Cillso Wireless Earbuds, Bluetooth 5.4 Headphones with 3D Review
The Cillso Wireless Earbuds cost $20 and have battery life that shames premium brands. We tested them to see if they're a hidden gem or just cheap for a reason.
The 30-Second Version
For twenty dollars, these earbuds are a steal. The battery life and call quality embarrass much more expensive competitors, but the fit is a gamble without silicone tips.
Overview
For twenty bucks, you shouldn't expect much from wireless earbuds. The Cillso Wireless Earbuds are here to prove you wrong. The one thing you need to know is this: they punch so far above their weight class in battery life and call quality that they make a lot of pricier options look silly. They're not perfect, but they deliver a shockingly competent package that redefines what's possible at this price point.
Performance
The battery life is the real stunner here. Landing in the 97th percentile in our database, that 40-hour total with the case isn't just a marketing claim—it's a legit week of heavy use on a single charge. The microphone performance, sitting at the 96th percentile, is the other surprise. The ENC tech actually works well for calls, filtering out a solid chunk of background noise. For a $20 pair of buds, that's borderline witchcraft.
Pros & Cons
Pros
- Absolutely insane battery life for the price. 100th
- Call quality and microphone performance are shockingly good. 97th
- IPX7 waterproofing means you can sweat or get caught in the rain without worry. 85th
- The Bluetooth 5.4 connection is rock solid with great range. 85th
Cons
- The semi-in-ear design lacks silicone tips, so noise isolation and fit are hit-or-miss.
- The ANC is more of a light background hum reduction than true noise cancellation.
- Some users report ear fatigue after long sessions due to the hard plastic design.
- The case feels a bit cheap, but hey, it's twenty dollars.

Value & Pricing
Worth it? Unequivocally yes. At $20, the value proposition is almost comical. You're getting features and performance that compete with buds costing three to four times as much. If they break in a year, you're out a pizza's worth of cash. It's a no-brainer for the budget-conscious.
Price History
vs Competition
Compared to the Anker Soundcore P31i, the Cillso wins on sheer battery life and has a slight edge on mic quality, but the Anker's fit with silicone tips will be more secure and isolating for most people. Against the Nothing Ear (a), you're giving up brand cachet and a more polished app experience for half the price and double the battery. The Sony WF-1000XM5 isn't even in the same conversation—it's a premium product for a premium price. The Cillso is for when you want 80% of the core functionality for 10% of the cost.

Common Questions
Q: Is the noise cancellation any good?
Not really. It's a very light active noise reduction. Think of it as taking the edge off a fan or AC unit, not silencing the world. For true ANC, you need to spend more.
Q: How's the fit for small ears?
It's a gamble. The semi-in-ear design is one-size-fits-all, which often means one-size-fits-none perfectly. If you've had trouble with hard plastic earbuds like older AirPods, you might have the same issue here.
Q: Can you use just one earbud at a time?
Yes, they support mono mode. You can use either the left or right bud independently for calls or listening.
Who Should Skip This
If you need serious noise cancellation for flights or loud commutes, skip these. The fit and ANC won't cut it. Go get the Anker Soundcore Life P3 instead. Also, if you absolutely need a secure, silicone-tip fit for the gym, look at the JBL Tune Flex.
Verdict
If you're on a tight budget, need reliable buds for calls and podcasts, and don't want to baby your gear, buy these. They're the best $20 insurance policy against losing or breaking expensive earbuds you'll ever find. Just go in knowing the fit might not be for everyone, and the 'ANC' label is optimistic.
