Yinyoo CCZ BC04 PRO in Ear Monitor Headphone Review
The Yinyoo CCZ BC04 Pro IEMs deliver shockingly good sound and an elite-tier microphone for just $23. If you game on a budget, this might be the only headset you ever need to buy.
The 30-Second Version
For twenty-three dollars, this is a no-brainer for gamers and anyone needing a great mic on a budget. You're getting $80 sound and call quality in a package that just happens to feel like it costs twenty-three bucks.
Overview
For twenty-three bucks, the Yinyoo CCZ BC04 Pro punches so far above its weight class it's almost unfair. This wired IEM delivers shockingly good sound and a killer microphone for the price of a cheap lunch. The one thing to know? If you're looking for a wired gaming or music headset on a tight budget, this is probably the end of your search.
Performance
What surprised us most was the microphone quality. It's in the 93rd percentile, which is nuts for a $23 IEM. You sound crisp and clear on calls and Discord, and the noise cancellation actually works. The sound profile is bass-forward but controlled, making it great for gaming explosions and electronic music without muddying up vocals.

Value & Pricing
It's an absolute steal. At $23, you're getting sound and mic quality that competes with wired headsets costing three times as much. The value proposition here is off the charts.
Price History
vs Competition
This isn't competing with wireless giants like the Sony WF-1000XM5. Its real rivals are other budget wired IEMs like the KZ ZSN Pro X. The CCZ BC04 Pro trades a bit of build finesse for a significantly better microphone and more effective noise cancellation. If you need a mic for gaming or calls, the CCZ wins. If you're purely a music listener and want a slightly more refined feel, the KZ might be the pick. Compared to something like the Nothing Ear (a), you're giving up wireless convenience for way better sound and mic at a fraction of the price.

Common Questions
Q: Is the noise cancellation good for blocking out background noise?
Yes, surprisingly so. The ANC is in the 82nd percentile, and the in-ear seal combined with the mic's noise cancellation does a solid job of muting keyboard clicks and room ambiance for both you and the listener.
Q: Can I use these with my phone without an amp?
Absolutely. The 16Ω impedance means they get plenty loud straight from a smartphone headphone jack or a USB-C adapter. No extra power needed.
Q: How's the comfort for all-day wear?
Pretty good! The ear hooks and fins keep them secure, and they're lightweight. Some users with smaller ears might find the zinc alloy shells a bit bulky after many hours, but the included tip selection helps.
Who Should Skip This
If you absolutely need wireless freedom, skip this. Go get a CMF Buds Pro 2 instead. Also, if you're a pure audiophile who hates boosted bass and wants a perfectly neutral sound signature, these aren't for you. Look at more balanced IEMs like the Moondrop Chu II.
Verdict
We're giving this a strong recommendation for budget-conscious gamers, streamers, and anyone who needs a great-sounding wired headset with a fantastic mic. The compromises are all in areas you'd expect at this price—mostly build quality and being tethered to your device. For pure performance per dollar, especially for voice communication, it's a champion.
