DISCLAIMER: PlusSound provided me with the Exo Silver + Gold in return for my honest opinion. I am not personally affiliated with the company in any way, nor do I receive any monetary rewards for a positive evaluation. The review is as follows.

PlusSound is an American cable manufacturer based in Los Angeles, California. Founded in 2012 by Christian Oliver, the company specialises in aftermarket cables, but they’ve since ventured into developing amplifiers, as well as a series of in-ear monitors. PlusSound is unique among its peers in how it presents its products. Instead of separating them by metallic composition, each product category determines how the conductor itself is treated. The Apollonian, Dionysian, Echo and Poetic line-ups all contain different methods of shielding, while the X, Exo, X6 and X8 line-ups feature unshielded cables in their individual wire counts. The user is then free to choose whatever metal composition they’d like – creating an exploratory and customisable shopping experience. Today, we’ll be looking at the Exo Silver + Gold: The 2018 iteration of a PlusSound classic, sporting a thrillingly energetic and surprisingly balanced signature for all to enjoy.

Even before my first listen, PlusSound’s visual presentation immediately impressed. The Exo Silver + Gold comes in a beautiful, well-thought-out and compact package. While it’s neither as luxurious as Effect Audio’s pricier offerings, nor is it as simple as something PWAudio would provide, Christian has found the perfect balance somewhere in between. Covered all round in a striking matte-black finish, embossed with shimmering PlusSound branding and topped off with a firm magnetic latch, the box simply oozes class. Inside, you’ll find a PlusSound brochure, an elastic band – for your stacked rigs – and the cable itself within a protective plastic wrap. Again, the Exo Silver + Gold was packaged with admirable restraint and excellent finesse. It showcases outstanding attention to detail without going over the top, and it’s a testament to how much care Christian and his team put into their products beyond just performance.


The Exo Silver + Gold comes equipped with PlusSound’s brand new PS Insulation. While my two-year-old Exo Tri-Metal has aged well cosmetically and ergonomically, their latest innovation exhibits obvious improvements on all fronts. Visual transparency is one, displaying the Exo Silver + Gold’s silvery strands with aplomb. They don’t shine as radiantly as Effect Audio’s conductors do, but there’s a lot to love about its more understated and less bling-y look. Ergonomically, the cable warrants another comparison to the Singaporean giant. Effect Audio has been my clear personal frontrunner when it comes to weight, suppleness and pliancy. With PS Insulation, PlusSound is looking to close that lead. The Exo Silver + Gold showcases great flexibility and minimal weight, besting a majority of its competition on looks and feel alone. PS Insulation may prove to be Christian’s ace in the hole – an element usually underrated, but brilliantly effective.

Sound Impressions

The Exo Silver + Gold is a cable that prioritises contrast, energy and excitement. Impressively, though, it does so whilst compromising neither body nor timbre – as is the norm in fun-oriented cables. Although specific dips and peaks have optimised the cable’s dynamic performance, the Silver + Gold maintains excellent linearity – ensuring great tonal balance throughout its frequency response. It sports a moderate W-shape and structures a clean stage. With an especial focus on width, it dons a pitch-black background perfect for those transients to cut through. Through mid-bass control and an upper-treble lift, the Exo excels in headroom; exuding openness and air without resorting to any sense of brightness. Neutral would be a more apt term to describe its tone, sparing organicity through a bodied and resonant midrange.


Bass is the highlight of the Exo’s presentation. Amalgamating the cable’s two greatest strengths – dynamism and control – the Silver + Gold increases low-end impact whilst managing bloom all at the same time. By attenuating the mid-bass and improving low-end extension, the Silver + Gold provides punch with clarity; balancing musicality and technicality with grace to spare. Upper-bass is the definite focus of the Exo’s signature, while sub-bass rumble exists purely out of extension. Instruments like tom-toms and upright basses benefit from this region’s impressive clarity and layering, giving listeners the ability to detect harmonic nuances as they decay into the background. Finally, low-end tone is on the brighter side – due to an upper-treble peak – but the aberration is slight at best. The Exo Silver + Gold prides its bass as the epitome of its philosophy: Energetic and restrained, vibrant and disciplined, impactful with finesse.

The Exo handles midrange with great balance – sporting a linearity often sacrificed for clarity and energy. Where brighter-sounding cables would often attenuate the lower-midrange, the Silver + Gold maintains body here well. There’s neither a cloy-ness nor a chestiness that tampers with vocal presentation; instead, just enough weight to endow notes with proper heft. Instruments are forwardly placed with excellent presence, and tone errs on neutral for versatility. A lift in the upper-midrange gives the Exo both the air and the zing it needs to complement its contrast-y signature. Transients cut brilliantly, showcased most prominently with snare drums in busy metal tracks, and percussion and keyboards in jazzier recordings. But, none of those jabs ever sound thin or hollow or artificial, all because of the midrange’s excellent balance – proving that bright and bold can exist in the same signature with brilliant harmony.


In the treble, PlusSound – again – displays great sophistication. A calmed lower-treble ensures smooth sailings for the Exo’s dynamic attack – ensuring transient energy without a hint of brittleness. The Silver + Gold instead draws its air from the upper treble. A rise in the 15kHz range brings an assured sense of clarity. But, this is also where the cable gains its bright-ish signature. It’s neither dry nor thin, but it definitely shines brightest (no pun, intended) when paired with warmer transducers. Great extension benefits its wide and open stage – conjuring a pitch-black canvas for optimal detail retrieval. And, this aids separation as well, showing admirable organisation along the x-axis. The Silver + Gold’s top-end is its most crucial component; the tentpole for its entire philosophy. Thankfully, it beams with restraint. Clear, calm and collected, this treble is the Exo’s moist, fluffy sponge as much as it is its cherry on top. Well done.

PlusSound Exo Tri-Metal (now discontinued; the new Exo T-Metal retails at $449.99)

The only other PlusSound cable I’ve ever carried with me is my two-year-old Exo Tri-Metal – a 4-wire cable comprised of copper, silver and gold. This was long before Christian developed his new PS insulation, and that definitely shows. Although the Tri-Metal is still a decently ergonomic cable, it simply can’t compete with the Silver + Gold’s softness, suppleness and weight. Visuals also benefit from the upgrade, while the Tri-Metal is beginning to show cloudiness from age. PS Insulation has made the Silver + Gold a touch thicker, but it’s at absolutely no consequence. The PlusSound branding on the latter has worn out significantly as well, but only time will tell whether or not the same will happen to the Silver + Gold. Even on looks and feel alone, the Silver + Gold is a vast improvement over its aesthetic predecessor.


The Exo Silver + Gold serves as a sonic foil to the Tri-Metal. Both cables maintain excellent top-to-bottom balance, yet they each have traits that significantly set them apart. The Tri-Metal is a warmer shade of neutral, while the Silver + Gold maintains as much cleanliness as smoothness allows. And, to this end, the latter is the more exciting cable – more dynamic and aggressive in its approach. A large majority of it has to do with differences in soundstage depth. Seemingly, the Tri-Metal is the winner here, due to its calmer overall midrange. However – because of okay treble extension – this lack of presence soon morphs into fatigue; vocals begin to sound recessed as a result. Despite its upper-midrange tilt, the Silver + Gold excels in instrumental energy – serving a more reasonable amount of body to complement its deft articulation. Pair that with great organisation, and you have yourself a better foundation for the overall presentation.

The bass is a significant contributor towards the Tri-Metal’s warmer tilt. There’s a clear emphasis on the mid-bass that gives the cable a slight bloom. It’s a richness that permeates the soundstage with a euphonic warmth, improving musicality and cohesion between notes. However, due to lacklustre extension, this bloom interferes with bass definition. By comparison, the Silver + Gold displays greater technical finesse. Low-end notes come through with strong outlines, palpable layering and commendable resolution. The upper-bass focus does impart a slightly brighter tone, but – considering the improvements in transparency – it’s a welcome trade. The Silver + Gold is all about cleanliness, precision and punch, while the Tri-Metal has its heart set on organicity and warmth. This trend continues into the midrange, where the latter is more linear between the lower and upper registers. The Silver + Gold – again – is punchier here, with a slight disadvantage in overall tone. But, its sheer transparency is head and shoulders above its little sibling.


The treble is truly where the Silver + Gold cleans house. Open, airy, articulate and smooth, it has the hallmarks of a technically impeccable top-end. By comparison, the Tri-Metal has a more linear upper-treble, but its largest misstep is extension. Unfortunately, where the Silver + Gold shines brightest, the Tri-Metal lacks sheer reach in order to pull its entire signature together. Although its aim at a natural tone is admirable, it suffers from a bloomy low-end and okay stage organisation as a result of its technical shortcomings. It’s certainly not bad by any stretch of the imagination, but the Silver + Gold is the clear victor here. The new Exo variant boasts a pitch-black background – creating gorgeous contrasts against transients – superior precision and better versatility. I struggle to make sense of the Tri-Metal with darker-sounding IEMs, while it performs brilliantly with brighter transducers. The Silver + Gold will maintain technical finesse regardless of its pairing, and will never serve as a bottleneck to anything it’s attached to.


The PlusSound Exo Silver + Gold is a shining example of how fun should translate in the aural realm. Boasting excellent balance between dynamic energy and vocal weight, it truly is style and substance. Through crafty tuning and sheer wit, the company has created a cable that has its cake and eats it too. The Exo takes the qualities of a clarity-focused, articulative and impactful presentation, and refines it with finesse, elegance and grace. Bass remains beautifully controlled despite its punch, instruments carry equal servings of cleanliness and weight, and the treble glistens without a brittle note in sight. Besides its neutral-bright tonal balance, there’s not much I can fault the product for. With the Exo Silver + Gold, PlusSound have once again proven themselves as a force to be reckoned with. If this is the kind of quality we can expect from them in the future, then 2018 is shaping up to be one heck of a calendar year.

Pros: Ergonomics, build quality, customisation options, clarity, detail, bright and still smooth
Cons: Not the most natural sound, short note decay, synergy with A&K AK70 balanced out

PlusSound is probably best known as an aftermarket cable company, and indeed it all started when Christian Oliver thought it would be a nice project to build a cable for himself back in 2012. Soon after he found himself building cables for other people and a simple DIY project snowballed into the company PlusSound. While perhaps for the time being still best known for aftermarket cables, PlusSound has continued develop in the same entrepreneurial spirit it started off with by adding interconnects, accessories, their Cloud Nine Amplifier, and very recently even three brand new earphones of their own; the Spectrum, Prism and Gamut.

PlusSound has essentially grown into a one-stop-shop for audiophiles, which is not surprising considering Christian is himself a life-long audiophile. Indeed it seems that the driving force behind PlusSound's innovations stems from the same desire that drives all audiophiles to constantly expand their collection of gear. And much like every audiophile has their own preferences, so to do I sense a common theme among the various products PlusSound offers. It seems like everything is designed to be used, used again, and then used some more for good measure. It is a "utilistic" design, which is probably a horribly pseudo-academic buzzword I picked up while working with the wrong people, but it seems nonetheless appropriate here. Everything looks akin to that very pretty set of high-end tools your dad never let you use.


Build quality
This brings me to the main reason why I became interested in PlusSound, that (sorry for using the term again) utilistic design. It looks rock solid and that is important for someone like me who is an idiot and will break everything he gets his hands on.

When I received the cable it came in the newly designed packaging, an elegant satin black box with glossy artwork, that opened up to reveal a PlusSound branded rubber band for stacking and of course the Exo cable itself. It was great to immediately notice that the cable not only looked solid, it felt it too. The parts such as the 2-pin connectors and termination are light in weight, but feel very strong. The y-split is chrome aluminium with silver aluminium slider and they look and feel great. Moreover, PlusSound offers many customisation options and I love how Christian made a cable where all the details match the colour of the material used in the cable itself. So a silver cable with chrome logos on the plug and connectors, chrome y-split and silver slider, it all works very well together to make a great looking cable. This is something I really like about PlusSound, it is great fun to not just look at the various materials that they offer for the cable itself, but also the many parts and in some cases even the type of braiding. It feels like designing your CIEMs, a real custom experience!

Of course the big new thing about this particular Exo cable was that it came with the newly released PS insulation. Christian explained it was a great improvement over the previous insulation and so I made sure to borrow an older Exo cable from my friend Oscar in order to compare. As soon as I picked up the cable I was very impressed by its suppleness. It is slightly thicker due to the insulation, but incredibly supple for a 4-wire cable and as such very comfortable to wear. In part this could also have to do with the lack of pre-bent heat shrinks as ear guides, something that does make me wonder about what long-term (years) use will do to those parts of the cable due to rubbing and skin oils that can affect the insulation. Time will tell, but for now it is a gorgeous looking and feeling cable that I can use for hours on end without any sign of discomfort or worry about the build quality.

Usually I briefly list the source I use because the source itself has an impact on sound, but I don't really go into it beyond that. Not in this case because while the cable is terminated in 2.5mm TRRS for the balanced out on my AK70, I actually ended up using it from SE out (via an adapter). The reason for this is that the laid-back nature of the AK70's balanced out did not, to my ears, synergise well. It caused a loss of resolution (not detail) and dynamics. While the resulting sound was certainly very nice and as easy on the ears as a breath of fresh air cooling your face on a warm summer's day, it was technically not at all what I expected to hear. Note decay seemed extremely short, resulting (for instance) in less texture to strings and the strike on a tympani would miss its natural resonance. Switching to the SE out livened up the sound and to me sounded much more crisp and clear, with the resolution I was expecting to hear. So all impressions are based on using the Exo from the SE out on my AK70, unless stated otherwise. The IEMs used were the Custom Art Ei.3, Rhapsodio Saturn and briefly the Rhapsodio Zombie.


The Exo Silver + Gold is a brighter cable aimed primarily at improving detail retrieval and clarity, and in this it performs remarkably well. It has a short note decay that means it is not the most natural sound, but what this does is create a wonderfully airy and detailed image that is incredibly precise in its placement of notes. Notes sit with great confidence in the image and are crisp and clearly defined against the background. The stage is well extended creating a large image with outstanding separation. My Custom Art Ei.3 are normally warm and smooth with thick notes and quite an organic sound, but the Exo changes that to thinner, very well defined notes that provide excellent layering. When listening to Beethoven's Missa Solemnis I was really impressed by how well the different sections of the choir were defined.

While the Exo separates everything very well, it is not at the cost of coherency and while bright and clear, it stays musical and smooth. With warmer IEMs emphasis in classical music shifts towards the string sections and yet they don't overpower the bass section. There is enough impact there to ensure those come through with enough presence to maintain a sense of harmony. It is not as strong as in some copper-based cables I have used, but it never becomes clinical or boring and I often found myself getting carried away in the airy and detailed, yet wonderfully flowing sound this created.

The bass of the Exo Silver + Gold is tight and hits hard, something I believe is quite often found in silver-based cables. The mid-bass is reduced to create a brighter tone and the sub-bass is extended to hit hard and bring some excitement to what might otherwise become a boring signature. This means the Exo will work well with warmer IEMs and when Christian told me what he was sending over, I knew exactly what I wanted to pair it with... The Rhapsodio Saturn. The Saturn are warm, bass-oriented dynamic driver IEMs that I had previously tried pairing with copper-based cables and it just made the Saturn weak in the knees. All fluff and no punch. Well, the Exo certainly solved that issue! Oh boy does the Saturn's bass have a nice kick to it! I keep getting caught off guard when listening to Carbon Based Lifeforms' album Interloper, where the first track has a nice deep bass, but the second track, 'Right Where it Ends', punches Right Between the Eyes! In fact, just for the bass alone I will keep the Exo paired with the Saturn, but the synergy has a whole is excellent and really did for the Saturn what I was hoping for.

Of course I also tried my trusty Ei.3 and those are tuned for EDM with a fast and tight bass that was complimented by the Exo. The reduced mid-bass does brighten up the signature more than I would like for EDM, but the tightness and impact of the bass still provides plenty of energy. Moving on to classical music I found that, as expected, the bass section was lacking its natural decay and the presence of the bass section was greatly reduced. While this was not in line with my personal preferences, I can readily see how it is something that might well suit others. The bass section was pushed back, but thanks to its sub-bass impact and the excellent clarity and separation of the cable as a whole, still easily discernable. It makes for a more composed signature and ideal for someone more interested in hearing the violin, rather than having the tympani thunder all over it or the cello moving in front all the time.

Bright, clear and detailed mids, that is what you can expect from the Exo Silver + Gold. When listening to classical music I am impressed by how well it separates the various instruments. When I listen to Brahms' 4th symphony the many layers usually melt together in a stream of complicated, but very enjoyable music. With the Exo all the different layers are picked apart while still retaining a connection between the layers. Not the most harmonious, but enjoyable in its own way. It becomes very easy to pick out a single instrument to focus on and in general I found details to come through even when I was not paying much attention to the music.

Due to the brighter tonality the Exo favours female vocals, which are presented bright and very clear, but maintains a comfortable smoothness. While I was adjusting to the brighter tonality I had a few moments where I braced myself, as soprano Elin Manahan-Thomas would push for the high notes, and yet every time the Exo proved itself capable of providing brightness while still doing justice to that crystal clear voice. Male vocals lack a bit in body, which is more noticeable the deeper the voice, but like bass instruments they are still easily discernable. This means that while the choir might sound a bit brighter overall, every voice can still be found with great easy. This is, I think, a great example of the trade-off the Silver + Gold makes. It gives up some of its natural tonality in order to reveal more detail, more easily.

The Exo Silver + Gold is a silver cable with added to it a small percentage of gold in order to avoid some of the pitfalls of a pure silver cable. One area where this is important is the treble. Silver cables can push it a little far and as a result cause some sharpness, but the addition of gold seems to do the trick, as this is clearly not the case for the Exo. I am pretty sensitive to treble spikes and find the Exo's treble to be comfortable and non-fatiguing. It is a bright and airy treble that does not push too far forward, but again is lacking a little in natural sparkle. This is very noticeable in the Nutcracker's 'Dance of the Sugar Plum Fairy'. While the fairy dances light on her feet and twirls through the air, I am missing the hint of fairy dust in the celeste (the main instrument used). Perhaps in this case it is more a 'plum fairy', missing the sugar found in copper cables to add sweetness to the notes. Indeed my preferences clearly differ here, but the trade-off makes sense. The treble is precise, clearly defined and adds lots of air to let the stage breath. Even the Saturn, which I felt lacked a little in the highs, got a better-defined and more easily discernable treble to them. Another reason why the Exo is staying on them.


-Exo Copper-
(This comparison was done with both cables from the balanced out.) Both cables are part of the Exo series, but the Silver + Gold has of course the new PS insulation. The improvement in ergonomics is significant; the new PS insulation makes the Exo very comfortable and less likely to push or pull on the IEMs when moving around, something I noticed with the older insulation.

In terms of sound the two cables offer differences in line with what can be expected based on the materials. The Exo Copper is a warmer cable with a more natural tonality and while it offers more air than most copper cables, the Silver + Gold easily outperforms it in terms of air and clarity, as well as stage dimensions. The Copper offers a warmer and more intimate setting by comparison. The bass of the Copper is thicker and does not go very deep, whereas the Silver + Gold has a very tight and hard-hitting bass. In the mids I find that the Copper does not do vocals quite as well. Vocals are clear, but not entirely clean, something I noticed quite clearly while listening to Caro Emerald, where her voice was not entirely smooth when paired with my Ei.3. The Silver + Gold does vocals better both in terms of clarity, as well as smoothness. I loved how I could hear every breath of London Grammar's Hannah Reid. In the treble I found that the Copper had a warmer tone, but it was a little bit more forward to better balance with the stronger bass presence. The Silver + Gold by comparison had a brighter, slightly more sharply defined treble, that was nonetheless never harsh.

I would say the Copper is the more exciting cable, whereas the Silver + Gold is the more even and easy-going cable. It is very pleasant to listen to and almost has something ethereal to it by comparison.


-Effect Audio Lionheart-
In terms of build quality these cables are very close. The Exo has lighter and slightly bigger parts, but both feel very durable. While the cable is thicker, I would give the Exo the edge in suppleness, but in comfort I find both equally great to use.

Lionheart is a copper-based cable with a warm, very natural and incredibly harmonious sound, and it will come as no surprise that given my preferences this is my current favourite cable. It is also more expensive than the Exo Silver + Gold ($499.90 vs. $349.99), but it is interesting to illustrate how each cable has its own strengths. There is a clear difference in presentation between the two and very noticeable in the note decay I have mentioned previously. Lionheart has quite resonant notes that contribute to the very natural character of the cable. Combined with a warmer tonality, it allows for instruments to separate based on tone, where the Exo separates instruments by creating air around them. Notes on the Exo are more clearly defined and a bit thinner, which allows for details to come through more easily. In this I feel that Lionheart is the more engaging cable that demands your attention, whereas the Exo is more easy-going and will present all the details to you even if you are not paying full attention. It might therefore well be that for casual listening, the Exo comes across as the better cable. For bass Lionheart has less sub-bass impact and more mid-bass presence, while the Exo is clearly much tighter and hits harder. In the mids both cables are clear. Lionheart has sweet, alluring mids with amazing vocals, whereas the Exo has mids that are like a bright clear day, offering crisp and clear vocals and well-defined instruments. In the treble Lionheart is by comparison a little more attenuated but I feel better extended, with a sweet sparkle to it. The Exo once again presents a clear and crisp sounding treble that is a bit brighter.


The PlusSound Exo Silver + Gold presented me with an interesting paradox that I think very nicely illustrates the quality of this cable. The brightness and clarity it brings is not at all in line with my preferences, I prioritise tonal accuracy and generally gravitate towards a warmer sound, yet I still end up coming back to the Exo to provide me with a fresh, cool breeze to clear my mind. In fact, the Exo became a firm favourite of mine to pair with the Rhapsodio Saturn and I look forward to experimenting with source synergy and other IEMs at a later date, as I feel the Exo presented me with a really interesting experience with a brighter and clearer sound and there is more to explore yet.

The Exo Silver + Gold is an excellent cable. It has a great build quality and the new PS insulation creates an incredibly supple and comfortable cable. I feel it is a great option for those looking to improve clarity and detail in their IEMs.
Pros: Clarity, smooth, soundstage
Plussound Exo Copper
Type 6 Litz UPOCC Copper

Used with my Audio Opus #2 / iBasso DX200 DAP's / Objective2 amp and my Inearz P350 custom monitors / 64 Audio U6 / Noble Sage / Clear Tune VS-2


Packaging, Build quality and Ergonomics:

The Exo comes in a nice black Plussound box with the company logo on the front, open this up and the cable is sealed in a plastic bag along with a business card and a couple of rubber amp straps. The packaging is more than just a standard bag with a cable in, and feels quite premium for the price. Well presented and very professional, great packaging here.

The Exo cable is superbly built with a very even braid, solid metal connectors and y-split with excellent strain relief on all parts. It feels like a very well built cable that will last a long time but also looks superb. There are no flaws whatsoever in the build.

This cable has no memory wire which to me is a plus, the heat shrink is angled so you know which way they go though. The cable is supple and very comfortable in use; the y-split is fairly big but lightweight. One thing that could be improved is the chin slider; it is not very tight and tends to slide down on its own. But overall the cable is the perfect balanced between cable thickness and ergonomics, being a little stiffer than the Effect Audio offerings. No cable noise was detected when using this cable.




The Exo Copper is one of Plussounds more affordable models, but don’t let this fool you. The cable uses litz copper and is one of the cleaner sounding copper cables out there. Firstly the soundstage is improved being wider and having more air between instruments, this also improves instrument separation and everything is a little more defined within the soundstage.

Bass tones are slightly fuller than most stock cables, digging deeper with better definition, one thing that stands out is kick drums are backed up with better body but there is no hint of bloat anywhere. The midrange gets an extra bit of air around instruments, increasing separation and everything sounds a little crisper. The highs are not boosted, instead just like the midrange they gain a bit of extra definition and air, extending with ease. This cable is slightly full bodied but with extra air and definition bringing out extra detail in your IEM’s.

So the Plussound Exo Copper is a slightly full sounding, but very detailed and open copper cable. It is not a full as the Atlas Zeno IEM, but provides better air and separation and it is not bright which means it pairs well with most IEM’s. I have been enjoying the Exo a lot with the Clear Tune VS-2 monitors.
