Sivga Phoenix Review – The Charmer

Pros –

Excellent bass weight and extension, Clear and natural vocals, Rich and lush presentation, Good soundstage expansion and layering, Gorgeous build and design, Great carrying case

Cons –

Separation suffers from its fullness, Average technical performance in-class, Reasonably limited range of headband adjustment, Thin earpads can affect long-term comfort

Verdict –

Though its unique combination of qualities and thoughtful execution, the Phoenix is able to carve out a reasonably uncontested niche in the audio market for bass lovers who still value clear vocals and a spacious soundstage.


Introduction –

SIVGA are a Chinese audio company founded in 2016 who focus on stunning wooden designs and competitive pricing. They work hand-in-hand with Sendy Audio, their premium division, who recently achieved renown for their well-received Aiva planar magnetic headphone. The Phoenix is their latest creation, an open-back over-ear headphone featuring a huge 50mm dynamic driver. Signature to Sivga, the Phoenix features a premium bill of materials with special mention going to its gorgeous zebra wood cups. Sivga promise a rich and natural sound from its custom dynamic driver with moderate pricing placing it in direct comparison to some of the most acclaimed planar magnetic options on the market such as the Hifiman Sundara. Still, this is a unique approach and one that does feel well executed to boot.

The Phoenix sits just below the planar P-II in Sivga’s line-up at $299 USD. You can read all about it and treat yourself to a set on Sivga’s website. See also Sendy’s website for their premium planar offerings here.

I would like to thank Collin from Sivga and Mark from Capisco Ltd very much for their quick communication and for providing me with the Phoenix and Upgrade Pads for the purpose of review. All words are my own and there is no monetary incentive for a positive review. Despite receiving the headphones free of cost, I will attempt to be as objective as possible in my evaluation.

Specifications –

  • Driver: 50mm Dynamic Driver
  • Impedance: 32 ohms
  • Sensitivity: 103dB
  • Frequency Response: 20 Hz – 20 kHz
  • Weight: 296g

Behind the Design –

Special Film

The Phoenix’s dynamic driver features a uniquely developed polycarbonate film and independently developed diaphragm structure. The company specifies a clear focus on rigidity in order to reduce modal breakup at high frequencies. Meanwhile, a lightweight construction with copper-clad aluminium voice coil promise an agile transient response for a detailed, extended and low-distortion sound. This is enhanced by the adoption of a 3mm thick rubidium iron boron magnet that provides strong driver control and low-end drive. A 32-ohm impedance makes the Phoenix easy to drive.

Unboxing –

Sivga create a premium unboxing experience for the Phoenix with a gorgeous wood-grain and carbon-fibre textured hard box that slides open to reveal a zippered hard case. The case is excellent, moulded specifically for the Phoenix to provide a perfect, extra-secure fit during storage. It has a faux-leather texture and feels very well-constructed, four feet on its base enable the case to stand upright as well. Inside are the headphones and cable within a drawstring hessian pouch. Sivga also provide a 1/4″ adaptor for use with desktop amplifiers. Altogether, a well-considered and high-quality experience!

Design –

Immediately, it’s hard not to appreciate the gorgeous painted stainless steel and zebra wood build that stands out as a defining feature of this headphone. The Phoenix appears premium in materials and provides a timeless retro aesthetic with adjacent chrome and woodgrain drawing the eye. The metal hangers and headband are reasonably lightweight but feel sturdy in the hand, reinforced by well-weighted and smoothly articulating hinges. Due to its compact dimensions, the Phoenix also is far from a heavy headphone at just under 300g despite its construction mostly employing robust metal parts.

This experience is complemented by a slide-to-adjust suspension headband with a wide, padded goat leather strap. It feels super soft and, being authentic leather, should also hold up better over time than faux so long as it is appropriately maintained. The pads are super soft with memory foam interior that conforms well to the individual’s head shape. The sides are pleather, and the face made from a soft suede that provides a comfortable and slightly more breathable experience.

The cable attaches via 2.5mm mono plugs which is a less popular choice these days but still commonly available on aftermarket cables. Unfortunately, I am not so enthusiastic about the Phoenix’s stock cable which is thin and flimsy, barely thick enough to be an IEM cable. Albeit, the cable is very light and unobtrusive, it is also very compliant and doesn’t irk during listening. The connectors are metal and terminations have a nice strain-relief, the 3.5mm plug, in particular, employing a robust spring loaded one. Still, the thinness is a concern for longevity to me, I would like to have seen a more robust cable that better complements the build of the headphones themselves.

Fit & Isolation –

Looking over the design, I was expecting a very comfortable fit, however, the Phoenix’s compact dimensions means there are some concessions for all-day at-home listening. The headband has fairly limited adjustment relative to most competitors. I personally felt I required slightly more length as I was just able to fit the headphones with the setting maxed out. Otherwise, the headband is comfortable and didn’t form any hotspots for me over time. Though do keep in mind, that If you find yourself maxing out the slider on most headphones, the Phoenix may not fit.

In addition, while the earpads are soft and compliant, they are also very shallow. The opening is large enough to engulf my ears by a hair, however, the lack of width means the drivers are constantly pressed against them, causing soreness after an hour or two of listening. The discomfort was mild and I was able to listen for longer, though the Phoenix does feel more to me like a portable headphone than a full-size open-back as a result. The lightweight build and slim pads to me seem contradictory for an open-back design that is not ideal for portable use, and yet it almost appears geared towards it.

This may be the intention of the design as it does isolate considerably more than most open-back headphones, albeit not nearly to the extent of a closed-back model yet alone the stronger ANC performers out there around this price. This does mean they do in a pinch for basic commute. Still, they do leak sound which is not ideal for public transport. I feel the pad design is intentional to deliver the best sound, that said.

Upgrade Pads

For those concerned about the earpads, Sivga do offer OEM protein leather replacements that offer an additional half-centimetre of width for only $15. The pads are held in place by a twist lock like most competitors making pad swapping easy – though of note, they do rotate clockwise rather than anticlockwise to disengage so take care to twist in the right direction during removal. The company was kind enough to send over a pair for evaluation. Though they aren’t as breathable as the stock pads with an entirely faux leather construction without the velour of the stock pads, but do successfully provide more of an over-ear fit. For my ears, they were noticeably more comfortable for longer listening sessions as they reduced contact between the driver and my ears. I think this is a fine option and a reasonably priced extra, though do note that they will change the sound quite noticeably as I will touch on in the sound analysis below.

Audeze LCD-1 Review – Mindfulness

Pros –

Lightweight and comfortable, Folding design, Super soft lambskin leather, Superb balance and linearity, Strong fine detail retrieval in class, Cable orientation always correct

Cons –

Less bass extension than some competitors, Not the most spacious or open sounding headphone, Unorthodox cable design, Plastic build scratches easily

Verdict –

The LCD-1 provides a balance of qualities and conveniences unmatched by immediate competitors.


Introduction –

Who hasn’t heard of Audeze? The US-based headphone manufacturer are an icon of the headphone industry, their LCD line-up having both huge success and staying power. If there’s one thing that alienated buyers from these models, it’s likely their price followed quickly by their large, heavy design. The new LCD-1 is their solution to these qualms, and their sleekest LCD headphone yet excluding the on-ear SINE. It implements the same technologies in a compact form factor designed for all-day comfort. Furthermore, the sound signature has been tuned with monitoring in-mind, pivotal as such a balanced sound is not so easy to come by around this price range.

The LCD-1 retails for $399 USD. You can read all about the LCD-1 alongside Audeze’s technologies here and treat yourself to one here.

I would like to thank Ari very much for getting me in contact with Audeze and making this review of the LCD-1 happen. All words are my own and there is no monetary incentive for a positive review. Despite receiving the headphones free of cost, I will attempt to be as objective as possible in my evaluation.

Specifications –

  • Style: Over-ear, open-circumaural
  • Transducer type: Planar magnetic
  • Maximum SPL: >120dB
  • Frequency response: 10Hz – 50kHz
  • THD: <0.1% @ 100dB
  • Impedance: 16 ohms
  • Sensitivity: 99 dB/1mW
  • Weight: 250g

The Pitch –

Fazor Waveguide

Audeze implement waveguides to avoid unwanted resonances and destructive interference. This enables greater high-frequency extension and resolution in addition to increasing efficiency. Audeze also promise greater phase coherence resulting in better resolution and sharper imaging. Furthermore, the waveguides can help reduce turbulence and enhance damping enabling higher driver control and a more agile transient response. You can read Audeze’s description here.

Fluxor Magnets

Audeze headphones utilize very strong N50 neodymium magents – the higher the number, the stronger the magnetic force exerted, with N52 being the absolute strongest currently available. This equates to a greater ability to exert force onto the diaphragm meaning a quicker transient response, higher efficiency. This enables Audeze to implement a single-sided array that contributes to the LCD-1’s very light weight design. You can read Audeze’s description here.

Ultra-thin Force Diaphragm

Audeze headphones use an ultra-ligthweight diaphragm just 0.5 microns thick – 1/10th of the thickness of a red blood cell. In turn, the diaphragm is very lightweight which permits quicker acceleration and deceleration – a quicker and cleaner transient response. Alongside the more uniform force application with Audeze’s fluxor magnet array, their drivers offer high resolution and low distortion at high frequencies due to the reduced inertia. You can read Audeze’s description here.

Unboxing –

While the box doesn’t have the luscious velour interior of Hifiman’s headphones, the LCD-1 upholds a premium unboxing experience. Sliding off the outer sleeve and opening up the hard box reveals the compact Audeze carrying case. It’s a tough and protective zippered hard shell with rugged fabric exterior. There’s an elastic internal pocket with Velcro holder that enables the user to store cables and accessories without them scratching the headphones. The headphones are comfortably secured within the case, which also showcases how they fold-up for storage. Audeze also includes a 2m cable and 3.5mm to 6.25mm adaptor and papers to verify warranty and authenticity.  

Design –

Futuristic is one of the descriptors that came to mind when I first lay eyes on the LCD-1. It’s a compendium of clean lines merged with Audeze’s signature faceplate design merging minimalism and the tradition that came before. The plastic construction is a departure from the tanky builds we’ve come to expect from Audeze, however, it is premium where it counts. The earpads and headband make an especially strong impression, employing a gorgeous lambskin leather with plush memory foam on the earpads and soft sponge on the headband. The swiveling mechanism features a metal reinforcement plate that will provide more reliable function over time. Though not the most premium in terms of overall material choice, the LCD-1 feels relatively sturdy and upholds a strong user experience.

The LCD-1 can both fold flat and fold down for storage making them very portable when paired with the included case while enabling them to hang comfortably around the neck. They offer more axis of adjust-ability than most and a nice ratcheting headband slider that lacks position markers but retains its position well. The design of the headband may present issues if you have an especially large or tall head as I found myself using the 2nd largest setting where I usually hover around the middle setting on most competitors. The tolerances are also impressive, with only a slight wobble due to the folding mechanism, but zero rattles, hollowness or creaking indicative of a long-lasting product. The clamp force is slightly higher than average but this is mitigated well by the plush earpads while contributing to strong fit stability. My only personal gripe with the design is that, when folded flat, the earcups are prone to scratching one another.

It is easy to append using some adhesive vinyl, even tape if you don’t mind the ghetto aesthetic. However, competitors such as the Oppo PM3 have small tabs that place the earcups apart, mitigating this issue. It doesn’t help that the LCD-1’s matte finish scratches quite easily even if providing a generally pleasant in-hand feel. The LCD-1 is extraordinarily lightweight in return, especially for a planar. At just 250g it is lighter than most portable dynamic driver headphones. Due to the plastic build and soft leather, I would treat the LCD-1 a little more carefully than most headphones, however, in my experience lambskin wears much better over time than the Faux leather used on the majority of competitors that are prone to pealing.

I am also enthusiastic about the included cable. It’s a dual entry design with TRRS 3.5mm plugs on all terminations. Note, even the headphone side are TRRS which means aftermarket cables are unlikely to fit, and the sound will be in mono if using a regular dual-entry TRS cable. In return, the cable is always in correct orientation since both sides offer stereo that aligns with mono connectors in the earcup jack. The cable itself is of good quality. It’s braided and smooth, but also very supple with zero memory. Microphonic noise is minimal and the cable coils very easily for storage. The metal connectors feel premium and the straight plug has great strain relief in addition to a protruded plug that makes it case friendly.

Fit & Isolation –

I am a huge fan of the LCD-1’s fit and comfort, the lambskin feels superbly soft and supple, while the heat-activated memory foam conforms perfectly to the head over time. They are an over-ear headphone and, as others have stated, the pads are on the smaller side, measuring in at approximately 3.5 x 6 cm but with a larger cavity behind. As the pads are quite deep, they did fully engulf my ears so I didn’t personally find this to form discomfort over time. As always, YMMV here. The headband is reasonably thin but well-padded. Due to the lightweight design of the headphones, they don’t wear on the head like many other either, so I was able to wear them for hours with no issue. For professionals, this will be a prime selling point of the LCD-1, their all-day comfort and the excellent wearing properties of the lambskin leather. Of course, being an open-back design do expect sound leakage in addition to minimal noise isolation. Though compact and fold-able, this makes them less ideal for portable use.
