Yinyoo CCZ NC02 10mm in-ear monitors with detachable 2-pin cable (wired gaming & music IEMs)
Product description
The essentials
If you want lightweight in-ear monitors that stay put while you’re moving, the Yinyoo CCZ NC02 is built around that exact idea. On paper, they’re designed to be comfy for long sessions (the earbuds are listed at just 3.5 grams each) and secure thanks to an ergonomic shape with ear hooks. That combination matters if you’re picking up something for gym days, commuting, or simply wearing earbuds for hours without constantly readjusting them.
They’re also aimed at wired listeners: you get 10mm magnetic dynamic drivers for a dynamic HiFi-style sound, and the tuning focus (as described) is on pop and rock, with clear vocals and bass presence. It’s not the sort of set that’s trying to be everything to everyone, but for a budget-friendly wired IEM approach, it has a lot of practical boxes ticked.
There’s also a bit of studio-style thinking here: a 5N silver-plated copper cable with shielding fabric is mentioned, plus a detachable 2-pin TFZ connector. The result is a pair of earbuds that can fit both gaming and everyday music, as long as you’re happy using a 3.5mm cable.
What you’ll notice day to day
The biggest day-to-day factor is comfort and fit. The CCZ NC02 uses a noise-isolating design (passive, meaning it reduces ambient sound rather than actively cancelling it) and the ear hooks are there to keep the monitors secure for sports and daily use. If you’ve ever had earbuds slowly creep out during a brisk walk, this is the type of design you’d choose specifically to avoid that hassle.
For sound, the 10mm composite magnet dynamic driver is pitched as delivering rich bass and clear vocal reproduction. The description also mentions a single-diaphragm approach to help minimise frequency distortion, which is a polite way of saying the tuning should stay coherent rather than sounding “rough” at higher volume. You’re also given a frequency response of 20–20,000 Hertz and 16 Ohms impedance, which helps frame what kind of load these are in.
One more practical point: they’re designed for pop and rock, so if your library is mostly heavy on modern electronic sub-bass or very vocal-heavy mixes, you’ll likely find them a decent match for the way they’re described. It’s not perfect though—if you want deep sub-bass slam or the kind of soundstage you’d associate with pricier audiophile sets, budget wired IEMs like these can feel a little limited.
Key features that matter for gaming and music
The CCZ NC02 stays in the wired lane, and that’s actually a strength if you want predictable latency and a straightforward setup for consoles/PC and phones with a 3.5mm jack. The cable is described as optimised for 3.5mm audio sources and is said to be compatible with PC, smartphone or console setups (as long as the device has the right 3.5mm input).
The detachable cable system is useful in real life, not just on spec sheets. If the cable gets damaged through wear and tear, or you want to swap in an alternative later, 2-pin detachable connectors can be a big deal for longevity.
There’s also an optional microphone mentioned, which makes this less of a “music-only” purchase. That said, it’s worth bearing in mind that the inclusion of a microphone can vary by bundle—so if calls matter to you, it’s a good idea to double-check what’s in the actual box listing.
Tech specs (the ones to sanity-check)
- Driver size: 10mm composite magnet dynamic driver
- Connector type: TFZ 2-pin detachable cable
- Cable: 5N silver-plated copper (shielding fabric mentioned)
- Frequency response: 20–20,000 Hertz
- Impedance: 16 Ohms
- Sensitivity: 105 decibel (as stated)
- Wired connection: 3.5mm audio jack
- Noise reduction: passive noise isolation (ambient noise reduction)
If you’re sensitive to impedance and volume matching, 16 Ohms is fairly approachable for many devices, but output levels vary a lot between phones, controllers, and laptops. So it’s sensible to expect “works with most common sources” rather than assuming it’ll be equally loud everywhere.
Where it shines, and where it may fall short
It makes sense if you want: - Lightweight in-ear monitors for gym, travel and everyday listening. - A secure fit approach using ergonomic ear hooks. - A wired 3.5mm set for gaming and music that’s easy to plug in. - A detachable cable setup (useful if cables take the most punishment).
You may want to skip it if: - You’re looking for active noise cancelling (it’s passive noise-isolating by description). - You need a fully wireless, charging-free experience. - You’re chasing the very top end of soundstage and refinement you’d expect from higher-priced IEMs.
One small limitation to keep in mind: the description flags a tuning focus on pop and rock, so if you mainly listen to genres outside that (or you’re very particular about treble sparkle versus smoothness), you might find a different tuning suits you better.
What’s included, and what to check before buying
The description mentions an optional microphone and TFZ detachable cable, but the exact “in the box” list isn’t provided here. Before you commit, it’s worth checking the listing details for:
- Whether a microphone is included in your specific bundle.
- The exact cable length/termination options shown for the 3.5mm plug.
- Whether the ear tips provided are a good match for your ears (fit affects comfort and bass impact more than people expect).
Also, since it’s described for 3.5mm sources, make sure your gaming device/controller/phone actually has a 3.5mm jack. Many modern devices don’t, so you may need an adapter—only you’ll know what you already use.
Final verdict
It’s a solid buy if you’re after lightweight wired in-ear monitors with a secure, hook-based fit and a detachable 2-pin cable design—especially for commuting, fitness, gaming, and casual listening on 3.5mm devices. The 10mm driver spec and passive noise isolation positioning suggest it’s aiming to be a comfortable, clear-sounding everyday set rather than a heavyweight audiophile project.
However, it’s not the best choice if you specifically want active noise cancelling or a wireless experience, and it may feel a bit constrained if you’re expecting “premium IEM” sound performance in every detail. For most people buying in the budget wired IEM category, though, the CCZ NC02 reads like a practical, no-nonsense option.

They use passive noise isolation, which reduces some ambient sound, but they’re not described as having active noise cancelling.
Do they work with a PC and console?
They’re described as compatible with 3.5mm audio sources, including PC, smartphone and console setups, assuming your device has the right 3.5mm input.
Is the cable detachable?
Yes—there’s a TFZ 2-pin detachable cable mentioned, which is usually helpful for durability and replacements.
Is there a microphone?
An optional microphone is mentioned, but the exact inclusion can depend on the bundle—check the listing details if you’ll use it for calls or in-game chat.
