The strings were also rich and full-bodied, which demonstrated how well these headphones reproduced timbre. Due to the top-end roll-off, I didn’t quite get the micro-detail one would get from a more expensive headphone (like the SUNDARA, for example), but the strings were still pleasing. Instrument separation and layering are decent too. Thanks to the wide soundstage, instruments do not sound compressed or "in your head". Instruments are well spread out with the vocalist presented in the middle.

The SIVGA SV021has an impedance of 32 Ohms and sensitivity of about 105dB, which looks pretty efficient on paper. However, I suggest you to pair it with sources that do have better levels of amplification, such like portable or desktop amplifiers (xDuuo XA10, FiiO Q5s, PALAB M1-Mini) or powerful DAP’s (iBasso DX220 MAX, iBasso DX300) that do offer a much better synergy and overall sound performance. The positive effect of such sources was especially audible in the lower frequency register. I don’t know, maybe I’m just being too harsh due to the comparisons and overall experience I got with the SV021. I know Zeos loved them, but then, how many products are there that he didn’t like… Not too many.Hiroyuki Sawano – Pretenders (01:18-01:47), mid-bass quantity is a lot higher on the D1100 and is more textured. Faster and tighter on the SV021 though. But more tonally accurate as well as better timbre on the D1100. The Robin SV021 is not a smooth-sounding headphone. It’s a bit crisp or sharp due to the slight treble and clarity emphasis. Although, I don’t think that its treble is well-extended, or (overly) bright. Its treble region hasn’t reached the level of something like the Grado SR225e, which is a bright-sounding headphone. Hard to believe this kind of quality is available for such a low price-(in terms of audiophile dollars).

Even though it is quite a bit away from reference-neutral, it performs quite well as a fun and musical headphone. It has a nice musical quality to it where it not only has good bass punch but even the livelier treble, which isn't the most linear, sounds vividly musical and exciting in most songs. The combo of effective passive isolation, small size, lightweight, high-efficiency, and rotating earcups make the Oriole an excellent choice for commuters and portable listing.

Build quality.​Be it the rosewood wooden ear cups, the matte finished metal yolk and headband adjuster or the high-protein leather headband and ear cups, Robin oozes of good boutique build quality and all the components look and feel high-quality and premium for the asking price. Overall, Robin is better in terms of bass, dynamics, and soundstage width, but k371 has the better midrange, tonal balance, and resolution.

Would LOVE to be able to get these earpads for other models--seriously--these are the most comfortable earpards/earphones ever----- Bass: Djuro – Drop that bass (01:15-01:30), extends and rumbles a lot more on the 1AM2. Punch quantity is also higher on the 1AM2 while texture, speed and tightness are better as well. A lot more tonally (sounds veiled on the SV021) correct as well as more natural timbre on the 1AM2.The color scheme of tan leather juxtaposed against the aluminum frame and rosewood cups makes the Sivga SV021 look more premium than you would expect for the cost. The matching tangle-resistant detachable cable adds to the luxurious look. One of the reasons headphones and earphones in India are more expensive than overseas is because of the Goods & Services Tax in India. The Robin’s treble is light and airy. Just like the bass and midrange, the treble position is a little recessed and not upfront. The treble extension is good, showing ample decay and trailing harmonics on notes.

Note - As I stated before, Robin's sound signature's perception depends on tightness of clamp force based on head size since its lowest headband setting isn't as tight as required for a snug fit in case of smaller head sizes. As a result, if you don't have a snug fit, you'll perceive a bit more treble and less of sub-bass rumble. While pleather pads tend to deteriorate over time, the good news is that the earpads are easily replaceable and simply slip on the cups. The cups are simple but well made. Internals The bass on the SV021 isn’t articulate, but this headphone gives you more than enough mid-bass punch to make things interesting. However, you don’t get the sub-bass rumble as you would get from a Meze 99 headphone.When it came to Dynamics, the Macrodynamics were really good. Microdynamics were sufficient enough to give me an inkling of spatiality. The difference between quiet and loud passages was quite pronounced, especially for a headphone at this level. Mids: Hiroyuki Sawano – OldToday (01:25-01:52), instrument and vocal tonality and timbre are leagues ahead on the 1AM2. The SIVGA AV021 shows a pretty strong treble emphasis with good level of extension and detail retrieval for a product at his price range, while it is unforgiving if you listen to songs with poor record quality. This tuning makes the general presentation of this area energetic and highly dynamic. People like me and Zeos receive free review samples, once again, making it very easy to overlook the true value of something.
