If you want a wired gaming headset that plugs into almost anything you own — console, PC, phone, even a Switch — choose Aitalk Gaming Earbuds; if you need a low-profile in-ear monitor built around a dual-driver HiFi sound signature for music first and gaming second, choose KZ Duet. Both are wired in-ear earbuds with a mic and a 3.5mm connection, so the real decision comes down to how you want to use them and what your devices can accept.
• Aitalk Gaming Earbuds — biggest strength: dual 3.5mm and USB-C plugs plus a full accessory bundle (three ear tip sizes, ear hooks, line clip, adapter), so it adapts to nearly any gaming setup.
• Aitalk Gaming Earbuds — biggest trade-off: the design leans entirely toward gaming and voice chat; the sound tuning is bass-forward and positional, not neutral.
• KZ Duet — biggest strength: a 10mm + 8mm dual-driver hybrid with a 20Hz–40,000Hz range and 110dB sensitivity, aimed at detailed, full-range audio rather than pure gaming cues.
• KZ Duet — biggest trade-off: it is 3.5mm only. If your device has no headphone jack, you need a separate adapter, and there is no bundled USB-C plug.
• Who Aitalk is for: console and PC players who want one cable that works everywhere and a secure, sport-friendly fit.
• Who KZ Duet is for: listeners who want a compact IEM for music, calls and casual gaming on anything with a 3.5mm jack.
The Aitalk Gaming Earbuds (model G20-Black) are built around one idea: get a wired connection into as many devices as possible. The package includes a 3.5mm plug and a USB-C adapter plug, so the same pair covers a PlayStation 5, PS4, Xbox Series X, Nintendo Switch, PC, laptop, tablet, iPad, iPhone or Android phone. That flexibility is the whole point. You are not hunting for a dongle every time you switch from the couch to the desk.
The audio side is tuned for games. Aitalk uses a 10mm dynamic driver with a 16-ohm impedance and a 20Hz–20,000Hz range, and the marketing angle is footstep enhancement plus 360-degree positional cues. I would treat that as a design intent rather than a promise — what the specs tell you is a low-impedance, easy-to-drive in-ear with boosted bass and a two-tone cavity meant to separate lows, mids and highs. For spotting direction in a shooter and hearing chat clearly, that is a sensible tuning.
Comfort is the other selling point, and the parts list backs it up: a 45-degree oblique earplug angle, three sizes of soft silicone tips, ear hooks, and a magnetic design so you can hang the buds around your neck when you pull them out. Aitalk also claims up to 93% noise isolation with the memory foam tips and lists a 3.9-foot anti-tangle cable. The in-line control handles volume, chat and phone calls.
Who should buy it: console and PC gamers who want one wired set for everything, people with smaller ears who struggle with bulky headsets, and anyone who wants ear hooks for workouts or sleep. Who should skip it: listeners chasing neutral, detailed music reproduction, and anyone whose main device is a phone with no headphone jack and no interest in carrying the adapter.
The KZ Duet takes a different route. Where Aitalk spreads its bets across connectivity, KZ concentrates on the driver and the sound. The Duet is a hybrid: a 10mm driver paired with an 8mm driver, listed as a hybrid driver type with a 20Hz–40,000Hz frequency range, 25-ohm impedance and 110dB sensitivity. That extended top end and high sensitivity matter — the Duet should get loud easily and render upper frequencies that a single 20kHz-limited driver simply cannot reach on paper.
KZ also specifies 36dB of noise isolation and a 0.01-millisecond latency figure for the wired connection. The latency number is the honest argument for wired over Bluetooth in gaming, though at that scale it is effectively negligible either way. The housing is metal and plastic with an oblique-angled fit and two sets of ear tips, so the fit strategy is similar to Aitalk but with fewer sizes in the box.
The microphone setup is dual omnidirectional condenser mics with an in-line button for play/pause, answer/end and voice assistant. That is a call-and-commute feature set more than a tournament one. KZ also notes the Duet can pair with a compatible Bluetooth adapter (AZ09 Pro or AZ20) if you want to go wireless later — but that adapter is not included, so treat the Duet as a 3.5mm wired earphone out of the box.
Who should buy it: music listeners who want a compact IEM with a genuinely wide frequency range, travelers and commuters using 3.5mm devices, and gamers who want clean audio and clear mic pickup without a bulky headset. Who should skip it: anyone on a USB-C-only phone or a console without a headphone jack, unless they are willing to add an adapter.
Side-by-Side: Which Should You Choose?
• Best for music detail and top-end extension → KZ Duet. The 20Hz–40,000Hz hybrid range is wider than Aitalk's 20Hz–20,000Hz.
• Best for fit options out of the box → Aitalk Gaming Earbuds. Three tip sizes plus ear hooks versus KZ's two tip sizes.
• Best for easy volume and chat control on console → Aitalk Gaming Earbuds. Dedicated in-line volume control and a slim mic built for game chat.
• Best for low-profile everyday carry → KZ Duet. Metal-and-plastic housing, no adapters to keep track of.
• Best for workout and sleep use → Aitalk Gaming Earbuds. Ear hooks and a magnetic neck-hang design are aimed squarely at movement.
• Best for impedance matching with weak sources → Aitalk Gaming Earbuds. At 16 ohms it is easier to drive than the Duet's 25 ohms.
• Best for future wireless use → KZ Duet. It is listed as compatible with KZ's Bluetooth adapters, though you buy those separately.
In my opinion, the Aitalk Gaming Earbuds are the safer buy for most people reading this. The dual 3.5mm and USB-C plugs mean it works with whatever you already own, the three tip sizes and ear hooks solve the fit problem that kills most in-ear purchases, and the tuning is aimed at exactly what gamers want: positional cues, bass and clear chat. The KZ Duet is the better earphone if music is your priority — that hybrid driver and 40kHz range are real advantages — but it asks you to already have a 3.5mm jack and to bring your own adapter if you don't. If you want one wired pair that covers gaming, calls and workouts without fuss, I would take the Aitalk.
FAQ
how to put in ear earbuds
how to fit in ear earbuds
The seal is everything — a loose tip loses bass and lets outside noise in. Try every included size: Aitalk ships three silicone sizes plus ear hooks, and the KZ Duet includes two sets of tips. If sound feels thin or the bud keeps slipping, you have the wrong size, not a bad earphone.
how to clean in ear earbuds
Wipe the silicone tips with a damp cloth or a little isopropyl alcohol, and pull them off periodically to clear wax from the nozzle. Never run water through the housing itself. The Aitalk's detachable tips and the KZ Duet's replaceable cushions both make this a quick routine rather than a chore.
how to ear earbuds
If you mean how to wear them so they stay put, use the hooks. Aitalk includes ear hooks and a magnetic neck-hang design so the buds dangle instead of dropping when you pull them out. The KZ Duet relies on its angled fit alone, which is fine for desk use but less secure during hard workouts.
