Bass fans will maybe want to give these a miss but for anyone looking for reliable balance, the Sivga Robin know how to hit the spot nearly every time.

Sivga Oriole – Sweet Herald of Spring - Headphonesty Review: Sivga Oriole – Sweet Herald of Spring - Headphonesty

This will require a brighter and details heavy source to completely shine through. With T01 there was better separation and mids congestion slightly removed to make it a better listen. There is more treble energy and the proper ‘v’ shape of the headphone stage comes out. The Female vocals have now better extension too. Sub-bass is still very light but the bass is now more controlled and punchier. R01 don’t use with this. Corey King’s vocals in Fade from Fly Moon Die Soon and Zara McFarlane’s in Everything is Connected are served well by the warmth and smoothness on offer, with the Sivga giving vocals good presence within the soundstage. Bass is presented with solidity and depth, while at the top end of the frequency range the warm tone does reduce the sharpness and brightness of those highs. Many times, as a reviewer our time is at a premium. Especially if this is a hobby, which it is to the vast majority. That said, if you keep organized you can give initial impressions and then burn the unit in while other units are being reviewed. I always burn units in, whether called for or not. It is my philosophy that users want to hear how the unit sounds in a year’s time as well as brand new, should there be any change. Many manufacturers advocate burning their units in. Some do not. Sivga made no such charge, but after an initial listen the unit was put onto my Shanling M0 for 75+hrs straight of music. Personally, I did not hear much change, and would be averse to stating any changes did happen based upon my shortcomings. That said, the initial listen was favorable as was the burned in listening. 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. Mids: Hiroyuki Sawano – OldToday (01:25-01:52), instrument and vocal tonality and timbre are leagues ahead on the 1AM2.IN CONCLUSION:​The Sivga "sv021" Robin is a good upgrade over the infamous ATH-m50x with better bass, treble, instrument separation, soundstage, and almost everything else (expect for bass speed).

I recently reviewed the far less catchily-designated SV023 (with no corresponding bird name) and was impressed by their relatively ‘safe’ and well-mannered sound. The SV023 are about 2.5 times more expensive than the Oriole and sport the brand’s higher-end headband and 300 Ohm dynamic drivers. The Oriole have a clean and elegant design. The Sivga Robin SV021 have been loaned to me by Keydis, the official distributor for Sivga and Sendy Audio (their sister brand) in Spain. They have not made any requests and my review will be as honest and unbiased as possible, but it is worth noting that these headphones have not cost me anything to try out.

Listening To The Sivga SV021

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

Occasionally, I found myself turning my head because I could feel some sounds around me - instruments are well-positioned to create an impression of surround sound.

I simply could not write a review with the horizontal rotation problem present. I knew that this headphone is capable of much, much more (because once I physically pressed the ear-cups against my ears, the performance was significantly better). Robin has a 10dB bass boost, recessed lower-midrange, an upper-midrange forwardness of around 8dB ear gain and a brighter, sparklier and zingier lower-treble and upper-treble character. Robin's signature's main focus is on bass punch and treble sparkle than lower-midrange body fullness. It has a leaner, open and airy presentation with instrument tonality that sounds like you're listening to a live concert in an arena than an accurate and natural sounding studio. Compared to a reference target curve, the Harman 2018 AE OE target, it has more sub-bass, significantly more mid-bass and upper-bass in the 60-250Hz range, a dip in lower-midrange around 500Hz, less ear gain (upper-midrange forwardness) in the 2-5kHz and brighter lower-treble and upper-treble by around 5-8dB. Stage, etc: The Sivga robin has a nice wide soundstage. there is very good separation and accuracy, this makes it great for movies or games. One of the reasons headphones and earphones in India are more expensive than overseas is because of the Goods & Services Tax in India.
