I listened to the Robin SV021 for a few minutes right out of the box. And I noticed that the treble was a bit sharp. It was generally okay to use and listen to out of the box, but I feel that breaking it in would help even things out and let the driver “stretch out” its diaphragm and move its coil more. Bass: Djuro – Drop that bass (01:15-01:30), similar extension but more rumble on the SV021. Punch quantity is also higher on it but tighter, faster and a bit more textured. Tonality and timbre are a lot better on the Phoenix. In terms of detail, the SV021 had good macro and micro detail, although the macro detail was much better, as expected from a budget headphone. That said, although the top end detail was slightly rolled off, removing some of the air you get from more expensive offerings, there was enough there to give me a “big picture” view of the recording space. One of the reasons headphones and earphones in India are more expensive than overseas is because of the Goods & Services Tax in India.

Collin at Sivga introduced the Robin SV021 to me as “neutral and balanced”. It is crystal clear that they are not and, in fact, they are far from being neutral, with a heavily V-shaped signature that sees an overpowering bass section counterbalanced by an aggressive treble area. This is all produced by a 50 mm dynamic driver made of polycarbonate and fibre. The sub-bass has pretty good extension but it doesn’t hit very hard. You get a fairly light rumble that is satisfying enough but is nowhere near basshead level. Listening to “A Dive Into Ether” by Nibana, the SV021 still manages to sound like a balanced headphone while some other headphones or IEMs (shout out to Shozy Ceres) crumble under the weight of the bass. Why so Serious?” by Hans Zimmer — 3:26. Like with the mid-bass, SV021 has a deeper response with more presence. There is more quantity and more volume (not referring to loudness) in the sub-bass.Technicalities: Shiro Sagisu – Hundred years war (02:24-02:57), wider on the SV021 but a lot deeper and more holographic on the 1AM2. Macro detail is better on the SV021 (due to the massive treble peaks) but imaging, separation and timbre on the 1AM2 is outclassing the SV021.

You can expect them to present a refined listening experience. The audio quality exhibited by these headphones is a beautiful mix of musicality, technical brilliance and high precision. Hiroyuki Sawano – Lose (string version) (01:22-01:59), Cello tonality, timbre and texture are better on the KPH30i but cleaner on the SV021. Violin tonality and treble-extension are better on the SV021 but is sharp, timbre is a lot better on the KPH30i. 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.When I handed her the Orioles, I asked her what price range she thought they might belong to. Her guess was five times more than reality. That is high praise for Sivga’s construction. Sound quality (it is very bad before bending, and while it is much better after all of the extreme bending, after comparing it to other similar options, it doesn't really hold up against or with them) At the price that these headphones come in at, they offer a very reasonable deal for a set of headphones that gives an extra flavour to the collection.
