Sivga Robin SV021 Review

Sivga Audio is a Chinese company that appeared on the Hi-Fi audio market relatively recently, in 2016. And frankly, we hadn’t heard much about them until then. However, more and more often in various reviews and forums we see positive feedback about their full-size headphones, mostly in the entry and middle price segment.

And now it’s time for us to take a personal look at one of the brand’s models. Today it’s the Sivga Robin SV021 – newest and fairly affordable wired headphones designed primarily for home listening. Let’s take a closer look at these headphones and try to find out how exactly the young Chinese brand can compete in this market today.



Sivga Robin SV021

The Sivga Robin SV021 come in a sturdy cardboard box with brand and model name printed on the front. On the reverse side of the technical specifications and the slogan “Created With Craftsman Spirit”.

In the box:

  • Sivga Robin SV021 headphones
  • Cable (1.6m) 3.5mm to 2.5mm
  • Headphone storage pouch
  • 3.5mm to 6.35mm conversion adapter

The package is not the richest, but here it is worth remembering that we are talking about the budget segment. Moreover, everything that is in the box is made really high quality and does not cause any complaints, just as it does not cause a feeling of economy or cheapness. Basically, the kit contains everything you need.

An unexpected feature – the bag for storing the headphones is made of non-standard material, apparently natural linen, which, given the leather, alliumium and wood in the bowls as if to continue the concept of natural and environmentally friendly product.

It is worth paying some attention to the cable. For some reason, Sivga decided to use a non-standard cable with which, in case of replacement, you will have to tinker, because it is not so easy to choose one on the market. On the headphone side – 2х2.5mm, on the source side – 3.5mm.

For a more convenient connection, special recesses are provided on the cases. The contact is reliable, the snapping into the cups is very clear. It also disengages with a good and noticeable effort. The length of the cable is standard 1.5 meters, has fabric insulation. Made qualitatively, no complaints.

The design of the Sivga Robin SV021 is quite discreet and at the same time very refined. The headphones are quite light (275g) with an abundance of quality materials immediately evoke a sense of quality product.

The headband is covered with soft pleasant leatherette with white stitching.

The cups are connected to the headband with an aluminum c-shaped mount.

Adjustment of the bowls is stepped, well fixed and accompanied by clear, pleasant metallic clicks.

The bowls are made of natural wood with the company logo on the outside. Everything is processed very high quality and very pleasant to the touch. According to the manufacturer, the bowl wood housing is handmade with fine workmanship – and it’s really visible and felt as soon as you pick up the headphones.

There are two compensation holes on the top of bowls.

The earpads are completely made of leatherette, there is no perforated leather or textiles here. At the same time they are very soft and comfortable, have the effect of memory.

Given the low weight of the headphones and the extremely well-designed ergonomics, the design has a high level of comfort. Sivga Robin SV021 are really well-designed headphones that combine quality materials and excellent ergonomics. A few hours of listening to music will not give you any trouble at all.

We were pleasantly surprised by the high level of comfort of the Sivga Robin SV021, here we can give the highest rating to the developers. Similar comfort is far from always observed in the middle and even high segment, while Sivga provides such a level in a budget model priced at only $179, a really great job.

The Sivga Robin SV021 has 50mm drivers of the company’s own design. The overall sound presentation is very balanced, with excellent resolution and micro-detail that doesn’t overflow but stays in place, providing a very precise and musical experience. The virtual scene is of medium size, it can also be called very balanced and calibrated. All instruments are in place and have good separation. An unusually high resolution for dynamic headphones of this segment is immediately noticeable, every clap in the hall is clearly recognized and has excellent positioning in space. Thanks to this, stringed instruments show their unique timbre but do not fall into too intrusive microdynamics – the balance is superbly maintained.

The headphones have an Impedance of 32 Ohms with a sensitivity of 105 dB, which allows them to warm up quite well with almost any amplifier. However, it is worth noting that the headphones are sensitive to a quality source and are able to change their sound color for the better as soon as you connect some good mid-range headphone amplifier to them.

Low range

As is typical of dynamic models, the bass is somewhat pronounced here, but it balances well in the overall sound picture. It is well defined and tangible in the composition, has a rather elastic structure and unobtrusive feed. Despite the rather tangible massiveness of the low range, you can well make out various technical manifestations. Try listening to Jaco Pastorius classic track – The Chicken – nice check for low range quality. And here Sivga Robin SV021 show excellent intelligibility, dynamics and readability of Jako’s entire bass line. No hum or mush, and just great balance with a mid-range.

Mid range

The mid range is very warm and lively. Well balanced between low and high, has a large number of correct overtones. On some tracks, you can feel the vocals slightly ahead, as if the vocalist is standing closer to you. At the same time, the feeling is very organic, we must pay tribute to the excellent tuning by the Sivga sound engineer, the balance in the entire middle range is remarkably sustained. Listen to how much volume and separation the guitars have in the track by Larry Carlton and Robben Ford – Monty (Unplugged). You will also be able to feel what it means when all the ranges are well matched and have a really musical resonance. An extremely good indicator for the budget segment of headphones.

High range

Everything is pretty standard here, the headphones do not grab the stars from the sky, but they show good acoustic naturalness. The entire high range is quite detailed and fast. You will not hear harshness or sandiness here, as well as excessive brightness. Everything is perfectly balanced and has a perfect match with the mid-range. We would like to hear a little more reverb decay here, however, it is worth noting that the headphones here also show a level well above their segment and the average in this price category as a whole.


Sivga Robin SV021

Sivga Robin SV021 is a good example of the balance of quality, sound and price in the budget segment. Great comfort, aesthetically pleasing design and a really exciting sound simply can not leave this model without attention. Great job Sivga!
