Tangzu x HBB Xuan NV

TangZu X HBB Xuan NV review and comparisons.

I would like to thank Linsoul Audio for sending me these great-looking in-ear monitor (IEM) earphones for a review. Linsoul Audio never told me what I could or could not say. I have no money to gain from this review. Rest assured that everything I say will be in my own words.

TangZu Audio is a relatively new audio company based in China, and TangZu X HBB Xuan NV (79 USD); a dual dynamic driver configured IEM, is a collaboration between TangZu Audio and a popular YouTuber and audio reviewer, Hawaiian Bad Boy, or HBB. His YouTube channel's name is Bad Guy Good Audio Reviews, but I think he is a good person.

The TangZu x HBB Xuan NV is one of the few IEMs that made me smile upon first listening. It sounds better than some IEMs I've heard that cost many times more. If you were to listen to them side by side like I did, man, I'm sure you'll be smiling too.

It looks stunning in person, especially if you like the color red. Personally, it reminds me of candy. And the finish is shiny and seems durable, as I haven't seen any scratches in the week that I've been daily using it, in a hard case when in my pocket.

The uboxing experience is just okay and aligned with its price, but the box looks good enough to be worth keeping.



Eartips and cable:

The effects of the eartips on sound are subtle but can't be underestimated. There are three types of tips included: the first is the white one, the one pre-installed on the IEM, which sounds the warmest; the second is the Tang Sancai normal bore tips, which sound average; and the third is the Tang Sancai wide bore tips, which, to my ears, make the IEM sound more like an audiophile type of tuning; it has the best technicalities in sound but sacrifices the bass presence just a little; this is the tip I like most, and the one I used in this review.

The cable included is average in quality for the price of the set; I upgraded it to a thicker and higher quality XIHNS cable.


Synergy:

The TangZu x HBB Xuan NV is not fussy about sources when it comes purely to sound quality, as it is not tuned for critical listening in my opinion, but it is revealing enough, at least for me, to reveal the subtle differences between the sources I tried it with.

Sensitivity, power handling, distortion, and amplification:

The TangZu x HBB Xuan NV is less sensitive than average; I have to pump up the volume about 30 to 40 percent more to match the loudness of my other IEMs on average. It may not be fussy about pairing purely for sound quality, but its low impedance, hence a difficult load and lower sensitivity, needs a powerful enough amplifier to reach its full potential.

I find the Moondrop Moonriver 2, Moondrop Dawn Pro, and Hidizs S9 Pro Plus Martha in balanced mode with a 4.4mm connection to be more than adequate for my needs. At 75 percent volume, they can drive the TangZu x HBB Xuan NV to very loud but safe volume levels, but when I reached 85 percent volume, the output protection on the Moonriver 2 and S9 Pro Plus Martha would kick in and cut off the music intermittently. On my bigger sources, such as the Fiio M15s DAP, Topping G5 DAC/Amp, and FX-Audio R07 desktop headamp, there was no problem driving the Xuan NV to a very loud volume, and it can take high power and go very loud without obvious distortion.



Sound signature, tonality, coherency and dynamics:

Bassy, warm, neutral, and energetic: The bass is obviously boosted but never overbearing, the overall tonality is warm, and the midrange and treble are very neutral in tuning. There was no circumstance that the Xuan NV shouted at me unless recorded in the music; the upper midrange was tuned on the safe side, but it never sounded boring. It sounds consistently energetic across the audio range. The Xuan NV sounds very coherent from low volume to high volume levels. There were no signs that the sound was being produced by two different drivers; it's as if they speak as one.

One thing that is also worth mentioning is that the Xuan NV sounds open, unlike some budget hybrids and dual dynamic driver sets I've heard that sounded a little congested and lacked dynamics.

Resolution and details:

The Xuan NV has enough resolving power to make you enjoy the details in the music, but not so much that it sounds analytical. It never pushes the details in your face; it has a soft-handed presentation of the details, but when you search for them, they are there. It also has a fair amount of fine micro-details, but not so much that they call your attention, just enough to make the sound naturally enjoyable.
.
Soundstage, imaging, and holography:

It sounds spacious and never claustrophobic; the vocals are never in your face; and the imaging and holography are good but average for the price.



Bass:

This is the best part of the Xuan NV; it's the best boosted bass I've heard, but take this with a grain of salt as I haven't heard all the bass-boosted IEMs available. The bass, though boosted, doesn't sound overbearing; it sounds fast and very coherent with the rest of the music; there is no sensation that it is getting left behind by the speed of the midrange and treble; it sounds very musical and energetic. I am confident to say that even neutral-head audiophiles who are looking for a bassy set as a variety would be very pleased with the bass that's in the TangZu x HBB Xuan NV.

On the song "Jessie Ware - 12 [Demo]" (please search YouTube), the bass sounds very pleasantly accompanying the vocals and keeping up with the rest of the music.

On the song "Take This Love by Sergio Mendez" (please search YouTube), the timing of the bass drum and bass guitar is very tight, and the bass has a very pleasant depth and growly texture. I've never heard this song's bass section sound this good.

Midrange:

Warmish-neutral and lush sounding; smooth and non-fatiguing; there are no frequencies that jump out at you; the upper midrange is a little laid back; and when it comes to vocals, it tends to favor the male vocals just a little more than the female vocals.

Treble:

Surprisingly refined and delicate, it sounds as if you are listening to a more expensive set. Very smooth yet energetic, with a good amount of macro details, micro details, air, and sparkle. The upper treble extension seems to be very finely tuned, as it's neither too much nor too little; it's just the right amount for my taste. There is no harshness in the highs; it is totally non-fatiguing.

Comparisons:

Compared to QKZ x HBB Khan (40 USD):

The QKZ x HBB Khan, released in the year 2022, is a collaboration product of HBB and QKZ. The Khan has a good and clean subwoofer-like sounding bass, but when it comes to the midrange and treble, there's no contest; the Xuan NX absolutely obliterates the Khan. The Khan has a thin midrange note weight and a less refined-sounding treble that can sound fatiguing at times.

Compared to Simgot EA500 (65 USD):

The Simgot EA500 has been, for a long time, a benchmark in sound quality in the 60- to 100-dollar price range. It is now supplanted by a newer version called the EA500LM.

The EA500 has a thin note weight and sounds tiring in long listening sessions because of it. The EA500 has a more forward presentation and also has good amounts of details, but it has a flat soundstage, meaning the instruments and vocals all seem to come from a space near you in a flat manner. It lacks three dimensionality, not like the Xuan NV which sounds more holographic by comparison and never fatiguing as it has a thicker note weight and a smother overall presentation.

Compared to Moondrop May (60 USD):

Using a third-party cable and not the DSP cable that it came with, the May is my previous top contender in the 60 to 100 dollar category; it is now surpassed by the TangZu x HBB Xuan NV. The May has a very tasteful sub-bass boost, a mildly recessed midrange, and a very articulate sounding treble due to its planar treble driver that operates at 8 KHz and above. The only obvious fault of the May in my opinion, is the lack of cohesion between its dynamic and planar drivers. I can hear some incoherency in the treble, but even so, the sound of the May is very good, and it is still on my recommended list in its price range.

Compared to QKZ x HBB Hades (50 USD):

The Hades is a recent collaboration product between HBB and QKZ. The Hades is a straight-out bass-head IEM, and the bass is so loud that it drowns out the midrange and treble. When it comes to sound quality, the Xuan NV has much better-sounding bass and overall sound quality in general. I can't personally recommend the Hades; just go with the Xuan NV insteads.



What I like:
.
+ the bass.
+ the design and color.
+ the overall good sound.
+ the price.
+ the eartips.


What I don't like:

- for the price, none.

The wrap-up:

I was pleasantly surprised about how good the TangZu x HBB Xuan NV sounded the first time I listened to it, and I'm still reveling about it now after a week. This is an excellent value for money, and to be honest, if I weren't a reviewer and just a regular audiophile looking for an IEM on this budget and magically knew what I knew now, I would just buy the Xuan NV and just enjoy the music. Needless to say, I wholeheartedly recommend the TangZu x HBB Xuan NV to my friends and everyone. Cheers!

This collaboration between Tangzu Audio and the revered reviewer HBB promises an experience as captivating as its name, The Xuan NV, which translates to "mysterious woman" in Chinese, promises an intriguing soundscape. But will it live up to the hype? Linsoul kindly sent this IEM my way for an honest review, and I'm eager to dissect its every aspect – from design and comfort to, most importantly, the soundscape HBB has helped craft.

UNBOXING:

Upon receiving the Tangzu x HBB Xuan NV in the mail, the first thing that caught my eye was the stunning artwork adorning the box, featuring captivating waifu illustrations and yes i like waifu and It sets the tone for what's to come—a blend of artistry and craftsmanship and some HBB love.

Opening the box reveals a black soft leather pouch, It's a thoughtful inclusion for safely storing your iem but the real surprise are the two sets of balance and wide bore Tang Sancai tips nestled within the packaging. These tips when bought separately cost 12usd per set.

Moving on to the IEM itself, the shell immediately commands attention with its striking bright blood-red hue, exuding elegance and sophistication. The gold-painted graphic art on the face plates further enhances its aesthetic appeal, the black cable however feels cheap and has a sticky rubber like material which remineds me of my old kz zst cable but not a deal breaker i just replaced with my 4.4 balance cable.

FIT and DESIGN:

• The Tangzu x HBB Xuan NV IEM fits like a glove, providing a snug and secure fit that ensures comfort during extended listening sessions. Its ergonomic design contours to the shape of my ear, minimizing any discomfort or strain. The shape allows them to sit flush against my ears without causing any pressure points. Overall, the fit of the Xuan NV enhances my listening experience by providing stability, comfort and a good seal.
• 3D Printed Resin Shells: The Xuan NV utilizes lightweight and comfortable 3D printed resin shells. They come in a sleek red finish with gold artwork are visually appealing.

DRIVER:

Ceramic drivers are known for their high sensitivity and low impedance, which means they can produce ample sound output with relatively low power input. This makes ceramic driver IEMs generally easy to drive however, while ceramic driver IEMs may be easy to drive, they can still benefit from higher-quality amplification for optimal performance.

PU, known for its flexibility and damping properties, provides the foundation for the dynamic driver. Its ability to absorb unwanted vibrations helps minimize distortion and coloration, resulting in cleaner and more accurate sound reproduction. Additionally, PU dynamic drivers often excel in reproducing mid-range frequencies with warmth and richness, making them well-suited for vocals and instrumentals.

On the other hand, LCP is renowned for its exceptional stiffness and strength-to-weight ratio. This allows LCP dynamic drivers to produce highly detailed and articulate sound. LCP's rigidity enables faster transient response and reduced resonance, resulting in improved clarity and resolution, particularly in the high-frequency range.

By combining PU and LCP dynamic drivers in the Xuan NV, most likely Tangzu audio aim to leverage the complementary strengths of both materials to achieve a balanced sound signature. The PU driver provides a solid foundation for the mid-range frequencies, delivering warmth and body to vocals and instruments, while the LCP driver adds clarity, detail, and precision to the overall sound presentation, especially in the treble region.

The dual dynamic driver configuration of the Tangzu x HBB Xuan NV IEM combining two distinct driver to deliver a balance audio experience with the help of a little amplification, its not hard to drive but to fully enjoy a dynamic sound of this iem a simple dongle dac amp will open it up to its full potential.


SOUND:


Bass:

One of the most impressive aspects of the Tangzu X HBB IEM is its clean and rich bass response. the Xuan NV delivers a bass that strikes a perfect balance between warmth and clarity. Sub bass rumble is strong but well controlled The mid bass is smooth, unintrusive, and maintains remarkable clarity and energy even in bass-heavy tracks. Whether you're listening to bass-shy tunes or 90s alternative rock anthems, the Xuan NV bass adds a layer of depth and richness without overshadowing other frequencies.

Mids:


The midrange of Xuan NV is the best part where i think it truly shines, offering a sweet and smooth thick sound signature that is captivating and immersive. Instruments and vocals are presented with a warm, rich, thick velvet like smoothness. Vocal clarity is superb, pristine and well-layered. Vocals sound so natural with warmth you can almost feel, the mids have weight, thick but not dark sounding. Male and female vocals are represented accurately without adding color.

Treble:

The treble of the Xuan NV is characterized by its inoffensive nature, lacking any harsh peaks or excessive emphasis. While it may not satisfy treble enthusiasts seeking heightened energy, its soft and smooth presentation makes it ideal for extended listening sessions. The treble energy is gentle and still manages to sound airy which adds to clarity and a sense of widened space and overall providing a relaxed listening experience without causing fatigue over time.


Technical Performace and Sound Signature:

• Warm Neutral with a U-Shaped Tilt: The Xuan NV strikes a delightful balance between warmth and neutrality. Bass is present and rich, adding a satisfying foundation to your music without overwhelming the mids. Vocals take center stage, presented smoothly and intimately. Treble is relaxed and inoffensive, avoiding harshness but maintaining enough sparkle to keep things interesting. This U-shaped tuning creates a very listenable and forgiving sound signature, perfect for extended listening sessions.

• Timbre and Tone: This is where the Xuan NV truly shines. Instruments and vocals have a natural and realistic quality, thanks to the excellent timbre and tonal balance. Guitars sound full-bodied, drums have satisfying impact, and strings have a smooth, articulate character. Vocals are a particular highlight, rendered with thick, warmth and clarity.

• Technical Performance: While not the most analytical IEM on the market, the Xuan NV offers a good level of detail retrieval for the price. It won't reveal every nuance of complex recordings, but it provides enough clarity to keep you engaged with the music. Soundstage isn't the widest, but imaging remains decent, allowing you to distinguish the placement of instruments within the mix.

Who is this for?

• Listeners who prefer a warm and musical sound signature.

• Vocal lovers: The smooth mids make vocals a real treat.

• Budget-minded audiophiles looking for great sound without breaking the bank.

• Those who find overly analytical IEMs fatiguing.

Things to Consider:

• If you crave a super detailed and analytical sound, the Xuan NV might not be your best bet.

• The bass, while present, might not satisfy extreme bassheads.

CONCLUSION:

Overall, the Tangzu X HBB IEM offers a compelling blend of design, sound quality, and technical performance at an accessible price point. The collaboration between Tangzu Audio and HawaiiBadboy (HBB) results in a finely-tuned, well balance and musical sound signature that strikes a good balance between audiophile performance and mass appeal with its clean bass, silky midrange, and smooth treble, it provides an immersive listening experience suitable for a wide range of music genres unlike my other fave hbb collab Xuan NVs alter-ego of sorts the Hades which shines and caters to a specific genre of music. In conclusion Xuan NV represents excellent value for listeners and enthusiasts who likes overall musicality and with the striking red with gold aesthetics this stand out in a crowded market by offering exceptional value and performance that appeal to both audiophiles and everyday music lovers.

**Disclaimer:** The Tangzu x HBB Xuan NV IEMs were provided to me by Linsoul Audio for the purpose of this review. I did not receive any compensation for my comments and the opinions expressed here are solely my own based on my personal experience with the product. This review is meant to offer an honest and unbiased impression to help potential buyers make an informed decision.

General Information (Build/Packaging/Comfort)
Xuan Nv is a collaboration between Tangzu and HBB if you don’t already know. It is a dual dynamic driver config where the 10mm dynamic driver and 8mm driver
Xuan Nv got a very beautiful faceplate. It's 3D printed and the unit is very light and I don't feel the weight on me when I'm wearing them. The packaging is the usual Tangzu’s styled packaging. Within the box, you have the IEM itself, two types of Tangzu’s eartips, the balanced and the wide, i personally preferred the wide tips with Xuan Nv, we will get to that later. So you are spoiled with choice in terms of eartips, the balanced and wide also affects the tuning so feel free to try out and see which is your preference

Gears used for this review

• Cayin N3 Ultra
• Hiby FC6
• Fiio K9 AKM
• Tangzu x HBB Xuan Nv with Sancai Wide Eartip

Foreword
My review is solely based on what I hear via my equipment and I never consider my reviews to be objective in any way rather a subjective approach. Do take into consideration that everyone’s ear anatomy is not the same, so the psychoacoustics perception might be different as well, but i believe it will not stray too far


Sound Impression (with Wide eartips)
To my surprise, the Xuan NV, despite bearing HBB’s collab badge, doesn't sound like the usual HBB”s tuning that I have heard of, especially on the bass region. Tonality wise, the Xuan Nv is a warmish set and sub bass focused, i would say, it is a very safe set overall

Bass

• It is not a bassy set like one of the collab, Hades, rather the bass has quite good control when it is properly powered
• Sub bass does rumble when the track calls for it, not bass head kind of rumble but sufficient in terms of quantity for it to be fun
• Mid bass does lack a little punch, which is why i’m surprised as HBB’s collab usually have punchy mid bass
• Not the best in terms of control and texture, but for the asking price, i think it is fair
• Bass is speedy enough to handle complex track, but there are also times where it fall shorts (Metallica’s Lux Aeterna)

Mids

• The mids are slightly recessed and retains a little warmth from the lower region that was carried over
• Vocal positioning are neither too intimate nor recessed
• Male vocal has good enough texture, female vocal has sufficient energy, but might be lacking for females with higher vocal range

Treble

• The treble response is smooth and non sibilant, a very safe approach and I'm sure even the treble sensitive guys/girls will be able to handle it
• While it’s good to have a safe approach, it also kills off some air which is evident on some busy tracks where everything will sound a little like “mashed” with each other. This is just me nitpicking, and of course something's got to give
• Detail retrieval is good enough for the price. Definitely not for critical listening
• A very smooth set overall

Soundstage/Imaging

• Soundstage is slightly out of the head but lacking a little height and depth to my ears. Imaging is average
• instruments can be picked up easily but of course it struggles a little on busy tracks.

Driveability

• This Xuan Nv, loves power, in fact if you fed it when some source which doesn’t have sufficient power, the bass sounds very uncontrolled or muddy at times, lacking dynamics as well, once again, i have to re-iterate, volume does not mean/equivalent to driving power
• Hiby FC6 for example, works well with the Xuan Nv, depending on your preference, i prefers the Xuan Nv to have a slightly cleaner sound, hence pairing it with Fiio’s K9 AKM works for me

Comparison (Dunu Titan S)

• Bass is definitely not the strong point of Titan S, lacking in terms of quantity, but compensated with quality bass (fast and tight)
• Vocal is more prominent on the Titan S but also having a little more energy on the upper mids, this might be a little problematic for some people who are sensitive at this range
• In term of treble, Titan S has got a bit more energy and air but nowhere near offensive sounding or harsh
• Detail retrieval on Titan S is slightly better
• Soundstage and Imaging is slightly better on the Xuan Nv
• I made it sound like Titan S is a better choice, isn't it? It is not, well, i’d say Titan S is focusing more on technical performance while Xuan Nv is easy going and fun. To me, the target audience is different.

Final Thoughts
All in all, the Xuan Nv is a smooth and fun set that’s targeted at those who want to just plug in and listen to their music without going into a critical listening session. The Xuan Nv does everything alright and to be honest, if you already owned something similar in this price range or similar configuration, this is a sidegrade for you, but if you’re looking for some fun and smooth set and you don’t own anything with similar sound signature, by all means, get it, considering the asking price and also two types of eartips bundled, the price performance ratio is actually quite high.
