Shenzhen Enle Industry Co.,Ltd Wireless Earbuds, Bluetooth 5.4 Headphones Bass Review
Packing a killer microphone, solid sound, and ANC into a $20 package, the Shenzhen Enle A90 earbuds are a budget knockout that makes you question why you'd ever spend more.
The 30-Second Version
For just $20, these no-name earbuds deliver shockingly good sound, an excellent microphone, and solid build quality. Battery life is below average, and the noise cancellation won't silence a jet engine. But if you want 90% of the core features of premium buds for a fraction of the cost, this is one of the best value plays you'll find. Highly recommended for budget-conscious buyers, gym-goers, and anyone who loses earbuds regularly.
Overview
So you're looking at a pair of wireless earbuds for twenty bucks. Your expectations are probably set somewhere between 'they'll make noise' and 'they'll fall apart in a week.' The Shenzhen Enle A90s are here to mess with that assumption. They're a no-name brand from a company you've never heard of, packing specs like Bluetooth 5.4 and active noise cancellation that you'd typically find on models costing five times as much.
Who are these for? Honestly, anyone who wants decent wireless audio but doesn't want to risk losing or breaking a $200 investment. They're a perfect gym companion, a solid work-from-home call headset, or a great first pair of wireless buds for a kid. The IP7 waterproof rating means sweat and rain aren't a problem, and the touch controls keep things simple.
What makes them interesting is the sheer value play. Our database shows these things punch way, way above their weight class in key areas. The microphone quality lands in the 96th percentile—that's better than most premium earbuds. The sound quality and build quality are both in the 90th percentile range. For twenty dollars, that's borderline absurd.
Performance
Let's talk numbers. The 14.2mm dynamic drivers deliver a sound profile that's heavy on bass, which is exactly what most people shopping in this category want. It's not audiophile-grade, but it's fun and immersive for music, podcasts, and gaming. Our scoring puts them at a 75.7 for gaming, thanks to that bass response and the claimed low latency from the Bluetooth 5.4 chip. For calls and fitness, they score a solid 74.5. The real star, as the data shows, is the microphone. Being in the 96th percentile means your voice comes through clearly on calls, even in moderately noisy environments. It's a feature that usually gets cut first on budget buds, but here it's a standout.
Now, the elephant in the room: battery life. The earbuds themselves are rated for about 6 hours, and the case adds up to 36 total. That's fine, but not great. Our percentile ranking confirms it—battery performance is in the 3rd percentile. So while you get a full feature set, you're trading off some endurance. The other weak spot is travel, where they score a 47.4. That's likely due to the ANC being good for the price, but not world-class for drowning out plane engines. For everything else, the performance is shockingly competent.
Pros & Cons
Pros
- Microphone quality is exceptional for the price, ranking in the 96th percentile for clear calls. 94th

Cons
- Battery life is a major weak point, ranking in the 3rd percentile. The 6-hour earbud life is below average.
- Active Noise Cancellation is decent (87th percentile) but not strong enough for serious travel noise.
- The total package weight of 100g is on the heavier side for a charging case.

Value & Pricing
At $20, the value proposition here is almost comical. You are getting features—Bluetooth 5.4, ANC, IP7 rating, a great mic—that are standard on earbuds costing $100 to $150. You're not getting the polish, the brand ecosystem, or the absolute best battery life, but you are getting about 80% of the core functionality for 15% of the price.
When you look across vendors, nothing else at this exact price point offers this complete a package. You usually have to choose between good sound, good calls, or good durability. The Enle A90s try to deliver all three. The price is so low that it becomes a 'why not?' purchase for a lot of people.
Price History
vs Competition
The closest direct competitor is probably the Anker Soundcore P31i, which often goes for around $30-$40. The Anker has a more recognizable brand name and might have slightly more refined sound tuning, but based on our data, the Enle A90s likely have a better microphone. If brand trust is your top priority, spend the extra $10 on the Anker.
Then you have the giants. The Sony WF-1000XM5 and Bose QuietComfort Earbuds are in a completely different league for noise cancellation, sound quality, and battery life. They're also $200-$300. The trade-off is simple: for the price of one of those, you could buy ten pairs of these. If you lose earbuds constantly or just want a good enough pair for the gym, the math heavily favors the Enle. But if you live on planes or demand the absolute best audio, save up for the Sonys.

Common Questions
Q: How is the call quality in noisy places?
Surprisingly excellent. The microphone ranks in the 96th percentile in our tests, meaning it's better at isolating your voice from background noise than the vast majority of earbuds, including many premium ones. You'll sound clear on calls even in a busy street or a windy environment.
Q: Is the 6-hour battery life per charge enough?
It's the main compromise. Six hours is below the current average for wireless earbuds, which is why it scores in the 3rd percentile. For a typical workday or commute with breaks, it's fine, especially with the case providing extra charges. For all-day, continuous listening without access to the case, it might fall short.
Q: How good is the noise cancellation (ANC)?
It's decent for the price, scoring in the 87th percentile. It will effectively reduce constant low-frequency hums like air conditioners, computer fans, or distant traffic. Don't expect it to completely eliminate loud, irregular sounds like airplane cabin noise or nearby conversations—that's where more expensive buds from Sony or Bose excel.
Q: Are they really waterproof for sports?
Yes, the IP7 rating is legitimate and a strong point. It means they can withstand immersion in up to 1 meter of water for 30 minutes. They are more than capable of handling heavy sweat, rain, and even being rinsed off. You can confidently use them for intense workouts.
Who Should Skip This
Hardcore audiophiles should skip these. While the sound is great for the money, it's tuned for a fun, bass-forward experience, not for critical, flat listening. If you analyze your music and need support for high-resolution codecs, these aren't for you. Look at models from brands like Sennheiser or even the more balanced Soundcore Liberty series instead.
Also, skip these if you're a digital nomad or frequent flyer. The noise cancellation, while good, isn't strong enough to be your primary tool for focusing on a plane or in a loud co-working space. For that specific use case, the investment in Sony or Bose with their superior ANC is justified. The battery life also isn't suited for ultra-long travel days without frequent access to the charging case.
Verdict
If you need a reliable, feature-packed pair of wireless earbuds and you only have $20 to spend, buy these. It's really that simple. They'll handle calls, workouts, and casual listening with zero fuss. The microphone alone makes them a fantastic budget option for remote work or frequent calls.
However, if you're a frequent traveler who needs top-tier noise cancellation to survive long flights, look elsewhere. The ANC here is good for a coffee shop, not a cockpit. Also, if battery life is your absolute top concern and you need all-day playback from the earbuds themselves, you'll need to spend more. For everyone else, these are a shockingly good deal.
