This hobby is an escapist's dream. Escape from daily routine and distress that's causing you via something as sincere and everlasting as listening to music. I believe that the power of music is still not fully understood since it works in mysterious ways. Allow it to do its magic on you and let your worries dissolve in melody.
Having had the possibility to try so many different sets in a relatively short time I felt obliged to go ahead and express my gratitude by trying to help some lost souls out there, just as I was when I first stumbled upon this weird hobby about wired earphones – so yesteryear! … I thought. Possibilities are seemingly endless and only by getting to meet the right people did I manage to jump onboard the train heading the 'right' direction without getting off-track thousands of times along the way. Make sure to understand the helping person's preferences and you too can find your footing and hit the ground running in no time.
Quick Intermezzo About Me
I won't bore you for too long with personal trivia, however my quick & short background resume goes as follows. Currently I am 27 years old and more in awe of sheer power of music by the day. I have always been moved by music just that slight bit more than average, I'd say. My spending started with a roughly 200€ Bose bluetooth speaker back in my first grade of highschool. What an extraterrestrial thing that was in early 2010s. And it keeps on playing to this day – a true testament of quality. Also sounded fantastic back then, nowadays … yeah, not so much. Lots of BT speakers, TWS, car audio speakers, IEMs, etc., later bring me to this day when I truly consider myself an audiophile. What brings me the most joy beside listening to music is singing, so I am currently participating in a choir and challenging myself with solo vocal covers (check the links in my signature to hear my projects). Unsure where all this leads, but the journey itself is marvelous and
life is nothing but a journey.
My preference lies somewhere in the
neutral camp with just an ever so slight tilt towards warmth, but I try to keep an open mind and truly appreciate any
outliers that dare do it differently and succeed. Our ears vary, so do our brain and tastes. I am an advocate for
respectful discourse, especially in topics that don't even have many objective undeniable truths. Audio is one of those.
My most listened genres are, in no particular order: jazz, singer/songwriter, slow-paced electronica, ambient, rock, metal, blues, trance, techno & pop.
Disclaimer: I have received the Sivga Robin SV021 directly from Sivga themselves. While I understand your concern about honesty, even if I wanted to shill this to the moon and back, I am way too mindful of others' money to overly hype stuff that does not deserve it, so there's that.

How My Reviews Are Structured
Since this is my first headphone review, it will require a slightly modified approach.
I will start off by mentioning the
packaging, accessories, design & comfort, then continue by placing the showcased item in my special
trademarked graphs & graphics (since these are all made primarily with IEMs in mind, I will describe why I placed it as I did underneath each graphic), give it a
score on certain qualities, and
describe the main sound categories to reach the final star score. Those that are seriously considering a dynamic closed-back headphone at a very reasonable price, please do not hesitate to
ask for any specifics you want me to answer via private messaging.
I have left the Robin to burn-in for 100+ hours and listened to songs of varied genres to better convey what one can expect from it. As sources I have been using my FiiO BTR7, Venture Electronics Megatron, iBasso DX180, and Venture Electronics RA2B-FE + Prime DAC (in short, called the 'VE Stack'). Certainly no lack of power and quite a different taste on all. Listening was (mostly) done at a volume ranging between 75-85dB. I am using the stock cable.
Here is the quick and rough description of how I understand
various star ratings:
Do not even think about it

It has too many drawbacks and gets demolished by competition


This item has the potential but feels a bit too bland and has multiple issues



Wonderful item with rare and mostly subjective drawbacks




Eargasmic performance with all the aspects covered at an incredibly high level




Keep in mind these ratings are certainly affected by the
item's price in the overall assessment too. Sometimes that will result in slightly higher score than based solely on my scoring of bass, mids, and treble, while other times it results in a slight penalty if I deem the item a tad overpriced.
In layman's terms - anything rated below 4 stars overall does not get a space in my regular rotation and is either stored and revisited some time later again just to see if my thoughts have changed, or it gets gifted.
I am still catching my stride on how to describe the sound aspects in
a clearer way. It is a slow but enjoyable learning curve. I am attempting to make my reviews as
ballast-free as possible. The playful yet useful graphics were the step in the right direction, I feel. Capturing the essence of sound characteristics in a less wordy way is next on the list. We all have our own busy schedules and I understand reading a review for 15+ minutes is in (nearly) no-one's interest.
Let's Get Going!
Packaging, Accessories, Design & Comfort
Unboxing is quickly dealt with and you're free to enjoy your new headphones! These come in a normally sized box which hides the headphones inside a simple bag and not much else. Sadly, these do not come with the great case that came with the Luan, but that's not too big a deal considering these are literally half the price. The headphones, a cable + the 3.5 to 6.35 adapter. No real complaints at this price point, but if you were hoping for a jaw-dropping unboxing, this isn't it and you should rethink your expectations.
These are a
dream to wear (about as comfortable as the Luan (on the second pic below) which has better and larger pads to distribute its weight and dissipate heat better) with what feels like completely weightless cups and a well designed headband. At 275g, and equipped with their great headband and plush-feeling earpads (although clearly pleather and some warmth might accumulate in warmer months) allow for a fit-and-forget feel. Earpads, while not the deepest, widest, nor tallest, should fit most ears. I must say that the lower weight is also slightly at the cost of lower build quality than the Luan, but still very acceptable and they do not feel like they want to fall apart.
I'll leave the
design for you to decide, but in person these are truly sexy with their wooden and lacquered cups, nice tone of beige for the pads and headband, and a cool non-glossy silver construction, so overall a very understated and classy look that could easily pass as a much more expensive item.
Graphics, Graphs & Scores
To better represent where they fit in, I am adding the
Sivga Luan, their open-backed offering, alongside.
These will lean very warm and soothing and be a step below the Luan in technicalities. Even more so than the open-backed bigger brother, the
Sivga Luan.
Six Basic Traits
Comfort is mildly better on the Luan which has larger and plusher pads as well as the fact it is open-backed and breathes better.
Isolation is obviously right on the contrary.
Bass, while bigger and more impressive on the Robin, is better textured on the Luan,
midrange is more cohesive and precise on the Luan,
treble is livelier, but a bit more sibilant too.
Cohesion is better on the Luan. All these differences were somewhat expected and not too large considering the relative price difference. These fit two different use cases.
Magic Balance Boards
Quarter Circle Playground
Laidback and pretty
sophisticated unless the song depends on ultimate detail retrieval and crisper treble.
Overall scoring ended up looking just okay due to Robin's tuning and closed-back nature which is bound to bring positives and negatives. A departure from what I maybe expected, knowing how wildly daring and unique their Sivga Nightingale IEM I have reviewed recently is. No real complaints, though, this is an all-rounder headphone to go with their crazy flagship IEM or any of their open-backed HPs.
Sound Descriptions
The obvious categories will be subcategorized into a few important aspects. It is impossible to just proclaim the bass as great or not,
there are levels to this hobby and since you're reading this review, you've obviously fallen deeper into this rabbit hole than many.
Bass
(some songs I used: Soldier of fortune by Deep Purple, Summer by Emeli Sande, I'm in Love by Ayo, House of the Rising sun by alt-J&Tuka, Infinity by DJ Pastis&DJ Ninu&Wasi Distorsion, Kuwait by Mazde, Drum solo by Manu Katche, Hislerim by Serhat Durmus&Zerrin, Animamundi by The spy from Cairo)
Quantity vs quality: It feels quite bassy overall, but that is due to the closed-back nature and the low midrange dip centered around 500hz. The quality is good considering the price, but don't go in expecting scalpel-like precision or ultimate refinement.
Rumble: It can get low, but it's not moving as much air and staying as composed as someone who's into subbass-rich music might prefer.
Attack: The note edges are rounded and won't feel too snappy. It's a calm sort of bass that is always there, but not calling for attention.
Decay: Smooth and appreciably natural, but again lacking a bit in amusement. It's never troublesome, just not marvelous.
Boominess: I went into it expecting it to be boomy because of slight boominess of the open-backed bigger brother I had tried before, the Luan, and thankfully I was wrong. This is boom-free.
Bloatedness: Just slight. But it might feel that way due to those first overtones being so attenuated right in that dip which the graph shows well.
Mids
(some songs I used: Creep by Haley Reinhart, Rosita by Coleman Hawkins&Ben Webster, Vidda by Ole Edvard Antonsen, Long after you are gone by Chris Jones, Writing's on the wall by Tom Ball, Dream on by Morgan James, Lonely island by Amble, Exhale the ash by Ulcerate, Free bird by Lynyrd Skynyrd, Eyes don't lie by Tones and I, All about you by Sophie Zelmani)
Timbre: Getting this right is crucial in overall acceptance of any set. Always a sensitive topic. Timbre is not an easy one to unfold and pack into these little forms we call words. We also have a different understanding of 'correct timbre'. Hearing the instruments in multiple settings and played by different artists is a must to really get familiar with their intricacies. The bassier instruments can be just a bit strange due to tuning choice of low mids, but certainly not awfully so. Brass could be more incisive, but I know that's always a double-edged sword cause it can quickly turn into a shoutfest with what is surely a lower-end driver considering the price.
Forwardness: A healthy medium. They are neither buried far behind the rest of the spectrum, nor do they feel forward in either placement or amplitude-wise. What then makes this a good listen is that they're never overshadowed or feeling subdued.
Clarity: Not spectacular, but decent enough for a closed-back headphone in this price range and especially decent enough for the musicality and chilled listen this provides. I would not be choosing these to do any deep dive analysis of any orchestra.
Vocals: They lack the ultimate detail to catch every breath, lip smack, saliva build up, … Every vocalist is just a tad smoothened out, whether it be a soothing baritone, a soaring soprano, or a screaming metalhead. Very similar to Luan.
Note weight: I'm most sensitive to how the piano is played back. Hearing a grand piano live you can tell just how much body each note carries and how rich it is in under- and overtones. Note weight is one of those risky topics and it quickly segregates the field in two camps, those that prefer a thicker, rounder note weight and hence a more analog approach, and those preferring all-BA sets (in IEM language) because those usually have a quicker, less hefty character and a more digital sound. Mind, those are very very severe simplifications of this layered, 50-shade-of grey topic just to carry my point across. This is often where headphones do better than IEMs. Why? Because physics. It's a combination of having larger drivers moving more air and the effect of pinna which is absent on IEMs. In a nutshell, this is why the Robin is definitely grander in note weight and their physicality than IEMs and fuller even than the open-back headphones.
Treble
(some songs I used: Vidda by Ole Edvard Antonsen, Want by The cure, All about you by Sophie Zelmani, Morning bird by Sade, Animali in Marcia by Gianluigi Trovesi, Ain't no love in the city by Robert Haglund, Barbados by Arne Domnerus, Oh Dear by Sophie Zelmani, Liberty by Kerenza Peacock&Timothy Ridout&Hum Watkins, Shivers by Ed Sheeran)
Crispness/sharpness: A mix of multiple qualities hidden all the way from upper mids high up into treble. There is no straight-cut rule to tackling this and having it fit all ears and preferences. Despite the graph showing quite a bit of energy up in high mids and treble, these are never bright-sounding or in any way crisp nor sharp. If you prefer the more risky sound where some songs, like Shivers from Ed Sheeran, sound right on the edge of comfort, these are not for you.
Sibilance: Well handled. Even the worst of offenders in modern pop, again like Shivers by Ed Sheeran, get by without any painfully sibilant moments. This area is skillfully attenuated despite not really looking that way on graph. That is also part of the reason why it feels calmer in its presentation of instruments that make use of this area.
Naturalness: It lacks some finesse to truly feel natural with brass, strings, hihats, cymbals. Those become a bit wetter sounding than I find natural and lack the spice and zinginess.
Air: Not happening. Treble is veering far to the shy side. Also, I have yet to hear a headphone or earbud do this area well, or okay even. So those of you searching for that treble shimmer which has an almost undescribable, magical effect in some scenarios, look elsewhere.
Extra
Fun factor: This is a longterm enjoyable listen, not one that wows immediately by having any incredible standout strengths. So yes, fun, but for when you want something comfortable to lay back with and shuffle through your playlist.
Q: What kind of source to pair it with?
A: Do not add any warmth, so I would say neutral to neutral-bright is what would suit the Robin the most.
Q: What genres are its strength/weakness?
A: It does fine with most, but this won't be the most dynamic and quick sounding headphone, so perhaps avoiding the 'extremes' such as metal or classical is the way to go.
Summing Up The Sivga Robin SV021
This was a pleasant surprise, yet I am unsure why. I have tried quite a few Sivga products before - all were very much worth their price and hugely competitive in their segments. Despite that, I was worried that enclosing their house sound which is usually low-midrange-rich, would result in an overly thick listen and thus be well out of my preference or neutrality for that matter. Thankfully, they are well aware of what they're doing and these manage to impress with their warmth yet decent all-aroundedness.
Thanks for reading and stay wonderful.
