SIVGA ANSER

The Sivga Anser immediately grabs your attention with its craftsmanship—it’s like the headphones equivalent of fine furniture. As my first pair of wood headphones and my first experience with Sivga brand, let’s just say the bar has been set. The solid wood housing, polished to a glossy perfection, oozes warmth and class. It stands out in a world of plastic and metal like a handcrafted rocking chair in a sea of IKEA furniture or those plastic monoblock chairs i see almost everwhere. Each cup feels like it belongs in an art gallery, and the CNC-machined sound chamber doesn’t just look the part—it plays it too, delivering precise acoustics. The metal bracket adds a dash of modernity, offering durability and flexibility without turning the Anser into a neck workout device.

At 342 grams, the Anser feels just right—weighty enough to scream “premium” but light enough to keep your head happy during hours of listening. The suspension headband and plush earpads are like the coziest pillows for your ears, making marathon listening sessions more enjoyable. Sure, the open-back design won’t drown out my neighbor’s dog barking or those pesky motorcycles with loud ass exhaust pipes roaring sound as it passes by outside my house.. but who cares when it delivers that open, airy soundstage that makes you feel like you’re in the middle of a live performance? A fair trade-off for pure audio bliss.

Versatile Impedance and Sensitivity

With an impedance of 38 ohms and a sensitivity of 105dB, the Anser strikes a balance between accessibility and performance. It’s easy to drive, making it compatible with a variety of devices, from smartphones and laptop to portable audio players. However, if you really want to experience the Anser at its best, pairing it with a dedicated DAC/amp is highly recommended. Doing so unleashes its full potential, improving dynamics, bass control, and overall tonal balance.

The Anser is like an open invitation to fall in love with your favorite tracks all over again like when i am indulging in casual listening or diving into a session of critical analysis for my comparisons and reviews, its thoughtful design and premium components come together to create a refined, immersive experience. To truly unlock its potential, i pair it with a quality and powerful source—it thrives on clean, capable amplification, letting you savor every bit of its engineering finesse.

I’m a firm believer in the power of volume headroom, whether it’s for IEMs or headphones. The more headroom you have, the less chance of distortion or clipping, and the result? A more dynamic, impactful sound that lets the music breathe effortlessly.

Unboxing Experience

The unboxing experience of the Sivga Anser is modest but satisfying. It strikes a balance—neither too extravagant nor overly basic. The headphones arrive in a well-organized cardboard box, accompanied by:

A detachable braided fabric cable (3.5mm termination) – long, flexible, and of good quality, an aftermarket upgrade could enhance performance for discerning users.

6.35mm adapter – standard for connecting to amps or professional audio equipment.

Carrying bag – soft and lightweight, great for home storage but inadequate for robust travel protection.
While I would have preferred a hard-shell case for better protection, the overall presentation is practical and user-friendly.

Technical Highlights

50mm Titanium-Plated Driver

At the heart of the Sivga Anser lies a 50mm titanium-coated driver. This advanced diaphragm design enhances rigidity, reducing distortion for crisp, accurate sound reproduction. The result? A sound signature that maintains clarity even during intricate, layered tracks.

24.5mm NdFeB Magnet Circuit

The Anser employs a high-performance neodymium-iron-boron magnet, ensuring a dynamic and responsive driver.

Open-Back Design

The open-back configuration is a hallmark of the Anser, allowing for unrestricted airflow that minimizes resonance and enhances natural frequency response. This results in an expansive, airy soundstage that can be immersive and true to life.

Versatile Impedance and Sensitivity

With an impedance of 38 ohms and a sensitivity of 105dB, the Anser is easy to drive, However, pairing it with a dedicated DAC/amp elevates its performance, unlocking improved dynamics, deeper bass, and richer tonal balance.

Key Design Highlights:

Ultra-lightweight build enhances long-term wearability.

Soft velvet earpads (25mm thick) provide a plush, breathable fit.

Rotating earcups improve flexibility and comfort, ideal for various head shapes.

Minimal clamping force ensures fatigue-free listening for hours.

In short, the Anser is one of the most comfortable headphones I’ve worn in this price range. Even after hours of use, it remains gentle on the head and ears.

Sound Performance

The Sivga Anser delivers a well-rounded and engaging and balance sound signature. It walks the line between analytical and musical, offering enough detail for critical listening while remaining enjoyable for casual sessions.

Bass

The bass response of the Anser is delivers a tight controlled performance that feels both precise and deliberate. Its natural decay works harmoniously with the open-back design, providing an authentic and spacious listening experience. Subbass extension is present, offering a subtle rumble that adds a sense of depth to tracks. However, it leans on the conservative side, which may leave some bass enthusiasts craving a bit more weight and impact. That said, this restraint is typical of open-back headphones, where the focus is more on balance and openness rather than overpowering low frequencies.

The midbass, on the other hand, provides a satisfying punch without overshadowing other elements of the sound. It adds richness and texture to genres like jazz, giving upright bass lines a tactile presence, and injects a lively energy into to myt 90s alternative rock tracks, where kick drums and bass guitars come through with a natural yet impactful authority. The overall bass tuning feels intentional—never boomy or bloated its to be expected since this is an open back cans, midbass is well-integrated into the overall signature, enhancing the listening experience with clarity and depth without even adding warmth to the lower midrange.

Midrange

The Anser places a strong emphasis on the midrange, making it an excellent choice for those who prioritize vocals and instruments in their listening experience. The mids are lush, full-bodied, and exceptionally clear, offering a sense of richness and a little warmth that feels both natural and engaging. Vocals, whether male or female, are presented with striking intimacy, sounding vivid and emotionally resonant. They are rendered with precise tonality, sitting slightly forward in the mix, which makes them feel closer to the listener. This characteristic is particularly enjoyable for vocal-heavy tracks, where every variances in the singer's voice shines through.

Acoustic instruments like guitars and pianos are equally well-represented, boasting a lifelike presence with a warm and organic timbre. The Anser captures the subtle textures of strings and the resonance of piano notes with impressive authenticity. The upper midrange is elevated just enough to inject energy and excitement into the sound without veering into harshness. Crucially, this boost does not bleed into the lower treble, maintaining a clean and controlled transition that ensures long-term listening comfort.

Treble

The treble tuning on the Anser strikes an ideal balance between detail and smoothness, making it accessible yet refined. High frequencies are presented with a sense of airiness and extension, adding a touch of sparkle that enhances the overall sound signature. Despite its clarity and detail retrieval, the treble never becomes harsh or fatiguing, even during extended listening sessions.

The titanium-coated driver plays a key role here, delivering crisp and precise transients. This ensures that cymbals, strings, and upper harmonics are reproduced with clarity and definition, maintaining a lively character without ever crossing into piercing or sibilant territory. A gentle roll-off in the upper treble contributes to the Anser's slightly "analog" tonal character, creating a smooth and enjoyable listening experience that is as forgiving as it is engaging. This approach makes the treble ideal for both casual listening and critical evaluation, striking a sweet spot for me specially when i paire it with my Fiio K11 R2R dac with the Fosi MC331 hybrid tube amp.

Soundstage & Imaging

Thanks to its open-back design, the Anser delivers a soundstage that feels natural and spacious without sounding exaggerated. It provides enough width and depth to create a convincing sense of space, allowing instruments and vocals to occupy their own defined positions in the mix. The soundstage avoids being overly expansive, which helps maintain a sense of focus and cohesion.

Imaging is a standout feature, with excellent precision and separation between layers of sound. Instruments are easy to locate within the sound field, making the Anser particularly enjoyable for complex arrangements like orchestral pieces or layered studio recordings i also enjoy it with some solo vocalist, a live jazz performance, or a dense electronic mix, the Anser handles the task with finesse and an immersive auditory experience that never feels cluttered.

Resolution & Dynamics

Resolution: Good for the price; it reveals micro-details in simpler tracks but can struggle with very dense or complex arrangements.

Dynamics: Excellent for capturing shifts between soft and loud sounds, adding life and energy to recordings.

Use Case Versatility:

The Sivga Anser is marketed as a versatile headphone, and it largely lives up to this claim:

Music: Its musical tuning fits well with genres like pop, rock, jazz, and light electronic.

Movies: The controlled bass and spacious soundstage enhance cinematic audio.

Gaming: Clear imaging and balanced tuning provide an immersive and competitive edge.

Room for Improvement:

While the Sivga Anser is a commendable all-rounder, a few areas could see improvement:

Carrying case: A hard case would add much-needed protection for on-the-go users.

Treble sparkle: Slightly more treble extension could improve detail and air.

Sub-bass impact: Additional depth would appeal to bass enthusiasts but this is understandable since its an open back design.

Final Thoughts

The Sivga Anser is like a well-tuned classic car—it’s not flashy or trying to be everything at once, but what it does, it does exceptionally well. Its tight bass, lush mids, and smooth treble come together in a cohesive package that prioritizes clarity and balance over gimmicks. While bass lovers might wish for a bit more subbass rumble, the Anser makes up for it with its midrange magic and refined highs. Add to that an expansive soundstage and precise imaging, and you’ve got a headphone that’s equally at home in a critical listening session or a casual late-night jam.

It’s not perfect, but it doesn’t need to be. The Anser feels confident in its identity, delivering a sound that’s detailed, engaging, and easy to live with. If you’re someone who values mids and a natural, balanced sound, this one’s definitely worth a listen.

INTRO

Welcome to the written review of Critica Actual. Today it's time to see an over ear. It's about time. The Sivga Anser.
It's been a while since we've seen a Sivga headphone. A brand that I like a lot because I think it meets the requirements of an audience that seeks a particular tuning. It shouldn't all be purist and technical or correct profiles. Also, at Sivga, it's usual for the designs of their products to be very elegant and comfortable. I don't mean to say that the Sivga Anser is like that...just that until now Sivga's products have deserved attention and with good reasons. This Anser is the latest model of a brand that already has an important list of over ear headphones, open and closed. Sv021, Oriole, Phoenix, Luan, Sv023...and now the Anser.

UNBOXING SECTION

The unboxing experience is normal. It doesn't feel like a very expensive product. It doesn't feel like a cheap product either. I think it corresponds to the selling price.
We have a cardboard box where the product comes. It is presented in an optimal way. We have the headset, which I will now talk about the aspects, comfort and other little things, along with a very nice and long detachable braided fabric cable with a 3.5mm connection. It is not the Sv023 cable but I think it is better than, for example, the Sv021 cable, which I thought was a pretty good cable.

Apart from this we have the typical 6.35mm adapter and a Sivga carrying bag. If I remember correctly, it is the one that usually comes with other products. I always say and will say the same thing. These bags are not useful for transporting the headset itself because they do not protect it. They are used to store it at home and not get dusty. A carrying case would have been great, but I'm happy with it because I like what I get.
The headset feels and looks elegant. It's true, once you put it in your hand you notice that it's a product of a lower value than, for example, the Sv023, but it still gives you a feeling of good construction and durability. Maybe that feeling of a "cheaper" product is due to its excellent weight, which is ultra-light.
Returning to the headset we have metal parts, extendable and adjustable, and a wooden design made carefully and by hand, according to the brand. Honestly, it feels good. One of the strong points of the headset is its comfort. Unlike my Hifiman Ananda Nano, I can wear this one for hours. It combines 3 things. A very low weight, a soft headband, without much camping force and padded and, finally, 25mm thick soft velvet ear cushions. And yes, it won't be like the Phoenix here. Your ears will fit completely since it has a 60mm space inside.
As if that were not enough, the cups rotate like the top models of the brands, something that is appreciated in sivga products.

SOUND

Before getting into purely sonic aspects I want to highlight a series of features. 38 ohms of impedance and 105 of sensitivity. For some reason, although I think they are not as demanding as the Sv023, they do need power. A DAC dongle will not be enough unless you give it about 150-200mw. If you want it to live up to its potential, give it power.
Now getting into sonic aspects we have a dynamic driver Sivga headphone.
How does it sound? Well, like a dynamic driver Sivga headphone. A musical profile that fits very well with genres such as dance, certain types of pop and also for watching movies, for example. Don't expect a purist or neutral profile. Sivga tends to color its products a bit. Especially the lower priced ones. The Sivga Anser comes with a powerful bass, although for me it is somewhat far from what bassheads may want, a somewhat forward and present midrange and smooth highs with a feeling of a certain level of overall refinement. The sound is perceived as clean, natural and with enough body, although I would have liked a little more weight in the notes.

SOUND SECTION - BASS

Despite what the brand says, the SIVGA Anser's bass is characterized by a more controlled than explosive approach. This does not mean that it does not have bass or that it is light. No. I am simply saying that perhaps for some genres certain people may want more. Unlike headphones with an exaggerated bass profile, the SIVGA Anser focuses on a more precise but present representation.
The SIVGA Anser's bass has adequate extension, but does not become particularly deep or boomy in the sub-bass frequencies (the lowest frequencies, below 50 Hz). Although there is bass presence, it does not have the kind of impact that shakes the chest. However, the mid-bass (frequencies between 60 Hz and 200 Hz) is well controlled and present, providing a good sense of body and weight to the music without muddying the midrange. One of the SIVGA Anser's great strengths in this department is the control it offers in the low frequencies. The bass does not extend in an uncontrolled manner nor does it negatively affect the clarity of the midrange. In addition, the SIVGA Anser's bass is fast, meaning it responds well to transients and has a quick recovery.
So to sum up, the bass does not dominate the sound presentation but it has enough impact to be enjoyed in musical genres that require a certain forcefulness, such as rock or light electronic music. However, it will not be the best choice for listeners looking for a very bass-heavy listening experience or with a pronounced "thump" in the sub-bass, as mentioned above.

SOUND SECTION – MIDS

The midrange of the SIVGA Anser is possibly its most outstanding and appreciated feature for me. The presentation of the mids is rich, well detailed and balanced, with a tonality that tends towards warmth, which helps both vocals and lead instruments in this frequency region feel present and well defined. One of the most notable aspects of the midrange in these headphones is its naturalness. Vocals, both male and female, are represented with great precision and richness, without sounding either too close or too far away. This provides a sense of realism that is essential in genres such as jazz, acoustic music or classic rock, where vocals and acoustic instruments take center stage. In addition, the good articulation in the mids makes subtle details, such as the attack and resonance of string instruments, reproduced clearly.
Another important aspect is the clarity in the midrange. Instruments operating in this region (guitars, piano, vocals, etc.) are well separated, allowing for good spatial perception in the mix. There is no feeling of congestion, even in tracks with many layers of sound, reflecting good resolution and correct interpretation of details.
It is important to note that the SIVGA Anser achieves great cohesion between the midrange and the other frequencies (bass and treble). The midrange is not overshadowed by the bass or eclipsed by the treble, providing a feeling of overall balance in the sound.

SOUND SECTION – TREBLE

The treble of the SIVGA Anser expresses good clarity and definition, without becoming too shrill or sibilant, making them pleasant for long listening sessions. One of the most notable features of the treble in this model is its smoothness compared to other headphones from the brand such as the Sivga Luan. They are not especially bright or punchy, but offer enough detail to provide an accurate representation of higher frequency sounds, such as cymbals, bells, and other instruments with pronounced treble components.
The treble has a decent extension, meaning that louder sounds come through clearly, but without becoming so overly present that they can cause ear fatigue. This type of treble response helps make the SIVGA Anser a suitable headphone for people who enjoy a quiet listening experience without sacrificing comfort. However, the lack of brightness, which is noticeable in certain genres, may not satisfy those who prefer crisper or brighter treble, especially in music genres that benefit from a more airy and expansive presentation in the high frequencies, such as contemporary jazz, classical, or modern pop.
One of the virtues of the SIVGA Anser's treble is its neutrality and control. There is no excess boost in the higher frequencies, which prevents the headphones from sounding harsh or unbalanced.

SOUND SECTION – TECHNICALITIES

The SIVGA Anser for me is a semi-open design headphone, it offers a relatively large soundstage compared to closed headphones, including the SV021 or the Oriole. The Anser is able to create a decent sense of depth and dimension. The Anser creates a kind of bubble around your head that feels nice. It is deep (Z axis) and more or less wide (X axis). Not bad at all. I am being a bit unfair. I have to consider the price so for the price it is very good.
However, the soundstage is not as wide as fully open models from other brands or even compared to the Luan or the Sv023. In fact, the Sv021 has a very wide soundstage that is similar to this or slightly smaller. While semi-open headphones offer a good balance between isolation and spaciousness, if you are looking for a large-scale immersive soundstage you may want to look at something from AKG's K7 series at these prices.
The SIVGA Anser's imaging is another of its strong points. The SIVGA Anser offers precise localization of instruments and vocals, allowing the listener to easily identify where sounds are coming from within the mix.
In terms of resolution, the SIVGA Anser offers a very good ability to reproduce fine details in music. Although it is not at the level of the company's top-of-the-range headphones, the resolution is sufficient to pick up subtle textures in vocals, string instruments, or fast transients, such as cymbals and percussion details. In other words, it allows you to enjoy those small nuances that make a recording feel more vivid and realistic.
However, you might notice, like me, a slight lack of micro-details in very dense or complex tracks. Nevertheless, for its price range, the level of detail is more than adequate.
As I mentioned previously in the bass section, transients (rapid changes in sound) are well handled by the SIVGA Anser. The drivers have a good speed, allowing them to react quickly to changes in dynamics and rhythm. This is especially important for complex music, where many sounds occur simultaneously and require a quick response to avoid the music sounding blurry or imprecise.
Instrument separation is notable, but I wish it was better. Different musical elements have their own space within the soundstage, but it falls short of the experience of a magnetic planar.
Finally, as for dynamics, I liked it. The SIVGA Anser handles the differences between soft and loud sounds well. The ability to capture these dynamic fluctuations in music is important for immersive listening, as it allows recordings to sound lively and expressive – adjectives that Sivga often employs in its sonic profiles.

SUMMARY SECTION

The Sivga Anser is billed as a do-it-all headphone. Music, gaming, and movies. Perhaps the most versatile of the brand. It doesn't take too many risks so it may appeal to more people. It will be great for those looking for a nice profile that they can use without fatigue and that has a decent technical level. Excellent considering the price.
For those with more expensive equipment? Well, I'll be honest. It can also be used as a second headphone for more all-round use, or messing around in different places. It's true that a hard carrying case would have been great. It's true that the technical level could be better, especially in the scene and separation... but you realize this if you compare it with more expensive things.
Thanks for reading the review. I hope to count on you for the next one!

COMPARATIVES

• Sivga Sv021

The Anser feels more refined and balanced. The SV021 has a warmer sound profile and emphasizes the bass, with a more immersive presentation, though less accurate in terms of detail. The SV021's bass is more prominent, but sacrifices some clarity in the mids and highs in favor of greater warmth. The SV021's highs are less detailed, while the mids, while warm, don't have the clarity and naturalness found in the less color-rich Anser. As for the soundstage, the SV021's closed design limits it in expansion, but gives a more holographic feel at times and feels good to be closed.

• Hifiman Sundara

The Anser has a more musical and less analytical approach. It's more enjoyable. The Sundara, with its magnetic planar driver, offers a more neutral and detailed sound, with brighter and more extended highs, flatter mids, and fast, punchy lows if amplified well. The Sundara's resolution is superior, allowing it to capture micro-details more accurately, and its soundstage is slightly more expansive. The Sundara's transients are faster, and its imaging is similar.

• Hifiman Ananda Nano

The Ananda Nano takes clarity and resolution even further than the Sundara. Sometimes it's too much. An even wider and more detailed soundstage. Honestly don't expect a night and day change with the Anser but it does feel bigger and more expansive. The highs are more extended and the mids more neutral, resulting in a more analytical profile than the Anser which is more musical. Compared to the Anser, the Ananda Nano offers an airier and more detailed sound experience, with better performance in instrument separation and greater accuracy in spatial location. The Ananda's bass is even more controlled and precise, though slightly less prominent than on the Anser.

• Sivga Luan

This is a very interesting headphone from Sivga. It offers a more vibrant and colorful sound presentation than the Anser. It has deeper, less powerful bass, making it a better choice for those who prefer a more immersive sound with impact in the low frequencies. The mids of the Luan are slightly more forward and perceived as thinner, giving it a more energetic and direct character compared to the somewhat more balanced profile of the Anser. The highs, while detailed, can be brighter than on the Anser, and in technical terms, the Luan has competent and, honestly, similar instrument separation and resolution between them. The soundstage does seem a bit bigger on the Luan.
