CCA ZAS

The CCA ZAS delivers 99th percentile sound quality with a 10mm dynamic driver and seven balanced armatures, all for around $78 USD. It's a wired IEM that punches way above its price class for music and gaming, with owners saying it beats pricier options like the Shure SE215. But build quality and user sentiment are both below average, so durability and fit are real gambles. Buy it for the sound if you don't mind the rough edges.

Let's talk about what those seven balanced armatures actually do for you. The ZAS uses six 50024s BAs plus a single 30019 BA, and the result is a sound signature that's crisp, sharp, and incredibly revealing. The 10mm dynamic driver handles the low end, and it does a solid job of keeping bass present without muddying up the midrange. The frequency response goes from 10Hz all the way up to 40kHz, which is well beyond what most humans can hear, but it tells you the drivers are capable of serious extension. In practical terms, instrument separation is excellent. You can pick out individual guitar lines, backing vocals, and subtle reverb tails that cheaper IEMs just smear together.

The 24Ω impedance and 109dB sensitivity mean these are easy to drive from just about anything. A phone dongle, a laptop headphone jack, a Nintendo Switch, whatever. You don't need a beefy amp to get them loud. That's a real advantage for a budget IEM, because it means you're not forced into buying extra gear just to make them usable. The sound score in our database is the best we've seen for this category, and it's not close. But that performance comes with a caveat. A few owners have mentioned that the tuning isn't for everyone, and some folks find the highs a little too aggressive without EQ. If you're sensitive to treble, you might want to plan on some equalizer tweaking.

Stacked against the usual suspects, the ZAS occupies a weird and interesting niche. The Apple AirPods Pro 3rd Generation and Samsung Galaxy Buds3 Pro are wireless, have active noise cancellation, and are far more convenient for daily use. But they also cost significantly more, and their sound quality, while good, doesn't touch what the ZAS does in terms of raw detail and separation. The Nothing Buds 2 and Sony WF-C700N are closer in spirit to the ZAS as budget-friendly options, but they're still wireless and prioritize convenience over pure audio fidelity. The ZAS is the only one here that's wired, which means no battery anxiety, no latency issues for gaming, and no codec compression.

The trade-off is obvious. You give up ANC, wireless freedom, and a polished companion app. You also give up the kind of build quality and consistency that Samsung and Apple deliver. The Soundcore P31i is probably the closest competitor in terms of price, and it offers a more reliable ownership experience with decent sound. But it can't match the ZAS for sheer audio performance. If you want the best sound for the least money and don't care about wires, the ZAS wins. If you want a dependable daily driver, any of the wireless options are safer bets.

The ZAS is priced at $78 USD in the US, and around €94-95 in Europe. For that money, you're getting a driver configuration that would normally cost you two or three times as much from a bigger brand. The value proposition is genuinely strong if you're buying these purely for sound quality. Multiple owners have directly compared them to the Shure SE215, which costs more, and said the ZAS comes out ahead in clarity and balance. That's not nothing.

But value isn't just about the sticker price. The durability concerns mean you might be buying a second pair sooner than you'd like. And if you end up needing to replace the cable or add a Bluetooth module, that's extra cost on top. Still, for a budget audiophile or a gamer who wants competitive audio without spending $150+, the ZAS is hard to beat on pure performance per dollar. Just know that you're rolling the dice on quality control.

The CCA ZAS is one of those products that makes you do a double take when you look at the spec sheet. You're getting a hybrid setup with a 10mm dynamic driver and seven balanced armatures, all stuffed into a metal and resin shell. That's the kind of driver count you'd normally associate with IEMs costing several times more. And the sound score in our database backs it up, landing in the 99th percentile. This thing is an absolute monster for detail retrieval at this price point.

Who is this for? Honestly, it's for the tinkerer. The person who doesn't mind a wired connection, who might already own a DAC or a decent dongle, and who wants to hear every little texture in their music without selling a kidney. It's also a solid pick for gamers on a budget who want to pinpoint footsteps without buying a dedicated gaming headset. The detachable 2-pin cable means you can swap in a Bluetooth module or a nicer cable later, which is a nice bit of future-proofing.

But here's the thing. The user sentiment score is only in the 33rd percentile, and the build quality sits at the 34th. So while the sound is top-tier, the ownership experience is a bit of a gamble. You're getting flagship-level audio performance wrapped in a package that sometimes feels like it was assembled in a hurry. If you're okay with that trade-off, the ZAS is a genuinely exciting buy. If you want something that just works out of the box with zero fuss, keep scrolling.

If you need a reliable pair of earphones for daily commuting, work calls, or just something you can toss in a bag without worrying about it, the ZAS is not for you. The build quality is below average, and the mic is mediocre at best. You'd be better off with something like the Soundcore P31i or Sony WF-C700N, which offer a more consistent ownership experience with wireless convenience and better call quality.

Also skip these if you're sensitive to treble or prefer a warmer, more relaxed sound signature. The ZAS is tuned to be revealing and crisp, which some listeners find harsh without EQ. If you want something smooth and easy to listen to for hours, look at a single dynamic driver IEM instead. And if you've never used wired earphones before and don't want to deal with cables, dongles, or EQ tweaking, just get a decent pair of wireless buds and call it a day.

For the budget audiophile who already owns a decent source and doesn't mind a wire, the ZAS is a no-brainer. The sound quality is genuinely exceptional for the price, and the detachable cable means you can experiment with upgrades or go wireless later. Gamers on a budget will also find a lot to like here, especially if they're willing to spend a few minutes with an equalizer to tame the highs. The instrument separation makes it easy to track positional audio cues.

But if you're buying your first pair of nice earphones and you want something that just works, the ZAS might frustrate you. The fit isn't universal, the build quality is inconsistent, and the mic is mediocre at best. If you need something for calls or daily commuting, look elsewhere. The ZAS is a specialist's tool, not an all-rounder. Buy it for the sound, and accept the rough edges.
