it, specialized or not.
John is singing in front of you while playing the piano. UP tuning brings John slightly forward, but itâs still close so no big deal here. His voice gets extra weight when it goes into upper notes, itâs slightly thicker than it should. The reason this is one of my test tracks is due to the details on his voice and because at around 2:24 his voice keeps going upper notes while some kind of subtle reverb effect is added. This is where UP falls short - itâs coloration is still adding too much warmth to the upper notes and the reverb effect gets too little attention, to the point of almost no notice at lower volumes.
I think overall UP handles vocals ok (good for the tuning, honestly - itâs not its specialization). Itâs better for Male vocals, which was kind of expected. Its warmth blanket leaves out some of the details, specially on the upper regions.
Sub-bass quantity and quality are definitely there. This is where UPâs beryllium coated driver starts to show up its claws. Texture is pretty good, not Variations level of texture, but close. Rumble is very present as well. Great replay.
During the first 15 seconds of the intro, Fleaâs bass guitar passes the test with flying colors. When Chadâs drum kit kicks in, youâre in for a threat. I usually only use this track to test the first 15 seconds, but I got hooked all the way in. One of the best replays Iâve heard of this song, touchĂ© - not the cleanest, but one of the most âfunâ ones. The electric guitar could use some more energy tho.
UP bring Garinerâs classic to a whole festival replay, makes you wanna stand UP and remember all the pre-pandemic raves. I usually prefer my techno tracks more balanced, but this kind of replay is more festival-like - Loads of mid bass kick, slightly less detail and upper frequencies, but FUN as hell. You feel every kick behind the warm tone, but you still get the clicks and clacks, even if less emphasised. Different replay, but a great and fun replay.
A very balanced techno track that any unbalanced IEM tuning will change the songâs course.
UP colors it with a darker tone, emphasizing the lower frequencies, but still keeping some of the bells and whistles. Same as with Garnierâs, it brings back the festival vibes and replays. Beryllium hits with authority and leaves no prisoners. By 4:30, when the music goes down to start building up again, UPâs warm signature feels nice and cozy, slowly showing its bass texture out. By 5:30 Iâm back into a techno party waiting for that sweet sweet drop to start jumping. By 5:45 shills come back and youâre transported into a dark and sweaty disco, feeling the low frequencies around you.
Even if Iâm more into balanced presentations, UP sure made press replay and get up. TouchĂ©, Xenns, touchĂ©. Thanks for the trip.
Good timbre, good separation and coherency. This track appeals to a setâs soundstage and imaging. Xenns passed the test on all of these with average or above average marks - imaging gets slightly blurred when thereâs busy parts and warmth comes in.
To this kind of genre, I canât recommend this set since it adds a lot of coloration to the replay and falls short on some of the individual instrumentsâ replay/detail, but still does a good job. Turns the track more into a fun jam session and less into a studio record.
As expected, Kendrickâs vocals are slightly forward and the bass kicks with authority. Vocal is thicken, but you still get the melody and all the bells and whistles. Xenns UP brings a great yet warm replay to this genre. Hip-hop heads that like warm signatures might have they end-game right here.
UPâs warm signature and forgiveness work really well with older records like this one. Bass guitar is more prominent while high note vocals (3:30) and electric guitars get smoothen out, reducing its natural fatigue. Itâs a different but fun and relaxed replay, still containing most of the trackâs detail. If you are interested in this type of music I strongly advise you to check out HBBâs review of this set.
I was going to talk about this song in this review until UPâs bass blew me off. If you get this set and like techno, try this song. Roar.
7. Comparisons
Iâll now compare Xenns UP to another two IEMs in a Tribrid Deathmatch. Every set will be using 4.4mm balanced and stock cable. All of them are running from Luxury & Precision W2 (Low gain, Tune 02, no EQ) with flac files. I listened to a lot of tracks on all the IEMs, but I used the following three to bring the divine judgment on:
EJ07m has more sub-bass quantity while UP compensates it with more mid-bass elevation and kick. Texture and speed is better on EJ07m. UPâs mid-bass kicks you way harder in the chest, once again, bringing those live stage vibes.
Mids presentation is pretty close on both sets, although the warmth on Xenns UP makes voices thicker/meatier. EJ07m voice presentation is a little bit wider.
Treble presentation is pretty close as well, but due to UPâs warmth, EJ07m comes out as sparkly, while both being in the dark side. Overall air and extension always seem to be on Shuoerâs courtside.
Verdict: Overall, EJ07m has a cleaner presentation over UP, due to itâs more clinical/cool tuning, that some might even find boring - Itâs more balanced. UP is the fun friend that turns libraries into parties.
Technically, EJ07m is on a level above Xenns UP - Overall detail/resolution, imaging, staging.
The mirror enemies finally meet. Cold vs Warm. Sub-bass vs mid-bass. Sparkle vs Bright.
Sub-bass is a no contest in favor of Variations best-in-class texture and presentation. But what about mid-bass? Mid-bass is one of my personal nitpicks with this set. This is where Xenns UP will win since mid-bass on Variations sometimes feels non-existent.
Regarding mids, I prefer Xenns UP presentation, even if they are elevated. The vocals on Variations feel pushed more in the background that I like (YMMV).
Treble rolls the exact same way as sub-bass in favour of Variations. Variations treble is less on my preferences, I usually prefer darker trebles, but credit where itâs due - Variations treble is awesome with some nice implementation of those EST drivers.
Verdict: Variations as a sterile presentation of the sound, while Xenns makes you feel youâre at a beach party by comparison. Although Variationsâ sub-bass and treble are best in class, I prefer mids presentation from UP. To put it briefly, to my library, Variations is to find detail and stains on records while UP is to enjoy a sound. Both are great at what they do, but they do completely different things - if Xenns put a warm instagram filter on, Variations reduce the saturation and increase detail.
Technically, Variations turn the arena into a bloodbath. With some Monarch pedigree on its ADN, Variations is a tough bone to chew on.
Disclaimer: Mangird Tea will not use stock cable since mine came as a bit funky - as been replaced for a 1:1 silver cable for the matter.
I decided to add a quick observation to answer one of the most requested takes on the internet - Is Xenns UP the upgrade to Mangird Tea?
In short: No, itâs not. Teas are more balanced, slightly warm but bring a more balanced vibe with a sub-bass focus on the lower end, while Xenns focus heavily on warmth and mid-bass. They do share some of the mids and treble presentation, but I wouldnât consider them alike besides the house branding.
To this day, the closest to a true upgrade from what I love in the Mangird Tea is EJ07m (with tanchjim filters).
8. Conclusions
As mentioned above, Xenns UP is a completely different take on everything Iâve heard. I had to take some time and skim a lot of my library just to get the hang of it. Itâs a very hard set to describe. When I heard it for the first time I liked it, but I couldnât understand why. Guess the first thing I noticed was its kick, its roar.
I donât think some people will claim Xenns UP has an audiophile tuning since itâs too colored. But so what? Itâs FUN. I canât recommend it as an all rounder for sure, but itâs a good set to pair along with some more detailed and cold sets. It switches the gears, it switches your library for good or worse, and thatâs up to yourself to decide. As HBB stated in his review, these are a âGuilty Pleasureâ pair.
I think itâs a fine recommendation for specific genres like Hip-Hop or Electronic music for people that like ultra-warm signatures. Although, I strongly recommend trying to demo this set before buying. To my ears, it falls under the category of the âhate it or love itâ set.
In an era of tier lists and âresolutionâ seeking, Xenns comes in to shake things up (pun intended) and remember us that not everything is about hearing the best scratch on a vinyl - sometimes it is just about having fun while doing the most important thing - enjoying music.
Thanks once again for the pro juiced photos. 
Bravo, well done! This comprehensive review puts many HFI reviewers to shame.
The review is TOP, thanks for that! But also include modern dynamic songs, such as Jason Richardson for guitars and Luke Holland for drums,even if you don`t listen to them 
It will be very useful 
I get your point, and iâll amuse you about my picks.
Xenns UP is tuned to be FUN. Thatâs any hyper dynamic genre with specific traits. I didnât include stuff like that on a purpose. Not to make it look good, but just because I donât think itâs meant for that. I canât see why a person would buy a set like Xenns to ONLY listen to JR⊠Or vivaldi, or Max Richter. It wonât make sense, imo.
Iâm not confortable giving my word on prog, but I know âTitanâ from JR. Only set 2 sets I own that can keep up with it is Teas and EJ07m. EJ07m seems to be the best tribid for prog, but Iâm pretty sure picks like 3dt, fh7, zen, dq6, mest mk2, etc⊠Will âcrapâ on it. Anyway, this is not my expertise area, so I will have to summon my mentor @Resolution for prog metal.
Thanks, a really interesting read and well written 
(and your English is probably better than mine 
)
Super detailed review bro, you nailed it 
Thanks everyone also a public thank you to @hawaiibadboy since itâs his own set.
I had fun doing it and jamming to UP. Itâs a true party starter.
A special thanks to my iem brothers and sister. Thanks for letting me troll you everyday.
Thanks for the comparison. How about EJ bass vs Variations?
Iâll probably do a comparition soon since my Variations will be up for sale in a few days.
Variationsâ sub-bass has slightly better quantity and texture than EJ due to tuning. Anything else is better on ej for my preferences and library.
Feel free to ask me about the prog metal/metal genre. As @nymz mentioned, out of all of the tribrids I own, the EJ07m is my preferred IEM for the genre. You wonât want something with a lot of boosted sub bass for metal and you need drivers that can keep up with the transient speeds.
Xenns Up would be one of my last choices for the genre.
Those are my pics and Iâd also add the EJ07m to that group.
Are the BA drivers of the 07m Sonion 23 series and how do they deal with the dynamics in the mids?. Is the dynamic driver fast or lazy in comparison with FĐ„7? FH7 is very good, but the timbre and tonality are a bit bad! Hybrids and tribrids, in my opinion, are better for progressive, because they have a better soundŃŃагД and images than DD. Some planar IEMs also have fast transitions.
I dislike planar IEMs for metal because even though their leading edge of transients is extremely fast, they lack the note weight and overall slam of a dynamic metal requires to sound powerful. They just do not move much air but they have great resolution characteristics.
Of all the tribrids I own, I feel the EJ07m has the best tuning and driver hardware for the genre. It is very fast, yet still hits hard enough for the genre.
I agree that tribrid and hybrids have a unique sense of stage and imaging vs other IEMs such as single DD, and if you prefer that sense of stage and imaging the FH7 and the EJ07m will suit you well for the genres due to their snappy DDâs and neutral tuning and overall resolution, but you will be losing out on some dynamic slam a single DD set such as the Zen can bring or the triple DD beast the 3DT.
