NiceHCK, a brand that is primarily known for their cables and not so much for their IEMs but that cannot be said the same for their flat earbuds which had always been popular, even when I first started my journey into the hobby back in 2019. In fact, they had a great success with the release of their earbuds such as the NiceHCK B40, EB2S which in recent times has relished an update to the EB2S Pro and last but not least the flagship NiceHCK EBX25Ti. Famously worn by a Japanese video game icon Hideo Kojima, also known as the man behind the Metal Gear franchise.
In my review this time however, I’ll review their latest flat earbud release, the NiceHCK B80 which features a 14.8mm dynamic driver with a special diaphragm which NiceHCK refer to as PU TopologyBio Diaphragm. This earbud retails starting from $32.99 for a basic 3.5mm plug without an inline-mic, all the way up to $37.99 which you’ll get the NiceHCK B80 available in 4.4mm balanced plug. With all of the pleasantries done, let us jump into the review!
Unboxing Experience
When we’re in the context of audio products, the first thing that always comes to mind when we expect what to see on the box would be an illustration or 3D rendering of the product itself. But this is not the case with the NiceHCK B80. Instead, a female waifu in white dress is the first thing you’ll see followed by the NiceHCK brand and earbud model. As you inspect a bit closer then you’d realize the waifu actually had the NiceHCK B80 worn on her ears. On the sides of the box, are printed with the name of the earbud and selected plug options. Meanwhile, on the back is printed the specifications for the B80 alongside some details and information in regards to the company and their contacts.
As we open the box, we’ll be greeted with the same waifu except this time it was a display card measured at 13.5 cm in length and 9.4 cm tall with a photo of her printed on glossy paper.
Nevertheless, as we explore further there’s a standard NiceHCK fabric hard case which contains the earbuds, alongside a NiceHCK branded cable organizer and two packs of foam respectively a donut foam and a full foam cover. Last but not least, there are also some paperworks, manual guides and warranty cards included at the bottom of the box.
The NiceHCK B80 chassis is made using the same body taken from the YUIN PK2 which was popular and often regarded as comfortable among the flat earbud community. Despite only being available in black, NiceHCK has gone for a glossy paint finish on the body of the B80 with some glitters which looks absolutely stunning when shone under natural lights. Additionally, there are indicators for left and right channels for the earbuds which are printed clearly just below the stem of the body.
Overall, the ergonomics of the earbud were great if you allow it to naturally sit on the conchae of your ear. That said, I’m not a big fan of earbuds generally due to the shape but with the B80 I will usually be able to wear the earbud for a good 1-2 hours before needing a break to relieve the pressure point on my ear. The provided foams are soft and comfortable to wear without causing any skin irritations.
Cable
Being a brand that specializes in cables, NiceHCK did not skip when it comes to the cable for the B80. Truth be told, it puts some cable from their IEM cousins to absolute shame, thankfully enough these two don't belong in the same category or it might've put some names to shame.
Based on the specifications provided by NiceHCK, the cable on B80 features a 2 core, OFC cable + silver-plated OFC cable measured at a roughly 1 meter in length. The aesthetics on the cable was absolutely stunning with its thick polyurethane (PU) shielding which is coloured in black and decorated with gold flakes to increase the visual appeal, meanwhile the plug and Y-splitter is made using metal with the same glossy finish on the earbud. In terms of ergonomics however, the cable was a bit on the stiffer side but still very much manageable and easy to be wrapped for storage. Microphonics are absent during usage when the cable rubs against coarse fabric or rough surfaces. Like I said in the introduction, there are multiple options of termination and cable available for the B80, such as the 3.5mm plug without an inline-mic, a 3.5mm with inline-mic and a 4.4mm balanced without an inline-mic.

Power Requirements
The NiceHCK B80 rated at 20 Ohms with a driver sensitivity of 114 dB/SPL, makes the earbud efficient and scales very much easily across various sources in my collection. From small dongles all the way to powerful handheld devices, I was able to power the NiceHCK B80 absolutely fine without any problems. Such as the Kiwi Ears Allegro Mini which is considerably a weak small dongle, feeded through my Sony Xperia 1 V. I was able to reach my comfortable listening volume by cranking up the volume to 4-5/30. Meanwhile, on something more powerful such as the Astell&Kern SE100, I only needed to raise the volume wheel up between 35-38/150 to reach my comfortable listening volume. Hence, powering this earbud won’t be a hitch for most people even if you only have an Apple dongle in your arsenal.
Sound Evaluation
The NiceHCK B80 has undergone burn-in phase for at least 48 hours prior to sound evaluation. Throughout the analysis, I paired up the B80 with a neutral source, the A&K SE100 on Linear Phase Fast Roll-off Filter chosen given that it’s the most natural sounding filter compared to default. The provided donut foams are used as default throughout the sound evaluation. Bonus test tracks used can be found down at the end of this review.

Diagram 1.0: Frequency response of the NiceHCK B80 with various foams included in the package. Also the courtesy of Young DB.
NiceHCK has gone for a neutral-warm sort of tuning for the B80 which primarily focuses on the midrange and higher frequencies which can be seen through the frequency response graph. Bass frequencies were less dominant on the B80 due to the roll-off at mid-bass, thus other qualities in the lower-bass area such as sub-bass and rumbles will not stand out as much.
Nevertheless, it does still provide a pleasant warm tint into the midrange and bass punchy bass slams to satisfy your groovy soul. The mids were presented in an upfront forward manner with a smooth, effortless quality despite the accentuated ear gain peak. Treble on the other hand, has a smooth and mellow tone with just enough emphasis for such related elements present in your music rather than gushing large amounts of details and resolution.
Low Frequency (Bass)
Typically with most earbuds due to its design often resulting the bass frequencies being the less dominant feature and that is no difference with the NiceHCK B80. As a result, sub-bass is barely audible especially at the lowest octave when tested through my usual tracks such as Hollow (16 Bit Remix) - Björk, that being said by swapping to full foam and silicone covers does help slightly albeit the difference was subtle.
Mid-bass on the NiceHCK B80 I would describe it as slightly north to neutral, clean, punchy with good responsiveness delivering bass slams rapidly. While it won’t satisfy those who crave those thick bass. The bass impact produced by the large 14.8mm dynamic driver still delivers a slam that resembles a solid “thud” with decent heft with each bass punch. The N52 neodymium magnets used in the driver provide good fast response allowing the B80 to catch up with tracks that have high tempos such as Hunter - Björk without any feeling of sluggishness or causing melding during the process. However, I do hear the bass on the B80 tend to sound slightly hollow. Take it as you’re slapping a thick double corrugated cardboard in with certain elements such as in drums, the sound of a drummer hitting the snares and toms is what I would describe it.
Middle Frequency (Mid)
Midrange is the key strength for the NiceHCK B80, characterized by its forward and smooth presentation which sounded natural and organic. Overall timbre of the midrange is neutral with a slight colouration which gives vocals and stringed instruments a slight warm tone. However, it lacks note weight and definition hence deep or grungy male vocals won't be as thick or textured as one might anticipate. Upper-mids appear to be safe on the B80 even for someone that is sensitive to accentuated ear gain, plus it can be further reduced by using the full foam. Albeit, it does make the B80 sound a tad more recessed for my liking.
High Frequency (Treble)
Laid-back, butter smooth are the words best to describe the treble on the NiceHCK B80. Although the treble presence is not that strong and lively, while some might consider it dark. Nevertheless, the tuning for the treble does make everything sound very pleasant, tolerable even for those who are sensitive and furthermore overpower the other frequencies. However, the smooth tuning does lead to the B80 sounding a tad splashy, perhaps if the treble was slightly more crisp then it would've been perfect for me.
Additionally, the B80 does not accentuate sibilant notes when played through sibilant tracks such as Underwater Love - Soulperfreesia despite the slight peak at 5kHz. That said, I'm particularly impressed with the treble extension on the B80 as it adds air and reduces the speed of transients. Allowing the subtle notes in the treble region to linger slightly longer before it gradually fades. Such as high notes produced by a violin or the tail coming from hi-hats and crashes after being hit.
Technicality
First thing that I immediately noticed on the NiceHCK B80 was the large soundstage that this earbud could render. Albeit it was not immersive or holographic as I would want, the B80 still has a great sense of width from both front/back and left/right as well. Spatial imaging (localization) was between decent and mediocre in my opinion, while it does well rendering sound coming from cardinal directions. I find the B80 struggles to render sound coming from intermediate directions and pinpointing how far was the object/element.
Detail retrieval was average in my book, the B80 does pick up high-level details quite easily but it does fall short when rendering low-level details, subtle nuances in tracks or when used for gaming. However, in terms of resolution the B80 was able to score only up to mediocre based on my testing. For example, the creaking sound at the background in Motherboard - Daft Punk has a subtle, groovy texture that follows the sound, which was absent through the B80. Layering and separation was average as well, the B80 can get congested and cause melding when played with busy tracks. Plus, despite the huge soundstage the B80 can't make use of it due to the poor layering since most of the elements in tracks are placed in a single spot rather than individually spaced out from each other.
Lastly, the dynamic range test for the NiceHCK B80 is rated at average. Utilizing the Ultimate Headphone Test - ABYSS Headphone dynamic range test as a reference. In short, a sample sound of a drum and a bell are played simultaneously as much as 7 counts, but only the sound of the bells will become quieter. Hence, from a scale of 7 counts, the B80 was able to produce an audible 5 out of 7 counts.
Comparison(s)
Due to my lack of knowledge in flat earbuds, I was not able to provide any comparisons with other earbuds in the market. Deepest apologies for any inconvenience caused and to those who might be interested to know how does the B80 perform against other earbud models within the same price category.
To conclude the review, NiceHCK has made a flat earbud that is not only visually appealing but it sure does deliver a pleasant sound as well. Despite some shortcomings mainly in regards to the technicalities, I thoroughly enjoyed the sort of tuning presented by the B80 and this flat earbud has been a regular addition into my rotation list across various source in my collection. Although that being said, my interest is more towards IEMs and headphones.
The familiar build of the PK2 which is utilized for the B80 does allow audiophiles to be confident that this earbud would present a similar feel and comfort that they recognize with any other flat earbuds in the market. Hence, whether you're a veteran or a newcomer to flat earbuds and wish to try a mid-centric sound signature that focuses on delivering pure musical experience then you might want to check out the NiceHCK B80. Nevertheless, I hope you all enjoyed the review for the NiceHCK B80, thus that marks the end and I'll be seeing you in my next review!

#NiceHCKB80
Nicehck B80: Turns out it's delicious...
Intro
First of all, I would like to thank NiceHCK Audio for sending this Nicehck B80 unit for review.
For this review I used the FIIO KA15 source with a volume of around 50% on the 4.4mm BAL plug, because I happened to get a unit with the 4.4mm Jack version.
Completeness
For completeness, the Nicehck B80 gets the following parts:
The housing build for the B80 earbuds is made from resin with a finish that makes me look neat & attractive in appearance. Namely a black color that is slightly transparent with additional sprinkles such as golden yellow grains which make it look premium.
The cable is also quite good with the cable size being just right plus the finishing is similar to the expensive cables I have reviewed before in black + there are a few sprinkles of golden yellow grains too so it looks good & has a slight premium feel. The cable is also still relatively flexible & can be rolled up neatly. As for the jack & splitter, it's still quite okay, it doesn't seem cheap, although it's not really good either.
As for the fitting, it should be comfortable for many people, because it uses a smaller housing like the Yuin earbuds plus the material is also made of resin. So it's nice to wear for a long time and doesn't make you sick or sore like earbuds with a normal shape in general.
Bass
These Nicehck B80 earbuds have just enough bass with the sub-bass extension which is also just enough or not too deep. The midbass isn't the best either & the texture isn't that good either.
The only good thing is that the bass is typically clean, has good speed & has good control too. So for fast songs the B80 bass is better than for songs that require big bass or boom.
Mid
Well, the most interesting part of the B80 is in the mids for me, especially the vocals. This B80 has mids that are quite forward but not too forward and the weight is just right. Not thick but not too thin either.
The vocals themselves are a little more pleasant for female vocals. To be honest, the guy's vocals are a bit thick, but for me I can still enjoy the guy's vocals. Meanwhile, the female vocals are quite good with a clear, energetic, sweet & minimal sibilance or shouty vocal presentation.
Treble
As for the treble, the B80 is still in the smooth treble category or not the typical sparkling, very energetic or aggressive treble. Even though the treble is smooth, the presentation for me is still quite good. The impression of detail, the crispness of the treble is still delicious.
The treble extension is also quite good, the airy & open impression of the treble is still felt well. The most important thing is that there is no sharp impression or strange peaks so the treble is pleasant to enjoy for a long time.
Technical
Technically, this is also a good one for me. The details are good, the separation & positioning are also neat, the clarity is also okay, the transients are also good, the timbre is also natural & the soundstage is also spacious. Maybe the only thing that's lacking for me is the depth, which still feels sufficient so that the imaging still feels 2D.
Comparison
Nicehck B80 VS DailyMusik V3:
By memory, the V3 has even thinner tonal weight, both bass, vocals and treble. The most noticeable thing is that the treble is more sparkling, more energetic or has a wider treble than the B80. The technique is also better in detail & transient speed. Make Metalan V3 even better. It's just that the B80 is still good for metal, but it's not as fun as the V3. Otherwise, the B80 feels better, especially in many genres, especially for vocals.
Conclusion
Nicehck B80 are the newest earbuds from Nicehck which sell for around $33-$37. For the price, what I got makes me very satisfied. From good packaging, complete packaging, good build quality, both earbuds and cables & also the sound presentation which is quite good, although not perfect because there are still shortcomings in several aspects. But for me the lack of it is still at an acceptable or tolerable level.
Yes, in conclusion, for the price, it's a must try, especially for those who want to move from IEM or just want to refresh from IEM, hehehe.
Yes, that's all my review of the Nicehck B80.
Thank You.
Regards.

Pros: Great bass, reminiscent of an IEMS.
- Remarkable sense of openness, facilitating a wide and surrounding scene.
- Good cable, best choice of 4.4mm balanced plug.
Cons: The very smooth surface of the capsules causes the foams to slip and come off.
- Although the cable is good and thick, it can be a bit stiff.
Introduction
NiceHCK is an Aliexpress shop known for its audio products. It is an expert in cables and accessories, as well as IEMS and, of course, headphones. And continuing with its B series (B40 and B70), now comes the NiceHCK B80, headphones that still feature the classic small PK capsule, this time with a 14.8 mm dynamic driver with a diaphragm that combines biomaterials with PU and a topological design to reduce distortion from the vibrations of the diaphragm itself. N52 high-performance magnets. They use an OFC cable mixed with silver-plated OFC and three plug options: 3.5mm SE, 3.5mm SE with microphone and the expected 4.4mm BAL plug. The B80s have been handcrafted with black baked-on paint and are powder-coated with gold dust on the surface, even the cable has traces of gold dust on its sleeve. The anime girl on the cover and the brand's signature good accessories remain, of course. Let's dive deeper into its content, sound and other issues in this review.
Specifications
Driver Type: Dynamic with 14.8mm TopologyBio PU diaphragm.
Frequency Response: 20Hz-20kHz.
Sensitivity: 114db/mW.
Impedance: 20Ω.
Jack connector: choice of SE 3.5mm, SE 3.5mm + mic, BAL 4.4mm.
Cable material: OFC + Silver Plated OFC.

Packaging
NiceHCK are presented in a medium-sized, horizontal box measuring 148 x 107 x 41 mm. NiceHCK continues to illustrate the boxes with an anime girl. On the top left is the brand logo and on the right the model and a product description in brown lettering. On the back are the product specifications, the brand's contact details and other details. The outer cardboard slides horizontally to reveal a black box with interlocking circular lines in glossy black. In the centre, the model name can be read in white letters. Lifting the lid, we find a card with the anime girl of the box in a silver frame. Underneath is the brand's classic zipped case in light grey with a fabric surface. Inside is the product and various accessories. In brief, the complete contents are as follows:
NiceHCK B80 earbuds with 4.4mm BAL cable.
One zipped case.
Three pairs of full black foam earbuds.
Three pairs of black foam donuts.
Velcro strip for cable management.
User's guide.
Warranty certificate card.
Card with links to social networks.
The headphones are packaged in a clear plastic zipped pouch. The 4.4mm connector is protected by a custom plastic sleeve. The foams come in sealed white plastic bags. The zippered case is the usual branded case, very good and appropriate. Six pairs of foams of both types are fine. The foams are of decent quality.
Construction and Design
There is not much to say about the design of the B80s, as they use the classic PK capsule, one of my favourites for its great comfort. The difference between the two models is usually in the rim, which is a bit thick and rounded. In this case, the rim is flat. NiceHCK wanted to highlight the model and, to do so, they have handmade it using black baked paint. In addition, they are coated with gold powder all over, even the cable has traces of gold powder on its black PVC sheath. The capsules have two horizontal openings at the back and a grey lettering indicating the channel near the cable outlet. The cable is black, has two coiled strands and has traces of gold dots on its surface. The plug sleeve is a metal cylinder coated with the gold dust, with the brand name inscribed lengthwise in white letters. The cable outlet is secured by a small rubber cylinder of the same colour. The 4.4mm BAL plug is gold-plated. The splitter piece is the same, a smaller gold powder coated metal cylinder, I would say half the size. The pin is identical, but about one third the size of the divider piece. It has a plastic inner part with a figure-eight hole through which the two wires pass. Although the sliding is smooth, it is also firm when it comes to securing the fit.
As I say, the shape of the capsule is the classic PK with NiceHCK sprinkling a bit of ‘gold’ on the surface. The cable seems to be good and the plug sleeves are of superior quality. One of the things I appreciate the most is the option to choose a 4.4mm balanced plug. Bravo!
Adjustment and Ergonomics
The PK capsule is one of my favourite capsules in terms of fit and ergonomics. Its small diameter and thin spike are a design achievement, combining minimalism, simplicity and practicality. In this case, the thickness of the lid is the only thing that could limit the comfort of these capsules.
The cable is another point that may influence the overall comfort of the set. It consists of two coiled strands of a certain thickness, which have a slight stiffness. Perhaps this is the only critical point, it is a good cable that can become stiffer over time.
Sound
Profile
It's been over a year since I've tried new earbuds and it can be a surprise to hear a new model again. They say it's the first impressions that matter. When I tried the new NiceHCK, I was surprised by the power and cleanness of the bass. And, of course, the openness and richness of their sound. The NiceHCK B80s are warm, dense and smooth on top, but with enough clarity to appreciate good separation, which bodes well for a wide stage and powerful sound. The B80s make me believe that the loudness of the earbuds is close to that of the IEMS, and without feeling that full contact inside the canal that gives them that sensory advantage.
Bass
Bass is always tricky in earbuds, but the B80s impart a sense of presence, punch, energy and power without sounding dark or sluggish. Bass is much more technical than you'd expect from such a small, open, space-constrained capsule. The very low frequency pure tone test is usually not appropriate for this type of headphone and demonstrates some physical limitations of the PK capsule in reproducing very low frequency continuous bass. However, the B80s tolerate a remarkable level of energy and are able to reproduce LFO from 30 Hz onwards in a very realistic and natural way. Below this value, the behaviour is more vibratory and audible than sensory. Nevertheless, I find it quite satisfactory. But the most surprising thing is that above 30 Hz, the tones are audible, clearly discernible and powerful. Admittedly, there is some subtle colouration, but it is compensated by the remarkable physical sensation they give off. Thus, the result is a very accomplished low-end, with strength and physicality, and a presence that does not muddy the rest of the sound.
The very dirty, unfiltered bass test is perhaps the most complex test for headphones. But even here, the B80s have shown control in keeping bass in check, avoiding the distortion, vibration and reverberation that their small capsules could produce. In this way, the B80s demonstrate control, discipline and the ability to follow difficult bass lines without being facile or simplistic, generating a good level of texture, retrieval and moderate punch despite the level of power on display. They are very enjoyable.
Mids
It is true that the PK capsule has some endemic shortcomings, such as its propensity to have a somewhat muddy first half. And it's true that the B80s don't try to avoid that feeling altogether. What is true is that their sound is clearer and more open to compensate for this perception. Thus, the first part of the mids feels dense, although it does not totally dominate. The male vocals have a large base, but they get thinner as the frequencies increase. In this way, the sensation is that of a firm substratum that thins and dilutes until it ends in a sweeter, finer and more delicate way. Thus, male voices do not feel completely dense or impenetrable, but more graceful and detailed, maintaining a good level of warmth and body. However, unlike the voices, the lower strings can experience this impression that clouds them and shifts them to a less natural level of projection. In this respect, one misses a little more finesse in the tuning of this first half.
Female vocals are perceived as warm and maintain that characteristic body and thickness of these capsules. But it's worth noting that the sense of separation and openness greatly decongests the sound, giving it the necessary, even life-saving, amount of air. In this way, larger and more spacious mids are appreciated, with a superior facility for showing detail, without the notes ending up thin, but rather average.
Finally, the upper mids are controlled, there is a point of excitement that attracts cleanliness and clarity. But it is a softened profile at that point. Even so, there remains a glimmer of transparency, clarity and liveliness that brightens the sound within the projection of the mids.
Treble
The first treble has two flares and a marked control zone. In this way, a double expression is created: a more highlighted base and a later flare joined by a central softness. It is like a spark and a flash, two small controlled flashes. Admittedly, this may be commonplace, but in this case that sensation seems more apparent, so that controlled but sparkling treble is achieved.
There is a slight air fringe as the extension weakens after that point.
Soundstage, Separation
The strong point is the sense of openness, the scenery is wide and open, there is great laterality and it is accompanied by a gaseous, volatile and enveloping point. The level of definition and detail is somewhat more complex. The good feeling of openness and separation favours the detection of macro detail. The lack of density and finer sparkle and thinner notes prevents micro-detail from being more evident. The use of doughnut-type foams can enhance the perception of the tiniest detail, but I feel that the level of resolution is tight. A little more layering capability and a cleaner, sharper, more evident background is lacking.
Comparisons
ISN Rambo
Almost five years have passed between the two models. Both are the same in design, same PK capsule with the same cover, but the surface of the B80s is polished, while that of the ISN Rambo is microrough. The cable is different: thick, two-stranded black PVC-coated cable on the B80s, and four thin silver wires on the Rambo. The Rambo's cable is more flexible and manageable, but feels a little thin and delicate when it splits in two towards the capsules. The metal parts of the cable are small and flashy on the ISNs, while on the B80s they are large, regular and gold-plated, more solid and heavy. I like the minimalism of the Rambo. As for the accessories, both are very similar: both have zippered cases and six pairs of full foams. The difference is that the B80s have three pairs of full foams and three pairs of donuts. The ISNs come with a small carabiner and a black plastic clip. The starting price of the B80 is $33, while the Rambo was $65 and can still be found for $49.
Although the glossy, satin-finish surface of the B80s is the same, their fit is slippery. In contrast, the Rambo's fit better and are more secure thanks to their micro-texture.
For the audio tests I used the same full foams that came with the B80s. The Rambo's are harder to move than the B80s. They also sound muddier and more distant, with less clarity and brightness.
In the low end, the excellent improvement in bass reproduction of the new B80s is noticeable. Bass sounds with authority, presence, power, realism, depth, darkness and naturalness. You can even feel the sub-bass. In contrast, the Rambo's bass is rather coloured, less natural sounding, displaced, there is no sense of sub-bass and it vibrates less realistically. The only advantage is that their punch is drier, but their sonority and behaviour are unnatural. The great virtue of the B80s is that their low end is reminiscent of an IEMS, which is very surprising.
In the midrange, the lack of bass makes the first half of the midrange feel more sterile, less physical and more nasal in the Rambo. There is a noticeable hollowness in this area, creating a comparative gap between the two models. The sound of the B80s is much fuller and fuller, with no trace of nasal feel, although this first half is more exalted. On the Rambo, male voices tend to sound more nasal and thinner. The same is true of the female voices, which are perceived as displaced and coloured in the ISNs. The perception of both voices on the B80s is much more in line with reality, despite the slightly ‘pushed’ impression given by the headphones. The mids are denser, fuller, fuller and more balanced on the B80s. Although female vocals may sound a little sharper and more appropriate on the ISNs.
The only place where the Rambo seems to outdo the B80s is in the highs; their initial sparkle is brighter, a little thinner, not as smooth and nuanced as on the B80s. That sparkle lends more energy and naturalness to the high end.
Isolating detail, neither wins the battle with clarity, as both are dark and struggle to be resolute and defined in the deep layers. It is difficult to distinguish micro-detail in both. Perhaps there is a point of brightness in the ISNs that helps them to be more defined in some areas, while the greater sense of separation and more open scene of the B80s helps at other times. It is difficult to distinguish layers in both models or to discern a clear, sharp background. On the other hand, it is easy to get a fuzzy feeling on both models, although again, the higher spark point improves the perception of nuance on the Rambo.
Conclusion
The NiceHCK B80s successfully revisit the PK capsule. With a spectacular low end, full, deep, punchy, energetic, full, dense and dark, worthy of a good IEM, the B80s achieve a very well grounded, open, wide sound with excellent lateral envelopment. It is a warm profile, in which the notes are perceived well separated and with sufficient clarity, while the treble is smooth and nuanced. On the other hand, NiceHCK has adapted to market trends and offers a thick cable and a balanced 4.4 mm plug to achieve the best result thanks to the extra power provided by this connection. Last but not least, the price and the level of own-brand accessories also make it a key model in its price range.

NiceHCK offered me this model, in exchange for writing an honest review. I want to make it clear that all my opinions written in this review have not been conditioned by this fact, nor will I ever write anything that I do not really think or feel here. I will only write about my personal opinion in relation to the revised product.
