If you want a warmer, bass-forward, feature-loaded IEM that doubles as a gaming and vocal set, choose keephifi KZ EDX Pro; if you need a neutral-leaning, metal-bodied monitoring earphone with a wider frequency ceiling and no microphone, choose Bawjog KZ ZVX Pro.
• keephifi KZ EDX Pro — biggest strength: A 10mm composite dynamic driver tuned for a warm, low-heavy signature, with a 10Hz low-end reach, a 5N OFC flat cable, and a microphone version available.
• keephifi KZ EDX Pro — biggest trade-off: The 20kHz top end is modest, the shell is resin with metal ornament rather than full metal, and the latest packaging ships with only one pair of ear tips.
• Bawjog KZ ZVX Pro — biggest strength: An inner-magnetic dynamic driver with a larger magnet and wider voice coil, an all-metal body, and a 20Hz–40kHz frequency range that reaches much higher than the EDX Pro.
• Bawjog KZ ZVX Pro — biggest trade-off: No microphone, no in-line remote beyond a push button, no noise cancellation, and a lower 105dB sensitivity that asks more of your source.
• Who the EDX Pro is for: Gamers, phone and MP3 listeners, and anyone who wants a mic, media controls, and a fun, bass-rich tuning.
• Who the ZVX Pro is for: Monitoring-minded listeners, musicians, and detail-chasers who want a metal build and don't need to take calls.
The EDX Pro is the more "daily driver" of the two. Its 10mm composite magnetic dynamic driver is tuned the popular, ACG-leaning way: the magnetic force is strong enough that low-frequency density goes up, which is exactly what makes electronic music and heavy instrumental tracks feel thick and physical. The stated low-frequency dive reaches 10Hz, and the 10Hz–20KHz range is paired with a 112dB sensitivity and 24-ohm impedance — figures that suggest it plays loud and easily off a plain phone jack.
What it does best is versatility in everyday situations. There's a microphone version, a standard wired remote with media controls, and passive noise cancellation, so it works for calls, mobile games, and casual listening without extra gear. The 0.75mm gold-plated 2-pin connector is the standard upgrade path, and the 5N OFC anaerobic copper flat cable is a genuinely nicer stock cable than most budget sets bother with — the flat profile also resists tangling. The resin cavity with metal ornament and UV-varnish finish comes in Classic Black, Cyan, and White.
Who should buy it: gamers who want a mic, students and commuters plugging straight into a phone or MP3 player, and anyone who values a warm, bass-heavy sound with a replaceable cable. Who should skip it: critical listeners chasing air and top-end extension, people who want a full-metal shell, and anyone who needs a second set of ear tips in the box — the current packaging includes only one pair.
The ZVX Pro is built around a different philosophy. Its inner-magnetic dynamic driver is described as having higher sensitivity and lower distortion than traditional drivers of the same size, helped by a larger magnet volume, a wider voice coil diameter, and a minimized magnetic gap. In plain terms, that's engineering aimed at cleaner transient response — sharper attack on plucks, hits, and drum edges — rather than at sheer low-end weight.
The frequency range tells the same story: 20Hz to 40kHz, which extends far past the EDX Pro's 20kHz ceiling. The 18-ohm impedance is low, but the 105dB sensitivity is lower than the EDX Pro's 112dB, so it will appreciate a bit more output from your source or a small DAC/amp. The 65g all-metal body gives it a denser, more premium feel, and the 0.75mm 2-pin replaceable cable is on board here too.
The catch is features. This is the Without Mic version — no microphone, no media remote beyond a push button, and no noise control at all. It's a listening tool, not a headset. Bawjog positions it for classical, jazz, rock, and pop alike, which fits a more neutral, monitoring-oriented tuning than the EDX Pro's warm tilt.
Who should buy it: musicians, monitoring users, and listeners who want a metal build, a wide frequency range, and low-distortion detail. Who should skip it: anyone who takes calls, plays voice-chat games, or wants passive noise cancellation.
• Best for gaming and voice chat → keephifi KZ EDX Pro. It's the only one of the two with a microphone option and media controls.
• Best for pure music monitoring → Bawjog KZ ZVX Pro. Its inner-magnetic driver, larger magnet, and wider voice coil target lower distortion and faster transients.
• Best for bass-heavy genres (electronic, heavy instrumental) → keephifi KZ EDX Pro. The 10Hz low-end reach and warm tuning are built for it.
• Best for top-end extension and air → Bawjog KZ ZVX Pro. 20Hz–40kHz versus the EDX Pro's 20Hz–20kHz.
• Best for easy driveability off a phone → keephifi KZ EDX Pro. 112dB sensitivity at 24 ohms is the more forgiving pairing.
• Best build feel in hand → Bawjog KZ ZVX Pro. All-metal enclosure versus a resin cavity with metal ornament.
• Best for calls, MP3 players, and Android phones → keephifi KZ EDX Pro. The mic is described as generally compatible with those devices.
• Best for cable upgraders → a tie. Both use the 0.75mm 2-pin standard, so either accepts an aftermarket cable.
• Best for classical and acoustic detail → Bawjog KZ ZVX Pro. Its stated design goal is accuracy across genres rather than a bass lift.
My Verdict
If I had to pick one for most people, I'd take the keephifi KZ EDX Pro. In my opinion it's the smarter all-rounder: the mic, media controls, passive noise cancellation, 112dB sensitivity, and warm tuning make it the set you can actually live with day to day — phone calls, games, commuting, all of it. The Bawjog KZ ZVX Pro is the better specialist, and I'd recommend it without hesitation to a musician or detail-focused listener who wants an all-metal monitoring earphone and never needs a mic. Two different jobs, two different answers — and that's the whole point.
They're tuned differently rather than one being objectively "better." The EDX Pro leans warm with elevated low frequencies; the ZVX Pro aims for lower distortion and a wider 20Hz–40kHz range. Pick by taste and use case.
No. The listed version is "Without Mic," with only a push button control and no noise cancellation. If you need calls or game chat, the EDX Pro with mic is the one to look at.
Yes. Both use a 0.75mm 2-pin connector, so you can swap in an upgraded cable — though any replacement cable is bought separately, not included.
I don't quote prices here, since they move around. Check the current price on Amazon for each, then weigh the EDX Pro's mic and controls against the ZVX Pro's metal build and wider frequency range for your own use.
