Over the years, we have extensively covered various products by PlusSound. For those keen on delving deeper into their offerings, you can explore further here.

PlusSound SPC XL

The latest offering from PlusSound, the SPC XL, is their first product that features larger wires (18AWG). This new wire is PlusSound’s biggest wire thus far. Based on their signature Type 6 design, the increased thickness allows for a significant increase in group bundles to 36, compared to the previous wire (26AWG) which only had six, eliminating electrical resistance to enhance output power. This makes it more efficient to drive any IEM and headphones on any source.

Furthermore, PlusSound has introduced varied dampening cores, enabling them to maintain a round shape for consistent conductivity, prevent mechanical vibrations that can cause interference and interruptions, and soften the XL wire to make it as flexible as its smaller counterpart for on-the-go use. Additionally, each wire strand has an enamel coating over a silver layer to decrease electrical anomalies and prevent oxidation over time, maintaining the same cosmetic aesthetics for many years.

PlusSound Copper XL

The Copper XL cable is made up of 36 wire bundles of pure UP-OCC copper that are arranged in a custom Type 6×6 Litz configuration. Each wire bundle has multiple dampening cores, including a large primary centre core. This design results in a soft and pliable cable that maximizes conductivity and performance. The Copper XL cable shares identical mechanical components and design with the SPC XL cable, except that it uses pure copper instead of a silver-plated copper configuration.

Expect a highly refined copper sound with a wide soundstaging and excellent transparency not found in other cables.


Opening a PS package from any cable manufacturer is an experience like no other. The XL cables are delivered in a sleek black box with reflective stickers on it. The box contains a plexiglass window that reveals the cable’s origin – it was designed and handmade in LA, California.

Inside the box, the cable is nestled in a leather pouch, a luxurious touch, in my opinion. The package also includes some additional accessories such as a cleaning cloth, a leather strap, and a warranty card. All the accessories, except for the leather cable binder, bear PlusSound’s logo. Overall, the unboxing experience is top-notch.

Build Quality and Ergonomics

PlusSound has come a long way in terms of build quality. and they now use custom hardware for connectors and plugs, in this case, the cables have fantastic quality.


The cables are nicely braided with good consistency. The hardware, on the other hand, is incredibly good. My set came with all silver/copper accents with 2-pin connectors and a 4.4 mm termination. The 2-pin connectors have to go with logos facing inwards, as the screws have to go out, contrary to many other manufacturers.

The 4.4m plug is the highlight of the cables to me, as it fits any 4.4 output snugly. The quality and the finish are excellent. Also, there’s no visible heat shrink from plastic or any other flexible material. Instead, the 2-pin connectors and the plug are finished with aluminium rings, so the cable looks very sharp and clean. The Y-split and chin slider on the cables are aluminium. Overall the cables are fantastic in terms of build and design.

In terms of comfort, these 18 AWG cables are not the most comfortable or the lightest, as you feel a certain weight whilst using them. So if you plan to get either of these, you shouldn’t seek the best comfort for on-the-go use. The positive thing is the flexibility, which is impressive despite the thickness of the cables. Microphonics is very low, and it’s reasonably comfortable around the ears. But there are many cables on the market with more flexibility and comfort for sure, they just don’t come with 18 AWG.

A keen audiophile and hobby photographer, Berkhan is after absolute perfection. Whether it is a full-frame camera or a custom in-ear, his standpoint persists. He tries to keep his photography enthusiasm at the same level as audio. Sometimes photography wins, sometimes his love for music takes over and he puts that camera aside. Simplistic expressions of sound in his reviews are the way to go for him. He enjoys a fine single malt along with his favourite Jazz recordings.
