How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
If you want a gaming-first wired earphone with an in-line mic and console-friendly controls, choose Logicool G Hiarkio G333-BK; if you need a tuneable, audiophile-leaning IEM with a replaceable cable for music, monitoring and gaming, choose keephifi KZ EDX Pro.
• Logicool G Hiarkio G333-BK — biggest strength: a gaming-focused design with a 15 mm dual-driver setup, an in-line microphone for chat, and volume control, plus PS5/PS4/Switch/PC/smartphone compatibility through a 3.5 mm jack.
• Logicool G Hiarkio G333-BK — biggest trade-off: the cable is fixed, there is no stated upgrade path, and the feature set is about convenience and communication rather than tuning flexibility.
• keephifi KZ EDX Pro — biggest strength: a 10 mm composite dynamic driver with a 10Hz–20KHz range, a 2-pin 0.75 mm gold-plated connector and a 5N OFC flat cable you can swap out — an IEM built around sound and upgradability.
• keephifi KZ EDX Pro — biggest trade-off: it ships in a "no Mic" style and the noise control field is listed as None, so call and chat duties are not its focus, and you get a single pair of ear tips with the current packaging.
• Who each pick is for: pick the Logicool G if you mainly play on console or PC and talk while you play; pick the KZ EDX Pro if you want the most sound-per-dollar flexibility for music, monitoring and gaming on a wired 3.5 mm connection.
The G333-BK is a wired, in-ear gaming earphone from Logicool G, and it is designed around one clear idea: keep you connected to your game and to your teammates at the same time. It uses dual audio drivers — two dedicated drivers handling mids, treble and bass — which is the kind of setup aimed at separating footsteps, gunfire and voice chat instead of just playing a wall of sound. The 15 mm driver size is unusually large for an in-ear design, and combined with the in-line microphone it points to a product meant to be worn for long sessions while you talk.
The practical side is where it earns its place. A 3.5 mm jack plus stated compatibility with PS5, PS4, Switch, PC and smartphones means one pair of earphones can move between your console, your laptop and your phone without adapters or pairing. Volume control is built in, so you are not reaching for a controller or keyboard mid-match. The plastic-and-aluminum enclosure keeps it light — 19 g — and it comes with a protective case, which matters if you are the type to throw earphones in a bag between sessions.
keephifi KZ EDX Pro: Who It's For
The KZ EDX Pro is an in-ear monitor in the classic budget-audiophile sense, and its spec sheet reads like one. A 10 mm composite magnetic dynamic driver, a frequency range of 10Hz–20KHz, 24 ohm impedance and 112 dB sensitivity — that combination is easy to drive from a phone or a controller's headphone jack while still leaving headroom for a dedicated DAC later. The tuning is described as popular and ACG-oriented, with a low-frequency that dives to 10Hz and a dense, weighty bass character that suits electronic and heavy instrumental music, while the transient response is quick enough for vocals and classical detail.
What really separates it from the Logicool G is the hardware philosophy. The cable is a 5N OFC anaerobic copper flat cable with a 0.75 mm standard gold-plated 2-pin connector, which means you can detach it and try an upgraded cable later (sold separately) — a hobby-friendly design that no fixed-cable earphone can match. The shell is skin-friendly imported resin, high-temperature molded and UV-varnished, with a metal ornament, and it comes in Classic Black, Cyan and White. The ear-hook shape helps it stay put during long listening sessions or on stage.
The trade-offs are real, though. The listing style is "no Mic," and noise control is listed as None, so you should not count on it for voice chat on a console. The current packaging includes one pair of ear tips, and the brand notes its older bundle is effectively gone. It also lists Bluetooth under wireless technology, but the connection is a wired QDC 3.5 mm plug, so treat it as a wired IEM. I recommend the EDX Pro for musicians, singers, audiophiles and gamers who care most about sound quality, isolation from the fit, and the freedom to upgrade the cable.
• Best for voice chat and in-game comms → Logicool G Hiarkio G333-BK (in-line microphone plus in-line volume control; the KZ EDX Pro is a "no Mic" style with noise control listed as None).
• Best for console convenience → Logicool G Hiarkio G333-BK (stated PS5, PS4 and Switch compatibility on a single 3.5 mm jack, so it moves between systems without fuss).
• Best for pure sound quality and tuning character → keephifi KZ EDX Pro (10 mm composite dynamic driver, 10Hz–20KHz, bass-forward ACG tuning with quick transients).
• Best for upgradability → keephifi KZ EDX Pro (0.75 mm gold-plated 2-pin connector and a 5N OFC flat cable you can replace).
• Best for long listening or stage use → keephifi KZ EDX Pro (ear-hook shape, resin shell, 24 ohm / 112 dB so it runs off almost anything).
• Best for travel and storage → Logicool G Hiarkio G333-BK (19 g and a protective case included).
• Best for driving from a phone or controller → keephifi KZ EDX Pro (low impedance and high sensitivity; a DAC is optional, not required).
• Best for brand-ecosystem players → Logicool G Hiarkio G333-BK (Logicool G's gaming-focused design language and device compatibility).
In my opinion, the right answer depends entirely on whether you talk while you play. If your sessions are on a PS5, Switch or PC and you are in party chat, I would buy the Logicool G Hiarkio G333-BK — the microphone, the volume control on the cable and the broad device compatibility solve the exact problems a gaming earphone should solve, and the protective case makes it easy to carry.
If you are buying for music, monitoring or solo gaming where sound quality matters more than a mic, I would buy the keephifi KZ EDX Pro. Its 10 mm dynamic driver, 10Hz–20KHz range and swappable 2-pin cable give you a headphone you can grow with, and the resin shell and ear-hook fit suit long listening sessions. Neither is a compromise pick — they are simply aimed at different buyers.
The Logicool G G333-BK is the better fit for PS5 because it is explicitly listed as compatible with PS5, PS4, Switch, PC and smartphones, and it includes an in-line microphone and volume control. The KZ EDX Pro is wired via a 3.5 mm jack too, but it is sold in a "no Mic" style, so chat is not its strength.
The listing style is "no Mic," and noise control is listed as None, so you should not expect voice chat support. It is best treated as a wired in-ear monitor for music, monitoring and solo gaming rather than a headset replacement.
Yes. It uses a 0.75 mm standard gold-plated 2-pin connector with a 5N OFC flat cable, so you can swap in an upgraded cable (sold separately) later. The Logicool G G333-BK's cable is not described as replaceable, so this is a clear advantage for the KZ.
The keephifi KZ EDX Pro, in my opinion. Its 10 mm composite dynamic driver, 10Hz–20KHz frequency range, 24 ohm impedance and 112 dB sensitivity are built around music reproduction, and the bass-forward ACG-oriented tuning suits electronic and instrumental tracks well. Check the current price on Amazon before deciding, since it is the more specialised of the two.
