Luan โ forename of many a footballer, at least three fictional characters, a Chinese county and river, and a constructional plywood used in flooring. Here, however, the name refers to the Chinese mythological bird. Red in colour with 5 distinct markings, shaped like a chicken with a song in the standard five pitches, appearing when hymns of praise are sung to rulers, accompanied by the dancing Feng. A sighting of the Luan indicates an omen of peace. The Luan is the latest headphone model by Sivga to be named in reference to a bird โ first the Robin, then the Oriole, and now the Luan.
But where the Robin and Oriole were broadly similar, the Luan is a significant departure in design. It is an open-backed design with 50 mm dynamic drivers, plush padding and exquisitely machined components.
The wooden enclosures Sivga are known for are a standout part of the design in either black or mahogany brown. They are CNC machined and sanded, lacquered and polished by hand to a flawless finish. The almost seamless joints between the wood enclosures and the rear grille frames are a testament to the attention to detail that goes into manufacturing these headphones, which is even more remarkable when you consider their price point of only CA$ 449 (US$ 359, ยฃ299).
The value doesnโt stop there, either. The packaging is a smart black box with a lid that lifts off slowly to reveal a full-size hard shell carrying case. It looks a lot like the case of the Sendy Aiva but finished in a smoother, more supple leather. A drawstring hemp cloth bag contains the accessories, a 1.6 mm headphone cable and a 1/8 inch (3.5 mm) to quarter inch (6.3 mm) adapter.
The cable length is my only gripe. I wish a 3 metre cable were included. Though fine for desktop use, the included cable is too short to relax in a chair set back from your headphone amp. I enquired about this and Sivga do sell a longer cable, but donโt include it over concerns the added length may affect the sound quality. Apparently few people buy the cable as an accessory, though as it is not a widely advertised option, I canโt say Iโm surprised. Fortunately, the cable connects to 3.5 mm jacks on each ear cup, so you can use any standard cable of your choice, including a balanced cable if that is your preference.
On the plus side, however, the padding is exquisite. The ear pads are made of protein leather and memory foam, and faced with a soft velvet. Theyโre a conical ovoid shape that encircles the ear and provides a good acoustic seal, with perfect clamping pressure from the steel headband. They are extremely comfortableโmore so perhaps than the Aiva. They weigh 354 grams but you wouldnโt know it.
They use a suspension headbandย design whereby the ear cups themselves are fixed to the frame, and the suspension band across the top adjusts to provide support across the top of your head. Thereโs hardly any pressure on the top of the head and just the right amount to the sides, applied by two spring-steel bands forming the arches at the top of the band. I could wear them all day.
The open-backed design will take some getting used to if youโve never experienced it before. The rear of each ear cup housing has a mesh grille for protection, but that grille is (mostly) acoustically transparent. The result is that the driver operates effectively in open air with no physical barrier besides the barrier of the front and rear grilles and the driver itself. The shape of the ear pad forms an enclosed chamber around your ear so some external noise is blocked, but a good open-backed design almost lets you hear โthroughโ the driver, so to speak.
This means you can hear whatโs around you, and the headphones do leak sound more than a closed-back or semi-closed design so everyone else in the immediate vicinity can hear what youโre listening to. This isnโt a problem for private listening, though using them in an office or a family room will probably raise complaints, depending on your musical taste.
The advantages, however, besides increased situational awareness, is an improved stereo image. Just like when you listen with a pair of loudspeakers, the room and the reflections within it play a part in the sound you hear. Itโs a bit like listening to a pair of nearfield loudspeakers, but with holographic imaging and the obvious awareness of the headphones clamped to your head.
The driver diaphragm comprises a nickel-coated carbon-fibre composite dome which dissipates and suppresses excessive vibration effectively, and is lightweight and rigid with a highly elastic driver surround. It is driven by a copper clad aluminium coil and a 24.5mm, 350KJ/M rare earth Neodymium magnetย
Quoted specs are 100 dB +/- 3dB sensitivity, 38ฮฉ +/-15% impedance and a 20Hz โ 40kHz frequency response, with no reference measurements or roll-off given in the spec. I was provided the below graph to illustrate the frequency response.
There is a significant dip at 1kHz and some boosting in the bass and the highs. These arenโt going to give you the low-end impact of the Audio-Technica ATH-M70, nor the awful โhead stuck in a plastic bucketโ impression of Sennheiserโs HD598s. The vibe is chill as the kids would say. Itโs a soft sound with a slight lower mid emphasis. Iโll take this over a high-bass emphasis as the Luanโs colour gives it a warmer tone, whereas high-bass (500Hz to 1kHz or so) grates after a while. So while they wonโt score marks for neutrality, they land high on the pleasant scale.
The mids are the standout quality by far. Vocals are expressive and highly nuanced, aided by excellent imaging. Other reviewers have noted the lack of a โhuge sound stageโ as being a disadvantage. But what the Luan donโt do is create a false image using enclosure trickery. To my ear, the stereo image is one of their strongest suits and is dictated by the source material, and to extent the quality of the amplification.
The Luan are easy to drive. Your smartphone or laptop will have no trouble driving them to uncomfortable levels. Their character doesnโt change when you provide them some real power with a dedicated amp, in this case my reference Topping A90D. But you get more. More โoomfโ in the bass, a cleaner presentation all the way through the midband, and better top-end extension with more stable imaging and more accurate detail. They lap up that power too, never seeming to struggle with the extra juice.
Speaking of the top end, thereโs a bit of a high-end boost for extra snap which slightly emphasises cymbal strikes and decay, vocal rasp, and the nuances of strings. If the Luan were ruler flat through the bass and into the midband this would probably lend itself to excessive brightness and ultimately fatigue. But in reality the blend is pleasing to the ear, and โjust rightโ, giving the sound a bit of added sparkle without being overbearing.
The Sivga Luan is an attractive package if youโre seeking open-backed headphones that offer a pleasant if not strictly neutral listening experience. Beautifully built and generously accessorised out of the box, you get a heck of a lot for your money. Theyโll delight listeners who find Audio-Technica and Beyerdynamic a bit too clinical, but who, like me, canโt stand the closed, muffled, boxy sound that seems to have become the signature of Sennheiser and AKG, among others, in recent years. These are not for bass junkies, and theyโre not advised for use in public or in communal environments. But if you seek exquisite build quality, a thoroughly enjoyable listening experience, and maximum value for money, youโll find all three here. The Sivga Luan earn my unreserved recommendation. Keep โem coming, Sivga.
