KZ ZSN PRO X
Its hybrid 10mm dynamic driver and balanced armature deliver a 7Hz–40kHz frequency response from a rugged zinc alloy and resin shell. The detachable cable with protected pins adds long-term durability and an in-line noise-cancelling microphone handles game chat clearly. These wired IEMs suit budget-focused gamers and music listeners wanting detailed, bass-forward sound at a desk rather than on a commute.

The 30-Second Version
The KZ ZSN PRO X is the $25 IEM that embarrasses earbuds four times the price. Grab some foam tips, plug in, and thank us later.
Overview
The KZ ZSN PRO X is the budget IEM that laughs in the face of most wireless earbuds under $100. For around $25, you're getting a hybrid driver setup with a 10mm dynamic and a balanced armature that churns out sound so detailed and bass-heavy, you'll wonder why you ever spent more. It's wired, so no ANC or fancy app tricks here. But if you care about pure audio quality per dollar, this is the one to beat. Just know the stock ear tips are trash and you might hear a faint hiss with some sources.
Performance
What shocked us was how well these handle bass without turning everything into mud. The dynamic driver hits hard but keeps control, while the BA tweeter pulls out background details you'd miss on most $50 buds - hi-hats, room reverb, little vocal textures. But the treble can get peaky; cymbals and sibilants sometimes stab a little too aggressively. And that hiss? It's real, especially plugged into a noisy laptop jack. A cheap USB-C dongle fixes it, but still, it's a flaw you'll notice in quiet tracks.
Pros & Cons
Pros
- Incredible detail and bass for under $30 99th
- Detachable cable makes it tough to kill for good 92th
- Comfortable and lightweight enough for hours of use 79th
- Shockingly good microphone quality for calls 70th
Cons
- Treble spikes can make long listening sessions fatiguing 30th
- Slight background hiss with many sources
- Ear tips crack easily and the paint wears off fast
- Cable connection gets loose over time on some units

Value & Pricing
Absolutely worth it. With stores flinging these around for as low as $24 (ignore the joker listing them for $15,161, that's a marketplace glitch), the KZ ZSN PRO X is one of the best audio values on the planet. Snag a pair, toss the stock tips, and for the cost of a pizza you'll have sound that legitimately competes with $100+ IEMs.
vs Competition
Most buyers at this price are cross-shopping wireless buds like the TOZO Crystal Pods or Soundcore P31i. Both give you Bluetooth freedom and decent sound, but neither comes close to the KZ for raw detail, bass texture, or soundstage. The trade-off is obvious: a wire. If convenience is king, get the Soundcore. If you want to hear what your music actually sounds like, the KZ smokes them. Even the pricier Samsung Galaxy Buds3 Pro can't match the immaculate separation on offer here, though they obliterate the KZ on features and ANC.

Common Questions
Q: Do these need a headphone amp?
Nope, they run fine straight from a phone or laptop thanks to the 25Ω impedance. But plugging them into a cheap USB-C dongle (like the Apple one) cleans up the hiss and gives you more volume headroom.
Q: Is the hissing sound a defect?
Not exactly. Sensitive IEMs often pick up background noise from weak headphone jacks. A dongle DAC usually kills it dead. If you still hear it, try a different source first before returning them.
Q: How long do they last?
The metal and resin body holds up okay, but the paint will wear off and the cable might get looser over a year of daily abuse. Good news: a replacement cable costs a few bucks, so you can keep them going for ages.
Who Should Skip This
If you hate wires or need ANC for commuting, look elsewhere. Grab the EarFun Air Pro 4+ for a solid wireless experience. Also, if you're treble-sensitive, these might fatigue you; the Moondrop Chu offers a smoother, less aggressive signature for about the same money.
Verdict
Buy it. For the price of a few cups of coffee, the KZ ZSN PRO X delivers sound quality that'll make you reconsider every other audio purchase. Yes, the build has some cheap spots and the highs can be sharp, but all that fades the moment you hear the first track. If you're okay with a wire and don't mind swapping ear tips, there's nothing close to this good under $50.
