Introducing our new large sized 18AWG pure copper wire designed for full-size headphones.

Through experimentation and striving for maximum performance, we developed our largest wire to date. To achieve the desired ergonomics and performance we were looking for, it was paramount that the XL wire incorporates certain elements that have made our designs successful. Based on our signature Type 6 design, the added thickness allow us to significantly increase groups bundles to 36 (compared to just 6 on 26AWG wire) to nearly eliminate electrical resistance to improve output power, making it more efficient to drive all IEM and headphones on any source. We also implemented varied dampening cores for the first time, allowing us to do a number of things: maintaining a round shape for consistent conductivity, prevent mechanical vibrations that will affect interference and interruptions, plus softens the XL wire to make it as flexible as its smaller counterpart for on-the-go use. In addition, each wire strand comes with enamel coating over silver layer to decrease electrical anomalies (i.e. skin and proximity effect) and preventing oxidation (i.e. turning green) over time to maintain same cosmetic aesthetics for many years. Our proprietary outer insulation is one of the best on the market and used on XL wire for maximum flexibility and durability. Once they are produced, XL wires will undergo deep cryo treatment to align crystal boundaries more closely to each other to transmit electrical signals faster with less distortion and low electrical resistance, and reducing noise to permanently maintain excellent sound quality.

This unique 2-wire X cable consists of one 18AWG XL wires per channel intended for full-size headphone use. If you are looking for a performance cable that has a highly refined copper sound with excellent ergonomics, you won't find another quite like this one.

Reviews:

"The PLUSSOUND Copper XL adds a touch of richness and warmth, as one would expect from an all-copper cable, but surprisingly for me, the level of detail rose as well. Better clarity helped with instrument placement and provided a succinctness to the tonality that showed well without becoming dry or analytical - seemingly two antithetical responses when dealing with previous all-copper cables." Linn, headfonics.com

"Based on my testing, I found PLUSSOUND Copper XL sound characteristics to be aligned with a more common copper cable performance, but there is still a bit of a twist here. Typically, I find pure copper cables to lift both low end and upper end, adding more weight to the bass and more sparkle to the treble. Copper XL does follow a similar footprint with more elevated and textured sub-bass rumble and higher resolution upper mids due to the improvement in treble definition. But the treble itself remains natural in tonality without adding too much harshness. Also, due to a more mid-centric focus of the imaging, the sound signature remains balanced regardless of the added weight in bass and some lift in treble. Thus, you don't have to worry about the sound sig of your IEMs becoming skewed towards a more V-shaped signature." Alex, twister6.com

"The Copper XL stands out as an exemplary copper cable, showcasing musicality with its full and dynamic mid-range, alongside excellent timbre. It offers a resolving sound characterized by a rich presentation and precise imaging. With its emphasis on musicality over technicality, the Copper XL delivers a vivid portrayal of recordings, making it a compelling choice for those seeking an engaging and immersive listening experience."
