How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
If you want a wired IEM that's easy to drive straight from a phone and leans into warm, bass-forward musicality, choose senleeor KZ EDX PRO; if you need a gaming-first in-ear with an inline mic, push-button controls and a wider, more open soundstage, choose Jacuate IEM Earbuds.
• senleeor KZ EDX PRO — biggest strength: A 10mm dual magnetic circuit dynamic driver with an integrated electronic crossover board, tuned for strong low-frequency output and lively vocals, in a lightweight resin-shell, over-ear-hook design that stays put for long sessions.
• senleeor KZ EDX PRO — biggest trade-off: It's a pure music-first earphone. There's no mention of an inline mic on every version, no push-button control module, and no gaming or communication features — the mic is listed as optional.
• Jacuate IEM Earbuds — biggest strength: Built for gaming and voice. A semi-open rear cavity widens the soundstage for positional cues, and the omnidirectional HD mic with noise cancellation plus in-line controls handle calls, chat and track control without touching your device.
• Jacuate IEM Earbuds — biggest trade-off: With a 16Ω impedance and no isolation-style noise control listed, it's less about blocking the world out — it's about hearing your game and your teammates clearly.
• Pick senleeor KZ EDX PRO if you mainly listen to music and want a comfortable, low-impedance wired IEM you can plug into a phone.
• Pick Jacuate IEM Earbuds if you game, take calls, or need mic-and-button convenience on the cable.
The KZ EDX PRO is an upgrade of the KZ EDX, and the spec sheet makes its priorities obvious. The centerpiece is a single 10mm dual magnetic circuit dynamic driver. Two magnetic circuits rather than one means more magnetic force driving the diaphragm, and senleeor's own framing is that this produces a more natural low-frequency response with transparent highs. The electronic crossover board is integrated into the driver itself to widen the low-mid dynamic range. In plain terms: this is a tuning built to make bass feel full and vocals feel sweet, whether you're playing EDM, rock, R&B or a classical violin piece.
Ergonomics get real attention here too. The cavity uses an angular, hook-around-the-ear shape, and the housing is a lightweight resin build with PU ear hooks that spread pressure instead of concentrating it. If you've ever had an IEM go slack after twenty minutes, that over-ear hook path is the fix. The whole thing weighs about 0.05 kg, so it disappears on your head.
Then there's driveability, which is where this thing quietly wins a lot of arguments. At 24Ω impedance and 112dB/mW sensitivity, it's designed to run directly off a phone with no amplifier. Plug it into a 3.5mm jack and go. The cable is a detachable OFC wire with a 0.75mm Type-C pin connection and a straight 3.5mm plug, 1.25m long — long enough to pocket your phone or set it on a desk. It comes in Clear, Black or Cyan, with a one-year warranty.
Jacuate IEM Earbuds: Who It's For
The Jacuate S28 reads like a product designed around one question: what does a gamer actually need in their ears? The answer starts with the semi-open rear cavity, which is a deliberate acoustic choice. A sealed shell traps air and can narrow the perceived stage; a semi-open one lets it breathe, and Jacuate pairs that with grooved ear caps and short sound tubes that reduce audio loss. The result the company is chasing is positional clarity — footsteps, reloads, directional cues — which is exactly what competitive play rewards.
The microphone story is the other half. There's an omnidirectional HD mic with noise cancellation, positioned in-line just below the jaw so it picks up your voice rather than your room. The in-line module also carries push-button controls for call answer/end, play/pause/skip and volume. If you're the person who's always muting a Discord call or skipping a track mid-match, having that on the cable is a genuine quality-of-life upgrade over reaching for your keyboard or phone.
Build-wise, the Jacuate goes metal where the KZ goes resin. CD-textured metal faceplates, TPE ear tips and a soft ear fin for stability — it's a lighter-feeling, more jewelry-like object at 16 g. The driver is a 10mm dynamic unit with a stated 20Hz–20,000Hz frequency range and a low 16Ω impedance, so it's even easier to drive than the KZ. Connectivity is a 3.5mm jack plus USB-C, and Bluetooth is listed as a wireless technology on the spec sheet — worth verifying against your specific device expectations before you buy, since the product is fundamentally a wired IEM. It ships with cable, ear tip, manual and the earbuds themselves, and carries a two-year manufacturer warranty.
Who should buy it: gamers, streamers, singers and musicians who need a mic and controls on the cable, plus anyone who wants a wider stage and a metal-faced build. Who should skip it: listeners who want maximum isolation from a sealed fit, and anyone who prefers the simpler, music-tuned warmth of a dual-magnetic driver.
• Best for music-first listening → senleeor KZ EDX PRO. The dual magnetic circuit driver and integrated crossover are tuned around bass weight, vocal sweetness and a wide genre range, from EDM to classical.
• Best for gaming and voice chat → Jacuate IEM Earbuds. The semi-open cavity, positional tuning and omnidirectional noise-cancelling mic are purpose-built for in-game audio and comms.
• Best for plugging straight into a phone with no amp → both, but Jacuate edges it. The KZ at 24Ω/112dB is explicitly designed to run off a phone; the Jacuate is even lower at 16Ω.
• Most comfortable for hours-long fit → senleeor KZ EDX PRO. Resin housing, PU over-ear hooks and a 0.05 kg total weight are built around pressure-free long wear.
• Most convenient cable controls → Jacuate IEM Earbuds. Push-button in-line controls for calls, playback and volume, versus a media control touch setup on the KZ.
• Best build materials and warranty → Jacuate IEM Earbuds. Metal and TPE construction with a two-year manufacturer warranty, against the KZ's resin shell and one-year warranty.
• Best soundstage width for immersion → Jacuate IEM Earbuds. The tuned semi-open rear cavity and grooved ear caps are specifically aimed at stage expansion.
• Best for a detachable-cable setup on a music rig → senleeor KZ EDX PRO. The 0.75mm Type-C pin detachable OFC cable makes swapping or replacing the wire straightforward.
If I had to pick one for myself, I'd take the senleeor KZ EDX PRO. My reasoning is simple: I listen to music far more than I game, and the dual magnetic 10mm driver with its integrated crossover is aimed squarely at the thing I care about — full low end and clean vocals — while the 24Ω impedance means my phone alone can drive it. In my opinion, it's the better all-day music companion, and the over-ear hook fit is the kind of detail you appreciate after hour three. I'd recommend the Jacuate S28 instead if your ears spend more time in a lobby than in a playlist, because that mic and control module earn their place the moment you need to talk mid-match.
FAQ
It can play game audio well — the low-frequency tuning gives explosions and engines real weight — and the over-ear fit stays secure. But it lacks the Jacuate's positional-stage tuning and always-on inline mic, so it's a music earphone that happens to game, not a gaming earphone.
Yes. It uses an omnidirectional HD mic with noise cancellation, mounted in-line just below the jaw, and the same in-line module carries push-button controls for calls, playback and volume. The KZ EDX PRO lists its microphone as optional, so check the exact variant you're buying.
Both are designed to run unamped. The Jacuate is rated at 16Ω and the KZ EDX PRO at 24Ω with 112dB/mW sensitivity, which senleeor describes as easy to push from a phone. Neither needs an external amplifier.
On paper, the KZ EDX PRO is built for it: a lightweight 0.05 kg resin shell, an ergonomic angular cavity and PU ear hooks that reduce pressure. The Jacuate counters with a lighter 16 g body, soft TPE tips and an ear fin, so it's comfortable too — the KZ's over-ear hook path is simply the more secure of the two designs.
I don't quote prices here, since they change often. Check the current price on Amazon for both and weigh it against what you actually need: music tuning and long-wear comfort on one side, mic-and-control gaming convenience on the other.
