The Robin embodies the ‘craftsman spirit’ with its wooden ear cups finished with a piano gloss.
The Robin are the latest closed-back headphones from Sivga. Similar to some of Sivga’s other models, the Robin feature wooden ear cups with a high gloss piano finish and metal headband. This is indeed a combination of classic and modern design, giving the Robin a unique appearance.
The Robin are powered by a pair of high-efficiency, in-house designed, 50mm dynamic drivers. Sivga designed the closed-back Robin to be easily driven to enhance their portability.

Packaging
The unboxing experience of Robin is definitely enjoyable. The headphones are well-packaged in a black box, with the brand and model number printed on the front. On the back of the box, the technical specifications are printed in Chinese and English. The tagline of Sivga is printed on the back of the box too – “Created with Craftsman Spirit.”
The “spirit” can be immediately felt when you open the box.
There’s a hemp storage pouch included in the packaging. However, I find the protection provided by the fabric storage pouch to be insufficient. Perhaps, a simple hard case would serve the purpose better.
In the box
- Sivga Robin headphones
- Detachable cable (1.6m)
- Hemp headphone storage pouch
- 3.5mm to 6.35mm conversion adapter
Cable
The Robin come with a detachable cable, terminated with a 3.5mm unbalanced jack. On the headphone side, Sivga uses 2.5mm dual-mono tip-sleeve (TS) jacks. This type of jack is used by HiFiMan on their older HE4XX and Audioquest Nighthawk. The cable is well insulated with a layer of fabric at the outer layer. To reduce the strain stress exerted on the 3.5mm jack, Sivga includes a spring as strain-relief to improve overall durability.
Design
The eye-catching design of Robin is definitely one of their selling points. Sivga’s extensive experience in designing and producing wood ear cups is evident in the well-polished, shiny gloss finish. I could not stop myself from touching the ear cups immediately when I removed them from the box.
The surface is as smooth as a piano.
The headband of Robin is made of lightweight metal and matches well with the classic-looking ear cups, yielding a unique and modern design. The headband cushion and ear pads are light brown and thick, providing good comfort for users. The ear pads can be removed and replaced easily by twisting.
Comfort
I am not a frequent full-sized headphone user because the majority of headphone ear cups are too small for me. However, the Robin’s thick pads do not “press” on my face when I am wearing them, and the depth and width of ear cups are sufficient to house my big ears too.
The Robin provide me with a high level of comfort, and allow me to have them on for hours.
The headband is well-padded and appears to be the same material as the ear cups. The cushion distributes the weight of the headphones evenly on my head and I do not feel any hotspot pressure even after long hours of wearing.
Internals
The Robin are powered by a pair of 50mm dynamic drivers. Sivga designed the dynamic driver in-house with an ultra-thin diaphragm made of polycarbonate (PC) and fiber.
Robin Sound
To analyze the sound quality of the Robin, I mainly used my desktop setup – a Topping E30 DAC with a iFi Audio Zen Can amplifier. After several hours of auditioning, I observed that despite the Robin being easily driven by portable DAP such as my Lotoo PAW6000, the performance from a more powerful source yields better results.
You’ll need a powerful source to obtain the maximum capability of the Robin.
The sound signature of the Robin can be classified as neutral and balanced. The three main parts of the frequency spectrum (bass, midrange, treble) receive equal amounts of focus. The overall sound signature does not alter much by changing the source, but the differences to the specific parts of the frequency spectrum are significant. I will elaborate more shortly.
The soundstage of Robin is above average. With an adequate amount of expansion in each axis, they provide users an experience of three-dimensional headroom. They are arguably better when compared to some open-back headphones that are tuned to sound more “in your face.” I do not feel any fatigue after long hours of listening.
Out of the box, I immediately observed that the detail retrieval capability of the Robin is extraordinary. In some of the tracks that I always listen to, I found “surprises” with the Robin. To confirm their capability, I compared the sound with some of my better IEMs. Those newly noticed details are indeed more prominent and are better highlighted on the Robin.
I look forward to re-listening to those tracks again with the Robin to find more “surprises” in the music.
Bass
The bass performance of the Robin can be described as speedy, responsive, and accurate. Whenever a bass note is hit, the Robin can respond energetically and accurately without affecting notes in other frequencies. This accuracy in the bass preserves good clarity and transparency in the overall performance. The mid-bass is not boosted to enhance warmth, which improves the overall cleanliness of the sound signature.
The quantity of the bass is only average and I personally do not think the Robin will be sufficient for bass-head audiophiles. The Robin have good extension in the sub-bass, creating a good depth that contributes to the three-dimensional soundstage. I can feel the rumble from the sub-bass as a small punch on my eardrums. They are not the kicking type.
Midrange
Thanks to the precision and accuracy of the bass, the midrange of the Robin has a high level of transparency with an absolutely low level of coloration. I get exactly what the track has without any blending, mixing, or coloring from the headphones. It is as good as getting a photo in RAW format from your DSLR.
To continue the photography analogy, the midrange of Robin can be Photoshopped by swapping the source, either a DAC or amplifier. Using the Topping E30/iFi Zen Can combo the midrange of the Robin is neutrally balanced, neither warm nor dry. When I swapped the amplifier to my ALO Audio RX Nickel edition, the midrange shifted toward the more analytical side.
The Robin are capable of handling both male and female vocals well. Male vocals are natural, with a good body, and are well-segregated within the mid-bass with no bleeding. Female vocals are airy, spacious, and engaging. They maintain politeness towards my eardrums with no irritating piercing or harsh sibilance in the vocals.
Treble
The treble of the Robin is well-extended with a good amount of space. The presentation is smooth and airy. Robin handle the decay of the super-high frequencies decently with negligible distortion. This contributes to the high level of cleanliness and makes the treble an enjoyable component and equal partner in the overall sound.
With the Robin, I can really pick out guitar plucking and cymbal crashing in the music, without a need to focus on these aspects. They are brought to the same level as the vocals and bass. With help from the wide soundstage, all these components play harmonically with each other without collisions.
Comparison
Audio Technica ATH-M50X
The Audio Technica ATH-M50X could arguably be the most competitive challenger for the Sivga Robin in the same price bracket. Launched in 2007, the ATH-M50X are still in production, and Audio Technica releases new limited editions of them from time to time. I have owned my pair of ATH-M50X since 2015 and they still serve me as a good pair of monitoring headphones.
The sound signature of the ATH-M50X is similar to the Robin. However, the overall performance of the ATH-M50X is duller and colder, while the Robin are more energetic and engaging. The Robin bring the music to me in a more lively form.
In terms of detail capability, both are at the same level.
The ATH-M50X focuses more on mid-bass, creating some bloat in their low-end performance. The Robin have a more balanced bass, focusing equally on both sub and mid-bass. This creates a drastic difference in terms of soundstage. The soundstage of the Robin is more three-dimensional as compared to the ATH-M50X’s linear soundstage.
In terms of build quality, the ATH-M50X are made of plastic and the ear cups are shallower. The modern and fashionable-looking Robin are definitely more eye-catching for consumers. The deeper ear cups and better cushioning on the headband are more comfortable as well.
The Robin are an attractive choice for headphones below USD$200.
Where to Buy
Conclusion
Sivga has achieved numerous successes with the release of the Robin – combining eye-catching design, comfortable wearing experience, and outstanding sound quality. The Robin are definitely state-of-the-art headphones within a reasonable price tag under USD$200. Within this price range, I really can not find anything that is close to the Robin in terms of physical appearance and sonic performance.
For those who are looking for a pair of entry-level audiophile headphones, the Sivga Robin should be on your list. The maturity of design and tuning from Sivga is totally worth the price. You will not be disappointed by the Robin!
I got both colors. I like the dark as it is more classy looking.
You hailed the sound profile. It is very three dimensional and balanced from top to bottom.
Yes, I actually prefer the black version too. The soundstage is indeed very impressive for a pair of closed-back headphones.
Very nice review. I purchased the Peanut Butter colored version instead of the Chocolate colored version The Robin’s sound signature is really good, yet they are a tad weak in the lower midrange. This somewhat colors male vocals. This was an easy fix in EQ since I also prefer a bit more lower bass. I simply used a low shelf filter at 40Hz with a gain of 4 and a Q of 0.25, resulting in a very slow rising 2dB of gain for stuff below 1kHz. This brought the lower midrange back to neutral and gave me that bit of extra bass which I desired. These headphones are by far the most comfortable headphones which I have ever worn. I can easily wear them for hours while binge watching Netflix.
