ROSESELSA X AAV CJ20: Technical Precision With Cathartic & Thanatosonic Intensity

It's been a while since I reviewed a product from ROSESELSA and what I have here is their first ever mini-orthodynamic IEM model as this one was tuned for metal and rock music in collaboration with Andy AV, an audio reviewer in YouTube and also a fellow metalhead audio reviewer.

And yours truly happens to be an ardent metalhead and also loves rock music and both of my phone and DAPs have a large collection of lossless audio files and at least 70% of its overall tracks are all metal and rock genres. And also, Andy happens to be an old school metalhead and we share the same passion for these extreme music genres. I listened to all types of metal genres from Iommi-worshipping doom metal bands like Pentagram and St. Vitus up to the melodic and atmospheric sounding Folk Black Metal like Windir and Suldusk (thanks [USER=346233]@Leonarfd[/USER] for suggesting  this band to me some few years ago), but my favourite ones are definitely Thrash, Death and Black.

And what I have here is ROSESELSA X AndyAudioVault CJ20, an IEM equipped with 14.2mm of planar magnetic driver which is quite an average size for today’s standard. This planar magnetic driver has a usual construction for a compact orthodynamic structure, a thin wafer diaphragm with an embedded flat conductive traces supported by a gasket frame, and it was suspended between two high-grade neodymium magnet arrays, and with the sources relays an audio signal through the conductive traces, the magnet arrays will respond as it will also interact to have a consistent and uniform motion on its diaphragm to create sound output through air pressure. This type of a sophisticated transducer is capable of delivering a fast transient response, precise, detailed and accurate sound reproduction from deeper bass up to well-extended treble, with clarity and crisper sound on vocals and instruments.

This complex driver was then encased on a compact size inverted tear drop-shaped CNC-milled aluminium alloy shell chassis. It appears that the shells were anodised and then sand-blasted to achieve its burnish and matte-like finish on its surface. The general design on this one is somewhat of a semi-open back as it has a large cavity covered with a metal mesh with on its faceplate that it gives a utilitarian yet sophisticated appeal on its overall aesthetic. This IEM also features a proven and stable interlocking mechanism which is a bi-pin connector of a 0.78mm size for ease of detaching and unfastening with its detachable cable.

As for its stock cable, it has a four-core structure made of monocrystalline copper conductors with a sheathed fabric insulator on each strand and it also features a modular termination system that allows it to swap with other types of plugs of specific pairing with a source device. The quality of the cable itself seems flexible, yet it has rough texture and is susceptible to entangle, and also, it produces some mild microphonics when it is contacted with a fabric on my clothes. The quality of the materials of the cable will ensure a smooth transmission of audio signal with a minimal signal loss for a pure and clean sound quality.

The wearability that this one could offer is pretty comfortable as it fits well into my lugholes that I didn’t encounter any listening fatigue or discomfort during my long hours of listening session. The nozzle of this one is quite short but pairing it with some stock eartips that this set provided out of the box, particularly the wide bore ones does offer me a firm insertion and proper sealing that I have an excellent passive noise isolation that blocks unwanted noises from the outside surroundings.

The product packaging of this one has a medium-size packaging box, and it is packed with accessories inside. The packaging box’s outer design has a picture of the model along with some prints of the brief features of the model and its model name on the front, while on its back, there are some printed specifications and the picture of an exploded view of the schematics of its planar magnetic driver technology.

These are the following contents inside of CJ20’s packaging box:

• Pair of ROSESELSA CJ20 IEM transducers earpieces
• Stock cable with modular termination feature
• 3.5mm single-ended plug adapter
• 4.4mm balanced plug adapter
• PU-leather pouch
• Four (4) of balanced bore silicone eartips in different standard sizes (XS,S,M,L)
• Four (4) of balanced bore silicone eartips in different standard sizes (XS,S,M,L)
• Four (4) of wide bore silicone eartips in different standard sizes (XS,S,M,L)
• Tool brush
• Cleaning cloth
• Small booklet that features user manual and warranty certificate

When it comes to power requirement and amplification, since the CJ20 is a planar magnetic driver IEM, and this type of driver needs some better power output, nominally a current one as these types of complex drivers are known to be power hungry that makes them hard to drive. If properly amplified, this set will have a good headroom that it delivers a full, dynamic and distortion-free sound.

As for its overall tuning profile, this one has a U-shaped sound signature with a coloured tonality as it has an elevated bass and boosted treble while the midrange is on a dipped and recessed presentation.

LOWS/BASS:

The bass quality of this one is definitely punchy, impactful and somehow well-controlled as it doesn't bleed too much on the low midrange despite being a mid bass-focus tuning set. While the sub bass presence has a minor impact as it only gives reverberating and rumbling depth on bass guitars and kick bass drums and to some extent, bass vocals, the mid bass is more crucial on the foundation of the punchiness and body on bass-clef instruments and low octave male vocals.

With the instruments as we would like to feel the intensity and weight on the bass guitars as I would hear that distinctive “moah” sound from Steve DiGiorgio fretless basslines, and a galloping, distorted yet harmonising sound from Cliff Burton fingerstyle techniques. While on bass kick drums, we will hear those speedy, thunderous and lingering sounds from the double-basses, from the precision and intense endurance from Gene Hoglan, a relentless and consistent double-bass drum work from Pete Sandoval, and then the blazing speed and fluidity of Dave Lombardo.

On the low-octave male vocals, I will choose Peter Steele’s distinct bass-baritone vocals as it is known for its full, gravelly and booming voice as this set is capable on delivering that deep ringing resonance but it still like a bit lacking of the dark timbre and vocal texture that I’ve heard from an IEM with planar magnetic driver.

MIDRANGE:

For sure that this one has a recessed midrange presentation but it doesn't lean and dry as it still has enough warmth and also quite energetic due to an elevated upper mids as it is vital for vocals and also, most of the instruments in both metal and rock tracks, like the guitars, snare drums, tom-toms, sometimes organs and percussive chordophone like pianos and keyboard synthesisers. But overall, the midrange quality on this one is rather balanced, transparent and clear with some natural timbre on it.

When it comes to male vocals, I'll pick a few vox that I'm familiar with in terms of vocal volume and texture, and to think that most metal and rock frontmen are usually on baritone and tenors. And if you are looking for those deep guttural growls and high resonating shrieks from death and black metal vocals, I don't think that CJ20 will deliver that deep, rough and throaty voice quality as it doesn't have sufficient warmth and fullness on the low midrange as they sound a bit too clean and pristine, but for some tenors and countertenors, this set will execute it almost flawless with tonal accuracy.

Here are some metal and rock male vocals that I will use as a references on this test:

• Atilla Csihar/Mayhem: Freezing Moon -  known for his raspy, hissing, deep croaks and groan vocal style, and while its hissing and raspiness were somehow depicted properly in this set, his groans and croaks seems lacking a bit of that depth that it should sound like.
• Mortuus/Marduk: The Blond Beast - Noted for his hoarse and harrowing yet articulate vocal style, and just like Atilla, it has insufficient depth and weight.
• Quorthon/Bathory: Sacrifice - With his distinct raspy, distorted and constricting unrefined pitch on his raw vocals, the CJ20 able to capture those raspiness and screeching but still lacking of that vocal depth.
• Jurgen Sandström/Grave: Into The Grave - his vocals here sounds deep, cavernous and powerful with those guttural growls in which this set is barely able to capture those deep and gravelly groans, though not that ideal in terms of tonal accuracy.
• John Cyriis/Agent Steel: Bleed For The Godz - his vocal rendition here in CJ20 is excellent as it was able to capture his rapid, sharp and vibrating high-pitched vocal delivery.
• Tony Moore/Riot: Thundersteel - Almost similar to John Cyriis, he also has a high pitched piercing vocal belting with more melodic approach and a bit gritty.
• King Diamond/Mercyful Fate: Witches’ Dance - One of the few metal vocalists that employs a countertenor style of singing with light, ethereal and a bit coppery seems to sound almost accurate on this IEM.

• John Fogerty/CCR: Have You Ever Seen The Rain - Known for his raspy, squawk-y and sustaining vocal style in which this set was able to capture it close to realistic to its tonal colour.
• Robert Plant/Led Zeppelin: The Rover - In this track, he sang with his distinctive tenor voice in a  clear and dazzling manner with some wailing and soaring sound from his head voice that this IEM was able to render properly.
• Freddie Mercury/Queen: Killer Queen - His fame as an multi-octave singer, in this track, his voice here sounds rather mild, soft and sultry with a multi-layering of vocal harmonies on its recording that CJ20 is able to play to perform it thoroughly.
• Klaus Meine/Scorpions: Always Somewhere - His expressive lyric tenor sounds bright, delicate and clear pitch on this track that this IEM is capable to project its vocal quality.
• Eddie Vedder/Pearl Jam: Daughter - Known for his deep, resonant and a tad husky baritone vocals in which this set marginally captures its tone and timbre albeit with less weight and vocal depth.
• Scott Weidland/Stone Temple Pilots: Still Remains - With his emotional deep expression from his mildly warm, evocative and raspy baritone voice on this track sounds pretty impressive on this one due to its tuning which is quite ideal on his vocal qualities.
• Eric Martin/Mr. Big: To Be With You - He is one of the foreign act rock vocalists that I've watched in a live performance during their concert here in Metro Manila a decade ago, and on what I've heard that his vocal quality are almost the same both in live performance and studio recording as his dramatic and soulful tenor has a warm, raspy and sweet sound with some added breathiness in which the CJ20 is able to deliver it almost accurately.

As for female vocals, in this tuning, it seems that they fare well on this set as most vocal types in rock and metal usually range from mezzo-sopranos up to sopranos in which you can find them mostly on symphonic and power metal genres. And these vocals are known for their coppery, fiery, brilliant and shimmering sound that will be depicted properly due to CJ20's upper-mids emphasis, that gives a more lively, atmospheric and euphonious sound.

Here are some metal and rock female vocals that I will use as a references on this test:

• Tarja Turunen/Nightwish: Sleeping Sun (2nd version) - She has a dramatic soprano as her voice here sounds more crystalline and silvery with still good vibrato control compared to the Oceanborn version on this track which sound more rich and eerily, and CJ20 is capable to project her vocals at fullest potential.
• Kate de Lombaerd/Acid: Max Overload - Probably the first woman that fronted a speed metal band in the 80s as her raw, raspy and fiery voice were portrayed correctly on this IEM.
• Sabine Edelsbacher/Edenbridge: Starlight Reverie - Another soprano vocalist-fronted power metal band, her vocals sound ethereal, rich and satiny with excellent range and sustaining in this set able to render her vocal prowess.
• Sharon den Adele/Within Temptation: The Cross - She has a distinctive mezzo-soprano voice which has a nasally-like yet velvety and hefty sound with a delicate tone, and yet the CJ20 captures it but with some added coppery tone.
• Liv Kristin/Leaves Eyes: Nymphetamine (she serves a supporting vocalist) - Known for her angelic-like, silky and ethereal soprano vocals which was in contrast that deep growl and high-pitched shriek vocals from Dani Filth in which former vocal that CJ20 is able to depict it properly.
• Sabina Classen/Holy Moses: Current of Death: One of few frontwomen in a Thrash metal scene and with her coarse, scratchy and raspy vocals makes her distinctive vocalist as the CJ20 able to render it naturally.

• Gun-Marie Fredriksson/Roxette: Dangerous - She has a rich, husky and a bit energetic sound that this set is able to deliver, albeit it loses some of its vocal weight.
• Christine McVie/Fleetwood Mac: Little Lies - Known for her lilting voice with its warm, smooth and a bit sweet sound in which the CJ20 portrays it almost correctly.
• Belinda Carlisle/The Go-Go's: Fading Fast - She has a vocal quality that sounds bright, clear and sweet that seems quite perfect for this IEM's tuning.
• Debbie Harry/Blondie: Maria - In this 90's track from Blondie, she has a warm, smooth and smoky vocal quality in contrast with her previous voice that sound a more softer, tender and delicate on her earlier voice works, and then once again, it perfectly fits well with the CJ20.
• Dolores O'Riordan/The Cranberries: Hollywood - It has similar vocal intensity with her voice on “Zombie”, as she also has a lilting and musky sound as she conveys her emotional appeal and expressive conviction of this track in which it fares well on this set.

In regard to instruments, depends on the recording and mixing of some tracks, it gives more crisp, sustaining and crunchiness on the guitars particularly on the lead guitars as it gives those complex solos, riffs and chords from these virtuosic axemen, while on the rhythm guitars, they sound less warm and bit lean as I noticed that its sound less chuggy but still a bit brighter and precise compared to the bass guitars as these guitarists deliver some chord foundations with percussive-like grooves and strumming patterns. When it comes to percussives, snares sound bright, crisp and incisive on this one while the tom-toms have enough warmth, crisp and resonant sound every stroke.

HIGHS/TREBLE:

The treble response on this one is definitely on the brighter side of tuning that it will give more shimmer, brilliance and airy presentation while maintaining some controlled peaks between the presence and brilliance sections that it doesn't sound too harsh and sharp. Although there is a noticeable mild planar-y timbre that produces the metallic sheen of sound on it.

That elevated sections on the upper mids up to presence section will give more clarity, definition and detail on the articulation of vocals and an incisive attack on instruments. On some tracks, there's some instances of mild tinny and a tad shrill when I tested this set to one my reference track for sibilance and stridency check, Iron Maiden's Seventh Son Of The Seventh Son.

There's an ample airy extension on its brilliance section with an intense sparkle that gives more adds more gleam on some percussive instruments. The said instruments are all treble-clef ones, cymbals and hi-hats, as the former will produce a varying sound from crash and ride cymbal strikes as they sound lustrous up to metallic brilliance, while the hi-hats have a crisp, sizzling and tight sound, these instruments are all indispensable part on skank beats, gravity blast and blast beats drumming as they adds some tonal accents on them.

SOUNDSTAGE, IMAGING & OTHER TECHNICALITIES:

Just like you will expect an IEM with a mini-orthodynamic driver that it will deliver an excellent technical performance, and indeed that the CJ20 have those characteristics that they will convey upon our listening session. While this IEM isn't the most widest sounding planar IEM that I've heard but it doesn't sound intimate nor too confined in my aural perception as it has a perceived moderately roomy soundstage size enough to define some sense of broadness on lateral width, good height ceiling reach and immersive depth distance from front to rear.

On its stereo imaging, it presents a stereoscopic presentation in a well-layered acoustic landscape with excellent separation and precise placement of musical elements in which I was able to locate them accurately while playing some of the complex multi-instrumental rock tracks and other intricately produced genres like orchestra recordings and jazz will be effortless depicted.

When it comes to its driver coherency, planar magnetic drivers are exceptional type of advanced transducer as they are known their precision, speed and crystalline clarity, and CJ20 have those characteristics as it has a fast transient response for its bass attack, and then, a clarity, accuracy and detailed for the rest of frequency response.

As for its resolution capabilities, this one can deliver that large scale of varying degree on impact and punchiness on its volume dynamics on the chorale lines and instrumental passages from its quietest section up to its loudest level, while its microdynamics have a sharp definition as it was able to capture a substantial amount of fine details and other subtleties from an audio track like notation attacks, note textures, vocal delays and instrumental reverb tails.

Here are some of the metal tracks that it seems that give me that spacious presence with some well-defined placements of instruments and vocals:

• Mayhem - Freezing Moon (Alive)
• Kreator - Horde of Chaos
• Dark Tranquility - Damage Done
• TesseracT - Juno
• Kalmah - The Groan of Wind
• Wintersun - Beyond The Dark Sun
• Necrophagist - Stabwound
• Blind Guardian - Time Stand Still
• Stormwarrior - Thunder & Steel
• A7X- Welcome To The Family

PEER COMPARISONS:

HIDIZS MP145 PRO

• HIDIZS’ latest flagship planar IEM and a reiteration of the MP145 model line-up, and like the CJ20, it has a single driver with similar driver technology.
• It has a bit larger planar magnetic driver by a slim margin compared to CJ20 but it incorporates some of its the latest breakthrough on this driver technology, with stronger magnetic flux that makes it even more easier to drive and it was encased in a rather large solid aluminium alloy shell structure.
• This one is full-packed with quality accessories inside of its packaging box, including  three types of ear tips, a PU-leather hardbound storage case and a premium-looking cable with modular termination.
• Since this is a HIDIZS product, it has interchangeable tuning filter nozzles in which it offers a variety of tuning profiles, from mild U-shaped to warm U-shaped sound.
• In comparison with the CJ20, I’ll use the Gold Tuning Nozzle on this one, this one has a rumbly, precise but a bit tighter bass response, less recessed but it has a bit more warmth and also has energetic tuning on its midrange and then a bright and sparky treble of the same intensity but it has more brilliance air extension.
• As for its overall technicalities, this set and the C20 both have impressive technical capabilities but the former has a bit wider soundstage projection.

SHOZY P20

• An old model from SHOZY and like the CJ20, it has a single driver configuration with similar driver technology.
• It uses a bit larger planar magnetic driver and it was encased in a large solid aluminium alloy with a shape similar to one of the phases of moon
• On its product packaging, it has almost similar quantifying amount of contents with the CJ20, and while it has a better storage case, its stock cable doesn’t have a modular termination feature.
• This set has a mild U-shaped sound with a warm-ish balanced tonality.
• In comparison with CJ20, this one has a punchier, more tactile and impactful bass response that it adds more darker and deeper tone on bass-clef instruments and low octave male vocals, a warmer and richer midrange presentation but its upper mids is a bit attenuated that it loses some its clarity and crispness on the strings, woodwinds and female vocals, but it adds more punchiness on some percussions and a smooth, deep and plush sound on baritones and contraltos, and then a smoother, relaxed but less airy treble response.
• On its technical aspects, this one has a similar perceivable soundstage size comparable to the CJ20 but it has better depth, a concave-like stereo presentation with a fairly-layered soundscape and a more firmer and impactful macrodynamics but less sharper micro-detail definition as they are a bit blunted.

LETSHUOER ASTRALIS

• A new and the first model line-up from LETSHUOER latest series of planar IEMs.
• It features a larger and a newer generation of planar magnetic driver and it was encased in a solid yet lightweight aluminium alloy shell chassis.
• As expected from a LETSHUOER product, it is sufficiently packed with accessories inside of its packaging box, and among them is a high quality stock cable with modular termination feature, a solid TPU storage case and a headphone dongle adapter.
• This one has a bass-boosted warmish-neutral tonality that makes a L-shaped sound profile.
• Compared to the CJ20, this one a bit punchier, a tad more bodied with a rumbly end on its bass response, a tad warmer but seems more balanced sounding midrange, as it has a deep, more plush and rich texture on its male vocals and a smoother and velvety but less gleaming sounding female vocals, and smooth and even  treble response with similar amount on its airy extension.
• As for its overall technical performance, it has almost similar technical performance with the CJ20 in most categories but it has a less sharper definition on its microdynamics.

KIWI EARS AETHER

• One of the latest models from KIWI EARS with a planar magnetic driver just like the CJ20.
• It sports a larger planar magnetic driver with a diameter size 15.5mm, and it was encased in a large composite shell chassis.
• The product packaging of this one is stuffed with accessories inside like a thick stock cable but doesn't have modular termination feature, a solid IEM storage case and three types of eartips that it offers.
• This one has a balanced-neutral sound with a tinge of brightness on its overall tonal profile.
• In comparison with CJ20 in which this set has a less colouration, this one only has a sufficient punch albeit a bit tighter yet rumbly, a more balanced midrange as it has ample warmth for and energy on its dynamic texture that gives more natural yet accurate sound on vocals and instruments and then a less brighter but still has sufficient sparkle with better airy extension.
• On technicalities, it appears that among the peer comparisons, this one has the widest and cavernous soundstage that we can perceive from an IEM, and like the CJ20, it has a well-layered soundscape with good separation and precise placement of instruments and vocals, and also a pretty resolving resolution capabilities.

To conclude this product assessment, this set is truly made for audio enthusiasts  who are in the same genres as mine as to how it was tuned as it was intended. I know Andy with some of his tonal preferences which aligns with his ideal tuning that will suit well to capture the intensity, aggressive, tenacity and grittiness of metal music and then, the energetic, driving beats and explosiveness of rock music, and this commendable product is the result between him and ROSESELSA as they believe that it will capture some sections of audio enthusiasts in the audio market in which yours truly belong to this segment.

As I mentioned about the aggressive, grittiness and intensity of the metal music, the CJ20 is able to deliver it as this one is also coloured sounding that gives a more fun, engaging and lively that we able to enjoy that raw and power that actually helps to relieve and control ourselves from negative emotions like stress and anger. And to think that in some studies, listening to these extreme music actually helps you to calm down and boosts some positive energy and some sense of empowerment.

The CJ20 has a planar magnetic driver that ensures fast, clarity and detail on its overall sound quality with excellent technical capabilities. And also, with its coloured tuning, you can also enjoy genres not just metal and rock music but also on other popular genres like standard pop, new wave, latin, dance and even jazz in which I tested some few Miles Davis, John Coltrane and even Lee Morgan tracks in my track collection. And so, I will recommend this set for audio enthusiasts who are looking for fun, engaging and lively sound IEMs that they can simply enjoy although you still need some better sources to pair with it.

● With that texture quality on low midrange with just enough warmth, it won't give that full, deep and gravelly sound from growls, groans, howls, guttural and squeals from both death and black metal vocals.

● Wishing for a more KVLT-y design on its stock cable and also it is somewhat susceptible to microphonics.

● Less warm texture on the midrange that might sound a bit lean especially if you are into a warmer tuning profile.

● its bright and energetic tuning might be too intense to some treble-sensitive folk.

● Its tuning is too diabolically coloured sounding for neutral heads.
