SIVGA & Sendy Audio - Official Thread

Review of Sendy Audio Peacock

As always, this review is also available in Spanish on my blog and on YouTube, links at the end of this post.

These headphones have been very kindly sent for review by Keydis, the official distributor for Sendy Audio, along with Sivga, in Spain. Keydis does not sell directly to the public but I have left a link on my blog (and YouTube) that shows the various stores that carry these brands in Spain.

I am very grateful to Keydis for sending these in and, as always, I will leave my opinions in the most honest and unbiased way possible but, as I always say, it is good to consider the fact that it has not cost me anything to try these headphones.

Intro…

Not long ago I reviewed the Phoenix, which is a headphone by Sivga, who are a brand that belongs to the same company, Sendy Audio. While Sivga focuses on more budget orientated models, Sendy Audio is responsible for the higher end models, with the new Peacock being the TOTL planar magnetic headphone which was released quite recently.

It is my first experience with Sendy, however, this headphone is priced similarly to a headphone that is commonly recommended in this price range, the Hifiman Arya, a headphone that I do have quite a bit of experience with. So, although my review will be focused on the Peacock and how it performs in general, I will make a few comparisons to the Arya later in the review.

Presentation…

The headphones arrive in a simple brown box very similar to that of the Phoenix, with contents that are somewhat similar also but with more focus on quality.

Inside the box we find a headphone case that is also very similar to the one supplied with the Phoenix, however, in this case it is of a brown colour, with a gold coloured zipper and hardware, and has the Sendy Audio logo embossed on the top. This case, while mulded to the shape of the headphones, has four feet on the bottom to allow it to stand upright, making it much easier to store.

Inside the case we find the headphones and a drawstring cloth bag. The bag contains the cable that is supplied with the Peacock, a nicely braided two tone cable which ends in a 4.4mm balanced connector. The nice thing is that Sendy also includes two adapter cables, to convert the 4.4mm balanced to either a 4 pin XLR or a 6.35mm TRS, for those who want to use these headphones unbalanced. There is no 3.5mm option but this is to be expected, as these are not really headphones aimed at being used portably.

Build and aesthetics…

Let’s start with the cable. This is an 8 core braided cable, in two tones of brown, with a wooden chin slider and splitter that has Sendy Audio carved on it. The connectors seem to be of good quality, although I am not sure of the brand. The 4.4mm connectors (both male and female) have spring type cable strain relief and in general feel very nice. In fact, I would say that the cable is one of the nicest cables I have received with headphones for quite some time. I also want to say that I am not a fan of proprietary connectors on headphones, or at least ones that are not common, as I like to make my own cables, but the ones used on the Peacock are very nice, they are smooth and easy to connect and remove. I have found that I am quite a fan of them.

Moving on to the headphones… well… they are certainly aimed at looking high quality. I must say that while I love wooden headphones, I am not really one for gold (not just on headphones but in general, I don’t have any bass guitars with gold hardware either) and the cups sport very large gold and black grilles that certainly stand out. However, independently of my personal tastes, I can not say that these headphones do not look and feel like headphones of their price range.

Everything is well matched, well put together, I really can’t see any flaws in either build or aesthetics (again, ignoring my opinion of gold). Everything that should be metal is metal, everything that should be wood is wood, and even the pads feel and look premium (they actually smell of leather, so I am guessing they are real leather, although I may be wrong). The same goes for the headband, which is metal covered in leather and yellow stitching, with a very nicely padded leather comfort strap.

The headphones do have a little weight to them but they are not heavy enough to be uncomfortable, at least I haven’t found them to be tiring on long sessions (and I have certainly had some long sessions with these over the past week). In fact, I find them to be very comfortable in general, with nice openings inside the cups that are plenty large enough for my ears.

Sound…

When I receive a set of headphones for review, the first thing I do is open them and give them a very brief listen before I put them on another rig for burn in. This is usually only for about a minute, just to make sure that they work correctly and then I put them on the burn in rig for around 150 hours (I am not entering the burn in debate, it just doesn’t cost me anything to do it, so I do and avoid discussions while also avoiding brain burn in). When I did the brief listen of the Peacock, which was just with a Modi3 and Atom, I literally had to force myself to take them off about 30 minutes later.

Admittedly, at the time I was listening to the Marshall MID ANC (preparing for the review), so I guess it wasn’t surprising that the switch to these was very positive, but I just vibed with the music and really enjoyed them. I was actually very sorry to put them on the burn in rig and go back to the MID ANC.

During last week, I did listen to them a few times while I was testing the Zen Signature Stack and found them to be very nice on that set up but I refrained from using them too much until I could dedicate myself to them this week. Now, if you saw my review last week, you know that I finished the week listening to various Hifiman headphones, one of which being my favourite headphones, so normally anything would have been a bit of a let down after those, which is why I usually reset by listening to something else for a couple of days in between. In this case, I just went straight to the Peacock and can’t say that I felt let down but it wasn’t quite as perfect as my first listen may have led me to believe.

Starting with the subbass, as always, these are certainly not a sub bass heavy set of headphones. There is some roll off and I found that the iFi Zen CAN Signature HFM was a very good match for this, giving a little boost in the lowest regions (although the 2kHz boost that came with it wasn’t as much of an improvement as on other sets). This small boost in the lowest regions could be obtained with some very simple equalization but, as you probably know my tastes by now, I really don’t think it needs it because the music that these headphones make me want to listen to really doesn’t have much in the way of subbass anyway.

Moving on to the remaining mid and higher bass frequencies, here the bass is much more balanced and has a very nice warm and rounded sound to it. I have enjoyed listening to lots of blues, rock, simple electric guitar and bass tracks and, of course, my usual acoustic selections. I find the timbre of the bass to be very pleasant and smooth. There is plenty of detail in these lower regions but I don’t find it to have the dryness that I find on other planar offerings, such as the Ananda for example.

To give some examples from my usual test playlist, I basically enjoyed anything with a natural low end, from “No Ordinary Love” by Sade, “Crazy” by Daniela Andrade or “Diamonds on the Soles of Her Shoes” by Paul Simon, all sounded great to my ears. Other tracks that were more focused on electronic bass, such as “Sun is Shining” or “No Sanctuary Here” didn’t sound bad but didn’t seem to bring out the natural flavour that these headphones exhibit in these lower ranges. The Peacock doesn’t really inspire me to listen to EDM or even Hip-Hop, although it certainly doesn’t do a bad job of it.

In the transition to the mids, I did find that on some songs there was something that sometimes stood out as strange. I couldn’t quite put my finger on what it was, just on a couple of tracks I found that the bass sort of disconnected from the midrange. Now, this was something that was so slight and so ocasional that I wasn’t sure if I was imagining it or if it was really happening. I noticed it on parts of “Killing in the Name” (although not throughout the whole track) and also in “Hotel California” by the Eagles (the acoustic version), along with a few others.

In the end I cheated and looked for measurements online (usually I don’t look at measurements until after I have listened and come to conclusions) to see if I really was hearing something or if I was just making it up. I found that (according to a couple of graphs) there is a little bit of a dip followed by a slight rise between the 500 to 1000Hz range. It is only slight and I really don’t think it is enough to be noticeable on 99% of the tracks I have listened to (I have listened to a lot of music on the Peacock) but obviously just sometimes coincides with certain frequencies in recordings and makes it seem more apparent. I really don’t think I would have ever been able to find it if it wasn’t for the graphs, in fact, it really isn’t even in the transition between ranges, it is just after the transition, but I thought I would mention it (especially after looking at graphs to make sure I wasn’t going crazy).

In general, the midrange is very nice. It is the sort of midrange that manages to provide plenty of detail while seeming relaxed, not throwing the detail at you. Voices sound rich and smooth, giving them a very intimate feel without feeling close like they do on something like the HD6XX. Voices such as Zella Day in her version of “Seven Nation Army” manage to be present without being overpowering or harsh.

However, moving up towards the top end of the mids and into the treble, here is where I find these headphones differ from what I am used to in planar magnetics. There is the usual dip found around 2kHz that is inherent to the Hifiman line up, however, the following frequencies don’t return quite like they do on said headphones. Rather than 3kHz being higher than the lower and middle of the midrange, the Peacock do not bounce back in the same way. In fact, the frequency response of the higher ranges is at a lower level than the mids all the way up to the highest of ranges.

In fact, the treble range is a little strange, it sort of seems like it is rolling off but in a bit of an intermittent way. This can cause the treble range to sound a little blunt but with certain frequencies cutting through on occasions that are not expected. The positive side to this is that the Peacock does avoid sibilance and harshness in its majority, except for those frequencies that seem to appear on occasions and are sort of unexpected.

I can’t say that I hate the treble, it is not quite as clear as I would like it to be but at the same time does help these to be a bit more of a relaxed listen than other options. I do feel that some EQ could go a long way with these headphones however.

As far as soundstage, it’s also sort of midway. It is not huge and open like on something like the Arya but it does not ever seem to be too closed in either. The image placement is very good, “Bubbles” is very 3D like, but it does it in a way that still feels close though not claustrophobic. For example “Letter”, also by Yosi Horikawa, has great movement but does not really go wide off to the left or right.

Comparison to the Hifiman Arya…

First let me say that these are the Arya 2020 version, not the new Arya with the Stealth Magnets (I will be reviewing those soon but have not yet heard them). If you want to know what I think about the Arya, then you can see my full review of them here. I also want to point out that this is comparing them side by side on the Asgard 3, not on the Zen CAN HFM, which I feel improves the Arya with the HFM+XSpace engaged.

I moved over to the Arya after about 3 hours of constant listening to the Peacock, so obviously things jumped out at me straight away, probably in a more exaggerated fashion at first.

I must point out that, to be at similar listening levels, I kept the same level on the dial of the Asgard and just flipped it to high gain when moving from the Peacock to the Arya (and vice versa), meaning that the Peacock does need less power.

The first thing that struck me straight away was the open soundstage of the Arya. Now, I have mentioned on many occasions that the Arya can sometimes be too open for my preferences, making things sound too far away. However, that is also a very impressive sensation when you first listen to the Arya and coming to them from the Peacock was no exception, the soundstage is huge and does make the Peacock seem very intimate in comparison. I am not saying this as a bad thing, I really like a closer sound on many occasions, but it is certainly something to consider if you are contemplating between these two headphones.

The next thing which is obvious is the treble of the Arya, being more elevated, making for a brighter sound signature but without losing that power of the bass that the Arya can portray when needed. But at the same time, the lower end of the Phoenix is far warmer, even if it is not more elevated in those frequencies than the Arya. It is the reduction in the higher ranges that makes the low end more noticeable on the Peacock.

For example, listening to “Give Me One Reason” by Tracy Chapman on both headphones, it is as though the guitar is being played through two completely different amplifiers/cabs. On the Arya it comes across as a rather clean guitar tone, while on the Peacock it comes across as a much warmer tone, as though it is being played through a warm tube amp (if that makes any sense to you non-guitarists, or even to the guitarists out there). Her vocals are pleasant on both headphones, however, the Arya does seem to bring them further forwards.

In fact, the comparison of amps I just made is quite relevant to these two headphones in general. As a bassist, and a lover of both clean tones and warm tubey tones, I would say that the Arya is the clean rig while the Peacock is the warm tube rig. Which one anyone will prefer will depend on their personal tastes.

Conclusion…

I really like the Peacock but I like it for reasons that are not usually my main focus when listening to, or chosing, headphones. The Peacock brings a warm and relaxed presentation, which I have found very enjoyable for long listening sessions, especially for a lot of my acoustic and also blues genres.

There is plenty of detail, however, that treble range does make the detail take a bit of a back seat behind the lushness of the lower end. It is certainly something that I have found more enjoyable for a relaxed session rather than a “focus on detail” session.

These are a set of very well built headphones, they look good (if you are into wood and gold) and they perform very well in comparison to so many other headphones. They include accessories that I wish other companies would take note of, especially in the cable department, and are quite easily powered for such a large set of planars (although the answer is no, I don’t suggest connecting them to a smartphone).

The question of whether these are for you or not will depend far more on your taste in sound signature than anything else. If you want a relaxed, warm set of planar magnetics, then the Peacock should certainly be on your list to try. If you are more of a clean and extremely detailed person, then maybe you might prefer some other options.

I always try to avoid reading or watching reviews if I am going to review something, so I avoided reading your review until now. Yours makes much more sense :smiley:

We are not 100% in agreement about everything but yours at least explains some of the stuff I have been experiencing in a more coherent way!

The Sendy Peacock is a disaster.

I’m on my way, should I bring beer or coffee?

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.

Keydis do not sell directly to the public but you can find the Robin via the following stores in Spain: https://www.keydis.es/comprarsivga.html

Intro

Let me start by being totally honest, I did not think I was going to like the Sivga Robin. These are not a set of headphones that I know nothing about, in fact, I have read many reviews and seen plenty of graphs of them, which all led me to believe that I would not be a fan of them. However, even though this is a bit of a spoiler, I have actually found that I do enjoy them, even if they are exactly as I expected them to be.

Now, it is not that I had heard bad things about them, just that the descriptions and graphs pointed me to a set of headphones that doesn’t really align with my personal preferences. I will get into more details as we go through the usual review steps.

In case anyone has not come across Sivga before, they are the more budget oriented brand of Sendy Audio, a company that has released some very interesting headphones. I have reviewed another model by Sivga in the past, the Phoenix (full review here) and also a set from their more premium line, the Sendy Audio Peacock (full review here). Both of those headphones are sets that provide a very premium look to them, sith the use of leather and wood, something that the Robin also has.

But I am getting ahead of myself, so let’s get on with the review.

Presentation…

The presentation of the Robin is nothing special. A black box with a sketch of the product on the cover opens to reveal the headphones, a 3.5mm TRS to dual 2.5mm TS cable, a 3.5mm to 6.35mm adapter and a cloth bag.

This is not a huge amount of content, nor is it really a premium presentation, but it is enough to make the headphones usable straight from the box and, let’s face it, for a set of headphones that retails for less than 170€, I really can’t bring myself to complain. As always, I prefer the money to be spent on the headphones rather than the packaging.

Build and aesthetics…

As with other models, Sivga opts for a build using wooden cups and (faux) leather covered headband and pads.

The Robin is also available in a lighter wood and leather finish, however, the version I have received is a dark stained wood (which is not actually as dark as online photos would suggest) and black leather. The yokes and headband are metal, finished in a dark gunmetal grey, which work well to give the headphones an overall look that I feel suggests a higher price than they actually sit at.

There is a little creaking when moving the headband around, nothing terrible but it is noticeable, and unfortunately there is no swivel in the cups, something that may be a deal breaker for some, but is actually fairly well counteracted by the pads.

The headphone pads are the softest and most comfortable pads I have ever come across on a set of headphones. They really are soft and squidgy, to the point where I keep getting people to feel them. This means that the seal is good, even without any cup swivel, but it also means that comfort is excellent. Even straight out of the box, putting these on my head felt like I had been wearing them forever, in a good way! It’s like an old pair of slippers that are just perfect.

In general, any complaints I may have had about (minor) build issues, is outweighed by the aesthetics and comfort. These really are a pleasure to wear.

Sound…

As I said at the start, I was certain that I wasn’t going to like these, based on the graphs and the descriptions by other reviewers. The strange thing is that, while they sound like I expected them to, I don’t dislike them, in fact, I find that they make me feel very relaxed as soon as I put them on.

The subbass extension of the Robin is good but it is not exaggerated. There is no sign of roll off on any of my usual test tracks but there isn’t any boost either, well, at least in comparison to the lower end of the midbass. These headphones do have quite a boosted low end overall, which starts to drop off around the 200Hz mark as they make their way to the lower mids.

Tracks like “Way Down Deep”, have a deep and full bass, with some strikes that may be a little overpowering, at least for my personal tastes, but I can see this bass being impressive for a lot of people I know who like bass centric tunings. Something a little more pop orientated, like “Get Lucky”, still has that extra bass going on but somehow manages to keep it from taking over the whole sound.

This elevated low end does give the headphones quite a bit of warmth but as they drop down moving into the lower mids, it doesn’t seem to become overly bloated and undefined. The bass is not quite as clear as I would like, especially as I mainly listen to planar-magnetic headphones lately, but it doesn’t irritate me. Sometimes, when I listen to headphones with this kind of low end, I find that everything seems slow and sluggish (even if it is not the case), but the Robin don’t really leave me with that sensation.

The lower mids are fairly recessed, but do start to climb back up by the 600Hz mark, levelling out between 1kHz to 4kHz, although at a lower level than the bass areas. This means that vocals are present but they are not forward. In fact, there is a general smoothness to vocals except for a peak that follows (somewhere around 5kHz) that can make certain vocals sound a little “honky”.

My usual acoustic instrument orientated music selection actually comes across quite nicely, while not something I would consider to be tonally correct, it has a nice rounded and relaxed presentation to it. For example, “Hotel California (Live on MTV)”, is presented with fairly clean and articulate guitars, even if a little warm. The percussive hits during the intro are a little overly boomy when they start on their own, but balanced with the rest of the instruments, they no longer hog the spotlight.

Moving into the higher ranges, the extension is good but it again comes across as smooth, without seeming to be very airy or spacious. The vocals on “Hallelujah” by The Pentatonix, are sometimes surrounded a little too much by the backing vocals but I have found that I don’t hate the result. This something that does happen depending on the vocals, another example would be “These Bones”, where the deeper vocals take over the space.

There are a few occasions when there is a little too much “bite” depending on the frequencies, which can find me reaching to turn down the volume on ocasiones but to be totally honest, these headphones have tended to make me raise the volume a little more than usual. At my normal listening levels, the odd peak does not seem to appear except on very specific songs.

The soundstage is also rather small. It’s not terrible, remember that these are closed back headphones, but it is not extremely wide either. The overall presentation of images and layers is decent but not amazing. At the risk of repeating myself again, it’s all rather smooth.

Conclusion…

The Sivga Robin are a set of headphones that I would consider a guilty pleasure for myself. They sound just like I would have expected them to sound, based on graphs and reviews. To use words that make no sense, I would say that they are “creamy with a little bit of spice”.

The bass is far more elevated than I would like, the recession in the lower mids is something that I would not choose, and the peak around the 5k mark is something that I would avoid.

Yet I like them.

There is something about that creamy smooth sound, with those extra soft pads, that just causes me to relax when I put them on my head. They are certainly not a set of headphones that I would choose to evaluate music, nor to focus on details and layering and all those things that I usually enjoy from headphones, they are just a set to put on, put my feet up and zone out.

I have said many times that I am not someone who enjoys overly present bass,nor extra warm sound signatures, and these are basically everything that I would say I don’t enjoy, but I do.

The whole set up, from build to comfort to sound can be collected in one word, smooth (maybe except for those peaks that can appear in the upper ranges at times). Even the “honky” sound in the upper mids/lower treble is not something that detracts from the overall package.

I really can’t find a way to explain to myself, nevermind to all of you, why I like these headphones. Sometimes we just like what we like and we should stop spending time to justify it.

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.

As always, this review can also be found in Spanish both on my blog (here) and on YouTube (here)

Nice review as usual.
They’re a handsome little set… I really like the looks of them. If they were more readily available they would be worth trying out at the price. Maybe in the future :man_shrugging:t2:

A little late to the game on these but my wife surprised me with a pair for my birthday in April. I actually quite love them… for Hip Hop. Not really much else (I’ve mostly been listening to Jazz and Hip Hop these days).

Initially, they sounded “boxy” but after a few days, I’m not sure what changed, but the boxy sound was gone and everything seemed to mellow out. I’m not necessarily a subscriber to “burning in” headphones, but in this case, the sound definitely seemed to get better after a few days of listening. I still prefer my Sundara’s and Clear’s for most music, but for Hip Hop/Hip Hop adjacent music, these seem to hit a sweet spot for me.

Heard a bunch of Sendy/Sivga headphones at a recent audio show. Only thing that impressed me at first listening was Sendy Apollo, a comfortable, warm sounding planar. Will try to hear it again, if I get the opportunity.

Coming back to this after having used them for a a while now… They’ve actually become the headphones that I reach for more often than any of my others (Clear OG, Sundara, Elegia, DT 700 & 900 Pro X). Not really sure what’s changed since my last post, but now, even Jazz sounds amazing on them.

Here I was initially believing I was gonna sell them… Now I’m thinking maybe I favor the darker/warmer sound of these compared to my others. I’m also considering selling my others (not the Beyer’s, as I use those for recording, mixing and mastering) and buying the ZMF Aeolus (I’ve had my eye on them for a while now) as my DD headphone. Not quite sure I’m actually ready to let go of my Clear OG yet, tho.

Decisions, decisions…

While this is not an IEM thread, I thought it would probably be the best place for this review…

Sivga Nightingale


TLDR version on YouTube: TDLR - Sivga Nightingale

The Nightingale have been sent to me directly by Sivga for me to share my impressions and thoughts in this review. They have not made any specific requests and I will do my best to be as sincere and unbiased as humanly possible.

You can find the official Sivga page for the Nightingale here: Welcome to Sivga !

As always, this is a non-affiliate link, meaning I do not receive anything in exchange for clicks or purchases made.

To avoid being repetetive in my reviews, you can find all the info about how I create the reviews, equipment used, how I receive the products and how to interpret my reviews by visiting: About my reviews


Intro…

This is the first set of Sivga IEMs that I have tried. They do have a few other models but these are their latest release, and feature a 14.5mm Planar driver, which I believe is their first entry into the planar IEM world.

I am not overly sure what the street price of these IEMs is but the links they share on their official page (at the time of putting this review together) lead to them being available on Amazon US for $230 and on Aliexpress for 333€ plus 87€ shipping. So we are not talking about a budget set of IEMs here.

Having reviewed some of their headphones in the past, I know that Sivga are capable of some good stuff, usually with their own twist to it. In this case, they certainly put their own twist to but let’s start from the beginning.


Presentation…

The packaging is simple but elegant. Arriving in a black box with just the brand and model on the front, along with some brief details on the back, the lid lifts off to reveal the IEMs sitting in a cutout with the storage case sitting in another cutout below. There is a velvety finish to the surrounding material that helps with the elegance.

Opening the storage case, which I am quite fond of, we find the included 4.4mm cable, along with a plastic storage case for the additional 6 sets of tips that are included. The tips are 3 sizes of 2 different types (plus the ones installed) but I will say that they are a little on the small size. The largest size work fine for me personally but I am usually a medium (depending on tip type and IEM in question), so if you are someone with larger canals, you will need to provide tips that work better for you.

The plastic storage case for the tips is a nice touch. I do have a few of these around but this one is a little more compact and fits easily in the mesh pocket of the included transport/storage case. Speaking of the case, it is semi-rigid, more towards rigid than semi, and has a black and grey pattern to it with the Sivga logo on the top. The case is of a nice size and of good quality. I don’t usually go into this much detail with included cases, so it shows that I am a fan of this one.


Build and aesthetics…

The Nightingale use a teardrop shape for the shells, with a resin interior shell and a faceplate with a wood look to it that is surrounded by a metal border. The IEMs are fairly small and, although they are not the lightest of IEMs for their size, they fit me well and caused no fatigue over longer listening sessions due to the build.

The two pin sockets are sort of recessed behind the faceplate, just slightly, which gives for a very accomplished aesthetic when they are connected. The included cable is pretty decent, with metal hardware except for the strain relief around the two pin connectors, which is black rubber but has a silver metal ring that matches the aesthetics of the IEMs.

I have to say that I am quite fond of the simple but elegant aesthetics of the IEMs and have no issues with the fit or the apparent build quality.


Sound…

I’m afraid here is where things go downhill. When listening to the Nightingale out of the box, I had flashbacks of the Audeze iSine IEMs. I’m afraid that the tuning of the Nightingale is possibly one of the worst I have come across on planar IEMs out of the box, along with the iSine.

There is a lack of bass to the tuning that is very apparent. I have said many times that I am not someone who craves excessive midbass, in fact, it gives me a headache if it is both excessive and not of great quality, however, the Nightingale is more that just lean on the bass, it is pretty absent. Even with smaller bore tips, I still found it to be way below my preferences.

But the lack of bass I can live with, a quick press of a button on an iFi device makes things much better, it is the upper mids that I find the worst on these IEMs. At 1.5kHz the tuning just rolls off and keeps rolling off until it appears back with a peak well into the treble range. This makes everything sound unclear, distant, and, well, just bad in my opinion.

I know that audio is very subjective and I am always the first to preface things with “in my opinon”, “for my tastes” or “with my preferences”, and I am sure that someone will enjoy the Nightingale tuning out of the box, but I think that will be a very small selection of people.

Just so you know what I am talking about, here is the graph in comparison to my usual personal target as reference:


Honestly, it looks as though they had the graph upside down when tuning these IEMs!

Usually I go through a detailed listening session with my list of test tracks (which can be found here) and mention things that I notice, always referring to the same tracks so that it is easy to compare with any of my previous reviews. However, in this case, it just isn’t needed, as the things that grab my attention are all negative and I have already explained the overall picture above.

But let’s get away from the negativity and talk about fixing the issues!

I mentioned the Audeze iSine above and, for those of you that don’t know, it was one of the main planar offerings way before the planar boom that happened recently. I think that it was generally agreed (obviously with some exceptions as always) that it was tuned pretty terrible and needed EQ. In fact, even the manufacturer knew this and sold a specific cable with DSP inside that did the EQ and made it a pretty darn good set of IEMs, holding up to even the recent batch quite a few years later.

Well, Sivga have a set of planar IEMs that are in many ways very similar.

After spending some hours with the stock tuning, I gave up and broke out the parametric EQ, something that I very rarely do for reviews. I will sometimes play around with EQ and do some tests but I avoid using it for detailed listening sessions for reviews. Well, after some tweaking, especially in those lows and in the upper mids, the Nightingale started to come alive. In fact, it started to be a very enjoyable and good performing IEM.

After some more playing around, I started to investigate tuning it to some other FR’s from other IEMs and I have to say that I am very impressed with how well this IEM performs when we take it towards other tunings.

Obviously it is great when tuned to my preference target but when tuned to other IEMs that I am fond of, it took very well to their sound signature and performed on a very good level. It was a lot of fun to take tunings that I like from budget IEMs and turn the Nightingale into a set that had that same tuning but with much better performance.

Even when I pushed its limits with some ridiculously bass heavy tunings, the Nightingale didn’t seem to suffer (as long as the preamp was set correctly of course) and outperformed a lot of IEMs at their own game.

It is capable of good detail, good sound stage, good image placement, in fact, it is just a very capable IEM in the sound department, it just needs tuning.


Conclusion…

I never enjoy posting negative reviews and, to be honest, I don’t feel this is a negative review in general, the only negative about this set is the tuning.

I don’t score IEMs except on Head-Fi as it is obligatory, but in this case, a set of 3 out of 10 IEMs could easily become a 9 out of 10 just with some EQ applied.

Now, I understand that there are a lot of people out there that don’t want to EQ, and plenty of people out there that really don’t understand EQ or how to use it, but I do feel that, with the Nightingale, it is going to become an obligatory part of the chain.

The bass can easily be fixed with a bass boost on an iFi chain, or even by using an impedance adapter. In fact, there may be plenty of people out there who are ok with the bass, even I could live with it for a lot of music, but it is that huge absence in the 2 to 8kHz range that makes me say that EQ is a must with these IEMs.

They are a well built, comfortable and good looking set of IEMs that, when EQ’d, become a very good set of planar IEMs, rivaling almost all the other planar sets out there on performance, but they need that tweak to get them there.


As always, this review is available in Spanish both on my blog (www.achoreviews.com) and on YouTube (www.youtube.com/achoreviews)
