Who is SHOZY?
Founded by an experienced engineering and designing team, SHOZY performs amalgamation with aesthetics and sound design. SHOZY is based in Shenzhen, Guangdong and registered in China and Hong Kong. They make desktop amplifiers, DAPs and IEM/Earbuds. This is my first rodeo with a SHOZY product, yet there was instant involvement with the B2's fit and sound.


Here is a partial list of what they make:
They make the Magma IEM, the Ceres IEM, the ELSA IEM, the Black Hole Mini, the Black Hole IEMs and the Rouge IEM. They also make the Form 1.4 and Form 1.1 IEMs, plus the V33 and V33 Pro IEMs. They make the CP 3ba iem, and the CP 5ba iem. They collaborated to introduce the POLA39 IEM and make the Alien Gold Edition DAP.


The SHOZY SCB2 IEM is a collaboration with the ISN cable company. Joining the B2 with the ISN SC4 cable resulted in the SBC2 IEM. Truly a meeting of both cable technology and IEM technology.

The SHOZY SCB2 can be purchased for $299.00 here.

Every once in a while form factor will be designated by use, and here it is.

Either you like the look of the B2 or you don’t due to aesthetics being a personal value. Here is a unique combination of form and usability. There are vents at both faceplate ends which act to allow air in and out. Such design features are actually hidden into the genius of build here. The single rear air-vent is so very close to the nozzle so it benefits from being under the ear-tip space, escaping occlusion. Often air-vents are situated far from the nozzle base. There will even be recesses for air-vents (in other IEMs) so they are not touching your skin. Such designs can be forgiven because they are doing the best they can. Meaning if one or two of those vents are occluded, we are subjected to a different sound than the engineers wanted. The precarious different size and shape of ears make the whole situation a crap-shoot. Here there is no issues with either of the three air-vents being occluded......ever.

Art Deco, sometimes referred to as Deco, is a style of visual arts, architecture and design that first appeared in France just before World War One.

Comfortability is one of the main concerns nowadays. If you have ever had an IEM that didn’t fit, you may realize this concept of comfort caries over into sound quality and wearability. Meaning you can’t actually hear the IEM correctly if it is moving around. The air-tight fit may be compromised, thus creating a different frequency response. In testing I experimented with aftermarket cables. Such experiments often included ear-hooks when provided with individual cables. Still that was only due to the sheer size of the other IEM cables in relation to the B2, that the ear-hooks were genuinely needed. The ISN SC4 doesn’t need ear-hooks as the cable is light as a feather. Also (due to tip placement) I was never worried about the B2 slipping-out. Here we are given both a good medium weight and small size. The combination is magic as far as IEM ergonomics go. Of course you can conceptualize, low weight, small size, or the opposite, big and heavy, not working out. In many way this is like the story of Goldilocks, finding balance.

Truly the size and weight work here. If you read the promotional material about the B2, you will also discover the nozzle length has been designed a perfect size. Obviously they may not fit you, do to everyone having different ears, but there are truly parameters which if followed, provide an optimal IEM shape which fits more people, than not. And that my friends is what we have. Plus smaller-medium size fits more people. A lot of this is resulting on the axis of weight. Meaning if the IEM sits inside you ear (positioned close-up) it has more weight laying inside, towards you. This balance is actually working with the tip to keep the IEM stable, and that’s what we have. Also lower weight in general gives a feeling of not wearing an IEM.

There is balance in tactile feed-back. Such a special weight is found to actually be better if the IEM is not too heavy or too low weight. Due to no rough edges or sharp corners the next positioning concept takes place. That’s right, strong corners are a silly feature that has no use in IEM design. Here the B2 has all surfaces stainless steel CNC routed to perfection. Also the very edge is 24K gold plated. Thus the combination of weight, and balance of placement go the extra mile to guaranty a pleasurable fit. Add the surface feeling plus smooth corners, and we approach world-class comfort levels.

IEMs that fit better, sound better! Strange how that works?



So let me just put this out there. OK? :k701smile:

What if we never had a choice in the IEMs we own? What if the choice was in-fact brought to us by fate? Maybe even researching and making a purchase, fate is still involved? You can’t over think this stuff, luck is always involved. We think we know our sound signature, we make a purchase, except we still don’t know if it’s the right or purchase or not. Even visiting a place to demo the IEMs, never guarantees we will be happy long term. Especially when you think there are thousands of IEMs on the market. Each one is subtly different from one another. So my question to you is…….What if you were meant to be here at this very moment in time reading this review? You were reading due to fate?

What if you were just by chance here by destiny?

Would you say that's nonsense? The reason I say all this is the Shozy SCB2 was/is kismet for me. Kismet means “fate”. When you can relate with an IEM so well that it’s beyond your logic to determine why….that's fate. I would have never chosen the Shozy B2 because I’m really not into single DDs. Also due to the fact I really believe Hybrids in the $299 price realm are better. There is this great timbre from a single DD. There is this “oneness” that can’t be found anywhere in Hybrid land. This “Carbon Nano-composite Vibration Film” is doing a little extra to fill in the blanks. Meaning the driver is separating musical elements better than most single DDs. So it’s a small difference, but it seems to be a big deal. It is layering, but also dynamic imaging and dynamic contrast. Such tool-kits, once they are thrown together...............seem add up to more, like touching a match to a puddle of gasoline!

So it’s a composite of attributes that enhance each-other. The cohesiveness is a plus, but often the sole DD can’t really do it all. The reason we buy single DDs is due to natural timbre. Also there is a blending of presentation normally where everything is connected. Hybrids (due to their nature) have bolted-on sound elements. The (Hybrid) frequency display will at times have small holes where frequencies don’t quite blend. Multiple drivers means sound tubes, filters and cross-overs……..all in an attempt to join frequency forces. Normally I simply enjoy Hybrids more due to their inherent separation and contrast. But the SHOZY B2 goes one-step further to blur-the-lines. Offering really the best of both worlds here. How?

1) Separation of sound elements close to hybrid designs
2) Special layering
3) Well spaced treble imaging
4) Well defined treble elements, even though reserved
5) Bonus levels of all the coherence single DDs are known for
6) Clear transient attacks
7) Credible note fall-off
8) Texture across the board

9) Great midrange excitement

Cable and DAP rolling:
ISN SC4 cable/Walkman WM1Z
I wanted to verify what’s up with that ISN SC4 cable. I found a song I knew really well and simply switched cables mid-song. I choose the Hansound ZENTOO 4 wire in 4.4mm. And sure enough, there was a small difference subley noticeable. Where the ISN SC4 cable is a hybrid silver/copper, the Hansound ZENTOO is OCC pure-copper. The Hansound cable added a fullness in the lower midrange that was a no-go. The transient edge of note attacks were slightly polished down with the OCC ZENTOO. Probably thinner sounding IEMs benefit from the darkness of the ZENTOO pure copper, but it was pushing the SHOZY B2 in the opposite direction.

Next I tried the Tansio Mirai Cable, such a beast of a cable added thickness, but not quite the midrange and treble clarity of the included ISN CS4 cable. Still it was a great experience for a day.

PAC480 cable/Walkman WM1A
Though after a few days of listening I determined that the Walkman WM1Z was just a hair too dark of a DAP for the B2. Sure enough the PAC480 and Walkman WM1A was maybe the ticket. The sound response of the B2 is looking for some sparkle. Such a silver/copper mixture was a nice detour, though (finally) returning to the ISN CS4 cable to stay.

Takeover
The B2 is slightly dark, yet we only discover that when we have a singular instrument which we know forward and back. Such irregularities are only met with the idea that there is actually many correct, even and complete frequency responses. If the instrument sounds natural then all is well. Just a portion of the highest (tone) character is less emphasized. The iceberg’s very tip has been sonically removed, yet we are deep in entertainment. The song starts with many elements all at once. Though to keep on course with our concepts at hand, I will bring-up picked guitar. Literally the first second before Jonas Petter Renkse sings a note, we are met with a composite of sounds. Before “She waits by the river” we hear the guitar picking........other IEMs will make the harmonics more noticeable but the tone will remain the same. Even at 9 seconds in, we are played drum hi-hat accents and cymbals. Such separation and slight forwardness is a clue as to the clockwork precision we are about to encounter. Those slight high pitched percussion embellishments are what separates the B2 from most single DDs. Most single DDs have them too rolled-off. The other DD timbre is not totally lost, but it’s not the glorious presentation we have before us. Remember this is in the first 9 seconds of the song.

We can hear that they are doing the same bass notes as the guitar, yet both are clearly heard. The vocals, while not way out front like a vocal specialist IEM, are fully heard clearly. Often in DD playback, the instrumentation is getting more emphasis. At the 4 minute 18 seconds there is a break, accentuated with a cymbal hit........then piano keys! This piano is also showing the reverb used, and sure enough, the decay is right. Slightly far off, this is the production here, where they give you quieter moments to then contrast those same moments with louder emphasis. At 4 minutes 28 seconds the intensity starts to show how the guitars and bass give a singular statement. At five minutes 21 seconds that (musical) statement is now at full speed. The drums are all encompassing with a breakdown at 5 minutes 26 seconds and 5 minutes 47 seconds...............we can hear the compression on Jonas Petter Renkse's vocals. At this point it’s the climax of the song, where they do an echo on his vocals and then the lead guitar hits. Really textbook song craftsmanship, yet they make it all their own! This “their own” has a lot to do with individual vocal tone, guitar tone.......as these are the elements the B2 showcases and what makes Katatonia who they are. They have their own exclusive sound and the B2 brings that sound to us. The musical additives are in separation and clarity. 6 minutes in the lead starts-up. At 6 minutes 25 seconds the vocal washes end the song with very noticeable strings in support.

Song summary:
The B2 did a fantastic job at conveying the true message of the song which was transferred via vocal and instrument texture. The drums, bass with guitar on-top, were always allowed to be heard as a result of technicalities and frequency response. While I have heard this song other ways, this way get accolades for natural instrument tone as well as an exciting vocal rendition.

Intro (song title)
I use this song to judge decay. The opener at 6 seconds shows dramatic big drums with decay. At 20 seconds the backing chorus takes place. Such a spectacle as the B2 is truly in its element. The expansion of soundstage! At 1 minute 16 seconds the singer Sharon den Adel makes her entrance. And what an entrance, gone from the amateur days, this band is now in top-form. They are doing music only they could do and the B2 is giving us a window into it all. The harp and bass around the 1 minute 26 second mark are musical candy. Just wow! This is what the album is about! Even this beginning is spell-binding and exotically real. That bass tone, the harp off the the left, incredible! 5 star fun, but wait.........the album hasn’t even started! This was simply the intro. At 1 minute 41 seconds you can experience her take a breath! I mean everyone has to breath, but the sound of that detail, along with the back-up chorus out to the sides, with added reverb! The big finisher or should say starter, as this is the album’s start.....at 1 minute 54 seconds.

See Who I Am
33 seconds in we hear her breath again. Then she sings! The bass is such a warm yet detailed treat. It’s not forward or back, but right in place, and balanced for an L signature. Though you would not be able to truly judge the B2, yes it’s dark, the treble is rolled-off....but there is an involvement.....it’s just so darn musical. The guitar in this song should be noted and talked about. While slightly diminished tone wise, I have often heard it brighter and more forward..........still there is something to be said for this rendition. If anything we can listen all night, as the tonal response is very listenable.

Jillian (I’d Give My Heart)
This was the big hit off the album. This album is also has been released as a video recorded concert. After seeing the concert video somehow it changed the perception of the music, as I always feel like this is a live recording, when it’s not. I can just see here singing this live when ever I hear this song. Just the fact that there is a giant chorus in the song that sounds like fans singing along with Sharon den Adel doesn’t help any. Really one of the great vocalists and the B2 doesn’t leave us wanting any more! Also the guitars here are very present yet toned down the way a darker IEM would do. The violins are ever so clear and pushing the song in subtle ways. 2 minutes 3 to 2 minutes 5 seconds the B2 does the drum accents off to the right and left very well. At 3 minutes 38 seconds we hear the harp and up till 3 minutes 54 seconds we then are rewarded with the climax to the song.

Album summary:
While I have heard this song performed many different ways, the B2 does it justice. While arguably not perfect, it’s a nice detour in presentation. The stand out feature resides in big pompous bass disclosures, while not the cleanest, they convey the meaning of the song. Sharon den Adel with her voice, make this what it is. And the B2 does her justice too. While maybe not the definitive rendition, it’s the best I’ve ever heard $299.00 play it.

Taylor Swift
reputation

44.1 kHz - 16 bit

This album showed me I was at full burn-in plus the special qualities of the ISN CS4 cable. As when everything finally comes together, it’s quite startling. Literally everything song on this album is a masterpiece of modern engineering. While with the wrong headphones it may a case of the (musical) story not working out? Here we are in the B2’s backyard, right at home doing such modern day sonic fireworks.

Look What You Made Me Do
Nothing like reanimating a pop legend. Such antics walk that line of being a faded glory or in-fact sonically permanent. Permanently good? A Pop song? I don’t know, but what I can do is fully get into what’s going on here with the B2. Interesting too, playback now is killer with the TA desktop as well as the Walkman WM1A, why? Probably burn-in is complete as well as the magic of the ISN CS4 cable? Probably everything? But the slight shimmering bells of the intro way high up on the right channel at 14 seconds, let us know we are experiencing full-frequency response. The magic here is the imaging and layering. That and the pure speed of the transient response, as the effects are exploiting the response of modern sound recording. This number is sprinkled with a truck-full of sonic effects and we are siting front and center. I mean if you know this song, then you know what I’m taking about. To highlight, the bass which is red-lined to compression. All a set-up distraction for the better bass to steal the show as a drop-in at 31-32 seconds. The continuation of the bass drop phase then continues at 34 seconds to show the B2 knows exactly what this tone is about. Basically the song hasn’t even started but we are thrilled with the technicalities. The way Taylor Swift’s voice is replayed is perfect. It’s really an entire room of Taylor Swift clones singing. Countless tracks of overdubs, self-chorus and panning effects are at the point of overwhelming us. If one Taylor is good, 50 must be better? The producers go from singular vocals to elaborate overdubs..........we can notice them with the B2. Her echos at 1 minute 41 seconds seals-the-deal; we are fully amazed. The B2 strutting it’s world-class soundstage, in-fact an abnormality for single DDs? Now, you know why it’s my favorite DD in history. After putting up with the slight draw-backs single DDs have, you make excuses for them. But no excuse need here..........none!

Sound Generalizations:
Studies of the frequency response graph would have you believe a bass storm is brewed. There is no denying that’s true. But looking closer we can see the the outer most reaches of the sub-bass have a distinct rolled-off. Such becomes a reality of single DD make-up..............common in my experience anyway? This is still definitely an L shaped response. Yet due to the technical-performance the music shines through. Add the right cable and the important part of the frequency response is parlayed. Get the resolution of a desk-top, combined with that (SC4) cable and again things go to another level. The scalability is real, and will show you how a desk-top wins out over a DAP. At the same time (due to FR forgiveness) the B2 still comes off easy going from a phone. Of course this exact tune is not for all. The old-school (detail at the sake of brightness) style of listener/reader should have stopped reading when he viewed the graph. :)


Treble:
Such items found inside the treble region are subdued, yet still there. It’s this softness, this politeness that somehow allows such aspects to be heard. Through spacial placement, cymbals and hi-hats are noted……yet they are of a reduced physicality and shine. The first pinna peak is at 2.5K, then a dip and a rise, with the most energy at 5K. Such a set-up bestows a character reflecting-off the lower midrange and below bass storm. It is this complete balance as always, that provides our general character. But within that replay, treble imaging is our friend.................though tit for tat shows the midrange to really be the ultimate provider of the dynamics here.

B2-Shozy.jpg


Midrange:
The midrange languishes in heavy lower mids, yet a-top of that is seen a highly resourceful and competent midrange. Such a place is where the action is. This separation and imaging is where we get our value. This style of layering shows a window into the movement going on. Now normally you would think the expanded midrange of the Walkman WM1A would be the key to this magic, when in fact it’s somehow the desktop? What is happening is the TA-ZH1ES desk-top is providing better resolution across the board, and the B2 reacts. This resolution gets parlayed into imaging farther out into the soundstage, and more separation results in better contrasts, thus clarity.


Guitar and vocal replay:
This style of response does not high-light vocals like a vocal specialist IEM would. Such character still goes to perform vocals in an adequate manner. While maybe slightly pushed back and lackluster, they don’t rune the moment. There is a separation of instruments yet guitars are darker (yet accurate in timbre) and showing less-bright aspects of replay. It’s this realm of character where there is a range of acceptable tone. Also guitars are fun, but probably not the B2’s strongest point. Both guitars and vocals can be noted as slightly toned down, yet the benefit here is longevity of listenability. Also with such a pinna gain level at 2.5K we are fully gifted with zero chance of pinna gain heat, ever. What replaces such minor deficits takes place due to the broad top to bottom soundstage as well as a good front to back arraignment. The layers existing go to perform a style of separation, so needed and critical to make this whole signature work-out in the end.

Bass:
Laughably many would take offense to the low-end presentation here; at least graphed here. And it goes without saying the success of the B2 has resulted from joining it with the ISN SC4 cable. Such appliances go to lift the treble and midrange just high enough to find correction. The bass is really a focus of both the upper bass and lower midrange. Such an area is of supreme prominence and intrigue. This is in-fact where we gain our over-all character. Gone is that super low-end rumble. As always (with single DDs) a little is taken off the top and bottom. I can’t help but think folks would enjoy this style of bass, as there is nothing really obnoxious about it. It is this difference that really makes it not a basshead IEM, as truthfully it’s a lower midrange IEM.

Conclusion:
The B2 delivers where it counts, a big sound for such a little IEM. Such completeness in correctness means the B2 is capable of doing very little wrong. While far from perfect, the B2 offers exceptional technicalities, far above its pay grade. If it’s for you, I can’t say, but I can say it’s for me! Such fit and comfort are without parallel. Such attention to detail make the B2 a keeper. While $299.00 is a lot of money, the SHOZY B2 is a value. Rewarding its owner by making the most out of the 10mm Dynamic Driver design. Such values are special and useful if you have one IEM or a collection. With its patented ART DECO design and unique nozzle, the B2 solves problems encountered by lesser designs. You can choose copper, silver or titanium nozzle filters. You can try out different cable unions, though if you’re like me, you may find the included ISN SC4 cable best. The SHOZY SCB2 is the complete package. Rarely does design, value and sound quality exist in a single package, but it does here; don’t miss out of the fun!


The SHOZY SCB2 can be purchased for $299.00 here.

Excellent review as always.

Great review that really hits the mark! Hint: when changing nozzles, it is MUCH easier to accomplish with the tips on the nozzle as the nozzles are very small and difficult to align with the threads of the body without tips in place.

Thank-you. Yes, keep the tips on to change nozzles, I found that out. Use tips to grip the nozzle. I’m glad you agree with the concepts, as you have much more experience with the B2 than I. Cheers!

Intro

The Shozy SCB2, is a product of the Shozy brand in collaboration with ISN.

Disclosure and Note


A review unit of the Shozy SCB2 was sent to me by Penon Audio, on the understanding that I would be free to give my honest opinion on these In Ear Monitors.

All opinions are my own with no influence as I avoid reading other reviews of the same item before I have written my review. I make an effort to ensure that I give the reader factual information. I have never been paid for any review, nor would I accept payment. I review as an audio enthusiast, in my own time, for pleasure. Conversely, it simply not my style to degenerate products because that is the trend or the current view of the product, I draw my own conclusions.

I have neither sold nor have any intention of selling any review unit sent to me by any company. I spent a lot of time getting to know the product before my review and in some instances I do not and may not review items sent to me because it simply does not inspire me to spend the time with the earphones or to write a review. On the issue of the honesty and reliability of a reviewer, I say to the reader of this review, you ought to read multiple reviews on any product you want to buy and read the opinions of those who have bought the item. Ask yourself if the reviews you read have given you, a similar opinion compared to what buyers said about the product and compare that to the reviews.

For my part, I put into writing an honest view of what I hear and how I hear it, based on the equipment I have in my possession at the relevant time. Sometimes with honest enthusiasm but that is a question of style. Does, that mean the product would work with your gear? What about your music? Does your music play well on these? I try as much as possible to tell you how the earphones sound with the music I refer to here but I may not have the same source equipment, DAC/Amp, as you do.

My setup for this review

I paired them with Samsung galaxy note 10 Plus and Fiio M11, as my source, and for amplification variably, The HAA FEE HA11, Fiio BTR5, the Littlebear B4X tube DAC/Amp, Rod Ran Audio DAC/Amp and Xduoo MT604 tube balanced Amp, using mostly 2.5mm and 4.4mm. I also used Amazon Music, YouTube Music, but primarily UAPP music player.

Form, Fit and Function

The package the Shozy SCB2 comes in is nicely packed in a sturdy small size cardboard box, with a magnetic clasp. The cute ear pieces are displayed at the top and then you have two further boxes underneath, one containing accessories and the other a good quality fabric case.

The fabric covered case is hexagonal and although small enough to fit almost any pocket, there is more than ample space for the earphones and cable. Inside the accessories pack are two sets of eartips, and an additional two pairs of tuning nozzles, additional because the third pair is affixed to the earpiece.

The nozzles are a stainless steel pair, a copper pair and a titanium pair. In my view the nozzles do not alter the sound drastically but they do make a marginal difference. My nozzle preference is in this order, copper, stainless steel and titanium.

The physical form of the Shozy SCB2 is, on the outer part a smooth kidney shape with a gentle crease on the faceplate. What I find interesting about the crease is that you can see through from one end to the other, it appear to act as a vent. I tested it and could hear sound coming out of it, novel way to vent the earphones, while blending the functional feature into the design, cool, if you ask me.

The frame is stainless steel in the main, with a complimentary sliver of 24 carat gold plated piece nicely set out around the faceplate. On the inside the earpieces have no contours but for me, a good fit and given the size of these cute little IEMs should fit most ears quite comfortably and snug, although a few more contours would have made for a better seal and possibly made the earpieces more secure in the ears.

I have yet to test isolation outdoors, so I cannot comment on outdoor use but I do not imagine they would fare too badly given the big sound, which we will get to in a bit.

My one reservation is do not use these when lying down (sleeping) the cable slips out when you are lying down. I am not sure if a small adjustment would resolve this issue, but they are so small and fit so easily that the temptation is use them in bed.

The Shozy SBC2 is a single Carbon Nano Tube (CNT) single dynamic driver earphone.

The cable is a beautiful piece of work! It is soft and supple it is light and so maleable that you mostly forget it is there until you look at it or touch it and then you begin to admire the work that is the ISN SC4. The cable in the box is 1.2m long. It is a weave of 4 strand pure silver and single crystal copper with 2-pin at the earphones and ending at a gold plated copper plug, what I received is a 2.5mm cable. and it certainly looks the part.

Synergy
In my view, the Shozy SCB2 are not fussy about source equipment nor do they penalise you for bad recordings. They make the most of what you put in and reproduce good sound from the source material.

Despite the above, I must say, I am taken by the synergy between the SCB2 and the Xduoo MT604, and to a lesser extent the Littlebear B4X. The upshot is that to my ears tubes and the SCB2 work very well together and would be my choice.

The sound
In short if you do not want to read the whole review: To my ears, the Shozy SCB2 are a highly accomplished set of little earphones with big sound.

They are L-shaped to my ears and pack a punch at the lower end, but do not lack detail. To my ears they stand head and shoulders above many earphones for instrument separation. You do not have to actively seek the sound of instruments to hear them clearly.

Instruments are beautifully rendered as separates but as a whole, coherent ensemble, as you would expect from a dynamic driver, the timbral accuracy is very good.

Sound signature, presentation and technicalities
As previously stated, the sound can be described as an L-shape with prominent bass, even mids and just the right side of sparkly airy treble without excess.
20220215_090502_01.jpg


Stage - Imaging is clearly perceptible, which I suspect is a direct result of the accomplished manner the Shozy SCB2 separates instruments. The effect of that instrument separation is an image in the mind’s eye of the position of instruments within the stage. However, stage? Yes, you perceive soundstage but depth and width of stage is not particularly expansive. The exception is when I used either of the tube amps, the stage is then more expensive.

Instrument separation and imaging - Just as the instrument separation is good, the dynamic range is also accomplished, in that you get instruments calmly and gently giving their sonic contribution to he music at low volume in the background while other instruments take the foreground, but crucially these earphones are technically proficient so as not to smear over the quieter background instruments, while solos or prominent passages are being delivered.

That goes for busy passages, you get to hear clearly, the sonic contribution of the various instruments in the background as well as those in the foreground. The down side of having such good instrument separation and imaging is that you capture unintended sounds, hearing the piano pedals on Dave Brubeck Quartet’s “The Very Best” album was the unintended consequence.

Timbral accuracy is incredibly good thus the effect is a realistic and seemingly accurate representation of the sound of instruments. To my ears capturing a realistic sound of a piano is difficult for many earphones, but the Shozy SCB2 do capture realistically, piano, guitar, cymbals crashes, the list goes on.

Sound check
You may want to put on your monitors of choice and check out the music using the links.

Bass
The sub-bass is present and depending on the track heavy and hard-hitting. These little earpieces are deceptively huge in sound, nothing is held back in the bass department, but more importantly it is good quality, well defined bass.

They are not tuned for ever-present bass, they are tuned to be deep bass capable, but not bass dominant, which means you get the bass your track demands but not exaggerated or constant bass.

It is hilarious when you find these little earpieces feel like they are vibrating in your ears with deep visceral bass. The mid-bass is heard and the sub-bass is felt not just as a relic of the bass guitar notes or kick drum impact, but rather at the moment of strike, huge and impactful. The mid-bass is very well defined, good quality and delivers in both quality and quantity. I love the bass from these earphones.

Brian Culbertson - One More Kiss:


The bass on this track is full and heavy and the Shozy SCB2 does it justice, it sounds and feels solid in delivery but never excessive. The steady rhythm of bass guitar is delivered with clear distinction in each note and intermittently you get the kick drum hit.

This bass on demand approach means your earphones reflect your choice of music, given it is presents the bass you put in not layered with bass regardless of track. When you consider that these earphones are brilliant at instrument separation and have wonderful dynamic range, what you get is a highly competent set. Whether you are a fan of the occasional hard hitting bass of the SCB2 or not, there is no denying the quality of the bass, the moment it strikes to the natural decay of the notes. I cannot help but enjoy the keyboards as well as the various percussive instruments sprinkled throughout the track.

Mids
Even to those who like their vocals prominent will not feel left out with these earphones. Although, I describe the Shozy SCB2 as L-shaped, to my ears, the capability of the bass (capable of heavy bass, as required) rather than dominance (constantly pumping out) of the bass, is what makes them L-shaped. The effect of that tuning is that you are not permanently and persistently living in “Bassland”! Most importantly, the bass does not bleed into the mids.

To my ears mids are evenly presented so as not to overshadow so they do not bellow at you or sound held-back. As I hear it, both male and female vocals are lush and are not overshadowed by instruments, as the mids are just right. A good solo on the saxophone, or trumpet is delivered clearly and beautifully.

The mids are not recessed, nor are they far forward and more importantly, your mids do not come with relics of bass either. The mids are to my ears sufficient and reasonably generous in their elevation without overwhelming the listener. I find the instruments and voices have strong presence here. Female voices are rendered well and male voices no less so.

Sinne Eeg - Windmills of your mind:


Her voice together with the piano kick us off with such serene clarity, the double bass then gently enters the fray and the instruments sit back making her voice come to the fore. Piano solos to tickle both your ears and your spirit. This jazz track illustrates the Shozy’s wonderful delivery of vocals.

Armik - Midnight Bolero:


This is in the classic romantic Spanish guitar style. You have several guitars weaving together to make this brilliant and gently vibrant music. This track beautifully displays the broad range of the attributes of the SCB2, especially the instrument separation.

Treble
Treble is ample, with sufficient information and detail but again, no excesses. Complex guitar solos, piano phrases are clear and detailed, this goes for high hats and cymbals. Cymbals sound natural to me, as you would expect from dynamic drivers.

Brian Culbertson - The Journey:


Apart from a good rendition of treble, this track also beautifully illustrates sub-bass delivery on the SSCB2. The track starts with the hard hitting mid-bass with strong sub-bass relics, the Shozy SCB2 then delivers delicate piano notes and shimmering chimes it is as though your auditory senses are being tested at their extremes, yet the realism of the dynamic driver on the SCB2 deliver the harmonics to gently carry you with them.

Conclusion
The Shozy SCB2 are a highly accomplished set of earphones which, quite apart from their competence in their price range, have exceptionally good instrument separation and dynamic range. Great fun!

Enjoy your music!

The SCB2 was kindly provided for review by Penon Audio. This review reflects my honest opinion and Penon have had no sight or say with regard to the content of this review. The Shozy SCB2 can be purchased here.

Preamble

The Shozy SCB2 is a collaborative project between ISN, known for their cables and Shozy the creators behind the original ‘Shozy B2’. This was an IEM I had not experienced first-hand, indeed this was my first encounter with a Shozy IEM. ISN however, are know well for their top quality cables, and in this collaboration ISN bring their expertise in the form of a silver & copper hybrid cable, the ISN SC4, to lift more detail and life from the B2. The result? The SCB2!

The SCB2 arrived into my life during a love affair with the Oriolus Isabellae, an IEM that I have since sold. They are two single DD sets with (almost) polar opposite tuning ideals. I was immediately taken aback by the dark, thick, organic and impactful signature of the SCB2 that played out in stark contrast to the dry, light-footed and brighter tuning of Isa. This impression remains to this day and after several hundred hours of burn in. I feel in a position now to comment on the quality of this IEM, who it might appeal to and what it utility it offers in terms of library replay.

Accessories & Packaging

The packaging and accessories here are what I would consider above average and very smart. A pleasant unboxing experience reveals a useful hardcase to protect the IEM, several sets of silicone eartips of varying size and a total of three pairs of tuning filters (one in situ on the IEM). I have seen a lot worse from Chi-Fi so this was a welcome surprise.

The cable, the ISN SC4, is supple 4-core cable with no memory and has a beautifully clear sheath that reveals an attractive silver/copper twist. The accessories are heavy duty and likely to last a lifetime. The chin cinch works great. As for the sonics of this cable, as a ‘cable-believer’ I have paired this cable with success across several IEMs. The silver certainly slants things towards the high frequencies adding great definition. It just so happens that these are two things the SCB2 tuning greatly benefits from (it’s almost as if they planned this?!). In fact, I have yet to find a better cable to complement this IEM, so you can buy with confidence knowing that there’s no need to switch.

Design, Build, Fit and Comfort

I love an all-metal IEM build. The SCB2 has a satisfying weight to it in the hand and the shell is small enough that it will occupy the concha shelf of most ears safely with very little chance of falling out. The small shell is contoured well with no pressure points in my ears and is light enough that it won’t cause fatigue over long listening periods. There is a vent on the inner surface of the shell and a second larger vent on the outer side that is flute-like and possibly contributes to the very unique acoustic properties of the low-end of the SCB2 (more on that later). The neck of the IEM is reasonably short and acutely angled but should not present a problem for most ears however I would advise readying a selection of ear tips of varying length/height to ensure you have enough reach on insertion to achieve a good seal with the auditory meatus. There is a luxurious gold-plated rim contouring the outer surface of the shell that really goes a long way to improve the aesthetic. It reminds me of something James Bond might wear…

All in all, I struggle to find fault with the build and fit of this IEM. Out of all the IEMs I have tried, this is the comfiest.

Sound

On the topic of interchangeable filters, there are three choices:
  • Copper
  • Stainless steel
  • Titanium
The metal and the varying filter material used in each imparts a change in sound signature with titanium being the brightest. To be frank, there is very little reason to experiment. The titanium is the way to go. Both the stainless steel and, to a greater extent, the copper dull the sound too much and things are much less enjoyable. Don’t fret, even with the titanium nozzle the SCB2 remains a warm listen. This review is based on experiences with the titanium filter.

Tonality

This is warm and dark with a downward slant as you reach up the frequency range. Either end has a degree of roll-off that when combined with its midbass emphasis produces a full bodied and intimate sound that is incredibly organic.

Bass: midbass emphasis, softer impact, texture and detail intact, natural to slightly extended decay.

The primary characteristic of this IEM is its bass – it infuses character and life. Its quantity is what I would consider ‘basshead’ but its quality is competitively ‘audiophile’ - proving that these two things aren’t mutually exclusive. The texture and detail to bass instruments is there and to my ear at least, instruments remain realistic and not overtly bloated. Impact is not the hardest hitting I have heard and the decay is somewhat extended. I find this bass suits instrumental solo works well but might lack the snappy character required for electronic or busier tracks, but this is a matter of taste. Another factor to consider here is the slight subbass roll off that I can appreciate. You still get rumble but it’s not the overarching character and people coming from an IEM with a large bass shelf may miss this. There is enough there for me to enjoy both electronic and instrumental music so as always, ‘your mileage may vary’.

Listening to Nenad Vasilic on his album ‘Bass Room’, a stand-out double bass recording, has never been better. Detail is there, timbre is accurate, tonality is organic and the pronounced midbass brings life to this recording. I highly recommend listening to this for those who enjoy acoustic performances and as a test track to gauge texture and detail within the bass realm.

Midrange: warm, good resolution, lower-mid centric, excellent male vocal replay

The heart of the SCB2 lies in the lower mid-range, it serves this up as a decadently rich sonic meal. Male vocals, bass/cello/low-woodwinds/percussion (especially bass drums) are all brought to life. The low-mid emphasis does however reduce the overall dynamics of this tuning with macrodynamic swings from the bass-mids less pronounced, as is the contours of the sound but what you get back is worth it. Male vocalists are soulful with great presence. Due to the lower mid slant female vocals come off as more distant and more dream-like and conveyed from the chest. Certainly not unpleasant, in fact, I would say this is the selling point, the beating heart of the experience and I for one am grateful Shozy went this route instead of the typical Chi-Fi uppermid/treble emphasis. Instead of artificial detail we’re treated to a warm, analogue and organic vocal presentation. Things never reach shouty levels or demonstrate any sibilance. Pianos have a lovely note weight and soft ‘voice’ on the SCB2.

I want to emphasise here that despite the overall tuning being dark and warm in equal measure you won’t miss midrange detail, it’s there and there’s enough upper mid/lower treble for a beautiful crescendo of female vocals to emerge above the lower mids. I’ve not seen a midrange like this before and I’m not sure I will see it again as the market steadily tends toward homogeneity.

Listen to Roomful of Teeth on their album ‘Wally Gunn: The Ascendant’ to see the allure of the SCB2 midrange. This is a male and female vocal ensemble recording with great atmosphere and recording quality.

Treble: good detail, softer definition, minimal air, no sibilance

The treble is in the backseat with the SCB2. There is string instrument detail and definition to keep things lively but the treble is kept in check to impart a natural and intimate listen. While air is minimal, instrument separation and imaging is still above average thanks to the technical ability of the driver. For those with high frequency sensitivity and/or tinnitus the SCB2 would be high on my list of recommendations. Some string instruments can catch you off-guard with shrill notes but this never happens on the SCB2 and it manages it without taking away too much from the natural tone of the note.

Listen to Ballake Sissoko on his album ‘Djourou’ to see how SCB2 handles strings, specifically the metallic twangs of the kora. The detailing is there but note edges are softened just enough to avoid any aggressive property to the sound.

Technicalities:

Soundstage – tall and deep with a width that extends beyond the ears, doesn’t leave me wanting any more, music is atmospheric and bass reverberates in space.

Imaging, Instrument Separation & Layering – instrument separation and imaging is good for the price but it won’t necessarily ‘wow’ due to the tuning choice and driver character that makes the image less pin-point but thankfully this doesn’t cloud the image entirely and things remain coherent. Layering is average so I would argue these are monitors best fit for small ensemble performances as opposed to orchestral or modern electronic.

Timbre – this is a coloured sound and the low-mid emphasis and the softer uppermid/lower treble does influence my interpretation here but I feel that beneath it instrument timbre remains accurate.

Conclusion

The SCB2 is a coherent single DD with a unique tuning. The tonality lends itself to long listening and its technically capable at its price point. ‘Dark’ and ‘warm’ are words we frequently see used with negative connotation in the audiophile world but it would be a great disservice to overlook this IEM just because of these characteristics. It would suit those who enjoy warmer tunings, preferably instrumental, small ensemble music (or those with treble sensitivity) and seekers of musicality over reference tunings.

Forgive me for venturing into what might come across as cringe-worthy romanticism but my feelings when listening to music have strong associations with my memories and sometimes those memories are a better reflection of what I'm trying to convey…I’ve had moments listening to world music on the SCB2 that reminds of past vacations, sitting on warm coastal sands as the sun drops beyond the horizon, with a loved one nearby and waves lapping at the shore. Moments that remind you that the beauty in life is best when shared....

The SCB2 has a big heart to share with you. It is far from a classical ‘transducer’ in the neutral sense of the word. This one has a distinct and loveable character and it’s found a permanent place in my collection for that reason.

Miscellaneous Comments

Source matching - the SCB2 is not especially picky and runs well with the M8 and my RU6 dongle. The M8 is a DAP that falls on the warmer side. Naturally given the sound signature a brighter source may compliment this IEM better but its not a neccessity.
Tips - wide bore is probably the way to go but I've also had good results with Final E black silicone tips that have a narrower bore.

This has an interesting bass character, with a heavy low end emphasis but without being a rumbling experience. It romanticises all the tunes you put through and matches really well with relaxing jazz and acoustic.

Let me know how you get on if you ever take the dive on it!

It would be interesting to read a review where Penon does not provide the IEM for free to the reviewer.

EDIT: It's not wrong for them to do, or their fault that purchasers aren't writing reviews too, and it ensures that we have some reviews at least -- but I wish there was a greater variety of sources/opinions on products they sell.

I have an SCB2 enroute which I purchased with my own dollars. I look forward to comparing them with my my Black Hole which I much enjoy. I expect them to be quite different but complementary!

I will add my personal comments but will not duplicate previous full reviews. I have owned many Shozy products and think highly of their willingness to think outside the proverbial box!

EDIT: I received my SCB2 earlier today and have briefly auditioned several of my favorite test tracks including male vocals, female vocals and a number of challenging instruments including piano, French horn, guitar, and large instrumentals as classical music is my favored genre.

My initial impressions closely parallel those of previous reviewers. During unboxing, I was surprised at the really tiny size of these IEMs! They are considerably smaller than they appear in photos. At first listen, I was greatly impressed with the weight of the sound! They have a very large and immersive presentation giving the impression of a live presentation.

Despite the ability to deliver deep and accurate bass, I never heard any intrusion to the mids and was able pick out delicate supporting instruments from the mix. To my ears, the star of the show is the sense of depth of stage they present. Instrument tonality and timbre sound very lifelike, contributing even more to the impression of listening to live performances.

I also give high marks to the beautiful included cable as it is among the best I have experienced in comparison to those included with IEMs costing hundreds of $$$ more.

At this point, I can foresee the SCB2 quickly taking their place as my overall favorite IEM for simply chilling and enjoying my music!
