If you want a wired gaming earphone that works with practically anything you already own — PS5, Switch, PC, an older phone — choose Logicool G Hiarkio G333-BK; if you need a USB-C in-ear with customizable tuning and a wider frequency range for competitive mobile play, choose keephifi KZ EDZ Type-C.
• Logicool G Hiarkio G333-BK — biggest strength: a 3.5 mm jack plus an in-line volume control on the cable, so it plugs into consoles, PCs and phones without adapters, and you can adjust loudness without touching the device.
• Logicool G Hiarkio G333-BK — biggest trade-off: it's a plastic-and-aluminum 3.5 mm wired set with no detachable cable and no USB-C audio, so it's tied to devices that still have an analog jack.
• keephifi KZ EDZ Type-C — biggest strength: a detachable silver-plated Type-C cable with four color-coded tuning modes, so you can shift the sound toward bass or vocals without an external DAC.
• keephifi KZ EDZ Type-C — biggest trade-off: Type-C only, so anything without a USB-C audio port — most consoles, most desktops — simply can't drive it.
• Pick the Logicool G if you game across consoles and PC and want one cable that just works.
• Pick the KZ EDZ if you live on an Android phone or tablet and want to tweak your own sound signature.
The G333-BK is built around a simple idea: two dedicated audio drivers in each earpiece, one handling mid and treble, one handling bass. That's a genuine design choice in a market full of single-driver earphones, and it's the reason the set is positioned for immersion rather than flat monitoring. The 15 mm driver figure tells you the low end has some physical room to move, and the in-line microphone means chat and calls run through the same cable rather than a separate boom.
What stands out to me is the connectivity story. You get a 3.5 mm jack, and the listing pairs that with USB-C volume control — so the practical benefit is volume adjustment that doesn't require digging into a game menu. Plug it into a PS5 controller, a Switch, a PC, or a phone with a headphone jack and you're done. No dongles, no pairing, no battery to remember. At 19 g it's light enough to forget you're wearing it, and the included protective case means it survives a bag.
keephifi KZ EDZ Type-C: Who It's For
The KZ EDZ is a different animal. Its headline number is the 7 Hz–45,000 Hz frequency range, which is extraordinarily wide for an in-ear monitor and is the spec that underpins its claim of fast transient response. In practice, a wide range plus an extra-long excursion driver is the recipe for tight, immediate bass — the kind of low-end that makes footsteps and explosions read clearly rather than smearing together. The 24 ohm impedance and 107 dB sensitivity mean it's easy to drive straight from a phone or tablet without extra amplification, which matters if you're gaming on mobile.
The dual-damping system is the other half of the story. Its job is controlling sibilance — the harsh "sss" that makes long sessions fatiguing — so vocals stay smooth and instruments keep their character. If you've ever recorded or edited audio, that's the difference between a set you can wear for an hour and one you can wear all evening.
The feature I find most interesting is the detachable silver-plated Type-C cable with four color-coded tuning modes built into the filter. That's real flexibility: you can push bass for EDM or games, then flip to a vocal-forward signature for podcasts, all from the cable itself. The dual-mic setup and touch controls round it out, and a 1-year warranty is stated.
Who should buy it: Android and iPad users, PUBG Mobile and other mobile competitive players, and creators who want tuning control without buying a DAC. Who should skip it: console players, anyone on a device with only a 3.5 mm output, and anyone who dislikes touch controls and would rather have a physical volume wheel.
Side-by-Side: Which Should You Choose?
• Best for console gaming → Logicool G Hiarkio G333-BK. The 3.5 mm jack works with PS5, PS4 and Switch; the KZ EDZ's Type-C connection does not.
• Best for mobile-first, USB-C-only setups → keephifi KZ EDZ Type-C. It's designed around the port your phone actually has.
• Best for sound customization → keephifi KZ EDZ Type-C. Four tuning modes on the cable beat a fixed signature.
• Best for low-end impact and transient speed → keephifi KZ EDZ Type-C, on the strength of that 7 Hz–45,000 Hz range and long-excursion driver.
• Best for long, fatigue-free listening → keephifi KZ EDZ Type-C, which is explicitly engineered to tame sibilance.
• Best for simple volume control → Logicool G Hiarkio G333-BK. In-line control beats touch controls when your hands are busy.
• Best for travel and portability → Logicool G Hiarkio G333-BK. At 19 g with a protective case, it's the easier set to toss in a bag.
One honest caveat on both: neither is the right pick for someone who wants wireless freedom. Both are wired by design, and that's the trade-off you accept for zero-latency audio and no charging.
If I had to pick one for myself, I'd take the keephifi KZ EDZ Type-C — but only because my gaming happens on a phone and tablet. The tuning modes, the detachable cable, the wide frequency range and the damping system aimed at fatigue-free listening add up to a more adaptable set for a USB-C world, and I like being able to change the sound without buying anything else.
That said, if your gaming lives on a PS5, a Switch or a desktop PC, I'd point you the other way. The Logicool G Hiarkio G333-BK is the more universally compatible set, and its dual-driver design, in-line mic and physical volume control are exactly what a console player needs. Buy the KZ EDZ for flexibility; buy the G333-BK for compatibility. Check the current price on Amazon before you commit, since that's the one thing that can genuinely flip this decision.
The G333-BK. It uses a standard 3.5 mm jack that plugs into a PS5 controller, while the KZ EDZ uses a Type-C connection that console controllers don't provide for audio.
The listing describes Type-C compatibility aimed at Android, iPad and similar USB-C devices. A Lightning-based iPhone would need its own connection, so check your port before buying.
On paper, the KZ EDZ. Its stated 7 Hz–45,000 Hz range and extra-long excursion driver are specifically designed for tight, fast low-frequency response, and its cable tuning modes let you boost bass further. The G333-BK splits duties between two drivers, which favors overall immersion rather than maximum low-end.
Only if your PC has a USB-C audio port. The G333-BK is the safer choice for desktop use because a 3.5 mm jack is far more common on motherboards and front-panel outputs.
