• CCA KZ ZST X — biggest strength: a 1BA + 1DD hybrid setup (10mm dual-magnetic dynamic driver plus a 30095 balanced armature) with a V-shaped signature, prominent sub-bass and a wide 20 Hz–40 kHz range. It's the more musical of the two.
• CCA KZ ZST X — biggest trade-off: it's tuned for enjoyment first. The bass boost and lively treble are great for music, but that coloration can mask the small positional cues competitive shooters depend on.
• KZA COUSTICS Axas — biggest strength: a purpose-built gaming IEM. Deep in-ear seal, 10–20kHz range, spatial audio tuning, and hardware-level AI noise cancellation for stable in-game voice chat.
• KZA COUSTICS Axas — biggest trade-off: it's sold as a 3.5mm NO Mic variant. No inline mic means no calls or voice chat through the cable itself — you'd rely on your PC or controller mic instead.
• Who each pick is for: CCA KZ ZST X → music listeners who game on the side. KZA COUSTICS Axas → gamers who want positional audio and isolation above all.
The ZST X is the enthusiast's pick of this pair. CCA built it around a hybrid driver configuration — a 10mm dual-magnetic dynamic driver handling the low end and a 30095 balanced armature covering the upper frequencies. In practice that means punchy, plentiful bass with a sub-bass boost you can feel, plus clean mids and highs that stay detailed rather than getting buried. The soundstage is described as fully balanced with good width and depth, and the overall signature is V-shaped, which is exactly the tuning that makes music, movies and casual games feel lively.
At 12 ohm impedance with a 20 Hz–40 kHz frequency range, it's an easy load for a phone, laptop or controller jack. The build is more premium than the price class suggests: a 4-strand silver-plated cable, a 3.5mm gold-plated plug, and a 0.75mm 2-pin detachable connection so you can swap or upgrade the cable later. The resin housing comes in a cyan finish, and CCA claims the seal blocks at least 90% of external noise — useful on a plane, on a run, or when you just want to disappear into a mix. There's also a built-in HD mic with noise handling that reduces cross-talk and background static.
Buy it if you want one earphone that sounds genuinely good with music and is good enough for gaming on the side, and you value the detachable cable and mic.
KZA COUSTICS Axas: Who It's For
The Axas is a different animal entirely: it's a gaming-first in-ear monitor. The whole design brief is competitive play. KZA uses an ergonomic, lightweight silicone-bud shell with three tip sizes (S/M/L) so you can get a secure, snug fit — the company specifically calls out no pressure and no slipping across long sessions, which matters when you're three hours into a ranked grind. That deep in-ear seal is the foundation of everything else it does.
That seal drives the passive noise isolation, and it's the reason the Axas can create what's described as an intimate soundstage — the kind of closed-in acoustic space where positional audio cues read clearly. The 10–20kHz frequency response is tuned to lift footstep detail and spatial information, so directional sounds sit forward in the mix rather than behind a wall of bass. There's also hardware-level AI noise cancellation aimed at filtering ambient noise so your in-game voice chat stays crisp and stable.
Build-wise you get a 2-pin gold-plated detachable cable with ultra-low signal loss, wear-resistant construction, and easy replacement or upgrade down the road. Impedance is 20 ohm, the driver is dynamic, the shell is white, and it's a 3.5mm wired connection with push-button controls. KZA also lists a warranty. Note the variant name again: 3.5mm NO Mic — so plan on using your headset or motherboard mic for comms.
Buy it if you play FPS and tactical games seriously, want strong isolation in a noisy room, and prefer a wired, low-latency connection straight into your PC, console controller or phone.
Skip it if you want one pair for everything, or you need an inline mic for calls.
Side-by-Side: Which Should You Choose?
• Best for competitive gaming / positional audio → KZA COUSTICS Axas. Spatial tuning, deep seal, 10–20kHz range built around footstep detail.
• Best for noise isolation in a loud room → KZA COUSTICS Axas. Deep in-ear seal with three tip sizes plus AI noise cancellation for chat.
• Best for calls and voice chat on the cable → CCA KZ ZST X. It has a built-in HD mic; the Axas variant listed here does not.
• Best for long-session comfort → KZA COUSTICS Axas. Lightweight shell, S/M/L tips, explicitly designed to prevent wear fatigue.
• Best for cable upgradability → tie. Both use a 2-pin detachable, gold-plated design (0.75mm on the ZST X; 0.78mm/2-pin on the Axas).
• Best for plug-and-play across devices → tie. Both are 3.5mm wired, so they work with any standard headphone jack.
• Best all-rounder → CCA KZ ZST X. More versatile across music, media and casual games; the Axas is a specialist.
In my opinion, most people should buy the CCA KZ ZST X. It's the more complete earphone: hybrid drivers, a genuinely fun V-shaped tuning, a detachable silver-plated cable, and an inline mic for calls. If you game casually, you'll never feel short-changed.
But if gaming is the reason you're buying — FPS, tactical shooters, ranked play — I'd take the KZA COUSTICS Axas. The deep seal, spatial tuning and noise cancellation are exactly the things that make footsteps readable, and that's a specific job the ZST X wasn't built for. Pick based on which of those two people you actually are.
what is gaming earbuds
Gaming earbuds are in-ear monitors tuned and shaped for play rather than pure music listening. That usually means a deep in-ear seal for passive isolation, a frequency response that lifts positional cues like footsteps, and a wired connection to keep latency low. The KZA COUSTICS Axas is a textbook example; the CCA KZ ZST X is a music-first earphone that also works for games.
what is best gaming earbuds
There's no universal "best" — it depends on your priority. For competitive positional audio and isolation, the Axas is the stronger pick here thanks to its deep seal, spatial tuning and AI noise cancellation for voice chat. For someone who games casually but mainly listens to music, the ZST X's hybrid drivers and bass-forward tuning are the better fit. Match the earphone to your main use.
what gaming earbuds are good
Good gaming earbuds share a few traits: a secure, comfortable fit for long sessions, strong passive noise isolation, and a tuning that keeps directional detail audible. The Axas checks all three with its S/M/L silicone tips, deep seal and 10–20kHz range. The ZST X is good too, but its V-shaped bass boost is aimed at music enjoyment more than competitive clarity.
what is the best gaming earbuds for pc
For PC gaming specifically, the KZA COUSTICS Axas is my pick. A 3.5mm wired connection plugs straight into your motherboard or a controller, and the low-latency, noise-isolating design suits desktop play. Just remember the variant listed here has no inline mic, so you'll want a separate mic or headset for voice chat. The ZST X also works on PC and adds a built-in mic if that matters more to you.
