Yanyin Technology, a relatively new audio brand established in 2020, has gave me the opportunity to review their latest product, the successor to the original Yanyin Canon, the Yanyin Canon II. Since I have no prior experience with Yanyin products, this will be my first review of one of their In-Ear Monitors.

DISCLAIMER:​

• I have no affiliation with Yanyin and have not received any monetary compensation during or after writing this review. This is a loan unit in exchange for an honest and unbiased review.
• As a non-professional reviewer, I aim to use simple terms that can be understood by both beginners and experts in the hobby.
• Please keep in mind that the opinions expressed in this review are subjective and based on my personal experience with the unit. I encourage you to try the product yourself to form your own opinion.

PACKAGING​

​

The unboxing experience of the Canon II has "chi-fi" screaming on the box. The packaging itself lacks a premium appearance. Upon opening the box, it becomes evident that it appears to contain numerous items, but in reality, it is predominantly filled with foam padding.​

BUILD QUALITY​

Regarding the build quality, I would describe it as decent. The Canon II uses a 1DD+4BA configuration. The drivers are encased in a striking all-resin shell with an attractive and stylish design. The cables, while adequately thick and functional, are not designed to be modular, which is somewhat disappointing considering the price of the Canon II.

SOUND​

The Yanyin Canon II produces a dark yet inviting sound that completely immerses my ears in a rich, immersive audio experience.

BASS

The Yanyin Canon 2's bass possesses a substantial amount of weight and thick texture without an excessive bloat. The midbass offers a modest punch that doesn't bleed into the mids, the sub-bass dominates the bass region, delivering deep and solid rumbles.

MIDS

The midrange offers a soothing and enveloping warmth that brings out the richness and natural timbre of vocals. However, I did notice that the instruments fail to stand out as I'd prefer, particularly when seeking the distinct guitar bite in tracks like Polyphia's "Playing God" and Jimi Hendrix's "Little Wing." They tend to sound somewhat laid-back and lack the expected impact. Even in piano-heavy compositions like Piano Concerto No. 2 in C Minor, Op. 18: 1. Moderato (starting at 5:56), the piano strikes feel a bit too light. On the bright side (or on the warm side), for those who prefer this laid-back and warm characteristic over clarity, these IEMs are non-fatiguing and well-suited for extended listening sessions. The upper-mids exhibit a roll-off, which impacts the bite of specific instruments, resulting in a softer texture and a notable sacrifice in terms of clarity.

TREBLE

The treble is tuned to a safe and rolled-off extent, but this comes at the cost of sacrificing clarity and fine details. This can lead to issues with instrument definition, making cymbals, for instance, sound somewhat dull. The Canon II will find it a challenge to retrieve micro-details. If you're someone who values intricate treble nuances, this tuning may not be suitable. On the other hand, if you're treble-sensitive and prefer a milder treble, this could be an ideal choice for you.

TECHNICALITIES

When you gain something, you lose something. This applies to Canon II's philosophy (in my personal take) because of its safe, darker tuning we lose some of the finest details. However, it doesn't mean the Canon II is a total slouch. Although the soundstage lacks an expansive and holographic feel, it still manages to provide a reasonably wide and deep headstage, preventing it from feeling overly congested. I can discern the instrument placement with some clarity, but the finer details and definition remain somewhat distant, and the roll-off hampers its ability to reproduce those intricate nuances.

TUNING SWITCHES

To be fair, I did not find the tuning switches having significant changes to the overall profile of the Canon II. Well, me might hear some adjustments here and there but it is not that crucial and I believe I find the Canon II perfect as it is without the switches. But yeah, I'll have them do their way. To conclude, I won't bother discussing too much about the switches.

DEVICES USED​

• Astell&Kern SR25
• HIDIZS S9 PRO PLUS
• Fosi Audio DS1
• Audioquest Dragonfly Red

TEST TRACKS​

CONCLUSION​

Pros:

• Thick bass
• Rich, immersive mids
• Safe, smooth treble
• One of the decent dark sounding profile
• Decent build-quality

Cons:

• Rolled-off treble
• Expect technicalities to be underwhelming
• Tuning switches doesn't do much
• Underwhelming inclusion for a $379 deal

On my take, it's a rarity to come across earphones with such a dark profile that still perform admirably. While this might be a bit too extreme for some, I personally find them to be quite remarkable and a unique offering in a market saturated with earphones featuring Harman or V-shaped sound signatures. Additionally, the design is quite appealing, although the tuning switches seem somewhat redundant, as they don't change the Canon II's sound that much. Nevertheless, if you're in search of a dark sound profile that provides a rich, immersive, and captivating listening experience, these earphones are worth considering.

​

PACKAGING​

The S9 Pro Plus arrives in an eye-catching package, featuring a plastic case. Upon opening the package, we have the a USB Type-C cable, a Type-C to Type A adapter, and, of course, the dongle itself. No instruction manuals are included on the dongle.

BUILD QUALITY​

The build quality of the Hidizs S9 Pro Plus can be described as average for its price point. Although it is lightweight, there is some noticeable LED bleed on the plastic faceplate, which gives it a somewhat cheap feel. Additionally, the design of the Type-C cable is a bit impractical, as I found that the dongle only functions properly with a specific cable orientation. For it to work without interruptions, the logo should be facing up when connected to the phone. Otherwise, it won't work. Updating the firmware did not help, I believe this is a faulty hardware design that is not very user friendly.

SPECIFICATIONS​

• ES9038Q2M High Performance DAC Chip
• PCM Supports Up to 32bit/768kHz
• Native DSD Supports Up to 512
• Physical Buttons for Volume Control & 7 Filter Option
• 4.4mm Balanced & 3.5mm Single-ended Output
• 138mW+138mW@32Ω 3.5mm SE / 180mW+180mW@32Ω 4.4mm BAL
• Sampling Rate Indication RGB Lighting
• Compatible with all platforms: Windows/Mac OS/iPad OS/Android/iOS/Harmony OS
• Hi-Res Audio Certification

FEATURES​

IT HAS SEVEN FILTERS! WHO KNEW?​

The Hidizs S9 Pro Plus boasts two dedicated buttons, one for volume up and the other for volume down. In addition, there's another feature that may go unnoticed unless you actively look for it online (Thank you, lack of user manual!). If you simultaneously press both buttons, you can access the filter selection, offering a total of seven filter options.

• Anodizing fast roll-off (Default Filter): Vocals are slightly forward, and high frequencies are extended with reduced resonance.
• Linear phase fast roll-off: Enhanced analytical capabilities, delivering a clean and crisp sound.
• Linear phase slow roll-off: Enriched harmonics, full low frequencies, and natural reverb.
• Minimum phase fast roll-off: Balanced and moderate sound.
• Minimum phase slow roll-off: Clean sound with a forward position.
• Hybrid fast roll-off: Soft and smooth sound with enhanced detail.
• Brick wall: Excellent dynamics and strong presence.

The filters didn't introduce any significant changes to the sound, especially if you simply just enjoy listening to it without being overly-critical like an overly obsessed audio-nerd.

IT HAS TWO PORTS!​

The S9 Pro Plus is equipped with two headphone jacks, supporting 138mW at 32 Ohms through the 3.5mm port and 180mW at 32 Ohms via the 4.4 balanced port. When connected to the balanced port, it can effectively power the Sennheiser HD600 at approximately 70%-90% volume, being the safest. The S9 Pro Plus demonstrates its capability to drive planar earphones and even hard-to-drive headphones, all within its compact form factor.

DEDICATED COLOR CODE FOR EACH SAMPLING RATE​

While not particularly groundbreaking, it's a convenient feature that provides the on-display sampling rate information. This can be considered as an aesthetic enhancement, and it's worth noting that it's a feature found in a few other devices, such as the Audioquest Dragonfly.

• Yellow: DSD 64/128
• Purple: DSD 256/512
• Blue: PCM 176.4/192(kHz)
• Red: PCM 352.8/384(kHz)
• White: PCM 705.6/768(kHz)
• Green: PCM 44.1/48/88.2/96(kHz)

The S9 Pro Plus is lacking MQA support, but it remains a versatile dongle that is compatible with various codecs. If you need a dongle from HIDIZS that supports this codec, you should check out Hidizs XO.

SOUND​

While I have strong criticisms regarding the build quality of the Hidizs S9 Pro Plus, it compensates with exceptional sound quality. This device provides ample power to drive both my IEMs and headphones while keeping noise and hissing to a minimum, resulting in a clean, distortion-free audio experience. It truly enhances the audio characteristics of my gears, allowing their strengths to shine at their most decent potential possible. The S9 Pro Plus's sound quality can be described as clean, detailed, and free from any hissing, offering remarkable resolution and a non-fatiguing listening experience with plenty of intricate details.

HOW ABOUT HARD TO DRIVE HEADPHONES?
Fortunately, my friend loaned me his Sennheiser HD600, allowing me to evaluate it with this dongle. While it may not completely unleash the HD600's potential, as high-end desktop stacks can, the headphones can still be comfortably powered at around 70-80% volume with surprising clarity, resolution, and power. It's important to highlight that for optimal performance, you should connect it to the 4.4mm port, as it doesn't perform well with the 3.5mm port, even at maximum volume, due to a lack of driving power.

COMPARISONS​

vs Hidizs XO:
Let's start by comparing it to its sibling first. The Hidizs XO is limited to supporting DSD files up to DSD256, whereas the S9 Pro Plus can handle up to DSD512. While both models deliver a commendable level of clarity and attention to detail, the S9 Pro Plus stands out for its cleaner sound quality without any harshness compared to the XO. It's worth noting that the XO supports MQA, a feature the S9 Pro Plus lacks. In terms of build quality, the XO takes the lead, but the S9 Pro Plus offers independent volume control and capabilities such as the 4.4mm port that the XO doesn't have, making it a versatile choice. The S9 Pro Plus is the clear winner here.

vs Audioquest Dragonfly Red
We must acknowledge that even though it was released in 2012, the Dragonfly Red continues to prove its worth as a reliable dongle. It has truly stood the test of time and holds a special place in my heart. However, when it comes to specifications, the S9 Pro Plus clearly takes the lead. It offers a broader codec support compared to the Dragonfly Red, which is limited to 24-bit/96kHz. Another advantage of the S9 Pro Plus over the Dragonfly Red is its hardware controls and readily available Type-C connection, while the Dragonfly Red relies on a USB-A connection. It's important to recognize that the Dragonfly Red was not originally designed as a mobile phone dongle but rather as a laptop/desktop accessory. In terms of driving power, both dongles can handle the Sennheiser HD600, but the S9 Pro Plus requires less power and, unfortunately, delivers a cleaner and superior output compared to the Dragonfly Red. Don't worry Dragonfly Red, you're still one of my favorite dongles! At least in terms of build quality, aesthetics and sturdiness, you definitely have S9 Pro Plus beat.

vs Fosi Audio DS1
The Fosi Audio DS1 is a dark-horse among many choices in the budget dongle, it has what S9 Pro Plus has to offer except for the filters and firmware support that the S9 Pro Plus has at two and a "half-ish" times lesser the price. It is more robust, has volume support, and can support up to DSD512. It also sports the same ES9038Q2M ESS DAC. Spec-wise

CONCLUSION​

Pros:

• Neutral, clean, sound
• It has a 3.5mm and 4.4mm balanced port
• Provides plenty of power for both ports
• Has physical volume support
• Very portable

Cons:

• Cheap build quality
• The LED bleeding is a personal nitpick
• The filters have no drastic changes
• The USB type-C only works on specific orientations

We will be reviewing Hidizs's new planar in-ear monitors. Many have awaited Hidizs's planar earphones and led me to think, is it worth the hype it deserved? Let's find out!

I have my own share of experiences when it comes to planar in-ear monitors, I have tried the LETSHUOER S12 Pro, TANGZU Zetian Wu, MUSE Hi-Fi Power, and the KZ X HBB PR2.I am hoping that I could share my insights with Hidizs's new in-ear-monitor.

PACKAGING​

The packaging of the Hidizs MP145 has the typical Hidizs style, featuring the brand's logo and a preview image of the IEM on the sleeve. Notably, the box is crafted from plastic, which represents a different approach from their standard packaging materials. However, this choice raises concerns about the durability of the packaging during transit, as plastic tends to become brittle and may break if mishandled. Nonetheless, it has effectively safeguarded the item during shipping.


Upon opening the box, the contents appear to be neatly organized and straightforward. Here's what you'll find inside:

• HIDIZS MP145 drivers
• 3.5mm cables
• 3 pairs of bass eartips
• 3 pairs of vocal eartips
• 3 pairs of balanced eartips
• 3 pairs of tuning nozzles
• Leather earphone pouch

It's worth mentioning that the included leather earphone pouch may not be personally useful for those who find the earphones rather bulky. The pouch may not provide as effective protection as a dedicated earphone case would for these particular earphones.

BUILD QUALITY​

The MP145 Driver is built like a robust tank, boasting both bulkiness and sturdiness, which certainly catches the eye due to their bulky build. However, in my personal experience, I've found the fit of the MP145 to be uncomfortable, primarily because the included eartips don't align well with the MP145's nozzles.They fit excessively snug, requiring substantial effort for removal. Consequently, I opted for my TRI Clarion eartips, which feature larger bores and fit the MP145 perfectly, like a glove. It would have been beneficial if Hidizs had conducted some thorough testing to ensure a more comfortable fit with the provided eartips.The cables are okay, but these are not modular and only comes with the 3.5mm plug.

SOUND​

The sound profile of the HIDIZS MP145 plays around the U-shaped sound-signature, and may still vary depending on the nozzle used. However, it's clear that the HIDIZS MP145 tends to lean towards a warmer sound signature while making an effort to maintain a sense of neutrality.

BASS
The bass delivers a commanding punch and subtle yet resonant rumbles while exhibiting excellent control and swift transient response. It maintains its distinct character without bleeding into the midrange, providing a sense of power and coherency. The primary emphasis here is on resolution, impactful punches, and swift attacks, rather than focusing on deep-reaching bass weight. As a result, it may not be the preferred choice for those passionate about deep bass.

MIDS
The midrange exhibits a subtle recession, enriching male vocals with added depth, while female vocals adopt a more mature and euphonic timbre. Vocals maintain a pleasing and natural presence, avoiding an overly distant or hollow quality. Instruments receive some attention, preserving their natural and uncolored tones without excessive vividness. The upper-mids display a smooth, subtle gain with a non-fatiguing sound, making it especially favorable for individuals sensitive to harsh frequencies.

TREBLE
The treble performance falls somewhere between not being exceptional and not being subpar. It carries a remarkably inoffensive and smooth timbre. It's worth noting that some listeners might perceive the treble as lacking in energy and sparkle, which is entirely understandable. This characteristic is different from the typical planar earphones that often exhibit a distinct "planar" timbre, emphasizing the higher frequencies, but occasionally resulting in a shouty or shrill quality. Still, the treble is no slouch, it still has good precision and attention to details while subtracting the issues surrounding some "planar" earphones.

TECHNICALITIES
As far as technical aspects are concerned, this isn't somewhat groundbreaking but it is above average with decent soundstage with enough width, height, and depth that are spacious enough for my head room. It demonstrates a commendable separation and layering, allowing me to discern well-organized layers for each instrument. It adeptly handles complex tracks with ease, boasting excellent resolution and respectable detail retrieval.

TEST TRACKS​

DISCLAIMER: For my testing purposes, I don't use Spotify. I have high-resolution copies of my test tracks, maintaining a backup copy of these playlists on my Spotify account as a reference in case I lose my playlist.

CONCLUSION​

Pros:

• Excellent balanced sound
• Tuning filters offers slight but noticeable changes to cater your preferences
• Build quality is outstanding
• Thick, commanding bass
• Lush and euphonic mids
• Inoffensive treble
• Decent technicalities
• For $199, these are okay

Cons:

• They are BIG
• May have fitting issues for smaller ears
• Eartips are very incompatible and can be an effort to remove
• Earhooks are ANNOYING
• Needs decent sources to perform effectively

The oversized design may pose challenges for individuals with smaller ears, and the nozzles provide a secure grip with the eartips, making them somewhat challenging to remove, especially if you frequently have a rotation of eartips. If these aspects are not problematic for you, these IEMs are visually striking. Their balanced sound, with the option to make slight adjustments using the nozzles, positions them as a strong contender in the sub-$200 IEM category.

We are set to review KBEAR's newest bullet earphones, which boast a strikingly sleek design featuring a single-DD driver and shell made from Rosewood.

DISCLAIMER:​

• I have no affiliation with KBEAR and have not received any monetary compensation during or after writing this review. Keephifi provided this unit to me in exchange for an honest and unbiased review.
• As a non-professional reviewer, I aim to use simple terms that can be understood by both beginners and experts in the hobby.
• Please keep in mind that the opinions expressed in this review are subjective and based on my personal experience with the unit. I encourage you to try the product yourself to form your own opinion.

PACKAGING​

The packaging is very straightforward. Inside the box, you get a case where everything is already included. Here's what we have inside the box:

• KBEAR KW1
• 6 pair of eartips
• Case

BUILD QUALITY​

Wooden shells are a rarity in budget earphones, but KBEAR KW1 has achieved this distinction. Typically, earphone shells are crafted from resin, metal, alloy, or a hybrid of these materials. Witnessing something distinct like wood is undeniably refreshing. The KBEAR KW1 offers two versions: the 3.5mm variant, which I received from Keephifi, and the DSP variant. It's important to highlight that the KBEAR KW1 features a non-removable cable, and at a price point of $35, this aspect might be a deal-breaker to some. It has a microphone at least!

SOUND​

The KBEAR KW-1 stands as a bass-heavy earphone, boasting a satisfying punch that accompanies a dark tonality.

BASS
This is the star of the KBEAR KW-1: its bass is both impactful and punchy, characterized by swift attack and brief decay. Despite its bass-heavy nature, it maintains clarity and control, avoiding any muddiness as much as possible in its sound profile.

MIDS
There is a noticeable midbass bleed present, which leads to a somewhat obscured midrange. Vocals lack the engaging and euphonic quality one might hope for. Instruments like guitars come across as somewhat lacking to me. My initial expectation of a vibrant and natural quality is unmet, resulting in a rather unremarkable sound.

TREBLE
The treble lacks resolution and airiness. Given the earphone's bass-heavy nature, I expected a compromise in the treble performance. It lacks a distinct bite and energy and somewhat projects a subdued quality. Essentially, when the track isn't rich in bass, the overall sound tends to lack a certain depth of flavor. No traces of sibilance or harshness are observed when listening to these earphones.

TECHNICALITIES
This is a no brainer, and typically, bullet earphones tend to fall short in terms of technical capabilities. The soundstage, in this case, is fairly average, presenting itself in a rather two-dimensional manner. It lacks notable depth and immersive qualities, ranking as average at best. The imaging capability is also middling, although it does succeed in establishing a sense of placement for both vocals and instruments.

TEST TRACKS​

CONCLUSION​

Pros:

• Passable as a bass-focused earphone.
• The rosewood material looks sleek and sturdy.
• Inoffensive sound with less piercing details.
• Can be immersive if bass is present.

Cons:

• Treble almost sounds muted.
• Veiled mids.
• Dark sounding profile might not appeal to everyone.
• For $35, cheap consumers might want to ask for a removable cable (me included).
• Not the best in terms of technicalities.

The KB EAR KW-1 exhibits a dark sounding profile which offers elevated engaging lower frequencies but suffers from retrieving finer details. Dark sounding earphones tend to be more extreme for some and tends to be less popular than U-shaped sound profiles. If you prefer an extremely warm sound with not a care for those fine details, then the KB EAR KW-1 might be suitable for you. Then again, the fixed cable can be a deal breaker for some.

It is the first that I've heard of this Chi-Fi company and this is definitely the first that I am going to review their products. Keephifi has sent me the ND DD3 to seek my opinion on this earphone.

DISCLAIMER:​

• I have no affiliation with ND and have not received any monetary compensation during or after writing this review. Keephifi provided this unit to me in exchange for an honest and unbiased review.
• As a non-professional reviewer, I aim to use simple terms that can be understood by both beginners and experts in the hobby.
• Please keep in mind that the opinions expressed in this review are subjective and based on my personal experience with the unit. I encourage you to try the product yourself to form your own opinion.

PACKAGING​

The packaging is mostly basic with a pouch, set of eartips, the cables and the IEMs itself. I won't write too much on this one. What you see on the picture is what you get.

BUILD QUALITY​

The construction of the ND DD3 mirrors the typical quality found in most budget Chi-Fi IEMs. It features a blend of materials: a metal faceplate with a matte finish, coupled with a resin build for the rest of the shell. The connectors employ a QDC type connection, which is unsurprising given its prevalence as a standard connection in the realm of budget Chi-Fi. Generally, I appreciate the color scheme, with the exception of the rather obnoxious guitar design that unfortunately detracts from the overall aesthetic appeal of the product.

SOUND​

The ND DD3 features a tuning switch which doesn't feel that much of a difference in terms of sound. Out of the box, the ND DD3 presents a V-shaped sound signature as its default audio profile.

BASS

The bass carries considerable weight, particularly in the sub-bass region, delivering deeply satisfying rumbles. However, it lacks a bit of mid-bass punch, which results in a less defined and resolving bass impact. In certain tuning configurations, it can become quite muddy. Turning the switch "down" on the "ON" label somewhat fixes the muddiness in the bass, although the improvements are hardly discernible.

MIDS

Straight out of the box, the midrange presents a recessed presentation. The timbre in this range may appear unnatural, with a distinct metallic tone in the upper midrange. While vocals are placed more prominently, they may not sound entirely natural and can occasionally overshadow the instruments.

HIGHS

Although the treble region occasionally exhibits a metallic and unnatural quality, it can be tolerable on certain occasions. When the "ON" switch is off, the treble offers sufficient energy to bring cymbal splashes, piano keys, and saxophone to life, infusing them with a sense of vibrancy. However, with the "ON" switch on treble extension may recede somewhat, trading off some treble quality to accommodate the lower frequencies.

TECHNICALITIES

The soundstage and imaging are rather unremarkable, lacking any standout qualities. The soundstage can occasionally feel somewhat constricted and lacks a sense of expansiveness. While imaging can be decent, it faces challenges with complex tracks, making it difficult to discern micro-details. However, it's important to keep in mind that these are budget earphones, and such limitations are to be expected.

Here are my observations regarding the switches, although it's possible that you may not discern any differences. Upon critical listening, here are the outcomes I've noticed. Please keep in mind that these observations are based solely on my own perception. Ideally, there will be more comprehensive resources, like squigs, available in the future for a more technical and precise reference.

With the "ON" switch on/up:

• Low-res.
• More focused on the lows.
• Mids can sound boxy.
• Lacking treble presence.
• Compressed soundstage.

UUU

• Dark sounding
• Elevated bass and forward mids with weak treble presence

UDU

• Almost the same as UUU but the midrange is more recessed.

UDD

• Bass is lighter.
• Recessed mids with boxy vocals.
• Treble sounds muted.
• Probably the worst configuration in my opinion.

With the "ON" switch off/down:

• Has more balance.
• Treble has more presence.

DUD

• bass is more balanced.
• mids are much defined despite having a recessed quality compared to when the switch is on

DUU

• The most balanced configuration.

DDU

• higher frequencies are emphasized.
• a bit better soundstage.

CONCLUSION​

Pros

• Fun and lively sound.
• Nice color scheme.
• Good package inclusions but the pouch can be less effective when protecting the IEM.
• Good bass weight.
• Treble is lively.
• Cheap.

Cons:

• Upper frequencies can sound unnatural.
• Switches are gimmicky.
• Vocals can sound unnatural and boxy at times.
• Average technicalities.

It may be premature for me to make a definitive judgment on ND's potential, but my initial impression of their DD3 model hasn't convinced me that this company is poised for significant growth. However, I'm open to the possibility that they could improve over time. At best, I foresee ND becoming a dark horse contender, akin to Lafitear and CVJ.

While the ND DD3 doesn't stand out as an exceptional earphone, it does provide an enjoyable and lively listening experience for casual users. Aesthetically, I appreciate the earphones' overall color scheme, certain design elements, like the random guitar in the middle, should be reconsidered for their upcoming product lines since I find it distasteful and random, I might even try to scratch out the guitar design once I'm done with this review. It somewhat reminds me of the TFZ S2 Pro with its random teddy bear design and the letter "T." As for the tuning switches, it is another gimmicky feature that bears no significant changes to the sound unless you critically perceive it. Overall, a budget earphone is a budget earphone, you basically get what you pay for with no exceptional experiences, the ND DD3 is one example.

We have another in-ear monitor to review from LETSHUOER and its the EJ07M. This mid-tier is not their latest entry and has been released somewhere in 2021. For $650, will it be a worthy purchase?

DISCLAIMER:​

• I have no affiliation with LETSHUOER and have not received any monetary compensation during or after writing this review. This unit is provided to me in exchange for an honest and unbiased review.
• As a non-professional reviewer, I aim to use simple terms that can be understood by both beginners and experts in the hobby.
• Please keep in mind that the opinions expressed in this review are subjective and based on my personal experience with the unit. I encourage you to try the product yourself to form your own opinion.

PACKAGING​

The packaging of the LETSHUOER EJ07M is quite large for an in-ear monitor, while its inclusions have the basics. Inside the box, you'll find a top-tier protective case, an assortment of 6 pairs of eartips, 3 pairs of memory foam tips, the cables, and, of course, the core IEM itself – the EJ07M driver.

BUILD QUALITY​

In terms of build quality, I'm impressed by the EJ07M's lightweight design and its captivating color scheme, which adds a pleasing aesthetic touch. It has a recessed 2-pin which adds more durability to the pins. The included eartips and cables come across as somewhat cheap. On a positive note, the case displays a robust and high-quality appearance.
The Letshuoer EJ07M showcases a tribrid configuraton, incorporating a 10mm dynamic driver to manage the lower frequencies. The midrange and high-end is managed by Sonion drivers. And as we know, Sonion drivers are often found on mid-range to high-end products which really speaks for EJ07M's quality.

SOUND​

The sound profile of the EJ07M offers a well-balanced sound signature, adhering to the Harman target.

BASS
The EJ07M boasts a well-balanced bass presentation with commendable coherency. While a subtle midbass thump is noticeable, it has a nuanced and polished texture rather than an overwhelming impact. The sub-bass has substantial depth and satisfying thickness. This quality contributes a weighty feel to the bass when required, yet it can also recede when not necessary due to the reduced emphasis on midbass frequencies.
MIDS
The midrange exhibits a subtle recession, which in turn provides a warm and authentically natural midrange presentation, albeit at the expense of some intricate details. Vocals possess a euphonic quality and boast a notably rich texture. The upper-midrange frequencies have a safe tuning, preventing upper-pitched vocals from sounding overly sharp. This tempers the prominence of instruments, resulting in a lack of excessive brilliance. Notably, the absence of an aggressive bite in elements like trumpets and vocals can lead to slightly underwhelming execution. Overall, this lack of details on the midrange doesn't bother me that much since I like my midrange leaning to a natural and euphonic sonic profile rather than a forward and detailed one.
TREBLE
As the EJ07M closely resembles the Harman tuning, its treble is toned down to provide an enjoyable and more restrained treble response, all while maintaining a sense of definition. This measured approach leads to a gentle and soothing treble that avoids any harshness or edginess. This lack of emphasis result in a certain softness and bluntness to the treble. Instruments present in the treble experience a lack in shimmer and energy sometimes making some tracks focused on cymbals, trumpets, and piano sounding dull and lacking a bit of definition.

TECHNICALITIES​

Turning to the technical aspects, the EJ07M showcases an above-average soundstage. This spatial quality is marked by expansive dimensions in both width and height. Impressively, the imaging capabilities of this midrange in-ear monitor stand out, offering remarkable precision and accuracy in rendering the arrangement and positioning of instruments across the soundstage. The imaging possesses a sense of fluidity and remains unburdened by any sensation of compression, allowing it to unfold freely.

TEST TRACKS​

DISCLAIMER: I use the high-quality versions of these tracks on reviewing. This is only a compilation of my test tracks on Spotify. And hey, a media player looks very appealing on my posts don't you agree?

CONCLUSION​

Pros:

• Excellent, balanced sounding in-ear monitor that caters majority of listeners
• Has a good aesthetic appeal
• Easy to drive
• Imaging is excellent
• Excellent packaging
• Safely-tuned treble

Cons:

• Not for bass heads and trebleheads
• A modular cable could be a good addition for more flexibility

Purchasing the EJ07M at a price point of $600 might be considered a daring leap, especially without prior audition, but I can offer some reassurance that its tuning is quite safe and versatile, catering to a broad range of listeners. However, it might not be the best fit for bass enthusiasts or those seeking an exuberantly energetic treble. In terms of sound quality, packaging, and build, the EJ07M appears to be a solid choice. LETSHUOUER has presented several products that have garnered my approval, and the EJ07M seems poised to join their ranks. Also, there are some that I also disliked, ehem D13.

I am thrilled to review another true wireless in-ear monitors. It has been a while since I reviewed TWS set. This time, we are going to review the Hifiman Svanar Wireless. It is also the first of its own to use an R2R DAC in each pair. The SVANAR Wireless uses the HIMALAYA which stands as a refined 24-bit DAC (Digital-to-Analog Converter), distinguished by its utilization of the R2R architecture. This design is highlighted by an FPGA (Field Programmable Gate Array) chip, intricately composed of an array of resistors.

DISCLAIMER:​

• I have no affiliation with HIFIMAN and have not received any monetary compensation during or after writing this review. This unit is loaned to me by Auricular Remedy and this will be an honest and unbiased review.
• As a non-professional reviewer, I aim to use simple terms that can be understood by both beginners and experts in the hobby.
• Please keep in mind that the opinions expressed in this review are subjective and based on my personal experience with the unit. I encourage you to try the product yourself to form your own opinion.

PACKAGING​

The packaging appears quite simplistic, yet regrettably underwhelming. The provided eartips are cheap and uncomfortable to use, especially to my sensitive skin, and there is a noticeable absence of instructional materials regarding the product's usage. However, they do offer an online manual on their official website, accessible here.



What's inside the box:

• SVANAR TWS and Wireless Charging Case
• 5 pairs of silicone eartips
• 2 pairs of foam tips
• USB Type-C cord

BUILD QUALITY​

The build quality of the TWS case is rather questionable since it uses a somewhat plasticky design but it has a cool and sophisticated geometric design which makes it very modern looking. The in-ear monitors showcase a unique and attention-grabbing design, yet they are not without their imperfections. The faceplate features a silver plastic shell, and given the price point of $500, an alloy shell might have been a more premium choice. The inner section of the shell adopts a carbon-fiber-like pattern, but the nozzles are notably short, which could potentially be a problem to longer stemmed in-ear monitors. Additionally, the mesh appears rather inexpensive, reminiscent of what you might find on low-cost Chi-fi in-ear monitors, no offense intended. The tactile region on the shell is conveniently discernible by touch and offers impressive sensitivity, but it can be annoying since the touch panel is not capacitive, meaning it responds to anything other than the electrical flow of our body parts. From my personal experience, the fit is rather uncomfortable for me as it causes discomfort in the tragus area of my ear. These TWS has an IPX5 rating, signifying their water and sweat resistance.

CONNECTIVITY AND CONTROL​

For additional details regarding the controls, please refer to the online manual.

While the controls offer high precision, the touch control mechanism can be quite bothersome due to its non-capacitive nature. For instance, when lying on your side in bed, it might inadvertently pause the currently playing music. The SVARNA provides fundamental playback controls, although it does not include a volume control feature.

In terms of connectivity, the AAC and SBC connections are pretty much stable and has good bandwidth and stability. The concern emerges specifically when using the LDAC mode, as there might be potential issues during mode transitions or while physically moving. Throughout my experience with the SVARNA, I've consistently encountered challenges such as disconnections, sudden pauses, and sporadic audio playback limited to just one side. Undoubtedly, this problem stands as a considerably significant drawback. Hifiman is very transparent about this issue since they have a warning label on the box and manual about the consequences in using LDAC mode.

CODEC SUPPORT​

I'm using my Sony XZ1 Compact, which features APTX and APTX HD support. Yet, upon attempting to switch to the APTX codec, it consistently reverts to LDAC. The device does have support to LDAC, AAC and SBC, albeit restricted to these options.

MODES​

The Svanar has three modes, the Hi-Fi mode is the default configuration outside the box.

• High Fidelity
• Transparent Mode
• Active Noise Cancellation mode

To be honest, my experience left me quite disappointed, as these modes failed to make a significant impression on my listening encounters. The transparency mode of the Svanar is less than commendable, as it doesn't effectively amplify ambient noise, leaving me with the sensation that I still need to remove my earphones to grasp my surroundings. While it does capture some minimal ambient sounds, its performance is rather limited. Comparatively, the transparency mode of the Samsung Buds 2 Pro, although not perfect, is notably superior to the Svanar. When I first engaged the transparency mode on the Buds 2 Pro, I noticed a considerable improvement in my ability to hear my surroundings better while wearing them. The ANC did nothing better as well as it only recessed the sound rather than cancelling environmental noise. While the ANC mode doesn't provide exceptional isolation, it does offer a modest level of noise reduction in contrast to the approach of maximizing the volume in Hi-Fi mode to block environmental sounds. It manages to fulfill its purpose to a certain extent, although it doesn't particularly stand out in this regard.

SOUND​

The Svanar Wireless has a balanced sound-signature which sounds energetic, and natural.

BASS
The bass carries a rich, full-bodied texture with a well-balanced tonality, offering a substantial amount of sub-bass presence. While the midbass lacks forceful, impactful punches, the pronounced sub-bass delivers a satisfying experience. It demonstrates versatility, capable of diving deep when required or maintaining a more subtle presence.

MIDRANGE
The midrange is subtly recessed, yet it emanates a warm and natural tonal quality. Both male and female vocals possess a euphonic resonance. Instruments are not snappy, yet they do have a respectable level of detail.

TREBLE
The treble maintains a secure and laid-back nature. It avoids any harshness or sibilance while encompassing a pleasant sense of spaciousness. This quality makes it suitable for extended listening sessions. I just can't use this comfortable without finding the right snug fit and usually hurts the tragus area of my ear.

TECHNICALITIES
Considering its $500 price tag for a true wireless setup, the soundstage leaves much to be desired. While it presents average width and height, it manages to avoid sounding congested or messy. The imaging remains accurate, displaying smooth panning that ensures every element occupies its appropriate position on the stage. The resolution is commendable, as there is no discernible distortion regardless of whether you increase or decrease the volume.

TEST TRACKS​

CONCLUSION​

​

PROS:

• Excellent balanced sounding TWS
• Natural and energetic tonality
• Elegant design
• Commendable battery life
• It has the capacity to accommodate various sizes of ear tips within the charging case.

CONS:

• Uncomfortable fit (personal)
• Plastic materials used are quite disappointing for $500
• No volume controls
• No APTX Support
• Not a fan of its ANC and Transparency mode
• The charging case is bulky and not easily pocketable
• No instruction manuals, you'll have to search for it online

While the Hifiman Svarna has an excellent sonic performance, unique design, and commendable battery life. However, its features and overall quality is quite lackluster, despite its unique design. At a cost of $500, I find myself investing in an R2R technology that doesn't hold much relevance or uniqueness for a casual user like myself, and its unstable connectivity which is a very critical and concerning issue. The various modes fail to excel in their intended functions, and the ergonomics leave much to be desired. The inclusions provided are notably minimal and basic in nature. For me, the cons outweighs the pros and paying this much for a TWS is risky. It's really hard to say at this standpoint if I would recommend the Svarna. In my personal perspective, I wouldn't consider spending over $200 solely for the sake of hi-fi audio in a true wireless setup. Instead, I would lean towards exploring options within the sub-$200 range for a true wireless solution. However, despite its imperfections, this marks the inaugural R2R True Wireless product, and Hifiman has exerted considerable effort to incorporate this innovative wireless solution. I am confident that their future iterations could yield even better results, with the potential for the Svanar Wireless to serve as a significant milestone in their progress.

HIBY gave us the opportunity to review another top-of-the-line contender in the Chi-Fi market. This is the HIBY Zeta. Zeta is the sixth letter of the Greek alphabet. I don't know the meaning of their naming convention but sure, whatever works, right? I mean, Chi-Fi has their fair share of weird names, Zeta is a much suitable name for a TOTL in-ear-monitor.

DISCLAIMER:​

• I have no affiliation with HIBY and have not received any monetary compensation during or after writing this review. HIBY provided this unit to me in exchange for an honest and unbiased review.
• As a non-professional reviewer, I aim to use simple terms that can be understood by both beginners and experts in the hobby.
• Please keep in mind that the opinions expressed in this review are subjective and based on my personal experience with the unit. I encourage you to try the product yourself to form your own opinion.

PACKAGING​

The packaging of the HIBY Zeta is very generous and straightforward. Here's what's inside the box:

• HIBY ZETA in-ear-monitors
• 4.4mm cable
• 3 pairs of narrow bore eartips
• 3 pairs of hybrid eartips
• 3 pairs of silicone eartips
• Leather case

BUILD QUALITY​

Undoubtedly, the ZETA in-ear monitor boasts a sturdy and imposing appearance. The full-titanium design, with HIBY's logo intricately carved on it, stands out remarkably and adds a touch of uniqueness. The cables are very sturdy and somehow fits well with the in-ear monitor. I would've preferred an all-gray colorway for a sophisticated and neutral look but a royal blue cable complements it as well since gray is a neutral color, it will go well with any cables.

SOUND​

The HIBY ZETA features a captivating V-shaped sound signature that truly showcases its status as a top-of-the-line in-ear monitor. I need to point this out that this V-shaped signature is incredibly addictive. Initially, when I tried out the ZETA, they didn't strike me as anything special, just another typical V-shaped in-ear monitor. However, the more I listened to them, the more they grew on me, becoming quite addicting.

Personally, I have grown tired of this sound signature since it is quite common in the Chi-fi market, especially within the budget scene. Despite that, the ZETA's rendition of the V-shaped signature manages to stand out and appeal to those who appreciate this type of sound.

BASS
The bass on the HIBY Zeta delivers a powerful and dynamic punch that adds a fun and impactful sound. It manages to avoid being overly bloated or muddy, showcasing its impressive clarity despite the heavy sounding bass. Even with its power, the bass doesn't overshadow the midrange; instead, the midrange maintains its clarity and presence. Unlike many other bass-heavy options that sacrifice quality for dynamics, the HIBY Zeta excels in retaining excellent resolution while offering a thick and impactful bass response.

MIDS
The midrange of the ZETA strikes a perfect balance, sitting neither too forward nor too recessed. Despite the presence of thick and impactful bass, the midrange retains its clarity and smoothness. There is lushness and warmth with the vocals and exude a rich, natural quality.

When it comes to instruments, the ZETA excels at delivering a very musical and realistic rendition but it may not be for everyone if you desire a more neutral presentation on the instruments. It takes a subtle hit in terms of separation and detail retrieval. Then again, the ZETA leans toward to a more fun and musical sound rather than a clinical one. The upper-mids showcase impressive resolving capabilities with good luster and controlled brightness without any signs of peaks or harshness.

TREBLE
The treble on the ZETA might not possess all the sparkles and shimmer that some seek for heightened detail and boosted higher frequencies. Instead, it plays a safer role, offering a smoother and more controlled presentation compared to sharper and edgier highs. However, the resolution remains impressive and satisfying, especially for those who appreciate a more subtle treble punch.

The Sonion ESTs included in the driver configuration of the ZETA handle the higher frequencies, contributing to the overall treble performance. Personally, I find the treble to be just right for my tastes, striking a balance where it never sounds too harsh or fatiguing during extended listening sessions.

TECHNICALITIES
The soundstage of the ZETA falls within the average range in terms of width, height, and depth, yet it provides ample room for an impressive performance and sound separation. Despite its V-shaped sound signature, the ZETA demonstrates strong technical capabilities, allowing it to handle busy tracks without compromising resolution, while maintaining good separation between various elements.

The imaging on the ZETA is well-balanced between the left and right channels, enabling clear distinction of the instrument's location within the soundstage. This aspect adds to the overall immersive listening experience, providing a sense of spatial awareness and depth. You'll usually hear these resolving details on a neutral set, but HIBY managed to handle the technicalities well on their fun sounding boi.

TEST TRACK​

CONCLUSION​

Pros:

• Very addicting V-shaped sound that grows on you
• Midrange is still satisfying despite the emphasis on the lower region
• Treble is safely tuned, it is not sharp or edgy
• Very robust and durable build

Cons:

• Mids are not the most engaging experience
• Technically capable, but not TOTL grade technicality
• Treble might not satisfy trebleheads
• Cables could go for a modular approach to those who wants a more flexible option

Would I recommend the ZETA? If you are a musician or sound engineer seeking a top-of-the-line in-ear monitor for professional use, the ZETA might not be my top choice. I would instead suggest considering a custom in-ear monitor or a neutral pair that caters better to your professional requirements.

However, if you are someone with a budget for a fun and musical in-ear monitor, the ZETA could be a satisfying option to explore, because it's really addicting (real). Keep in mind that it might be a risky purchase for some, as it comes with a higher price tag that not everyone can afford. Personally, I find the ZETA appealing, and I would definitely consider buying it if I had the financial means to do so.

One aspect to consider before making a purchase is the lack of customization options in the package. The inclusions provided with the ZETA are good, but you won't have much flexibility in adjusting the sound to your liking outside of the box. Additionally, there's no option to swap out the cables, which can be a limiting factor to some. These factors should be taken into account when deciding whether the ZETA is the right fit for you.

LETSHUOER D13 - SIMPLICITY AND SMOOTHNESS​

The LETSHUOER D13 is an in-ear monitor featuring a single 13mm dynamic driver, housed in a compact and comfortable shell. This is my fourth LETSHUOER product review. The D13 came out somewhere in 2022, a little bit late to the party but will it still be a good option for 2023? With the rapid and constantly evolving Chi-Fi market, let's find out if this is still a good option for 2023.

DISCLAIMER:​

• I have no affiliation with LETSHUOER and have not received any monetary compensation during or after writing this review. Ivy Gao provided this unit to me in exchange for an honest and unbiased review.
• As a non-professional reviewer, I aim to use simple terms that can be understood by both beginners and experts in the hobby.
• Please keep in mind that the opinions expressed in this review are subjective and based on my personal experience with the unit. I encourage you to try the product yourself to form your own opinion.

PACKAGING​

The unboxing experience of LETSHUOER always have that sleek, and sophisticated feel. The D13 is no exception. It also has a lot of good and quality accessories included in the package.





Here's what's inside the box:

• LETSHUOER D13 in-ear monitors.
• 4-core 3.5mm cable.
• 3 pairs of black-colored silicone ear tips.
• 3 pairs of translucent silicone ear tips.
• A black-colored faux-leather IEM case.
• An extra pair of tuning nozzles with gold-colored filters.
• A product catalogue booklet.
• Some cool looking paperworks.

BUILD QUALITY​

As for the build quality, the LETSHUOER D13 drivers are housed in a matte aluminum-alloy shell giving that lightweight, sturdy, smooth finish on the ends. The nozzles are very easy to change as you only need to unscrew the nozzles, as simple as that. Additionally, the LETSHUOER D13 features a flawless 2-pin port design that offers a secure and snug fit without any protrusion, distinguishing it from QDC-type ports.

The cables are soft and sturdy but these does not have modular options which are still okay for this price point. The stock ear tips are good as is, they are soft, comfortable, and not irritating to the ears. Lastly, the faux-leather case is very compact but the in-ear monitor fits well. It has a good curved finish so it fits comfortable inside your pockets.

SOUND​

The LETSHUOER D13 has a slight V-shaped signature. It has two tuning nozzles that doesn't have a stellar difference but I find the gold one more preferable for its focus on the treble side. The silver nozzle is kind of underwhelming in terms of brilliance.

LOWS
The LETSHUOER D13 showcases extended lows with a noticeable dominance on midbass, along with a modest depth in the sub-bass region. While it may not be overwhelmingly bass-heavy, the presence of the bass is definitely perceptible. If you prefer a greater emphasis on the bass, I'd stick with the silver nozzles. However, personally, I don't find any stellar differences between the two filters on the lower frequencies. Maybe because the perception of the silver filter's laid-back presentation contributes to the I find the gold filters more appealing as the silver nozzle feels somewhat too laid-back in comparison.

MIDS
The midrange of the LETSHUOER D13 exhibits a recessed quality that contributes to a smooth and euphonic sound. The vocals, particularly when using the silver nozzles, are laid-back, darker, and possess a richer tonality. However, the instruments take a recessed position in the silver filters. On the other hand, the gold filters maintain a recessed body in the midrange but offer more pronounced upper mids, resulting in improved instrument emphasis and improved clarity.

TREBLE
The LETSHUOER D13's filters have a significant impact on the higher frequencies, with more noticeable changes compared to the lows and lower midrange. Although both filters lack a considerable amount of openness, they still exhibit slight but distinct differences. With the gold filter, the sound from the upper mids to the treble range becomes crisper, more detailed, and cleaner. On the other hand, the silver filter offers a smoother and less offensive sound, albeit with lower resolution in the treble region. While I don't find the gold nozzle offensive, the silver nozzle doesn't align with my personal preferences. As someone who isn't particularly focused on treble, I find the silver nozzle's level of detail and air to be somewhat lackluster. Both filters don't exhibit harsh sibilance, and peaky resonance which is very outstanding.

TECHNICALITIES
The technicalities on the D13 is mostly on the average side. Then again, these are not a pair of critical in-ear monitors nor did they intend to sell as one. These are rather casual earphones meant to cater casual listeners. In any case, let's break down the technicalities further.

Soundstage: The soundstage is not very wide but it's not too compressed to the point vocals and instruments were struggling in a cramped narrow soundstage. However, the perception of space is quite limited.

Imaging: In terms of soundstage, if there is a lack of adequate space, imaging can be affected as well. The LETSHUOER D13 exhibits average imaging capabilities, managing to accurately locate vocals and instruments. However, it may struggle with accuracy, particularly on busier and complex tracks, occasionally resulting in a loss of details and resolution.

TEST TRACK​

CONCLUSION
​

Pros:

• Has interchangeable nozzles
• Fun sounding earphones
• Very smooth and natural tonality
• Amazing inclusions
• Gold nozzles are better sounding overall

Cons:

• Price-to-performance ratio
• Treble lack a bit of air and sparkle
• Subpar technicalities
• Could've added more options for the nozzles, the other one might be too bad you'll have to stick with the other one if you don't prefer the other
• Silver nozzles are too lacking in details

Even in 2023, the LETSHUOER D13 remains a viable option worth considering. However, I believe that in terms of both performance and affordability, there might be other options available that can rival the LETSHUOER D13. The price to performance ratio can likely be matched by alternative products on the highly dense and ever expanding Chi-fi market. The LETSHUOER D13 is something I wouldn't blindly buy, especially if I intend to spend more than a hundred dollars with this. Sure, it offers a sound profile that can satisfy the majority of consumers and delivers impressive audio quality. However, it is important to acknowledge that being a single dynamic driver IEM, it does have its limitations.

We conducted a review of the LETSHUOER S12 last year. Today, we will be discussing its successor, the S12 Pro, which is touted as an upgraded version. While the S12 Pro maintains most of its looks from its predecessor, it introduces a new colorway. How about the sound? Is it an upgrade, or just a sidegrade? We'll find out!

DISCLAIMER:​

• I have no affiliation with LETSHUOER and have not received any monetary compensation during or after writing this review. This unit is provided to me in exchange for an honest and unbiased review.
• As a non-professional reviewer, I aim to use simple terms that can be understood by both beginners and experts in the hobby.
• Please keep in mind that the opinions expressed in this review are subjective and based on my personal experience with the unit. I encourage you to try the product yourself to form your own opinion.

PACKAGING​

LETSHUOER always provides an exceptional unboxing experience, showcasing a level of professionalism that sets them apart from other Chi-Fi companies. While their competitors' unboxing experiences may seem random, weird, and barebones, LETSHUOER consistently delivers a well-curated presentation.



What's inside the box?

• LETSHUOER S12 PRO IEMs.
• Three pairs of black-colored memory foam ear tips.
• Three pairs of black-colored narrow-bored ear tips.
• Three pairs of transparent, balanced-bored ear tips.
• Faux-leather case
• Modular cable
• A 3.5mm termination plug adapter.
• A 4.4mm termination plug adapter.
• A 2.5mm termination plug adapter.
• Supporting documents such as an instruction manual, quality control certification, warranty card, and contact card.
• A product catalogue booklet. (This is very awesome, in my opinion)

SOUND​

The LETSHUOER S12 Pro takes on a U-shaped sound signature. Overall tonality is natural with a tiny evident bit of "planar sheen" on the upper frequencies. Still, this is a warmer set compared to other planar in-ear-monitors.

BASS
The LETSHUOER S12 Pro delivers bass with a swift attack and impressive dynamism, creating a remarkable impact. It is not very heavy, but the energy it resonates is very outstanding. The midbass carries sufficient weight, creating a thumpy and enjoyable texture to the overall bass response.

MIDS
The midrange of the LETSHUOER S12 Pro doesn't possess an aggressive, in-your-face quality, yet it offers a clean and euphonic representation of male and female vocals. Instruments exhibit a natural and intimate texture, providing a pleasant listening experience, especially on acoustic guitars.

TREBLE
Treble heads will rejoice because they'd be delighted to know that the LETSHUOER S12 Pro provides an ample amount of air and energy in the treble range. It is not excessively bright or harsh, striking a balance that allows for detailed and crisp sound reproduction.

TECHNICALITIES
Soundstage: It boasts a wider soundstage compared to other in-ear-monitors within its price range. It creates a spacious sound field that allows instruments and vocals to breathe and perform with ample room.

Imaging: It exhibits an impressive ability to accurately locate various instruments and vocals within the soundstage. As expected from a planar in-ear monitor, it delivers a high level of precision and excels in reproducing complex tracks. The S12 Pro excel at presenting intricate details, allowing me to fully appreciate the intricacies and nuances of the music.

COMPARISONS​

LETSHUOER S12: Of course, why shouldn't we compare it to the OG S12? When it comes to the design and physical aspect, the S12 PRO is like a Copy + Paste of the original S12 and doesn't deviate much from its roots, it only changed its color from titanium silver to Corsican Blue . The sound is a bit more refined on the S12 Pro removing that excessive treble spike. Both set are still warm overall, and technicalities are almost the same.

KZ PR2: The PR2 features a V-shaped tuning, characterized by an energetic bass and vibrant treble, while the midrange takes a more subdued presence. On the other hand, the LETSHUOER S12 offers a more natural and preferable listening experience. The S12 is more balanced and has better technicalities compared to the PR2. Nevertheless, the other one still has an advantage over the other. Notably, the PR2 being two times cheaper than the S12 Pro is already an advantage.

TEST TRACK​

CONCLUSION​

Pros:

• Excellent, thumpy bass
• Natural-sounding vocals
• Crisp, airy treble
• Modular cables.... at this price point? Not the first, but yes!
• It's very easy to drive

Cons:

• I believe it only has one colorway
• Bass could use a bit more texture
• Not a huge leap to the original S12

The LETSHUOER S12 Pro found its place as a remarkable in-ear monitor within the sub-$100 budget range. With its modular cable, exceptional sound quality, and impressive inclusions, it offers a compelling package that you might want to consider. It is highly efficient and can be effortlessly driven by smartphones or digital audio players, making it a convenient choice for portable audio setups. The S12 Pro strikes a great balance between affordability, performance, and ease of use, making it an excellent option for budget-conscious audiophiles.

The company DUNU has been around for a while. A company hailing from China, they have released a few good in-ear monitors over the past few years. This is their latest offering, the DUNU SA6 Mk2. The DUNU SA6 Mk2 uses a 2nd generation. 6 balanced armature drivers and has a dedicated switch that noticeably enhances the lower frequencies and makes the overall sound more thicker and immersive.

DISCLAIMER:​

• I have no affiliation with DUNU and have not received any monetary compensation during or after writing this review. HifiGo provided this unit to me in exchange for an honest and unbiased review.
• As a non-professional reviewer, I aim to use simple terms that can be understood by both beginners and experts in the hobby.
• Please keep in mind that the opinions expressed in this review are subjective and based on my personal experience with the unit. I encourage you to try the product yourself to form your own opinion.

PACKAGING​

The packaging feels premium and includes many premium inclusions as well. I noticed lately that some Chi-Fi companies started to charge us lots of money for just the sound without considering the inclusions. And as a consumer, packaging is really important.












----- SKIP THIS PART IF NOT INTERESTED -----


Let me add something unrelated since I really wanted some companies to notice their packaging. Consumers often form quick judgments based on their initial visual impressions. When they encounter a product, its packaging communicates a message to them. The packaging plays a crucial role in catching the eye and creating an inviting appeal. Furthermore, it greatly contributes to brand recognition. That is why I must commend DUNU for successfully bringing forth this premium package to me.

----- THANK YOU! -----

Anyways, enough of that here's what's inside the box:

• DUNU SA6 MK2 in-ear monitors
• Candy-like eartips
• Leather case
• S&S eartips (God-tier eartips btw!)
• Regular silicone eartips
• Modular cable with 3 terminations (3.5mm, 4.4mm, 6.3mm jacks)

BUILD QUALITY​

The DUNU SA6 MKII exhibits a CIEM form factor made with a resin build, which I find particularly comfortable, especially when paired with the high-quality S&S eartips. This in-ear monitor utilizes a 6 balanced armature configuration. Additionally, the cable appears robust and high-end, it's a modular cable offering users a range of options to choose from.

SOUND​

The DUNU SA6 MkII has a rich, desirable, U-shaped signature decreasing the amount of midrange while making the lower frequencies thicker and treble smoother.

BASS
The bass has good texture and weight which I found surprising from an all-BA setup. Its dynamics and density are similar to what you would hear on a dynamic driver, except that this particular driver is an all-BA driver.. Turning on the switch makes the lower frequencies even more pronounced with sub-bass domination and less mid-bass thump.

MIDS
The mids exhibits a warmer tonality with rich and natural vocals. Female vocals, in particular, exhibit remarkable prominence, emotional depth, and warmth. However, there may be a slight lack of texture in male vocals. Overall, vocals never sounded shouty at all as the upper-mids are toned down in this IEM. Instruments, such as acoustic guitars, sound realistic, and natural without sacrificing clarity.

TREBLE
The treble of the SA6 Mk2 is characterized by its crispness and a sense of openness. It manages to deliver a lively and energetic presentation without sounding harsh or overly splashy. The treble's energy adds an exciting level of detail to the overall sound, ensuring that the SA6 Mk2 remains engaging and far from dull.

TECHNICALITIES
The SA6 Mk2 has an open width soundstage that greatly creates a holographic field that makes me feel like I'm in a huge stage. The instruments are everywhere in an organized manner. The depth of the soundstage is more of an in-your-face type and doesn't go that far inside the soundstage. Imaging is excellent even in complex tracks, the SA6 Mk2 excels at maintaining excellent instrument separation. Each instrument is distinct and discernible, allowing for easy tracking of individual elements within the music.

TEST TRACKS​

CONCLUSION​

​

Pros:

• All-BA Setup that has a very dynamic tonality
• Switches make the sound more meatier
• Decent technicalities
• Female vocals are emotional
• The bass is very outstanding for an all-BA setup
• Very good with any genre you throw at it
• Very generous inclusions

Cons:

• Personally, I can't find any negatives.

The DUNU SA6 Mk2 is an amazing in-ear monitor that utilized the usage of a switch and an all-BA setup to create a fun and exciting in-ear monitor without sacrificing some details. It also has a solid packaging and accessories making the SA6 Mk2 a worthy purchase.

CVJ TXS - TUNING SWITCHES FOR LESS​

CVJ gave me the opportunity to review their latest and probably the cheapest in-ear monitor with tuning switches. The CVJ TXS is a sub-$20 in-ear-monitor known for its gimmick tuning switches at an affordable price.

DISCLAIMER:​

• I have no affiliation with CVJ and have not received any monetary compensation during or after writing this review. CVJ provided this unit to me in exchange for an honest and unbiased review.
• As a non-professional reviewer, I aim to use simple terms that can be understood by both beginners and experts in the hobby.
• Please keep in mind that the opinions expressed in this review are subjective and based on my personal experience with the unit. I encourage you to try the product yourself to form your own opinion.

PACKAGING:​

The packaging is very straight-forward. You have the in-ear-monitors, a cable, three pairs of silicone ear tips, and some paperwork that you probably won't be using.

SOUND​

The TXS has a U-shaped sound signature but the tuning switches was supposedly be used in different kind of scenarios. They have three modes : Cellphone mode, gaming mode, and Hi-Fi mode.

Here is a guide regarding their tuning switches:



Sources used:

• HIBY FC6
• LG G8
• HIBYR2 MkII
• Nintendo Switch (for Gaming mode, duh)

Game Mode (DU): This mode offers an immersive and crisp sound experience that works exceptionally well with the Nintendo Switch. While the other modes may result in less immersive sound on the Switch, the Game Mode truly enhances my gaming experience with it.

Cellphone Mode (UD or UU): This mode delivers an aggressive V-shaped sound signature, with a particular emphasis on powerful and dynamic bass. It is well-suited for those seeking a more intense and impactful audio experience, especially when using the IEM with a smartphone.

HiFi Mode (DD): The HiFi Mode takes a leaner, warmer, and balanced approach to the sound signature compared to the Cellphone Mode. It offers a more refined and accurate sound representation, making it an ideal choice for those who prioritize high-fidelity audio.

Best switch for overall sound: The HiFi Mode stands out as the optimal choice for achieving the best overall sound quality, thanks to its balanced and accurate presentation.

Best switch for gaming: Unsurprisingly, the Game Mode (DU) is the top recommendation for gaming, as it provides an immersive and crisp sound experience, specifically tailored to enhance gaming sessions.

Best for casual and fun listening: The Cellphone Mode (UD or UU) shines in casual and entertaining listening scenarios. Its aggressive V-shaped sound signature, with a powerful and dynamic bass response, creates an engaging and enjoyable listening experience.

The KE-S offers a modest level of impact and texture on the bass. It is slightly elevated and does not sound overpowering. Bass heads might not find the TXS appealing but it still offers good impactful bass.

Mids
The mids of the KE-S demonstrate a recessed quality. Despite this characteristic, the vocals remain well-balanced and retain a presence that avoids sounding excessively recessed. The upper-mids might sound a bit harsh to some tracks but it is free of sibilance.

Treble
The treble of the KE-S can be described as smooth and inoffensive. It exhibits an extended range, although it may lack some of the airiness found in other models. There is a modest level of energy and presence in the treble response. No hints of sibilance or peak are observed in this budget pair.

Technicalities
Soundstage: The soundstage of this IEM falls within the average range commonly found in budget models. It lacks the expansive and immersive quality found in higher-end options, resulting in a somewhat two-dimensional presentation. Even by tweaking the switch to Hi-Fi mode, it still retains the same stage compared to the other modes.

Imaging: Similarly, the imaging performance of this IEM is also average. It may struggle to provide precise separation and placement on busier tracks. However, considering its price point, it still manages to offer a decent imaging performance.

TEST TRACKS​

CONCLUSION​

Pros:

• Smooth U-shaped sound signature.
• Very affordable.
• Safe and inoffensive sound.

Cons:

• Switches don't have any stellar differences, but it varies on the source. I used multiple sources to spot the differences.
• Bass may be lacking to some.
• Average technicalities.

If you want the cheapest IEM with tuning switches, the CVJ TXS would be a good option to consider.

SOFTEARS STUDIO 4 - A PURE SONIC EXPERIENCE​

HifiGo just gave us the opportunity to send in another solid in-ear monitor. I am no musician, or expert in the music field but the Softear Studio 4 is one heck of an in-ear monitor. It is a quad-balanced armature IEM which is advertised to be designed for monitoring, musicians, and other activities that might benefit from its flat sound signature.

DISCLAIMER:​

• I have no affiliation with Softears and have not received any monetary compensation during or after writing this review. HifiGo provided this unit to me in exchange for an honest and unbiased review.
• As a non-professional reviewer, I aim to use simple terms that can be understood by both beginners and experts in the hobby.
• Please keep in mind that the opinions expressed in this review are subjective and based on my personal experience with the unit. I encourage you to try the product yourself to form your own opinion.

PACKAGING​

The packaging of the Softears Studio 4 is nothing interesting and the inclusions are barebones. While the sound quality might be impressive, I find it hard to justify the high price of this package. However, it does manage to cover the essentials without lacking or providing something grandeur.



What's inside the box:

• Softears Studio 4 in-ear monitor
• 3 pair of eartips
• 1 extension cable
• 1 3.5mm female to 6.5mm male
• 1 cable
• Cleaning brush
• Case
• Some paperworks

BUILD QUALITY​

The Studio 4 features a sleek and minimalist shell crafted from high-quality resin, giving it an elegant and polished look. There is nothing more for me to say, Softears just wanted to keep things simple and let the sound speak for itself.

​

​

SOUND
The sound of the Studio 4 might not appeal to the masses since it has its own niche market, primarily to cater the likes of musicians, sound engineers, singers, and etc. The Studio 4 has a clean neutral sound signature and I personally have a preference for warm sounding earphones; I pretty much enjoyed Studio 4's clean nd accurate performance.

BASS
The Studio 4 has excellent bass control, delivering a punchy and fast-attacking response when you need it. However, it's worth taking note that this is not an IEM known for its overwhelming bass and may sound lean to some listeners who prefer a meatier bass.

MIDS
The midrange has a pleasing, natural texture. It maintains an almost flat position in the sound spectrum, without feeling too forward nor recessed. The vocals come across as natural and clean, while instruments like acoustic guitars sound accurate, close to realism, good attack, and possess a subtle warmth in their texture. The upper mids never produced any unnecessary peaks or exhibit any harshness.

TREBLE
The treble is exceptionally smooth, safe, and non-fatiguing. Treble-heads may find the extension to be somewhat lacking in energy and air. Nonetheless, it manages to maintain clarity and impressive detail retrieval, even though it sacrifices some of the energy, airiness, and sparkle typically associated with more a pronounced treble.

TECHNICALITIES:
Soundstage: The soundstage has good focus on width and depth which did not sound poorly resolving and messy. It is wide enough to provide ample space for vocals and instruments without struggling on complex tracks that I tried with it.

Imaging: Vocals and instruments are easily distinguishable. Presentation and placement is very accurate which is very helpful in tracking down different elements on one track. This level of precision greatly assists experts, such as music engineers, in dissecting the different sounds present in an audio recording.

CONCLUSION​

Pros:

• Neutral sound signature
• Punchy bass
• Minimalistic design
• Outstanding technicalities

Cons:

• Barebone inclusions, eartips feel cheap specially for this price point
• May sound dry or lean to those who prefer a fun, meatier, sound profile

While I know to myself that I may not qualify to thoroughly evaluate these in-ear monitors for sound engineering and intricate audio tasks, I can certainly provide my insights as a reviewer. In my assessment, these in-ear monitors exhibit commendable neutrality. Although they may not achieve the same level of pristine and diffuse neutrality as the Etymotic brand, especially to the likes of . Overall, these in-ear monitors stand out as an impressive benchmark for discerning listeners who prioritize neutral sound and critical listening.

AFUL, a relatively young company founded in 2018, made its entry into the Chi-Fi market with their initial product, the Performer 5, which elicited mixed reactions from enthusiasts. While some praised its performance, others even made puns referring to it as the "AWFUL Performer 5." Today, we will be reviewing AFUL's latest offering, the Performer 8. Will this be better or nah?

DISCLAIMER​

• I have no affiliation with AFUL and have not received any monetary compensation during or after writing this review. This unit is provided by HiFiGo in exchange for an honest and unbiased review.
• As a non-professional reviewer, I aim to use simple terms that can be understood by both beginners and experts in the hobby.
• Please keep in mind that the opinions expressed in this review are subjective and based on my personal experience with the unit. I encourage you to try the product yourself to form your own opinion.

PACKAGING​

What's in the box?​

• AFUL Performer 8 IEMS
• Cable
• 6 pairs of silicone eartips (I did not include the other tips, it's a pain to take them all out)
• Some paperwork
• Faux-leather case

The packaging of the Performer 8 remains identical to its predecessor, the Performer 5. However, there is a distinct change in the color scheme, as the box now sports a sleek greyish-black hue. In terms of contents, the quantity and quality remain consistent, with one notable difference. The case included with the Performer 8 utilizes a faux-leather material. The case is also more spacious compared to the Performer 5. The included eartips continue to leave a sense of disappointment, giving off a cheaper and underwhelming impression for a product that carries a price tag of nearly $300.

BUILD QUALITY​

The shells are nearly identical to the Performer 5; in fact, without the model name on the shells, it would be difficult to discern any differences. However, the drivers are lightweight, which contributes to their overall design. Additionally, the cable appears to be sturdy and reliable.

SOUND​

The Performer 8 stands out with its natural and warm tonality, setting it apart from the Performer 5. It can effortlessly drive any device I connect it to, even managing to drive an old Nintendo DS without a hitch. Personally, I find this tuning preference preferable over the Performer 5 any day. While the Performer 5 offers thumpier bass, livelier vocals and an airy treble extension, the Performer 8 boasts a noticeable warmth, striking a well-balanced sound signature that proves versatile across different genres. It successfully avoids the harsh treble extension that I found displeasing in the Performer 5.

BASS
I would describe the lower frequencies as well-balanced, with neither overpowering the other. The sub-bass offers impressive depth and extension, while the mid-bass is tight and delivers a satisfying punch. The bass, as a whole, demonstrates decent dynamics and precision. However, it's worth noting that this is not a bass-heavy earphone, as the extension is mild rather than overwhelmingly heavy.

MIDS
The mids are pleasing and warm sounding. The vocals sound natural, rich, and immersive. They never sounded thin or too warm. At no point do they sound thin or overly warm, maintaining a euphonic timbre that allows an emotional and powerful performance on the vocals.

TREBLE
The Performer 8 has an outstanding treble reproduction. Compared to the Performer 5, the P8's treble has been noticeably improved and offers a much more pleasing touch to my ears. The treble has a smooth and delightful "zing" and "zesty" texture, reminiscent of the qualities found in Piezo or EST drivers.

TECHNICALITIES
The soundstage is not that spacious but it makes up for its outstanding performance, as it not only met but exceeded my expectations when it came to detail retrieval. The level of precision and clarity it provided was truly remarkable. Every intricate and subtle micro-details were captured with remarkable accuracy. The separation of the Performer 8 were commendable, allowing me to easily discern the precise position of individual instruments and vocals within the sound stage. In my observation, during busier tracks, like the "National Anthem" by Radiohead, I noticed a slight decrease in resolution with the Performer 8, which occasionally resulted in a slightly unrefined quality for certain instruments.

TEST TRACKS:
Lately, I've been neglecting to include my test tracks in my reviews. However, I have decided to change that moving forward and will once again include them in my reviews. I always use these test tracks initially on my reviews before I shuffle my playlist. I make sure that I handpick and research the best test tracks that covers all genres.

1. Dreams - Fleetwood Mac
2. Piano Concerto No. 2 in C Minor - Sergei Rachmaninov
3. National Anthem - Radiohead
4. Rehab - Amy Winehouse
5. Rainbow in the Dark - Dio
6. Das Spiegel - The Chemical Brothers
7. Helplessly Hoping - Crosby, Stills, Nash & Young
8. You've Got To Have Freedom - Pharoah Sanders
9. Uh Uh - Thundercat
10. Letters - Yosi Horikawa
11. Concierto de Aranjeuz (Adagio) - Miles Davis
12. Team Doing It Right - The Go!
13. Aphex Twin - Mookid
14. Blinding Lights - The Weeknd
15. The Four Horsemen - Aphodite's Child
16. Minerva - Deftones
17. The Pot - TOOL
18. Dry Fantasy - Mogwai
19. Give Life Back To Music - Daft Punk
20. Bubbles- Yosi Horikawa

CONCLUSION​

Pros:

• Decent balanced signature
• Non-offensice compared to Performer 5
• Tight bass texture
• Natural sounding mids
• Smooth, inoffensive treble
• Decent imaging
• Very easy to drive

Cons:

• Inclusions are underwhelming for $370 (at this price range, you have a set including modular cables, high-quality eartips, some cleaning tools, etc.)
• Lacking in midbass thump
• Average soundstage

For those seeking a slightly warm and balanced IEM within the sub-$300 price range, this option stands out as a superior choice. However, it's worth noting that some inclusions in the package such as the ear tips might give off a slightly cheaper impression. Nevertheless, swap this out with some better ear tips and you'll be good.

I must acknowledge and commend the significant improvements made in the Performer 8, which builds upon the foundation laid by its predecessor, the Performer 5. It is important not to overlook the fact that the Performer 8's excellence owes much to the advancements introduced in the Performer 5. The Performer 5 set the stage and provided the groundwork for the Performer 8 to excel and deliver an exceptional performance. The evolution from the Performer 5 to the Performer 8 showcases the continuous commitment to refinement and innovation, resulting in a truly remarkable product by AFUL.

KZ has recently introduced their latest in-ear monitor featuring planar drivers, the PR2. This model boasts an impressive 13.2mm planar driver configuration. As the successor to the PR1, which unfortunately I didn't get a chance to try, I am grateful that KZ has provided me with the opportunity to experience the PR2.

DISCLAIMER:​

• I have no affiliation with KZ and have not received any monetary compensation during or after writing this review. KZ provided this unit to me in exchange for an honest and unbiased review.
• As a non-professional reviewer, I aim to use simple terms that can be understood by both beginners and experts in the hobby.
• Please keep in mind that the opinions expressed in this review are subjective and based on my personal experience with the unit. I encourage you to try the product yourself to form your own opinion.

PACKAGING:​

While the inclusion of barebone accessories doesn't bother me in KZ's budget segment, I feel that for models like the PR2, it would have been a notable improvement to have a case and a better cable included. It's not surprising to see that the inclusion of accessories remains the same, regardless of whether it's a budget KZ IEM or a "flagship" model. However, I acknowledge that this is solely my personal opinion, and I hope that KZ considers such feedback moving forward.



What's inside the box?

• KZ x HBB in-ear monitors
• Cable
• 3 pair of starline silicone eartips
• 1 pair of memory foam tips
• Paperworks

BUILD QUALITY
I must praise KZ for their continuous commitment to improving the build quality of their in-ear monitors. The planar driver in the PR2 is housed in sturdy resin shells, reinforced with a metal faceplate. I personally would prefer if KZ started utilizing recessed 2-pins instead of the QDC type pins, particularly for their higher-priced models. Nevertheless, the overall build quality of the PR2 remains commendable.

SOUND​

The PR2, despite having planar drivers is not cursed/blessed with the so called "planar sheen". The PR2 showcases KZ's signature warm V-shaped sound signature, which has been a defining characteristic of their brand since its inception. Over time, they have continuously refined and improved upon this sound signature, making it even more enjoyable.



BASS
The bass response of the PR2 offers a moderately thick presentation, although it may not have the same level of impact as some of KZ's previous models like the ZAS. This distinction can be attributed to the PR2's use of a planar driver instead of a dynamic driver, which leads to a bass that is less dense and impactful compared to a dual-driver setup. The focus of the bass is primarily on the sub-bass frequencies, while the midbass has a lesser impact and thump in the lower frequency range. However, despite this difference, the PR2 still performs admirably in the lower region and can satisfy the preferences of some bass heads.

MIDS
The midrange presentation of the PR2 strikes a subtle balance between clarity and engagement, with a slight recessed quality. While the vocals may not possess the same level of euphonic richness and thickness typically found in warmer planar sets, they still deliver decent and clean vocals. Instruments, although not prominently pronounced, maintain clarity and exhibit good separation within the mix. Overall, the midrange of the PR2 delivers a smooth and acceptable musical performance, providing an enjoyable listening experience.

TREBLE
One notable surprise with the PR2 is its departure from the typical treble performance found in other KZ in-ear monitors. In the past, certain models from KZ were often criticized for having harsh and shrill treble. However, this issue is not present in the PR2. The treble is not excessively airy, but it still provides a commendable level of clarity expected from a planar IEM. While the PR2 offers a subtle touch of sparkle to certain tracks, it doesn't deliver an exceptionally vibrant brilliance. Nonetheless, the treble is commendable for its absence of harshness, shoutiness, and sibilance, which is definitely a positive aspect of its performance.

TECHNICALITIES
While the soundstage of the PR2 is not particularly expansive, it offers a decent sense of space considering its price range. The soundstage doesn't sound lacking or compressed, allowing the music to breathe and avoid feeling congested. In terms of imaging, the PR2 performs admirably, providing a clear sense of placement for instruments and vocals as they progress across the left and right channels. The separation between individual elements within the music is also commendable, even in busier tracks where multiple instruments and layers are present. Furthermore, the PR2 exhibits the ability to capture fairly subtle micro details, adding an additional layer of depth and nuance to my listening experience. The PR2 might demand more power to unleash its full potential. Then again, this is a $40 planar in-ear monitor but it fares decently on its own.

COMPARISON​

I don't have anything to compare against the KZ PR2 within its price range because I haven't been exposed that much to its potential competitor the Celest Gumiho which also houses a square-planar driver. I also can't compare it to its older brother the PR1 since I haven't tried it at all. However, I can try to compare it with much expensive planar sets I tried. It's important to note that these comparisons highlight the distinct strengths of each IEM, rather than determining which one is superior overall.

1. MUSE HiFi Power - Ahh yes, I forgot I reviewed the HiFi Power before but if you want to experience the worst "planar sheen" in a planar driver IEM. You might want to torture your ears with the MUSE Hifi Power. Too harsh? It's mutual then. Joke, while the MUSE Hifi Power is decent in term of details and some technicalities, I find the MUSE Hifi Power to be very aggressive and spicy in the treble region. It also has the tendency to be sibilant and shouty in which the PR2 is absent with those nuances. Besides, the MUSE Hifi Power is too bulky, top it off with the uncomfortable sound.

2. TANGZU Zetian Wu - When comparing the PR2 and the Zetian Wu, both IEMs exhibit a departure from the typical "planar sheen." However, the Zetian Wu leans towards a more euphonic sound signature, offering a weightier lower region compared to the PR2. On the other hand, the PR2 excels in terms of soundstage, providing a wider and more spacious presentation compared to the Zetian Wu. While the Zetian Wu boasts a thicker and more lush tonality, the PR2 delivers a more open and detailed sound reproduction.

3. LETSHUOER S12 - Similarly, I can provide a comparison between the Zetian Wu, PR2, and the S12. The S12 stands out for its superior warmth and lushness, surpassing both the Zetian Wu and the PR2 in this regard. On the other hand, the PR2 offers more aggressive treble and decent imaging capabilities. However, when it comes to the engaging quality of the lower registers, the S12 outshines both the Zetian Wu and the PR2. It delivers a captivating and immersive experience in the lower frequencies. Additionally, the PR2 reveals more sparkle in the treble region, adding a sense of clarity and detail compared to the S12.



Pros:

• Improved sound from KZ
• Mild V-shaped signature
• Clean, decent mids
• Forgivable and inoffensive treble
• Decent technicalities for the price
• Cheapest planar driver so far
• Robust build

Cons:

• The bass doesn't have that much dynamics
• The QDC connection will always be a con for me
• Barebone packaging for a "premium" offering from KZ
• Not the most technical planars around
• As planars should, it requires more driving power to unleash its potential

In conclusion, the PR2 truly shines as one of the top budget planar IEMs, making it an excellent choice for those with budget constraints. It represents KZ's latest and improved offering, presenting a fresh take on their well-known dynamic-driver V-shaped sound signature. With the PR2, you not only get the familiar KZ quality but also a more refined and matured package that showcases the brand's continuous growth and development.

HIDIZS has recently released their latest dongle, which features a dual set of Sabre ESS chips, MQA support, digital filters, and a dual headphone output. The dongle also includes switching LED lights for aesthetic purposes. The device is priced at $99 and has a premium lightweight build.

DISCLAIMER:​

• I have no affiliation with Hidizs and have not received any monetary compensation during or after writing this review. Zoie Hello provided this unit to me in exchange for an honest and unbiased review.
• As a non-professional reviewer, I aim to use simple terms that can be understood by both beginners and experts in the hobby.
• Please keep in mind that the opinions expressed in this review are subjective and based on my personal experience with the unit. I encourage you to try the product yourself to form your own opinion.

PACKAGING​

The XO comes in a visually stunning box with a durable plastic case. Inside the box, you'll find a USB Type-C cable, a Type-C to Type A adapter, some manuals, and the XO dongle itself. The inclusion of the Type-C to Type A adapter makes it convenient to use with devices that do not have a Type-C port. The packaging and contents reflect the overall quality of the product and the attention to detail that went into its design.

BUILD QUALITY​

The HIDIZS dongle boasts an aluminum chassis with grills on both sides, through which the LED lights shine, creating a visually stunning effect. The slim and compact design makes it easy to carry around, as it can fit in your pocket without any issue. The durable and lightweight aluminum construction ensures that it can withstand everyday use while retaining its premium look and feel.

FUNCTIONALITY​

The XO does not offer any dedicated playback options, as the buttons on the dongle are reserved for other purposes. The "X" button controls the LED lights, allowing you to change their color and pattern. The "O" button, on the other hand, lets you switch between digital filters, giving you the ability to tailor the sound to your preferences. The lack of dedicated playback options means that you will need to rely on the hardware settings of the host device for playback and volume control.



The LED outer ring of the circular button on the XO dongle serves as a sampling rate indicator and filter mode switch. The indicator uses a color-coded scheme to represent different sampling rates, as follows:

• Green: PCM 44.1-96KHz
• Blue: PCM 192KHz
• Red: PCM 384KHz
• Yellow: DSD64-DSD256
• Orange: MQA unfolding

This color-coded scheme makes it easy to identify the current sampling rate and filter mode at a glance, adding convenience to the user experience. The LED indicator is a useful feature for people who want to monitor their playback settings and ensure they are optimized for their specific headphones and listening preferences.

Regarding the digital filter switch on the XO dongle:

• The red filter adjusts the frequency response by reducing high frequencies by 30-40% while boosting the lower intermediate frequencies. This results in a more well-rounded frequency response overall.
• The blue filter, on the other hand, decreases high frequencies by 20-30% while allowing the lower intermediate frequencies to stand out more. This leads to a more emphasized midrange.

The ability to switch between digital filters allows users to tailor the sound signature of the XO to their specific preferences and headphone sets. The red filter is a good choice for those who want a more balanced and neutral sound, while the blue filter is better suited for those who prefer a more emphasized midrange. Ultimately, the choice between the two filters comes down to personal preference and the specific characteristics of the headphone set being used. The digital filter does not drastically change anything to the sound so it does not prove that much purpose to me.

SOUND QUALITY​

The XO's sound signature is clean and analytical, providing a great level of detail. The XO's sound signature is not recommended for brighter headphone sets, as it may make the treble hotter than it should be, leading to a harsh listening experience. Despite these limitations, the XO excels in providing great detail, making it an excellent choice for those who prioritize clarity over warmth. The level of detail it provides can bring out nuances in the music that would otherwise go unnoticed. Overall, the XO is a great choice for audiophiles who prefer a clear and analytical sound signature and who are willing to sacrifice some warmth for increased detail.

CONCLUSION​

Pros:

• Provides an almost neutral sound
• DSD Support up to DSD256
• MQA Support
• Decent power output
• It has a 3.5mm unbalanced and 2.5mm balanced ports
• Very portable and lightweight
• Support to Type-C and Type-A all covered by its default inclusions

Cons:

• No playback buttons
• The colorful RGB aesthetics may not be everyone's cup of tea

The HIDIZS XO is a highly recommended device for anyone looking for an affordable on-the-go solution to enhance their mobile audio experience. The XO offers an excellent combination of high-quality audio output and portability, making it a great option for audiophiles who are always on the move.

One of the most notable features of the HIDIZS XO is its ability to deliver a crisp and clean sound that is far superior to the standard audio output found on most smartphones. This is especially valuable for users with devices that lack a dedicated DAC, as the XO is designed to provide a noticeable improvement in audio quality.

Moreover, the HIDIZS XO is incredibly easy to use and can be quickly connected to any smartphone or laptop with a USB-C port. This makes it an ideal choice for anyone who values convenience and wants to upgrade their audio setup without any hassle.

Furthermore, the HIDIZS XO is constructed using high-quality materials that ensure durability and longevity. Its sleek and compact design means that it can be easily carried around without adding any bulk to your pockets or bags. It is also worth noting that the dongle has a built-in amplifier that further enhances the audio output, making it a great choice for music lovers who want to get the most out of their headphones or earbuds.

In conclusion, the HIDIZS XO is a highly recommended dongle for anyone looking for an affordable, portable, and high-quality audio solution.

The Hidizs MS5 Dark Angel is an unusual name for an IEM, and it resembles a bicycle helmet more than an angel but it is very Chi-fi in terms of their naming convention. The MS5 is Hidizs' latest flagship IEM and I am about to get my hands on another amazing IEM. The Hidizs MS5 Dark Angel is currently on its pre-opening sale until May 5, 2023 so grab the chance to purchase this magnificent in-ear monitor while the promo is up.

DISCLAIMER:​

• I have no affiliation with Hidizs and have not received any monetary compensation during or after writing this review. Zoie Hello provided this unit to me in exchange for an honest and unbiased review.
• As a non-professional reviewer, I aim to use simple terms that can be understood by both beginners and experts in the hobby.
• Please keep in mind that the opinions expressed in this review are subjective and based on my personal experience with the unit. I encourage you to try the product yourself to form your own opinion.

PACKAGING:​

​

The packaging of this in-ear monitor is the boldest and most impressive I've seen in its price range. It doesn't have any corny random excerpts or flashy anime covers, which I find less appealing and cheap-looking. Instead, the packaging is sleek and sophisticated, featuring a clear product preview, the brand responsible for making it, and a brief description of its features.​

Overall, the packaging exudes a premium quality that matches the product's high-end performance. It's refreshing to see a product that doesn't rely on gimmicks to grab attention but lets its quality speak for itself.

What's inside the box:​

• Hidizs MS5 Dark Angel
• 9 pairs of eartips
• Cable
• 2 pairs of extra tuning filters (bass and treble)
• Earphone case
• Manuals and other paperworks

BUILD QUALITY:​

The MS5 Dark Angel boasts a sleek and durable design, featuring a lightweight aluminum shell. The black resin faceplate provides a glossy finish that perfectly complements the matte aluminum body of the in-ear monitor, creating an elegant and modern look.

SOUND:​

The MS5 Dark Angel sound profile can be customized by swapping out the tuning filters. I found that the differences between the filters were not significant enough to justify switching from the balanced filters. The sound profile of the MS5 has a U-shaped curve, with a strong bass and emphasized treble. The MS5 Dark Angel makes an impressive job at creating a fun and energetic IEM.​

BASS:
The Hidizs MS5's bass is one of its most impressive features, delivering a powerful and energetic sound that is sure to please bass enthusiasts. The sub-bass has exceptional depth and rumble, which provides a satisfying listening experience without feeling overly heavy or thick. While the MS5's bass is not quite as prominent as some other bass-heavy earphones, it still manages to deliver an impactful and immersive bass response that can be appreciated by both casual listeners and audiophiles alike. The bass is also well-controlled, which means that it doesn't bleed into the mid-range or overpower the other frequencies.

MIDS:
The Hidizs MS5's mid-range is laid-back, providing a relaxed and natural sound signature. The vocals, in particular, stand out and deliver exceptional clarity and precision. The male vocals have a deep and rich quality that brings out the lower register of the voice, while the female vocals have a mature and passionate tonality that is both emotive and expressive. When it comes to the instruments, the Hidizs MS5 does a solid job without necessarily standing out. The instruments are well-defined and articulate, but they do not have the same level of emphasis as the vocals or the bass. However, this is not necessarily a drawback as it allows for a more balanced sound signature. While the instrument reproduction might not be the most outstanding feature of the MS5, it still provides an enjoyable and engaging listening experience that is sure to satisfy most music lovers. Overall, the MS5's mid-range strikes a perfect balance between a laid-back sound and detailed vocal performance, making them an excellent choice for any audiophile.

TREBLE:
The treble of the MS5 is noticeably emphasized, which adds brilliance, clarity, and air to the sound signature. However, I did encounter a few issues worth mentioning. The treble is not always consistent and occasionally has spikes that can sound splashy. This made my experience to listening to the MS5 for extended periods of time uncomfortable and lead to listening fatigue after an hour or two. Personally, this may be a bit hot for my ears. Despite these shortcomings, the MS5's treble extension is still impressive for its price and may be enjoyable for those who prefer a more pronounced treble.

TECHNICALITIES:
The soundstage of the Hidizs MS5 has a moderate width, which may not be as expansive as some other high-end earphones. Nevertheless, the soundstage remains engaging and enjoyable to listen to, with good separation and accurate imaging. The MS5's ability to deliver a clear and accurate instrument separation is commendable, making it easy to distinguish between different instruments and their placement in the soundstage. The overall instrument reproduction is well-suited for various music genres, making the MS5 a versatile choice for any listener. The MS5's sound resolution is also impressive, as it maintains clarity and detail without sounding blurry or muddled. Even though the MS5 is not a clinical in-ear monitor, it still manages to capture both macro and micro-details, adding a subtle but noticeable level of depth and texture to the sound.




In conclusion, the Hidizs MS5 Dark Angel is a fun and energetic IEM that delivers a powerful and impactful bass response, relaxed and natural mid-range, and an emphasized treble extension that may be preferred by some but might cause fatigue for extended listening sessions. The MS5's soundstage, instrument separation, and sound resolution are impressive for its price point and provide an enjoyable listening experience. While the differences between the MS5's tuning filters are not significant enough to warrant switching, the customizable sound profile is a unique feature. Overall, the Hidizs MS5 Dark Angel is a solid choice for anyone looking for an engaging and versatile pair of earphones.

As an upgrade from the Galileo we reviewed before, the Cadenza 12 boasts an impressive 12 multi-hybrid driver configuration, incorporating premium drivers from Sonion and Knowles Balanced Armature. We would like to express our sincere appreciation to HiFiGo for granting us the opportunity to review this flagship model, and to Neil Nino Clark for facilitating this review tour. Without further ado, let's delve into our comprehensive review of the LETSHUOER Cadenza 12.

DISCLAIMER:​

• I have no affiliation with LETSHUOER and have not received any monetary compensation for this review. The unit was provided by HiFiGo in exchange for an honest and unbiased review.
• I am not a professional reviewer and will use simple terms for easy understanding by beginners and experts alike in the hobby.
• Please take the words in this review with a grain of salt, as trying out the unit yourself is still the best way to gauge the experience.

PACKAGING:​

The packaging of the LETSHUOER Cadenza 12 is nothing short of exquisite. It comes in a meticulously designed three-layered box, starting with a cardboard box featuring LETSHUOER's branding, followed by a silver carton, and finally, a sleek black jewelry box containing the in-ear monitors and their accessories. The packaging is a true testament to LETSHUOER's commitment to luxury and attention to detail, leaving a lasting impression from the moment it's unboxed.

The cardboard box is well-crafted and prominently displays LETSHUOER's branding, adding to the overall aesthetic appeal. The silver carton adds an additional layer of sophistication, further elevating the unboxing experience. The jewel of the packaging, however, is the sleek black jewelry box that houses the in-ear monitors and accessories. It's not only visually stunning but also functional, providing secure and organized storage for the monitors and ensuring they arrive in pristine condition.

The premium packaging of the Cadenza 12 adds to the overall sense of value and sets the tone for the quality and craftsmanship of the in-ear monitors. It's a thoughtful touch that reflects LETSHUOER's commitment to delivering a premium listening experience from the moment the package is opened.

BUILD QUALITY:​

The LETSHUOER Cadenza 12 features a robust build with a slightly bulky and relatively heavy shell. Despite its weight, it remains comfortable to wear for extended periods of time without causing discomfort. However, it's worth noting that the shell is not scratch-proof, and some light scratches may occur over time, although this is a minor concern compared to its sound performance.

The modular cables included with the Cadenza 12 are of good quality, allowing for termination swapping. However, it's worth mentioning that the process may not be as user-friendly and may require assistance from peers. On the bright side, the included case is a notable improvement from the Galileo, featuring a magnetic closure that securely snaps into place, ensuring safe storage and transport of the monitors.

The package also comes with plentiful eartips, including hybrid eartips, which is a nice touch. However, it's worth noting that the "bass" eartips may not significantly affect the bass texture and weight as their name suggests. Nonetheless, the inclusion of a variety of eartips allows for customization and finding the best fit for individual preferences, further enhancing the overall comfort and performance of the Cadenza 12.

SOUND:​

Profile: The in-ear monitors boast a vibrant and engaging sound signature with a touch of warmth, while maintaining an overall neutral profile. This combination results in a lively and dynamic audio experience that brings music to life. The warm tonality adds richness and depth to the sound, without compromising the accuracy and clarity of the audio reproduction. The balanced profile ensures that different frequency ranges are well-represented, making these monitors suitable for a wide range of music genres, from rock to classical and everything in between. Whether you're a casual listener or an audiophile, these monitors are designed to captivate your ears and elevate your music listening experience.

Bass: The bass is well-rounded, with a subtle lift that adds warmth to the overall sound without overpowering the midrange. Unlike some bass-heavy in-ear monitors, the Cadenza 12 maintains clarity and definition in the midrange, preventing any muddiness or distortion. The midbass is a standout feature of the Cadenza 12, offering a punchy and tight performance that is sure to impress. While it may not produce the deepest sub-bass rumble, it makes up for it with its well-defined and dynamic midbass performance.

The Cadenza 12 bass delivers a well-balanced and refined audio experience. Its warm representation without excessive emphasis on low frequencies, along with its punchy and well-defined midbass, makes it an excellent choice for audio enthusiasts who appreciate quality and precision in their audio playback.

Midrange: The midrange of the audio output is characterized by its clarity and precision, allowing for an accurate reproduction of vocals and instruments. Although there is a slight boost in the lower frequencies, the midrange maintains a natural tone without excessive lushness or euphonic coloration. Instruments are rendered with lifelike detail, showcasing fast decay and realistic timbre. The upper midrange is well-defined and energetic, without any harshness or recessed characteristics, adding to the overall dynamic and vibrant sound signature.

Treble: The treble is well-extended and detailed, though it can be overly bright and cause fatigue with certain eartips due to its high frequency emphasis. Choosing the appropriate eartips can help address this issue, and with a proper fit, the treble is clear and shimmering without any harshness. Instruments such as cymbals and hi-hats are accurately reproduced with good resonance and crispness.

Soundstage and Imaging: The Cadenza 12 exceeds expectations in its technical performance, boasting an expansive soundstage with excellent height and spaciousness. Imaging is precise, with instruments accurately placed and microdetails rendered with clarity and precision. The separation between instruments is outstanding, even in busy tracks where budget earphones often struggle with muddiness. Tracks like "Another One Bites The Dust" by Queen and "The National Anthem" by Radiohead are handled effortlessly. Tonally, the Cadenza 12 offers a natural and realistic presentation without sounding overly clinical or unresolving.

COMPARISONS:​

Noble Audio Viking Ragnar

Noble Audio Viking Ragnar ($4000): Priced at twice the cost of the Cadenza 12, the Noble Audio Viking Ragnar offers a different listening experience. The Ragnar is more analytical, with a focused and tamed treble, and boasts superior resolution and detail retrieval. On the other hand, the Cadenza 12 provides a more affordable flagship experience with a more fun-sounding tonality, making it a compelling choice for those who prefer a warmer and more natural sound.

KINERA URD


Kinera Urd ($650): The flagship of Kinera, the Urd, is priced lower than the Cadenza 12 and leans towards a safer tuning with less emphasis on bass and laid-back treble. However, the mids are more euphonic and engaging, with a bias towards female vocals and plucked string instruments, making it a good option for those who prioritize these qualities in their listening experience.

SIMPHONIO VR1

Simphonio VR1 ($2299): Priced similarly to the Cadenza 12, the VR1 offers a warm-balanced signature with a darker overall tonality compared to the Cadenza 12. The major difference is that the Cadenza 12 utilizes twelve drivers, while the VR1 relies on a single dynamic driver. The Cadenza 12 has the advantage in handling different frequencies and maintaining consistency, resulting in a more natural sound compared to the darker tonality of the VR1.

Pros:

• Excellent warm-neutral sound signature
• Punchy and well-defined bass without bleeding into other frequencies
• Wide soundstage, precise imaging, and superior separation
• Microdetails are clearly defined
• Keen treble
• Outstanding packaging
• Sturdy titanium alloy shells that are bulky yet lightweight

Cons:

• Shells are not smudge and scratch-proof despite their pros
• Less clinical/technical compared to some other TOTL options
• High price point, recommended to try before buying

FINAL RATING​

CONCLUSION:
In addition to its impressive performance, the Cadenza 12 also boasts a sleek and stylish design, with a durable build that can withstand, if not most, the rigors of daily use. The attention to detail in the craftsmanship is evident, from the metal housings to the high-quality cables and connectors. The fit and comfort of the Cadenza 12 are also noteworthy, with multiple ear tip options and an ergonomic design that ensures a secure and comfortable fit for long listening sessions.

One of the standout features of the Cadenza 12 is its exceptional soundstage, providing a wide and immersive listening experience. The instrument separation is superb, allowing for each element of the music to be distinct and well-defined. The bass response is powerful and controlled, while the midrange is detailed and transparent, and the treble is crisp and extended without being overly harsh. The overall tonality of the Cadenza 12 is balanced and natural, making it suitable for a wide range of music genres.

It's important to note that the Cadenza 12 is not for everyone, as its premium price tag may be prohibitive for some potential buyers. However, for those who are serious about their music and demand the best in terms of performance and build quality, the Cadenza 12 is a top contender. It's advisable to audition them before making a purchase decision, as personal preferences may vary. Despite its price, the Cadenza 12 delivers a listening experience that is truly exceptional and worth considering for audiophiles and music enthusiasts alike.

Kinera Urd is one of the latest tri-brid IEMs from Kinera. It has 2 Sonion EST + 1 Kinera Custom BA + 8mm Dual Dynamic Drivers. I am excited to review this pair since I have high expectations for them and they did not seem to fail.

PACKAGING​

The unboxing experience is a wonderful one. I am not a fan of the multiple fonts used on the box, though. The whole package is encased in a hexagonal box with lots of text and random stuff. For $650, a lot of eartips are included, as is a collaboration with Final Audio with 5 pairs of Final eartips. However, the rest of the eartips feel too cheap for a $650 package.

What's inside the box?​

BUILD QUALITY​

No arguments here, the build quality is outstanding. The Urd has a cool and refreshing design that reflects the wonders of the oceans. The cables look sturdy and can take a beating. The modular cables don't feel loose, I can't assure that in the long run, but the plugs look very seamless. As for the eartips, do we even need to doubt the Final E eartips? We all know these have been our go-to budget eartips for their comfort and durability. I can't say for the rest of the eartips. For $650 the rest of the eartips feels very cheap. Could have expected at least an Azla Sednafit replacing the clear KBEAR-like eartips, and a Comply memory foam tips, am I asking for too much? I think I am.

SOUND:​

BASS: The bass has good impact and quantity. The attack and decay are very quick on the uptake but lack sub-bass depth and rumble. The midbass is more defined, with a robust body and subtle punches. The overall bass is very balanced, with no exaggeration or dominance on the lower frequencies. Die-hard bassheads will have to take a pass on these pairs. This would still be a go to pair if you are not that much of a basshead.


MIDS: The mids have excellent resolution, harmony, and details. The synergy between the vocals and instruments offers an almost lifelike and engaging experience. Instruments are exceptional, especially stringed instruments. Seriously, Here Comes The Sun sounded way different than I remember, and the acoustic guitar is very emphasized. The bass guitar is an exception; I can barely feel the bass playing on the same track. Personally, I prefer the female vocals in this pair, as they sound richer in comparison to the male vocals. The Urd smoothly transitions from the upper mids with no harshness and obvious peaks.


TREBLE: Treble is surprisingly inoffensive and laid-back. The big drawback of the treble is that it may be too safe for some, it is lacking in treble energy, so you'll definitely miss all the sheen and sparkle. It doesn't seem to share the same level of coherency between the lower and middle frequencies.


TECHNICALITIES: While IEMs, especially closed back in-ear monitors, don't offer the same openness and space compared to open-back sets, the soundstage of the Urd is wide and a lot more decent than most IEMs in the market. Sounds coming from this pair don't feel congested and float in a specific area. This gives a good sense of space between the vocals and instruments. Details and microdetails are decent despite its safe tuning, and you may hear sounds you've never heard before in a good recording. The Urd can keep you engaged for hours with its almost lifelike tonality. It still suffers from a lack of dynamics and has an overall laid-back presentation. The overall technicalities are not the best, but they are not the worst either.




The Kinera Urd is one of the most excellent and stunning in-ear monitors I've seen in the Chi-Fi market. Most of the things I could say about the Kinera Urd are positive, with fewer negatives. However, with the price of $650, this purchase is no walk in the park for someone like me and then wind up disliking it.

Pros:

• Great soundstage
• Excellent tonality
• Looks bulky, but it's comfortable and surprisingly light
• Lifelike vocals and outstanding emphasis on some stringed instruments
• Has a favorable intimacy with female vocals
• Premium build and a wonderful unboxing experience
• Modular cables

Cons:

• Lower frequencies lack sufficient weight
• Lacking treble energy and clarity
• Expensive

There have been a lot of collaborations going on here and there, but somehow not every collaboration worked out the way we wanted. There are the good ones and the truly terrifying ones. This time, Gizaudio is taking part in a collaboration with LETSHUOER. We have the LETSHUOER Galileo, which has a design that will transport you to the vastness of space.

DISCLAIMER:​

This is a tour unit provided by HiFiGo; I was not compensated prior to, during, or after the review. This review was loaned to me to provide an honest opinion about the unit.

PACKAGING​

The packaging has a simple yet aesthetic feel. It has numerous inclusions, and the included case feels premium; however, the case is difficult to open, and forcing it open may cause it to break. Using a flathead screwdriver or something flat and sturdy may be the key to prying these open, but save yourself the trouble because there's a trick to it. Simply apply light pressure to the case's surface and pry the lock open with your fingers.

Now what's in the box?

• Galileo IEMs
• An overly protective case
• A cable
• Cleaning brush
• 6 pairs of eartips (3 pairs narrow bore and 3 pairs wide bore)
• And some paperwork, and love letters you would probably need (or not).

BUILD​

The Galileo drivers are housed in an attractive, lightweight resin shell. The nozzle mesh looks cheap, but I hope it's durable in the long run. The IEM itself is very comfortable to wear, fits like a glove, and doesn't feel bulky. The cables feel premium and don't tangle. I find the eartips to be personally uncomfortable, especially the white ones. The black eartips are softer but still feel uncomfortable to wear.

SOUND​

With the market overflowing with U-shaped IEMs that really tire me out on reviewing any more IEMs, the Galileo made a difference, and the moment I plugged in these IEMs, I was surprised at how neutral they were compared to the other IEMs on the market. It has its own downsides, though, that may turn off casual listeners, which I will explain in detail below.



Lows: This would probably be the biggest turn-off for many as the bass lacks engagement and energy that a casual enthusiast might crave. It still has that presence, but it might sound dull and flat to bassheads. Subbass is almost absent and can hardly be felt. Midbass is lacking in weight and quality, which makes it sloppy and awkward in some tracks. Personally, it's still tolerable, but I think the bass is played too safe here to be adored by most listeners. However, that lack of bass adds that neutral, uncolored feel.



Mids: The lack of bass paves the way for the mids to truly shine. The midrange is clean, natural, and rich. It could be richer if more weight is added to the lows. Nevertheless, it's only my preference, but with its current tuning, I'd say the midrange is well emphasized and vocals really shine. The upper midrange is safely tuned but doesn't sound endearing. Some people, like me, might demand more meatiness in the mids to add more intimacy to female vocals and more soul and thickness to male vocals. Then again, playing it safe wouldn't be a bad idea.



Treble: The treble has a decent amount of air and clarity. It doesn't sound metallic or jarring to the ears, and it is free of sibilance. They really played it safe with the whole frequency while still having a fair amount of details.



Technicalities: The soundstage is decent but not phenomenal. It has enough width to separate the vocals from the instruments but doesn't have that three-dimensional depth. The imaging can break down vocals and instruments as accurately as possible.





Pros:

• An almost neutral sound signature
• Looks very nice
• Inoffensive sound
• Lightweight and fits well in the ears

Cons:

• May sound very boring to some
• Average technicalities
• Lacks bass weight and texture
• An overly protective case that feels like a Pandora's Box

While the Galileo looks very aesthetic, it may not satisfy the majority of listeners and bassheads in its current tuning. It may leave others with a boring, lifeless pair of IEMs and may not be the most competitive against the others in the market, but it's a great niche choice for those who wanted a safe and neutral tuning. These are for the absolute enthusiasts of neutral sound or for those who wanted to take a breath of fresh air from the condensed selection of U-shaped IEMs in the market right now. If you are one of Galileo's target consumers, I would highly recommend this pair, and Gizaudio did a good job with this collaboration.
