Great all around
Pros: Build quality far above its price point! Comfort is superb and the sound signature is super enjoyable. Looks are pleasing to my eye.
Cons: cable is okay , a little stiff.

Let's start by saying the Robin is not only built solid but it's beautiful as well. A fine example of a wooden headphone.
Inside the simple box you get the headphones, a cable of matching color, an adapter and carrying pouch.

Comfort wise, the pads are plush and fit ones ears well, there is decent isolation but mild sound leakage at high but not recommended volumes. I could wear these all day depending on how hot it is outside.

Sound:
Starting down low the Bass is well represented with good depth and some thickness, still it maintains control and in my opinion is some pleasantly smooth sub-bass, the mid-bass slam is speedy, warm, and impactful. Much fun here for bass lovers.
Moving to the mids, the midrange presents well placed and vocals particularly male are lush and pleasant. as with most V-shaped headphones there is recession in the lower mids.
The highs are energetic with nice air and sparkle on top, details are good, and the treble doesn't get overwhelming.
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.

Afterthoughts:
The Sivga Robin is a good quality set of headphones for the price, and they have good looks with an enjoyable signature that is great for various types of music and media. I like them very much.

from Denon AH-D7000 to Denon AH-D7200 to Sivga Robin SV021
Pros: Sivga Robin SV021:
- very soft and "fluffy" earpads, makes it very comfortable to wear the Sivga for many hours.
- light, but durable
- good materials
- good cable and just long enough, not too long
- costwise cheap
- soundwise very good, just keep and want to keep on listening to music
Cons: None for that price and quality and comfort
I had / have a pair of Denon AH-D7000 since 2012, which I used rarely with my Hifi System and enjoyed the sound alot.
One day the right side did not make any sound, not even noise, or scratch etc. Brought to a hifi shop and was told the right driver is kaputt, and there are no replacmenet parts. (I do not believe them that they opened and tested them, but cannot proof it).
I found brand new Denon AH-D7200 for a good price and ordered them. I also check several reviews on over-ear headphones and stumbled on Sivga Robin SV021 by Z-Reviews. He just kept complainig that there is nothing to complain about that headphones and they are just fun to listen. So I ordered one and compared to the Denon AH-D7200 they sound for my personal opinion much better, brighter clear, good in bass, great in vocals. The Denon AH-D7200 is more like "Etiquette in a fancy club" ".. hmm sir would you mind to listen to some good music.." and is still holding back. While the Sivga Robin SV021 are just say "... Lets have some FUN..."

Hello Ace Bee, thanks I have not seen that at all.

Great review, I owned the old Denon line as well as the new Fostex headphones like X00 and TH600 and TH900. I agree the Sivga offers a great alternative to those wooden headphones. The X00 sounded muddy to me and I'd take these SV021 over them. The Fostex are too bright. The old Denon were good - these are just more unrestrained and fun. The bass gives a subwoofer like effect, soundstage is great for closed back and they have just the right treble pop to contrast against the elevated bass. Mids fit in just right.

They are not at all fatiguing and in fact have a warm tilt to their signature.

Considering they sell for a literal fraction of any of the mentioned headphones - close to like $100 used, I'd consider them a must try for many considering any of those or to buy them on the side to compare. The only thing IMO is they do not scale well with better amplification. They sound great plugged right into a laptop and because they are very efficient, that is how I would recommend.

One other thing - the technicalities strike me as distinctively mid-fi. But again, at $100, you are not going to get technicalities like a Hifiman HE6SE, Focal Clear, or insert other $400+ headphone that costs 4 times as much.

Solid Build, Good Materials, Great Comfort and Budget Friendly Price but, What About the Sound?
Pros: Very Well Built with Quality Materials
Easily Likeable V-Shaped Sound Signature
Pretty Good Sound Stage
Extremely Comfortable
Cons: Too Warm in Other Words Thick Sound Will not Suit to Everyone or Every Music Genre
Not Very Technically Capable
Isolation is Just OK for a Closed Back
Mids are Sucked Out and It Feels Unnatural in Some Songs
Sivga SV021 Robin

SV021 Robin is Sivga’s Closed Back headphone that is targeted toward more budget concious consumers. Their MSRP is 179$ but usually sold at 149$. Sivga recently released Oriole which is sold for 199$. I’m not sure if they are supposed to replace SV021 but for now that doesn’t seem to be the case. Unfortunately, I don’t have Oriole so this review does not consist of the two models’ comparison but if we get a pair in the future, we will try to update this one too.

Disclaimers​

Without boring you too much, I don’t necessarily have a sound preference. I tend to enjoy different sound profiles as long as they do well at what they intend to do. I try to be critic in my reviews but I might be somewhat biased one way or another (Recency bias, buyer’s bias etc.). Please keep these in mind. Also, I bought Sivga SV021 Robin as well as other headphones mentioned here with my own money. If a unit I reviewed is given or loaned to me in the future, I will say so here.

Build, Comfort and Trivia​

SV021 Robin is my second pair of Sivga headphones I owned and reviewed (you can also check out my Sivga Phoenix Review here) and the third I owned if you take Sendy Peacocks into the account. All the Sendy headphones, as far as I know, are planar magnetic. Sivgas on the other hand, mostly dynamic drivers except P-II which is also a planar magnetic Like all the Sivgas, SV021s very well built with wood, leather and metal. Of course, in this case leather is probably synthetic but still earpads and headband is so soft that you don’t want to put them off even if you don’t listen to music. Pads are made from soft memory foam. In the box, they only included 1.6m long single ended cable with fabric coating, 6.35mm jack adapter and a carrying pouch as accessories.

Sound​

SV021 Robins have a V-Shaped sound signature that is not very generic. They are not correct sounding but not very offensive either.

Sivga SV021 Robin

Bass​

Bass is the most prominent part of SV021 Robins’ sound signature. They have decent subbass extension. However, you would expect such quantity would rock your socks off which is not the case. Robins are quite gentle. I had Meze 99 Noirs for a while and I expected these to be similar. I was wrong. SV021 Robins sound warm, even thick but they don’t hit hard. More like they push or try to shove you but there is not much force behind it. Maybe I’m spoiled with better headphones and IEMs but this is how I felt with SV021s’ bass.

Mids​

Bass bleeds into the mids, well it is more than bleed, it invades the mids so you end up with thick sounding headphones. Then it gets sucked out somewhere which causes unevenness in some songs. Modern genres are relatively safe but complex songs suffer from this quite often.

Treble​

Like most of the V-Shaped headphones, SV021 Robins are bright up top. They can get sibilant and grating quite easily in higher volumes. Also, you can come across sudden peaks even when you think you are listening in a relatively safe volume. To be honest I had one the worst Gangsta’s Paradise experiences with their mushy bass and tiring treble.

Technical Performance​

I’m not sure what to say here. I don’t think the drivers are particularly capable, then again, they can also be held back with this kind of tuning. Alhough SV021 Robins sound wider than the usual closed backs, they are not particularly wide. Notes sound like they linger more than necessary, which can be also a good thing if you like it. They are not very resolving but, you may hear some details you haven’t before and you may not hear some details you are familiar with. This aspect can be attributed to bright treble and recessed mids of SV021 Robins’. Their warm nature also hampers the clarity quite noticeably. All in all, they are weird more than they are bad.

Quick Comparisons​

I couldn’t find a fair closed-back rival to compare for SV021 Robins to be honest. My Beyerdynamic Custom One Pros and Dekoni Blues are both modified. So just for comparisons sake I pulled out my Fostex TH610s. They have a warm neutral sound signature which is quite different from SV021 Robins’. But this may also serve as to decide SV021s’ alignment.

Sivga SV021 Robin vs. Fostex TH610​

  • Although both are easily driven, TH610s are harder to drive.
  • Neither isolate sound very well due to their vented structure.
  • Sound quality difference is easily noticeable. TH610 sounds more correct.
  • SV021 much more bassier, warmer and thicker, TH610 more neutral. But TH-610s bass is somehow more satisfying. There is more definition and texture to it. SV021 is kind of mushy.
  • SV021 also has more subbass which is not surprising.
  • Mids are more forward on TH-610. Female vocals sound lovely but borderline shouty at the same time.
  • TH610 is also bright in the upper frequencies and can get sibilant like other Fostex headphones but not as much as SV021.
  • In all technical aspects TH610 is superior, they are clearer, wider, more resolving and separation of instruments is much better. Then again, Sv021 and TH610 are in different price ranges and have different sound signatures.

Conclusion​

Sivga SV021 Robins are decent headphones, or good headphones considering their price. No other closed back headphones come to my mind those are as well built as these. If, at least one of the negatives I mentioned was absent they would be an easy recommendation from me at their price. However, I cannot recommend these to everyone as they are. If you are on a budget, looking for a pair of decent closed back headphones, comfort is very important for you or you are not listening to your music critically I’d recommend these. Otherwise, you need to expend a little more.

Just got mine from Amazon----have had them on for 5 minutes now----all I can say is they are absolutely gorgeous looking and are extremely comfortable so far--light as a feather , the pads are like pillows on the ears, obviously time will tell if this will remain the case but so far these are the most comfortable headphones I have EVER worn-seriously.
Sound----need to be broken in--they are a $ 150 pair of headphones--I would go with the above video review--so far I can tell they are very clean and detailed--no doubt--when they break in I think they will fill in and be really good. So far I am VERY pleased.
I have a balanced cable from a Thieaudio Phantom Planar that fits the jacks so have 2.5 mm balanced all set up----one of the reasons I was not hesitant to buy. The stock 3.5 cable is very good---high quality-----I say this is a very good buy for the price.

Well built--really gorgeous---super light weight--cannot express how comfortable these are--and have full confidence they will break in and sound really good. I love the Phoenix I purchased a few months ago and 10 minutes in I can safely say these are a winner for the price-----I am very happy with these! 😎

After breaking them in all weekend----these are excellent, certainly a bargain in the $ 150 price range. Rich, smooth, clean--COMFORTABLE, well built and really snazzy looking. I say another homerun for Sivga---
Would LOVE to be able to get these earpads for other models--seriously--these are the most comfortable earpards/earphones ever-----
Hard to believe this kind of quality is available for such a low price-(in terms of audiophile dollars).
I will others who are better describe the sound do a in depth review--all I can say that i am very well pleased with the purchase and am enjoying these VERY much--nothing but praise at this price point---satisfied. 😋

It would be worth asking people who already have them. I know @RikudouGoku should have one coming his way very soon.
