If you want a bass-forward hybrid with genuine Knowles balanced-armature drivers and a warm, sub-woofer-style low end for music and casual gaming, choose Linsoul ZiiGaat Odyssey 1DD+3BA; if you need a featherweight aluminum build, swappable tuning nozzles, and a cable that can go balanced later, choose Kefine Delci AE Hi-Fi.
• Linsoul ZiiGaat Odyssey 1DD+3BA — biggest strength: a four-driver hybrid per side (1 custom 10mm dynamic + 2 Knowles RAF 32873 + 1 Knowles RAD 33518 tweeter) tuned for powerful, fast-decaying sub-bass with a natural midrange.
• Linsoul ZiiGaat Odyssey 1DD+3BA — biggest trade-off: at 104 ohm it is relatively hard to drive, and the heavier metal/plastic shell plus a single fixed tuning means less flexibility out of the box.
• Kefine Delci AE Hi-Fi — biggest strength: a 5.3g CNC aluminum shell (roughly half the weight of typical zinc-alloy IEMs) plus a DLC+PU 10mm driver and threaded interchangeable nozzles that let you pick warm or detail-forward in seconds.
• Kefine Delci AE Hi-Fi — biggest trade-off: it is a single dynamic driver, so it cannot match the multi-driver layering of the Odyssey, and its tuning lives in the nozzles rather than in a dedicated tweeter.
• Who each pick is for: the Odyssey suits bass lovers, musicians and audiophiles who want a fixed, characterful signature; the Delci AE suits competitive gamers, long-session listeners and tinkerers who value comfort and on-the-fly tuning.
The Odyssey is the more ambitious design of the two. Each side packs four drivers: a custom 10mm dynamic driver with ZiiGaat's Topology diaphragm, two Knowles RAF 32873 full-range balanced armatures, and a Knowles RAD 33518 ultra-frequency tweeter. That layering is the whole point. The dynamic driver handles the low end, and ZiiGaat says the topology diaphragm is engineered to increase the speed and impact of bass hits while letting them decay quickly so they don't smear the mids. The twin RAF 32873 armatures then carry the midrange, which the spec sheet describes as natural and well-textured for vocals and instruments.
The tuning philosophy is clearly stated: sub-woofer-like bass, a neutral tonal midrange, and treble shaped to match how the ear perceives tone so it stays crisp without turning sharp. If you mostly listen to bass-heavy genres, monitor your own playing, or want a set that flatters vocals without burying the low end, this is the profile you want.
Kefine Delci AE Hi-Fi: Who It's For
The Delci AE takes the opposite approach: one driver, done carefully, wrapped in a chassis built for comfort. The 10mm driver pairs a Diamond-Like Carbon dome with a PU surround — Kefine's argument is that this hybrid architecture avoids the brittleness of a plain DLC driver, giving you extended but fatigue-free treble alongside punchy, textured sub-bass. A dual-cavity acoustic structure backs that up.
The headline feature is the threaded interchangeable nozzle system. Silver nozzles lean warm and smooth, which suits relaxed listening and cinematic scores. Gold nozzles push upper-treble resolution and micro-detail, which is exactly what you want for pinpointing footsteps and spatial cues in FPS or battle-royale titles. Switching is tool-free and takes seconds, so one pair covers both a critical-listening mood and a competitive-gaming mood.
Then there's the build. Each housing is machined from a solid block of aviation-grade aluminum and weighs just 5.3 grams per side — roughly half a typical zinc-alloy IEM — with an anodized finish that resists scratches. Kefine frames this as near-weightless wear that cuts ear fatigue over long sessions. The included cable is a 164-core hybrid: 72 cores of OFC copper plus 92 cores of silver-plated wire, terminating in a detachable 0.78mm 2-pin connection. That 2-pin joint is your upgrade path to balanced terminations or wireless adapters, and the Delci AE is offered with an optional 4.4mm balanced jack.
Who should skip it? If you specifically want the depth and separation that multiple balanced armatures can bring to dense, layered recordings, a single dynamic driver has physical limits there. And if you prefer to set your sound once and forget it, the nozzle system is a feature you'll simply never touch.
Side-by-Side: Which Should You Choose?
• Best for midrange texture and vocal layering → Linsoul ZiiGaat Odyssey 1DD+3BA, which uses two Knowles RAF 32873 armatures for the mids and a RAD 33518 tweeter up top.
• Best for all-day comfort and light weight → Kefine Delci AE Hi-Fi, at 5.3g per side versus a mixed metal-and-plastic shell.
• Best for competitive gaming cues → Kefine Delci AE Hi-Fi, where the gold nozzles lift upper-treble detail for footsteps and spatial shifts.
• Best for on-the-fly sound shaping → Kefine Delci AE Hi-Fi, with its tool-free silver/gold interchangeable nozzles.
• Best for easy driveability from modest sources → Kefine Delci AE Hi-Fi, at 28 ohm versus the Odyssey's 104 ohm.
• Best for future cable upgrades → Kefine Delci AE Hi-Fi, with its detachable 0.78mm 2-pin joint and optional 4.4mm balanced option.
• Best for a fixed, characterful "one signature" set → Linsoul ZiiGaat Odyssey 1DD+3BA, if you'd rather not fiddle with nozzles at all.
In my opinion, this comes down to what you actually do with your earphones. If music is the priority and you want a genuinely layered hybrid with real Knowles drivers and a bass response you can feel, I would buy the Linsoul ZiiGaat Odyssey 1DD+3BA — just plan on pairing it with a source that can handle its 104 ohm load. If you split your time between gaming and listening, or you wear IEMs for hours at a stretch, I would buy the Kefine Delci AE Hi-Fi instead. The 5.3g aluminum shell, the swappable nozzles and the upgrade-ready cable make it the more adaptable everyday tool. Neither is a compromise pick — they're just aimed at different buyers.
It's rated at 104 ohm with 104 dB sensitivity, which is on the higher-impedance side for an IEM. It will work from a phone or basic dongle, but a dedicated amp or a stronger portable source gets more out of it. If you only have a weak output, the 28 ohm Kefine Delci AE is the easier match.
They're two tunings in one pair. The silver nozzles give a warmer, smoother presentation suited to relaxed listening and cinematic scores, while the gold nozzles raise upper-treble resolution and micro-detail for competitive gaming and critical listening. You swap them by hand, no tools needed.
For competitive titles I'd lean toward the Kefine Delci AE Hi-Fi, because the gold nozzles are explicitly aimed at footstep and spatial-cue retrieval and it runs at zero-latency wired output. The Odyssey is still perfectly usable for gaming and will sound fuller on explosions and soundtracks, but its tuning isn't built around positional detail the same way.
Yes. The Odyssey uses a 2-pin detachable cable, and the Delci AE uses a detachable 0.78mm 2-pin connection with a 164-core hybrid wire and an optional 4.4mm balanced jack. Since I don't quote prices here, check the current price on Amazon for each before deciding.
