Compared to Satin Audio Zeus I (Review link)
The first cable that I’d naturally compare with is Satin Audio’s first flagship cable, as well as the forefather of Zeus II – the Zeus I. Along with the geometries and materials being different, the Zeus I (or Zeus OG) uses a classic braiding style and form factors with 24awg wires, whereas Zeus II has been changed to use thicker 22awg wires. The product positions of Zeus II and Zeus II Eternal are each equivalent to the 4-braid and 8-braid Zeus I.
The sound of Zeus II thoroughly continues the legacy of Zeus I, staying very consistent with what Zeus I offered but overhauled in performance. The Zeus II is more holographic, providing a more three-dimensional and immersive headroom than the Zeus I. The bass is thicker in tone and extends more deeply and wholesomely. Vocals also got higher in definition and textural details.
The trebles gained a major improvement too, having the Zeus II play trebles with better separation, clarity, and refinedness. The background is noticeably quieter and darker on the Zeus II, which better introduces the immersiveness of the music. The soundstage is adequately larger than the Zeus II, particularly improved in defining different layerings. Overall, Zeus II continues the lush, gently oiled up timbre that Zeus II had, but now with better technicality from front to back – especially the upper frequencies and soundstage.
Compared to Eletech Sonnet of Adam (Review link)
Sonnet of Adam (SOA in short) is one of Eletech’s flagship custom cables made with meticulous combinations of different rare metals like Zeus II. Both are in the same tier and share a similarity in the sense that they are all-rounder cables bringing an improvement across the entire spectrum, though they’re quite different. Compared to Zeus II, SOA is more laid-back in presentation, approaching the sound more carefully and calmly. Instead of toning down the dynamics a bit, SOA instead focuses on highlighting the gentle sways of silky textures.
The bass nuance from these two cables is similar but surely different once I start paying attention to the details. Zeus II better portrays the power and liveliness, while SOA is more mellow and focuses on bringing out the delicate overtone and reverbs. I could also summarize these differences as Zeus II prioritizing the strikes / how the sound approaches, whereas SOA does so for the decay / how the sound ends. Zeus II is masculine, and SOA is feminine in nature.
The Zeus Has Returned, Now Even Stronger.
With the portable audio market becoming increasingly competitive, especially in the high-end custom cable space, it’s getting harder for us audiophiles to find a cable that truly stands out without relying on exaggerated tuning shifts or flashy claims. Zeus II doesn’t play that game. Instead, it focuses on refinement, consistency, and maturity—qualities that become more apparent the longer you listen. Rather than dramatically altering an IEM’s sound signature, Zeus II works by strengthening what’s already there.
It deepens tonal density, cleans up the background, and improves extension and separation across the board, all while keeping the original character intact. This makes Zeus II an easy and reliable pairing choice for many high-end IEMs, especially those leaning neutral, warm, or slightly thick in presentation. Compared to the original Zeus, Zeus II feels like a confident return. Not a reinvention, but a well-judged evolution. Zeus II carries forward the lush, smooth timbre that defined Zeus I, now with better stage definition, cleaner layering, and more refined highs – and, of course, the strengthened adaptability in both terminations and color personalizations.
Against other TOTL cables, Zeus II positions itself as a balanced all-rounder: lively and engaging, yet controlled and fatigue-free. Zeus II isn’t a cable that tries to impress you in the first five minutes. Instead, it wins you over through long listening sessions, where its composure, tonal richness, and coherence quietly reveal why Satin Audio waited five years to bring Zeus back. If you’re looking for a flagship custom cable that is created to last sonically, functionally, and aesthetically, Zeus II is a must to consider as you consider gifting your IEM with an endgame cable to be paired with.
