Up for review today are the Mangird XENNS Up (yeah, I’m not going to capitalize that every time – get over it). These beautiful IEMs come with a 10mm DD for the BASS, 4 BAs for the mids and highs, and 2 ESTs for the ultra-highs. They also have hand-painted shells which is a pretty cool touch. I got these as part of a trade from another Head-Fier, so I don’t have any links to share, but you can buy them from Linsoul for $700 if you feel like buying a set. On with the review!

Accessories/Earpads/Eartips (10/10):

Super nice. That’s the best way to describe the packaging on the Xenns Up. The box sleeve has the gorgeous art you’ll find on the shells all over it, which looks like flowing lava. The inner box is really nice and protective and it includes a splitter, a leather carrying case, and adapters for the cable to work with just about everything you could imagine. It also comes with several different “cards” worth of ear tips – foamies, silicon-ies…foam/silicone hybrids…you get the idea. It’s a better presentation than the $600 Meteor, the $1000 FiR VxV, and the $$1,100 Fibae 5. Heck, it’s a better presentation than much more expensive IEMs – looking at you FiR Frontier series. It earns a 10/10 here, and yes I’ll be using my Spinfit W1 tips since they're the best I've found (You can buy them here if you want a set:

Cable (8/10):

The Xenns Up comes with a decent cable. It’s a little thick and heavy for my tastes with some annoying memory retention, but it’s a better cable than comes with a LOT of more expensive IEMs (looking at you again Fir Xe6). It also has modular ends, which I can fully appreciate, though at this level if you’re not using a 4.4mm balanced jack on your DAP/amp, that’s a bit weird. So really, at this price, it would have probably been a better idea to just include a 4.4mm attached. Still, I appreciate the options, even if some will argue that this choice will decrease the sound quality and blah blah blah – those guys already own an aftermarket cable worth more than these IEMs - they can go use that and quit complaining. It’s not as nice as the FiR Rn6 cable, but it still beats a LOT of stock cables – 8/10 points here.

Build Quality/Comfort (10/10):

The build quality on the Xenns Up is fantastic. The Xenns have great build quality and comfort with a really nice hand-painted art pattern that’s unique to each set. On top of that is a clear coating that makes them appear seamless and they have vents to avoid pressure build-up. The IEMs design sets them comfortably in your ear with curved stems and the overall housing is pretty small compared to something like the Ronin/Mentor/Elysium. They will protrude a bit though, if that annoys you, as they are thicker than some. I have no reason to take off any points here, there are wonderfully designed and built – 10/10 points.

Check out the below. I’ve thrown quite a few IEMs on here since when I originally wrote this review, the Xenns Up wasn’t available in the U.S., and the price for it roughly translated to around $1,100. At the $700 price from Linsoul, it plays in a much more reasonable playground and there’s far less competition. At the price of the Fibae 5, the Xenns Up has no ability to contest it, but for $400 less, it gives the F5 a run for its money in value. Obviously, it has less sub-bass/mid-bass than the Meteor (closest competition) and the F5, but it’s still considered a bassier IEM. The mids of all 4 are very close and the highs are all over the place, so check out the individual song tests below for a clearer picture on what all of that means.

Xenns Up Meteor F5 VxV.png

I am powering these from my HiBy RS8 with the A/B amp on medium gain at around ~40/100 volume. I’m using Tidal Hi-Fi with MQA enabled and the 4.4mm jack with the stock cable.

Lows (15/20):

I’m starting off with the Mid-bass/Sub-bass test I’m using David Guetta’s “I’m Good (Blue).” There is really good, full-bodied mid-bass on the Xenns Up, with just a tad bit of unwanted distortion. There is also good sub-bass, though the wind-up is hard to hear. These are quite bassy, and probably one of the best bass presentations in this price range. It’s not Fibae 5 levels, but it is very pronounced overall – and drowns out the mids a bit. For the bass quantity/quality test though, these get near full points with a 9/10.

Up next is Demon Hunter’s “I Am A Stone,” which I use to test whether the bass is too strong and overwhelms the mids as that is just as important as how strong/good the bass is. The Xenns Up is not really a mids-focused IEM, as evidenced by this song. The bass is the star of the show here, and it does occasionally overwhelm the mids. It’s better than some bassy IEMs, but still very pronounced. 6/10 points here.

Mids (9/20):

Weaving The Fate’s “The Fall” is my test song for clean/dirty guitars and vocals with background instruments to see how clearly the vocals/guitars can be heard. The intro's clean guitars are very quiet, but clean and detailed. The dirty guitars come in muddy as a wall of sounds with no real definition. The bass guitar of course comes across quite strong here. The vocals are decent, but pushed pretty far back in a soundstage that feels a bit artificial. 2/6 points.

Staind’s “Something to Remind You” has clean electric guitars and wonderful vocals – this song tests vocal quality and background noise. This song can sound really magical on some IEMs – the Xenns Up doesn’t manage to capture that magic with its recessed mids and emphasized lows. Detail is missing and the vocals just sound OK – not the worst, but not the best. 2/7.

To test classical instruments in the mids, I’m using The Piano Guys' “Code Name Vivaldi.” Woah, there’s so much low-end presence on this it’s almost overwhelming. It really brings a LOT of emotion to this song, though the pianos and mid-cello are pushed back more than I’d like. This IEM is a bit of a broken record for me – lots of bass and pushed-back mids – still, it has its charms and this song is a good example of that. 5/7 points.

Highs (13/20):

To test sibilance on headphones I use Panic! At The Disco’s “High Hopes. There is not a ton of sibilance on these IEMs, but there is still a noticeable amount. They are definitely above average on sibilance though. 4/6 points - solid.

Dream Theater’s “The Alien,” is the highs test song I use to see if the cymbals/high-hats/snare drum can be clearly heard and distinguished from the rest of the music (also good for instrument separation.) There is some highs presence here, but it’s pretty muted and nowhere near the level of something like the VxV. That said, the Xenns Up doesn’t have the sibilance the VxV has either – it’s always a trade-off. Still, you can hear a little of the cymbals in the background, so it’s nowhere near the worst I’ve heard. 3/7 points.

Michelle McLaughlin’s “Across The Burren” is another of my favorite highs/sharpness test songs as it can easily sound painful on some headphones. I’m not really expecting any sharpness here based upon the two previous songs and I am not disappointed. The Xenns Up aren’t perfect on this song – there’s the occasional cringe note, but they get close enough for me to award them 6/7 points.

Soundstage/Instrument Separation/Imaging (6/10):

I use MGMT’s “Time to Pretend” to test soundstage, instrument separation, and imaging. The Xenns Up has pretty good imaging (3/3) on this song and a decent soundstage (2/3.) The instrument separation isn’t that great though (1/3.) 6/10 points here.


Update: Linsoul now has these for $700, which makes them a solid bargain under $1k – it also means they’re competing more with the Meteor which costs a couple hundred less. The below paragraph was written before Linsoul had them and they were harder to find, but it still applies so I’ll leave it in the review. I personally like both the Xenns Up and the Meteor, so just grab the one you want to pay for – the Xenns Up feels a little more premium than the Meteor, but I prefer the Meteor’s sound – you may not (some people like it, other don’t).

The Xenns Up runs around $1,100 if you can find a pair. That puts them in direct competition with the Fibae 5 and FiR VxV. To be blunt, I’ll take the Fibae 5 over these any day of the week if I’m looking for a bassy IEM – though the Fibae 5 will likely cost quite a bit more used. If I’m looking for an IEM with great Mids and Highs, but low bass quantity, the VxV would be my choice as well. The Xenns Up has really good sub-bass and avoids a lot of sibilance and sharpness, so these will likely please EDM lovers. Those in search of forward mids and great detail will need to look elsewhere and anyone looking for forwards/detailed highs should do the same.

Geez, I have never had to adjust the volume knob so much on a set of IEMs. That said, these are definitely a bass-lovers IEM. They are the exact opposite of the FIR VxV and the recessed mids and highs don’t play to my preferences, but they may to yours. I’d personally still recommend the Fibae 5 over the Xenns Up if you’re looking for a bassy IEM – it’s an all-around better IEM.

This is one of the IEMs that I've never had the courage to buy, both due to the high cost and the conflicting opinions I've seen and read.
However it is magnificent.
the UP is a source sensetive iem. I would try them with Ibasso DC04 pro or Shanling UA5 any warm source will do.


Headphoneus Supremus
Pros: -smooth balanced bassy neutral tonality
-great resolution and transparency
-effortless treble with beautiful brilliance
-fast attack
-excellent bass performance
-well rounded bass with natural texture and great balance
-clean open mids
-safe upper mids (no sibilance)
-safe yet exciting treble (snappy and generous in micro details)
-decent sound value
Cons: -bit thin mids
-not the most natural timbre (boosted in presence)
-EST treble could be more boosted
-lack a bit of note weight
-not for vocal or lush mid range lover

Personally I haven't try any Mangird products before, but read lot of good things about them. Its unclear if the company name is Xenns or Mangird, and it seem this company don't have official website. So, who know, perhaps it's one of those Linsoul sub-brand, but more official info will be welcome for a company aiming mid tier and high end audio products.
Anyway, this company seem to focus on hybrid and tribrid IEM, and there Tea 1DD+6BA get good praise.

When I know a canadian fellow have a pair of the Xenns UP, i can't hold myself to asking him a loan and thanks to Tone Deaf Monk generosity, today I will be able to review them.

Priced 700$, the Xenn Up are tribrid IEM with 1DD for low, 4BAs for mids and treble and 2EST for upper highs.

Let see in this review if the sound benefit is high enough to worth the asking price.


Since these are loan unit from a friend, I can't comment on packaging nor on cable which wasn't included.
Let's begin by saying those are chunky boi, but due to their organic shape and light resin plastic material, they are comfortable but not meant for deep fit.
Nozzle is big too, and I suggest you using eartips with similar nozzle size to get an open sound.Construction is OK, nothing mind blowing, but i'm a fan of medical grade resin plastic shell since it's very sturdy and hard to scratch, as well, when you drop it the shock tend to be less risky for driver inside due to low vibration transmission. Back plate design is beautifull, elegant, i like it. There a side venting port too. 2pin connector aren't embeded which is a questionnable design choice for secure connection, it seem the connection will loose with time, as it does with UM Mext and 3DT.
All in all, nothing to complaint about construction.


The Mangird Xenn Up is all about smooth balance which can be perceive as warm L shape with extra crispness on top to smooth W shape.
Sure, the bass is boosted here and even add hint of warmth to mid range, but this permit an organic cohesion that bluff the listener thinking he don't listen to a tribrid packed with drivers, i'm mean, if you go into intense critical listening, you might be able to pick up balanced armature timbre, yet the sonion BA are known for excelling in mid range and this is no exception here, the implementation is examplary and all about delivering realist timbre that is appealing to the ears.

So these aren't exactly neutral, nor what I would call basshead even if low end is quite boosted. And yes, apart the bass part, it mostly follow Harman target but not Moondrop way at all, this isn't a Blessing2, it's lusher, bassier and more natural sounding than that. The Xenn Up aren't cold or lean sounding: note weight is there, timbre density have hint of euphonic warmth and treble is snappy with this appealing brilliance that avoid dryness.

I really love the bass presentation of these since we have both mid bass and sub bass boost, balanced way. It's round, weighty, fast and just a hint warm in definition so transition in mid range doesn't feel scooped artificialy. It's a thick and juicy bass that have plenty of slam when calling for, the rumble is vibrant with short resonance so their no unwanted veil since it mix up with low harmonic naturaly. The extension feel elastic and versatile for wide range of impact and instrument, and while the punch have authority it never dominate whole sound spectrum, keeping it's layering quite clean. Sure it's a bit colored in tone, due to timbre that is a bit dark texture wise, but low region doesn't feel detached nor out of timbral balance.
For soul track from Gallant to Muni Long to Pip Millet, the bass had this engaging slam we need while vocal are upfront, letting bass response extend in the back. As said above, the rumble do not create alot of resonance, in fact, it's a bit tamed in natural decay and resonance too, which can be perceive with toms or acoustic kick, this will tend to denfisy the presence and impact weight.
I know a bass response is versatile when it's as good for kick instrument than for cello and contrabass, and we are in this rewarding territory. I adore how cello sound with the Xenn Up, it's not sounding like a violin when it go in lower octaves, as well, their this air vibration that is felt in the instrument body, without an over emphasis of texture that could distract us from pure tone.
When it come to contrabass, Lars Danielsson bass line sound fabulous on it's album Tarantella, the extension is clean and deep, the attack grip is well perceive, the tone and timbre is natural, in fact, even more natural than cello which confirm the Xenn Up are Jazz master that permit well layered bassist, clean open mid range that don't lack weight for piano notes and very fast and precise percussions presentation.
Yes, we are in this rare case of bass quantity meet quality here and saying it's addictive is an understatement.

At first, the mid range isn't what hook the attention the most, then you get immerse in it's richness and understand how capable and full sounding it is. The sonion balanced armature are beautifully implemented here and don't suffer from artificial or thin timbre nor too high pinna gain that can create shoutiness. Perhaps they have been customize, since i feel their hint of warmth to them as if dampened. So we have smooth, clean and detailed mid range, with natural timbre, incredible layering capabilities and good amount of lower mid range to permit good note weight, as well as dense enough male and female vocal. Again, Xenn Up nail versatility in this frequency range and the technical ability become more evident with complex tracks that are busy with sound layers since it's what stand apart here: articulation of all this sound info.
An interesting track that was very problematic with all my IEMs apart Final A8000 is ''Mars&Venus'' from Paul Epworth ''Voyager'' album, the Vince Staples vocal get either mixed up in fuzzy sound layers or too bright due to upper mids lift that try to create fake clarity, but with the Xenn Up, Staples vocal is smooth, natural, non sibilant yet have it's own layer space and is tonaly right, without any mudyness and presentation is both holographic and intimate, engaging and laid back, very impressive.
My benchmark instrument for mid range is the acoustic piano and the Up don't disappoint here, we feel the note weight, the decay is clean but not the longest. We never struggle to follow piano melody even in a crowded orchestra, yet, it doesn't feel force but effortless in it's well centered presentation.
These are transparent mids with class leading layering capacity that benefit all type of music from classical, to jazz to folk, eletronic and everything in between. We can say these are safe too, and a ''Jack of all trades, master of near everything''.
Only instrument that need abrasive attack and very textured presence will perhaps feel a bit too smooth, but this is more about treble section.
If i can nitpick something it will be that vocal and instrument feel a bit lacking in presence wideness, so they aren't presented ''bigger than nature''. As well, while not thin sounding, I don't think it would be lush or thick enough for some mid centric audiophile that like their mids very colored, it's too well balanced for that.

Ok, when we see that an IEM have EST drivers, this make us have wild expectation that often lead to underwhelming result in term of vivacity of treble presence, sparkle and extension. Let say while the highs are more brilliant and snappy than the Kinera URD using similar sonion EST, it doesn't mean the Up deliver a sharp agressive W shape tonality where the upper highs will be over boosted or ultra magnify, nope, in fact, the treble is even a hint dark with the UP. While crisp and well resolve, these aren't analytical IEM, it's too smoothly balanced for that. But this doesn't mean it can't dig lot of micro details, it just mean it's not agressive sounding on top even if ultra highs are quite sharp, snappy and brilliant in edge.
You can discover the EST presence with instrumental folk music, acoustic guitar plucking, harp, clavichord or with percussions, which sound phenomenal in sharp clean presence and crazy fast attack timing and control, in fact percussions part tend to attract our attention alot and amaze us with slightly cleaner and crisper definition, they add spatial cue and sens of much needed openess in Y axis.
You will not miss a single cymbal or hit hat strike with the UP, whatever lightning pace of the tempo.
Yet, even if sparkly, decay cut short, I mean, EST are so speedy that even resonance, sustain and decay are kept to minimal, with this sharp brilliance as a result this urgent highs delivery.
So while mostly smooth, liquid, transparent and gently detailed, the treble do have this spicy upper treble that might create wow effect or less positive distraction depending of listener sensitivity to anything pass 10khz.
What the Xenn Up treble isn't: thick, crunchy and fully boosted as a whole. To the contrary it's gently boosted in presence and a bit thin and dry due to how textured is transparency, but never to the point being displeasant or too cold. It's very well resolve with excellent layering and micro details rendering, these can pick up lot of sound info yet never going over saturated or fuzzy-trebly in resonance or distortion.
And good news, they don't boost background noise of bad recording, making them very versatile for different music genre.

Soundstage isn't the highlight of the Xenn UP, but with right ear tips it sound wide open enougn, just not very deep or tall.

Imaging in the other hand is quite good, thanks to transparent layering and precise treble, we don't struggle to pin point instrument position even if separation space isn't widest.


VS KINERA URD (1 dualDD+1BA+2EST-650$)

URD is darker, more U shape in tonal balance and more open in spatiality. Sub bass is more boosted than the UP, while less punchy in mid bass, so kick drum feel less tamed in dynamic with the Up while it's sub bass doesn't dig as deep, nor warm the mids. URD mid range is smoother, darker and more open, upper mids is softed too while pinna gain is notably more loud with the UP which have a more energic and textured but hint more compressed and intimate mid range. Treble of both these IEM is handle by EST driver but the overall tonality of UP being more energic and W shape, upper treble is more boosted so it deliver more micro details as well as sparkle and snap but the the cost of a less organic and laid back tonality as well as some spatial saturation with sound info. The soundstage is notable bigger, wider and taller with the Urd, center stage being more recessed yet clean, it feel deeper too. Imaging is a bit darker and less sharp and precise in positioning with the Urd. Timbre wise, the Urd is a hint dryer-brighter, less liquid and dense than the URD, violin will sound not as boosted in texture but offer a creamy naturalness that is highly musical as well as non fatiguing, but not perfectly define as more edgy UP presentation. In term of tone and vocal, I do find the URD more appealing since it have more low harmonic that add fullness and less upper mids presence that can overly boost texture, so while male vocal feel a bit thinner and more recessed with the UP, female vocal, especially soprano in loud passage, can feel too fowards and sometime a hitn shouty.

All in all, the Kinera Urd offer a more laid back and bassy U shape tonality with more buttery and smooth mid range and more open spatiality but isn't as well resolve and feel inferior in technical performance. Bass is slower and warmer, mids are fuller but leaner and treble is darker but again smoother, the Xenn Up pack faster more textured punch, brighter more detailed mids and sharper more extended treble.

VS GSAUDIO SE12 (8BA+4EST-1000$)

SE12 is notably brighter and more treble centric, it feel a hint more balanced V shape against balanced W shape of the UP. Why? Because the mids are a bit leaner and more recessed, thinner too than the Up. Bass is all about mid bass punch, its faster and better separated, but not as round and extended than the UP, so we have this fast BA woofer boom with good enough texture but sub bass is more about resonance than well textured presence UP offer. Mids are where i feel the UP is notably fuller sounding, more bodied and wider in presence, but not as clean and open than the thinner brighter mids of the SE12. Vocal are notably more pleasing with the UP, tone is more natural and full, presence is more stretched and enveloping, so overall balance with bass and treble feel more cohesive, less boosted in upper mids and spiky in highs. Treble is the most evident different here and let say its perhaps due to the fact it use 2 more EST driver since its quite analytical and way sharper and more vivid in detailed, near overwhelming with sound info sometime, and percussions can feel a bit too agressive and underline compared to overall warmer macro-resolution of the UP. Yet, this do create intense Wow effect at first, then can induce a treble overdose, unlike the UP which doesn't distract with micro details invasion. Spatiality wise, SE12 feel more open and airy but about same widness, just deeper taller. Imaging is superior, since it's an analytical clarity we have but it's not very realist and percussions cue will be wrong, too fowards.

All in all, SE12 sound notably more technical and vividly crisp than better balanced and fuller sounding Xenn Up. Vocal, tone, timbre is more natural with Xenn Up and tonality is more versatile. SE12 talent is all about treble and boosted clarity, yet, we get fatigue fast of it's clinical musicality.

VS FINAL B3 (2BA-500$)

Ok, this is just for fun so let's say it's impossible to compete technicaly against Xenn Up tribrid with only 2 balanced armature, i'm mean it's evident but I was still surprise to prefer the B3 musicality with certain music. Let's begin by what I prefer: tone and vocal are fuller, and overall dynamic sound less distant and tamed than the UP, the cohesion feel more natural and well rounded too, even warmer. Timbre is thicker, lusher. Bass is notably less clean and controlled, more warm in impact with less clean separation than the UP, its embrace and thicken lower mid range more too, thus this thicker lusher timbre. Yet, this bass fell thicker and more vibrant, but less clean and deep and lean in extension. Their no doubt the UP is more detailed and open sounding this time, it have greater transparency in mid range and more extended and crisp treble. Dual BA show their limitation in busy bassy music especially, where the B3 tend to go way more muddy than the UP. Soundstage is both wider and deeper with the UP and imaging have both better layering and horizontal instrument separation.

All in all, Xenn Up is superior in all regard apart perhaps vocal presence and fullness since their this hint of appealing warmth in them, but the tuning is less versatile and can go plain messy with some music at high volume, unlike the UP.


The Xenn Up are the first IEMs i ever try from Mangird and let say i'm utterly surprise by how talented they are technicaly and how well balanced they are tonaly.
To deliver this kind of smooth, transparent, engaging musicality without loosing cohesion between all these different drivers is a tour de force in it's own.
Sure, sound benefit diminushing return is present, but not as much as the Kinera URD for example, which offer a more colored tonality with darker resolution.
It's easy to love the Xenn Up, but not easy to forget the cozzy immersive musicality it offer, due to the great versatility of it's tonal balance.
Unless your a die hard fan of mid range and want it thick and lush and very fowards, the Xenn Up is a safe sounding IEM that doesn't lack dynamism and will please as much bass fan than high fidelity fans.

Big thumbs UP!

PS: These were loaner unit. I have no obligation to review them and just share my honest impressions with you because i feel like it.

You can buy those at Linsoul for 700$ here (non-aff link):

This is an interesting review because everyone else says the Xenns UP has below average techs.

I'm guessing the bassy tuning masks some of the midrange.

There also seems to be a lack of treble but this IEM has 4 ESTs? Why tho?
@WAON303 bass doesnt mask mid range, its well layered due to 4BAs dealing with mids and treble...and EST are well implemented. I guess its because this isnt a ''wow effect'' machine since its too well balanced for that. people tend to mix up tonal and technical performance imo.
@WAON303 has 2 ESTs. and the UP is a source sensetive iem. I would try them with Ibasso DC04 pro or Hiby r6 pro ii. Very natural with a bass boost that's it.


Previously known as TheDeafMonk
XENNS MANGIRD UP a new classification? "BASS-Fi"
Pros: ▪ Shell is super comfy, Build quality is top notch.
▪ Holographic Sound stage, Very Wide , Decent depth, Height is just ok. (Intimate sometimes , Sometimes 3D)
The UP can legitimately portray the venue's space ( Club, Big Studio, Small Studio, Garage, Open Air Concert that’s a rare trait I have found.
▪ Bass and Mid Bass are large. Great sub extension, bass just smoothly transitions into warm and fluid mid bass. No bloat on well recorded songs.
▪ Treble gets its own point as the graph leads you believe with this much bass the treble would suffer but that simply is not the case for me. ( See my point on sources below )
▪ You can easily tell well recorded music quality and really shines with it.
▪ Vocals are defiantly a bit laidback in a good way to give you a sense of warmth. Very clear & crisp vocals but still smooth like a Penon IEM House sound but with the proper amount of high frequencies.
▪ Micro and Macro Dynamics are very well done and the UP lets the emotion of the recording and mix forth to make the UP a very fun IEM.
▪ Absolutely Non Fatiguing.
▪ Percussion is fabulous , as was piano and instrumental.
▪ All genre's of music was enjoyable could not fault the UP here.
▪ Scales with power but was fine on all my dongles no worries off of my DAP or phone
Cons: ▪ Not for treble-heads or people who prefer a lot of top end of the music spectrum.
▪ Female Vocals a tiny tad thick because of the amount of Mid Bass ( Perfect for me )
▪ OMG Source sensitive. ESS was almost edgy, and a mix of sharp & edgy (The E1DA-SG3 normally very resolving was UGHHHH NO!, Cirrius Logic was beautiful from the DX160, AKM of the Geshelli Labs J2 was a perfect pairing. UP likes a slightly warm source IMHO.
Things I commented on previously with the UP:
Stage is more intimate that other IEM'S I have ( GS SE12 - Killer Stage ) That being said the UP never really left me wanting more and I honestly like this mix of intimate and wide hard to put into words the UP is special.

Not only is the UP super source sensitive but highly sensitive to poor recordings, people who listen to MP3 will find the UP plays back not great recordings exactly as they are. LOW RES. The UP will sound muddy and all the good things I said above are gone.

Now let's get into it a bit deeper.

Completely Subjective Audio Review - XENNS Mangird UP

Hello all: Thanks for reading my feedback.

I share my impressions as I hear them with my ears.
As all our ears are different shapes & sizes so what I hear as bright or bass heavy -you might hear as dull and Vise-Versa; just something to be mindful of.

What makes my ears happy as a sound signature is slightly more aggressive U shape. I love my Bass Sub and Mid Bass love it all actually; and in large quantity. With the Bass I prefer a faster decay the faster the better as to not bleed into the mids., I am treble sensitive and prefer a darker warmer replay with good extension.

I prefer the fast speedy bass of the Beryllium Coated Driver of my Xenns Mangird UP and KiwiEars Cadenza. Of course there are exceptions in the market - as I also find the bass of the Bio Diaphragm used in the Yanyin Canon special - has some special sauce like a 8" subwoofer that feels like a 12" Has the slam and some serious sub bass! And the super cool Copper Alloy Shell IKKO Obsidian OH10 does some magic to the bass.

My music Library is widely varied from; Metallica, Great White, Cowboy Junkies, Pink Floyd, Adelle, Melisa Ethridge, Hania Rani, Vilvaldi, Fleetwood Mac, Five for Fighting, Manskin, Poncho Sanchez, Jimmy Smith, Chopin, The Crystal Method just to name a few.

That dripple being said:
And as such here is my take on the: Khan (Bought with my $)

Cable after rolling I used is the Hakugei Peaceful Voice I could hear a slightly warmer ummmm; over the same cable than in a OFCC cable. That’s just me I never want to come off as a cable shill but thought I would share my experience with my journey with the UP.
Some cant hear cable differences but I can not in a way that does something magical but just sounds different from one another to me.

Not some detailed comparisons I can offer because I only have 3 upper end IEM'S to compare.
So I did lots of back and forth with my Resin EJ07M retuned with a 3db Sub Bass bump and the GS AUDIO SE12 full BA/EST set.

LETSHOUER Custom tuned resin EJ07M - I observed that the Bass was similar in it's speed and decay of the lows. The XENNS UP hits a bit lower with more note weight, authority and emotion. Kick drums kick ass!
The Up has a larger stage than the Ej's not as 3D though, Better depth again goes to the UP - many have commented how 3D Holographic the LETSHOUER's are and I would agree but the Up's stage sounds more enjoyable to me maybe call it more intimate but if honestly makes me enjoy it more with less fatigue. Sometimes I feel the EJ's are forcing me too much information around me instead of just letting me sit back and enjoy the music.
The EJ's male vocals seemed a bit thin and not as natural as the UP , I prefer the warmer more natural tonality of the Up.
Micro Dynamics are better on the EJ's plays with more emotion more things going on around you and sounds like a smaller venue vs the UP sounds more spacious in its depth and adds to its unique replay.
Female vocals on EJ are spot on and sometimes a tiny little bit thick on female vocals with the UP.

The GS AUDIO SE12 also using full on Sonion BA & EST is a sound stage monster its what's makes this one special.
Bass is large , super fast , too fast for me I like the slower decay and note weight of a DD. The tuning is more V shaped and has a lot more high frequency energy than the UP , making the SE12 a detail monster. I prefer the more laid back presentation of the UP.

The UP is a freaky special IEM. I did spend a crap tonne of time source, cable and tip rolling to get me to my special mix of perfectly balance of copious bass and silky smooth vocals with enough treble to give me the sparkly.
The Sonion BA and EST Drivers are superior to Knowles for me, they bring a smoother presentation to the sound less edgy than the Knowles.
I find Sonion EST have a great extension for the high frequencies that is perfect for me laid back and still detailed.
The UP does not cheap out anywhere. A great Implementation of a Beryllium coated driver for snappy Bass without bleed, thumpy fantastic note weight but still tight love it. Sonion EST65DA01 for the Ulta-high-frequency drivers, twin Sonion custom high-frequency drivers and 2 more Sonion 2300 series for the mid-highs. So the expensive BA & EST drivers do the magic. Its just the package of DD & Sonion that makes the UP different in its tuning and playback.

nice review mate! no turning around the bush. concise and precise.
Hello buddy! Is the Hakugei Purple-Peace cable? I thought the combination was really nice! Is it better than the original cable?Because I don't like to use adapters. Thank you very much!
Great review brother spot on. The UP will shine depanding on the source and the type of music you have like HIP/HOP, EDM, also, rock is amazing for me. the UP is a source sensetive iem. I would try them with Ibasso DC04 pro, Hiby r6 pro ii, UA5. @ToneDeafMonk


100+ Head-Fier
Mangird Xenns Up | Super Short Sound Review | Peanutbutter & 1/2 of the Jelly
Pros: + Warm "Analogue" playback, doesn't try to go for an overly articulated "HiFi" sound but still resolves well
+ Bass like they installed a miniaturised, industrial hydraulic press in each shell - thick, forceful, controlled, textured and wholly dynamic
+ Great clarity and vibrancy in the upper midrange
+ Delicate EST treble, applying gently dispersed treble notes that works well with overall tuning
+ Good imaging and some 3D - with shallow wide bore tips
+ Never sibilant, splashy or wince-inducing, always smooth as a wet seal
+ Almost no BA timbre that can be detected, thanks Sonion!
+ Satisfying and convincing note weight
Cons: - A smidge too much upper mids, can get shouty abrasive
- Would benefit from +1-2dB shelf from 5kHz-9kHz for a snappier, rawer experience
- Would benefit from more separation & wider stereo imaging
- Require the right tips to get proper stage dimensions. (strongly recommend shallow and wide tips like Spiral dots)
- Scales a lot with power, won't show you what it can do with a mere dongle from a phone
- Stage could be more immersive still, you'll occasionally be reminded that sound is coming from tiny drivers in an earshell rather than simply appearing from inside the virtual stage of the song.
For those who tried/bought the Thor MK2 ($399 Single DD) and wished for the complete package, this IEM is it. Fit is very good, it's not huge.

Thank you! That’s very helpful. The main reviews of the Volt were highly positive, they’re a few years old now. The Up, at least in the threads I pay attention to, has had more sustained presence. I recently acquired a used Up and enjoy it quite a bit. I’m a pretty big fan of the serial, and was curious if the volt would be a logical upgrade.

A serial fan, who tuning-wise, I tend to fall in line with has said some nice things about the volt too. Most of the other volt reviews are positive, but vague and recommend a $700 cable. Which turns me off. $799 seems a bit steep (for me at least) without being able to try first or easily return. They’re a beautiful set though
@LakeOfTheWyles yes I think I should have gone with the Volt instead of the UP back then. UP disqualifies itself for me because of its narrow stage and overly polite treble. Volt seems to not only have more treble energy but has also a more distinct EST flavor having 4ESTs. Wider stage is also an important factor.

I would personally look for an OG Dark Magician. I recently got mine and it's glorious. I'm into high end DDs at the moment. Another option would be Softears Twilight, but that's a bit more money..

Xenns UP: Clubbing under the sun
Pros: Guilty please - FUN
Takes you back to raving
Bery DD bass
Mids presentation
Cons: Dark treble (I love it but some people will miss sparks)
Doesn't come as a resolving pair
Sometimes too much is too much
Needs other pairs to shine, IMO.

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

graph (14).png

To begin with, let me preface UP’s sound by saying that this is the most specific and hard to describe set I’ve ever heard, but I’ll do my best to do it justice.

Generally speaking, UP is a very warm set, bass boosted and with a dark treble.

Let’s start with the bass region as it is the star of the show. Kicks with authority, rumbles when called, doesn’t 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 don’t feel the drivers power. Seems like when bass is not emphasized enough, it won’t 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 it’s pretty close to the tuning used on Mangird Tea, only slightly elevated to compensate for the overall bass boost this set got - it’s 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, let’s get into the special source, the warmth. UP sound signature is very hard to explain. It’s like all the replay is covered in a warm blanket. Not veiled, not distorted, just warm. It’s like you’ve added an instagram filter to the song.

Every note seems thicker, hitting heavier. And the even more “strange” 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, it’s less pronounced.

It’s 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 don’t find it to have much depth or height, but it’s wide enough to go along the tuning.

Imaging is good, even though sometimes it doesn’t feel pinpointed due to all the warmth.

Detail and resolution are also average or above average, but can’t compete with detailed monsters like Mest Mk2 or sub-bass monitors like Variations.

6. Test tracks

1. Lana Del Rey - Carmen/Million Dollar Man

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 UP’s 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. There’s 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. You’ll lose some detail on Lana’s voice on these tracks due to the tuning and bass emphasys tho. Instruments are warmer but still have presence on upper harmonics.

Clearly UP wasn’t 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.

2. John Legend - All of Me

John is singing in front of you while playing the piano. UP tuning brings John slightly forward, but it’s still close so no big deal here. His voice gets extra weight when it goes into upper notes, it’s 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 - it’s 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 - it’s not its specialization). It’s better for Male vocals, which was kind of expected. Its warmth blanket leaves out some of the details, specially on the upper regions.

3. Jay Cosmic - The Tunnel (0:58 - 1:15)

Sub-bass quantity and quality are definitely there. This is where UP’s 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.

4. RHCP - Throw Away your television

During the first 15 seconds of the intro, Flea's bass guitar passes the test with flying colors. When Chad’s drum kit kicks in, you’re 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 I’ve heard of this song, touché - not the cleanest, but one of the most “fun” ones. The electric guitar could use some more energy tho.

5. Laurent Garnier - Crispy Bacon

UP bring Gariner’s 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.

6. Cirez D - On/Off

A very balanced techno track that any unbalanced IEM tuning will change the song’s course.

UP colors it with a darker tone, emphasizing the lower frequencies, but still keeping some of the bells and whistles. Same as with Garnier’s, 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, UP’s warm signature feels nice and cozy, slowly showing its bass texture out. By 5:30 I’m back into a techno party waiting for that sweet sweet drop to start jumping. By 5:45 shills come back and you’re transported into a dark and sweaty disco, feeling the low frequencies around you.

Even if I’m more into balanced presentations, UP sure made press replay and get up. Touché, Xenns, touché. Thanks for the trip.

7. Snarky Puppy - Tio Macaco

Good timbre, good separation and coherency. This track appeals to a set’s soundstage and imaging. Xenns passed the test on all of these with average or above average marks - imaging gets slightly blurred when there’s busy parts and warmth comes in.

To this kind of genre, I can’t recommend this set since it adds a lot of coloration to the replay and falls short on some of the individual instruments' replay/detail, but still does a good job. Turns the track more into a fun jam session and less into a studio record.

8. Kendrick Lamar - King Kunta

As expected, Kendrick’s 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.

9. Aerosmith - Dream on

UP’s 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. It’s a different but fun and relaxed replay, still containing most of the track’s detail. If you are interested in this type of music I strongly advise you to check out HBB’s review of this set.

10. Slam - Vapour

I was going to talk about this song in this review until UP’s bass blew me off. If you get this set and like techno, try this song. Roar.

7. Comparisons


I’ll 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:

* Billie Eilish - Oxytocin
* Agnes Obel - Curse
* Daft Punk - Aerodynamic

1. EJ07m (Spinfit CP145, Tanchjim filters)

graph (11).png

EJ07m has more sub-bass quantity while UP compensates it with more mid-bass elevation and kick. Texture and speed is better on EJ07m. UP’s 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 UP’s warmth, EJ07m comes out as sparkly, while both being in the dark side. Overall air and extension always seem to be on Shuoer’s courtside.

Verdict: Overall, EJ07m has a cleaner presentation over UP, due to it’s more clinical/cool tuning, that some might even find boring - It’s 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.

2. Moondrop Variations (Spinfit CP155)

graph (12).png

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 it’s 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 you're at a beach party by comparison. Although Variations’ 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.

3. Bonus: Mangird Tea (Radius Deep Mount)

graph (13).png

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, it’s 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 wouldn’t 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 I’ve heard. I had to take some time and skim a lot of my library just to get the hang of it. It’s a very hard set to describe. When I heard it for the first time I liked it, but I couldn’t understand why. Guess the first thing I noticed was its kick, its roar.

I don’t think some people will claim Xenns UP has an audiophile tuning since it’s too colored. But so what? It’s FUN. I can’t recommend it as an all rounder for sure, but it’s 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 that’s up to yourself to decide. As HBB stated in his review, these are a “Guilty Pleasure” pair, and I agree.

I think it’s 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 “hate it or love it” set.

In an era of tier lists and “resolution” 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.

@Ace Bee Sure, kilo salt.

Land will come with less bass (quantity and quality) and mids won't be as forward. Will also come as more detailed due to the tunning. It will feel ALOT colder and more energetic - with increased fatigue as well. Technically, ball is slightly on Land's court. In my opinion they will fit completly different genres - Xenns will fit eletronic, hip-hop or old school rock better while Land will have better advantage on female vocals, classic, jazz, etc.

Land is more of an all-rounder will the UP will be more of a party guy. Xenns is less fatiguing and more forgiving.
Codename john
Cool review . I was going to pull the trigger on the xenns heard them and decided they weren't quite worth the money. Definitely below the Variations & the EJ07M. I really like the EJs. Very underated set. Variations are best in class for the price

This IEM seems to have the exact same shell material as ThieAudio Oracle, which I hate due to how cheap(light & thin) the material feels, as well as that same copycat, cheap looking & feeling silver nozzle and gold lettering. :thumbsdown:


Previously known as HarlanDraka81
Beryllium Coated DD FUN
Pros: - Powerful, tight but never muddy bass
- Excellent timbre
- Smooth with no hints of sibilance or sharp peaks
Cons: - Not as easy to drive as other iems
- Not for analytical, flat of detail oriented sound lovers
- Bass may be too much for some
The Xenns Up are the latest Tribrids released by Mangird equipped with a Beryllium Coated DD for the bass, 4 Sonions BAs for mids and 2 Estat for highs. I will not bother you with a lot of technical details. There are plenty of tech sheets online you can check yourself with a simple Google search. Let’s only say that the Xenns Up follow the new trend of tribrids iems recently released such as Est112, Variations, Oracle etc. etc. with a unique beryllium coated Dynamic Driver for the bass. The Xenns Up are priced 699.99 USD.
This review has not been sponsored in any way by Mangird. The Xenns Up have been purchased with my own money from Head-Fi classified.

I think It’s better to first address the elephant in the room: if you are into analytical, microdetailed signature iems you should stop reading now. Don’t waste your time.

The Xenns Up are not that, they are a fun, euphonic piece of HiFi kit that aim to please with their euphonic timbre and powerful bass without going into microdetail territory.

Are you still reading? Cool, it seems you like fun in your music. So, let’s start.

Equipment used:

DX300 Amp II mk I
Apple Music Lossless
Stock Black silicon tips. Stock cable 2.5.

The first thing that struck me was how beautiful and unique the Xenns Up were. From what I have read on Linsoul, every piece is hand painted. This mean that each piece is unique but they will all have in common the colours black, white and red. I usually prefer more understated designs but I must say that these look extremely good.


The shells are neither too big or too small and they have a semi custom design. They are very light and comfortable and I could achieve a good fit straight away with all the tips I tried. I finally settled with the longer stock black silicon tips as to my ears the sound was the most balanced and the bass was tighter. Your mileage may vary, but I noticed that with the other shallow fit stock tips and with the spiral dots tips, the Xenns became warmer, bassier and the soundstage more intimate and narrow.

Isolation is OK but they have two big vents for the Dynamic driver so they will not isolate as well as all BAs iems.

The stock cable is fine and I like that it has a balanced termination out of the box though I would have preferred a 4.4 termination.

However, a 2.5 to 4.4 adapter is included in the box (along with a 3.5 and 6.5(?) ones).
The Xenns Up are not the most sensitive and easy to drive Iems. They scale a lot with more powerful sources. With all my other Iems I have I’m usually staying at low gain on my DX300 but I had to raise to mid gain with the Xenns Up to get a good dynamic range and get a better control of the Beryllium coated DD. However, I think that most daps on the market nowadays will drive them fine out of balanced ports.
The sound profile of the Xenns Up is kinda of a V-Shaped fun, euphonic warmish signature which aim to entertain. “Kind of a V-Shaped” since the mids are not so recessed as a common V-Shaped signature but not positioned in the soundscape as a U, W or flat signature. I will briefly compare them with the iems I currently have, UM Mest MKii and Oriolus Reborn. I will not compare them with my benchmark U12t since the 64 Audio Masterpiece are more than double their price.


Ahhh that beryllium coated DD.
Bass is the star of the show in the Xenns.
If only Legend X had this DD driver instead of those 2 ever present Weapon IX drivers..why Empire Ears? Why?

Jokes aside, thanks to the beryllium coated DD, the Xenns have one of the best bass I have ever heard in an Iem. It’s powerful, it’s fast, it has all the usual good DD attributed with added benefits, read: it’s tight and never bleeds. Bass quantity in the Xenns is above average and will not only please basshead but also Audiophiles looking for a more planted bass shelf and a fun signature.

The bass is never bloated neither muddy and hits hard.

However, both sub-bass and mid-bass are pretty present in the whole presentation so the Xenns may not suit lovers of super balanced or analytical signatures.


Mids are rounded and euphonic. I don’t find them neither thin or too full and to my ears they don’t exhibit the usual BAs metallic timbre.

High-Mids are not as forward as Harman-Target tuned iems so the Xenns Up are very forgiving and easy to listen iems.

No sibilance or sharp peaks I could detect anywhere in their signature.

There’s good separation between instruments but not as much air as Mest MKii or Oriolus Reborn to name just two of my favourite iems.

Vocals are placed in the middle of the mix and not as forward as other vocal centric iems. This reminded me of the U12t vocal placement which hits my preferences very closely.

However, if you like the singer to whisper straight out into your ears and massage your brain, these may not be the iems for you. Go for the Mest or even better for the Oriolus Reborn if you mostly like vocals above everything else.


Smooth, clear but not forward. The treble extend fine but in a pleasant way. U12t and Mest MKii have more extended treble so do other iems such as Moondrop S8. But the Xenns treble is forgiving and inoffensive, perfect for long listening sessions.


Above average in depth/lateral soundstage with excellent imaging. 3d placement of instruments is there but less apparent than Mest MKii or Oriolus Reborn. Vocals are in the centre of the mix. Not forward, not recessed.

Iems like Mest or Solaris (or Oriolus Reborn even if their soundstage is more on the intimate side) still win with their holographic 3d soundstage.
Some songs that really impressed me with the Xenns Up:

Eli Brown - Pulling me back ft. Lovlee

Planet Funk - Chase the sun

Led Zeppelin - Stairway to heaven

Symphony X - Of Sins and Shadows

Enya - Caribbean Blue

Arthur Rong - Pulsar

Dire straits - Sultans of Swing

Ludovico Einaudi - Primavera

Calvin Harris - Giant

Montmartre - Our Time is now

Parov Stelar - All night



No, the Xenns Up are not as balanced and detailed as the U12t. Not as clear,airy and holographic as the Mest MKii. And not as intimate and emotional as the Oriolus Reborn.

They surely fall behind in technicalities even when compared to something like the Moondrop S8 but oh man do the Xenns sound good! Very good. So good I like them for the fun and smooth way they present the music. Even if the details in the music are not pushed forward and they are not as apparent as other iems.

And sometimes we just want to relax and enjoy our music, right?
Do I universally recommend them? Well, not universally.

If you are looking for an iem with powerful bass and no sharp peaks to sit and have fun, these may be for you. They are a real joy to listen to.

For more technical, detailed, flatter, sharper, harman target iems with prominent forward high-mids/treble signatures, you should look somewhere else. These may not be for you.

I have both the MkII and the XENNS. For my library and tastes the Mest is the clear recommendation, albeit at twice the cost. And while I enjoy the XENNS for all the reasons mentioned in this excellent review, I would choose the Thieaudio Monarch as my favorite in the price band.
Nice review sir. Does Up sound good with Prog metal like Dream Theater, Haken,...? Any better iem in its price range for this genre?
I view this being a compliment to my mest mk2.


100+ Head-Fier
A review on the Xenns Up
Pros: + Powerful Beryllium DD bass
+ Decent bass and treble extension
+ Good timbral details on bass and trebles
+ Non-fatiguing signature yet engaging
Cons: - High bass volume causing inevitable bass bleed
- Thin clinical mids
- Not as resolving as expected
Mangird Xenns Up ($699)


Mangird Tea is an iem that has its own following. It's a budget priced iem with a whopping 7-driver count and balanced signature. We shall see how Mangird Up does this time. This is a 7 driver hybrid consisting of 1 beryllium coated DD, 4 Sonion BAs and 2 Sonion ESTs.

I purchased this with my own money and I have no affiliations with Mangird.



Forgive my phone camera, but the Up is a nice-looking pair of iems.

- The faceplate is random
- It is hollow inside the iem
- In terms of weight, one of the lightest in my collection
- Fit is excellent



More V-shaped than Tea


Up's low end towers above Dunu EST 112 some 6 dBs higher. Though compared to Variations and EJ07 the differences are minor.

The good:

The bass makes and breaks this IEM. Its curse and blessing. It has been a month or two and my verdict remains the same. Your experience with this IEM will depend on whether you like this amount of bass shelf.

The bass is slapping hard and fast. The slam hits hard and decays fast. The beryllium driver has quick transients capable of dealing with some complicated lines. The extension is exceptional on both bass and treble side. This makes classical music somewhat of an interesting listen. I am hearing more timbral details from violin albums. The EST implementation certainly isn't bad here with sufficient air and details in the trebles. The presentation is also more lively than some of my other sets. In a grand scheme of things this is still a balanced of iem in terms of bass-to-treble balance.

I find that the Xenns Up benefits from a cable downgrade. One of the few in my collection that does. Reason is that the cable is also one of the few that reduces both bass and treble (probably 1-2 dB). The result is that I managed to reduce the bass bleed to acceptable levels, and the good things about Xenns Up begin to resurface. The bass and treble texture / timbre remains excellent, and it delivers remarkable playback with my DSD 256 violin collection.

The bad:

Despite the top quality bass, the volume is an issue. Not as clean as what I've heard on other bass boosted iems. I prefer bass boost that slopes down faster, at around 250hz. To clear the way for mids. On the Up I feel like my attention is being dragged to the bass, regardless of what is happening in the record. There might be tracks that benefit from this elevated bass shelf, but for my library it is over-emphasizing.

Technical performance is also sub-par, a little better than Dusk but below Dunu SA6. Struggling in this key parameter compared to iems half of its price. There are two tasks to detail retrieval. One is that the IEM is capable of picking up minute details. Second is the ability to present those details in a pleasing manner. To my ears it is thundering above the other frequencies and that makes it 'bass bleed' (?). It's hard to put into words, but vocals sound distinctively further away than usual. That leads to another description: 'thin' mids.



Long story short. For $699, expectations are much higher. Unfortunately I don't agree with the tuning and its technical performance is veiled behind a layer of bass.

I've enjoyed Mele more in comparison, since that bass shelf is a lot more in line with general tastes. Xenns Up is still a very fun set that I'd recommend for the self-proclaimed bass-heads. Take your faith to the test with this bass cannon.

What is your library? What kind of tracks?
A huge variety both in terms of file bitrate and music genre, I try to keep most in either 24bit FLAC or better.

I have a decent collection of instrumental/classical (e.g. Unamas - VIVA! The four seasons, Jazz at the Pawn Shop...etc).

Pop and just about any kind of it. Jpop, Kpop, CantoPop, Mandopop, American pop. Yoasobi, ZARD, Bump of Chicken.

Video game/Anime OST, ESTs. DJMAX ost.

Rock / Metal - the usual suspects: Linkin Park, Metallica, Nightwish, MCR.

Genre makes all the world of difference. Some reviewers say they're top tier for hip hop.
