In terms of driving factor, Sivga Robin is fairly easy to drive, and sounds sweet right out of a smartphone, but giving them some extra power, as well as a higher quality source will result in a better listening experience, as they are fairly resolute. The overall drive factor makes them easy to drive from a FiiO M11 PRO, iBasso DX160, but also high-end DAPs like iBasso DX240, Astel & Kern SE180, Lotoo Paw 6000, and Cyrus One Cast. The earpads are detachable easily, and you can replace them, plus the 50mm driver with 32 OHM Impedance and 105dB SPL is no problem even for FiiO BTR5 MK2, or Shanling UA2. 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. Hiroyuki Sawano – Pretenders (01:18-01:47), a lot more natural tonality/timbre and isn’t veiled on the Phoenix. The midrange of the FiiO EH3 NC has a warmer tonality with a smoothed out character. The SIVGA SV021 is slightly more neutral, bright and energetic in direct comparison. The lower midrange of the EH3 NC shows a bit more body and depth when I do listen to male vocals or to instruments such like acoustic guitars or violas. When it comes to the upper midrange, I can say that the SV021 is more highlighted and detailed in this area, which adds it a slightly better sense of transparency and airiness. The SV021 is also more suitable for female vocals or instruments such like violins, flutes or pianos that do need more energy in the upper midrange area. It’s a balancing act that gives the vocals presence and clarity, but when it goes too far, can sound a touch harsh. The Oriole’s lean signature does well with fast, energetic music.

As with other models, Sivga opts for a build using wooden cups and (faux) leather covered headband and pads. The Robin SV021 is generally a warm-sounding headphone. It has rich bass, vocals are not recessed and the trebles are crisp and clear. It’s fun and musical in general; and I think it would be a good headphone for casual listening, media consumption, and even gaming. I just don’t recommend this for mixing and critical listening session. You’ll have to look for a neutral and natural-sounding headphone, like the LCD-X, if that’s what you are after. Mids: Hiroyuki Sawano – OldToday (01:25-01:52), instrument tonality and timbre are a lot better on the D1100. Vocal tonality is a bit better on the SV021 but sharp, timbre is a lot better on the D1100 and is more forward and not veiled.Before I forget, the SV021 is transparent to a certain degree. Even though it’s a fairly easy-to-drive headphone, the DAC and AMP (source) may affect its sound signature. During my tests, I used Schiit’s Jotunheim and Luxury & Precision P6 DAP. I don’t think it would be a good idea to pair it with a warm-sounding source, not unless you want to emphasize further its bass region. Price and Where to Buy
