There’s a universal quest we all embark on: the search for a personal bubble. For me, that bubble is built with sound. It’s the driving beat of a synthwave track that powers my workout, the nuanced dialogue of a podcast on a crowded train, or the immersive score of a film that transforms my living room into a cinema. For years, achieving this level of audio immersion meant one of two things: bulky, expensive over-ear headphones, or premium earbuds with a price tag that made my wallet weep. The challenge has always been to find that perfect intersection of high-fidelity audio, potent noise cancellation, and a price that doesn’t feel like a compromise. It’s a frustrating search, often leading to earbuds that excel in one area but fail spectacularly in another, leaving you with muddy bass, weak ANC, or a battery that dies mid-commute. This is the precise problem the EarFun Air Pro 4 aptX Lossless ANC Wireless Earbuds aim to solve, promising a suite of flagship-level features that seem almost too good to be true for their price point.

What to Consider Before Buying Wireless Earbuds
A set of wireless earbuds is more than just an accessory; it’s a key solution for reclaiming your audio space in an increasingly loud world. They offer freedom from tangled wires, portability for an on-the-go lifestyle, and advanced technology to filter out distractions, allowing you to focus, relax, or simply enjoy your media with unparalleled clarity. The main benefits are clear: convenience, immersion, and the ability to seamlessly integrate high-quality sound into every facet of your day, from business calls to gym sessions.
The ideal customer for a product like this is someone who values audio quality and versatility but is also budget-conscious. This includes students, daily commuters, fitness enthusiasts, and remote workers who need reliable call quality and noise cancellation without investing in top-tier brands that can cost two or three times as much. Conversely, these might not be the best fit for pure audiophiles who prefer the uncompressed, raw performance of wired in-ear monitors and are willing to sacrifice convenience for absolute sonic purity. For those individuals, a wired set might be a better alternative. For others deeply embedded in a specific tech ecosystem (like Apple), the seamless integration of first-party buds might outweigh the cost savings.
Before investing, consider these crucial points in detail:
- Fit & Comfort: Earbuds live in your ears, sometimes for hours at a time. A secure, comfortable fit is non-negotiable. Look for models that include multiple sizes of silicone or foam eartips to ensure a proper seal. A good seal not only enhances comfort but is also critical for passive noise isolation and optimal bass response.
- Audio Performance & Codecs: The heart of any earbud is its sound quality. Key performance indicators include driver size and type, but the audio codecs they support are paramount. Standard codecs like SBC are universal but offer lower fidelity. For higher quality, look for AAC (great for Apple devices), and for Android users, aptX variants (like aptX Lossless) and LDAC are the gold standard for near-CD quality wireless audio.
- Noise Cancellation & Transparency: Active Noise Cancellation (ANC) uses microphones to detect and cancel out ambient sounds. The effectiveness is often measured in decibels (dB) of reduction. A good pair of earbuds should significantly reduce low-frequency rumbles like engine noise. Equally important is a good transparency or ambient mode, which lets you hear your surroundings without removing the buds—a crucial safety feature for runners and commuters.
- Battery Life & Charging: Check the battery life for both the earbuds on a single charge and the total playtime with the charging case. Look for a minimum of 5-6 hours on the earbuds with ANC on. Features like quick charging (e.g., 10 minutes for 2 hours of playback) and wireless charging add significant convenience to your daily routine.
We’ve put dozens of earbuds through their paces, and while the EarFun Air Pro 4 aptX Lossless ANC Wireless Earbuds present a compelling package, understanding the broader market is key to making the right choice for your needs.
While the EarFun Air Pro 4 aptX Lossless ANC Wireless Earbuds is an excellent choice, it’s always wise to see how it stacks up against the competition. For a broader look at all the top models, we highly recommend checking out our complete, in-depth guide:

First Impressions: Premium Experience Without the Premium Price Tag
Unboxing the EarFun Air Pro 4 aptX Lossless ANC Wireless Earbuds immediately sets a positive tone. The packaging is clean and professional, but the real surprise comes when you open the charging case. It’s a smooth, matte black composite case with a satisfying magnetic snap. It feels sturdy without being overly heavy, though some users have noted it’s a bit larger than some competitors. Inside, the earbuds themselves are nestled securely. They have a familiar stemmed design that we found helps with microphone placement and makes them easy to handle.
What truly impressed us, and a point echoed by many users, was the generous inclusion of five total pairs of eartips. This is a small detail that makes a huge difference. As one user replacing their old Pixel Buds noted, “I was immediately impressed with the 4 extra sizes of rubber tips… Experimenting with them, I got a good fit for each ear and man these things are comfortable.” We spent a few minutes finding the perfect size, and the resulting seal was snug and secure, passing the “head shake” test with ease. Pairing with our Android phone was instantaneous thanks to Google Fast Pair—a pop-up appeared on screen the moment we opened the case. This seamless setup experience makes you feel like you’re using a product that costs far more, a theme that would continue throughout our testing. You can see its full feature set and learn more about its compatibility online.

Deep Dive: A Feature-Packed Performance That Defies Its Price
After spending several weeks integrating the EarFun Air Pro 4 aptX Lossless ANC Wireless Earbuds into every part of our daily routine—from morning commutes and focused work sessions to intense workouts and late-night calls—we can confidently say they punch far, far above their weight class. This isn’t just about a long list of specs on a box; it’s about how those features translate into a cohesive and genuinely premium user experience.
The Sonic Landscape: A Playground for Your Ears
The headline feature here is the staggering array of high-fidelity audio codecs, a collection typically reserved for earbuds commanding double the price. With support for Qualcomm’s Snapdragon Sound and aptX Lossless, Sony’s LDAC, and the future-proofed LE Audio with LC3, these earbuds are equipped to handle virtually any high-resolution audio stream you throw at them. We tested this with a Snapdragon-powered Android phone, streaming lossless tracks from a compatible service. The difference was immediately audible. On tracks like Daft Punk’s “Giorgio by Moroder,” the separation between the crisp hi-hats, the warm synth bass, and the intricate layers of the monologue was exceptional. The 10mm hybrid drivers deliver a sound that is, out of the box, surprisingly balanced and dynamic. As one user put it, “El sonido es balanceado y los medios son buenisimos… no tiene bajos feos ni sucios y los agudos no son chirriantes y dolorosos.” (The sound is balanced and the mids are very good… it doesn’t have ugly or dirty bass and the highs are not shrill or painful.)
While the default tuning is excellent, the EarFun Audio App is where you can truly tailor the sound to your preference. The 10-band equalizer is robust, allowing for precise adjustments. We found a popular community EQ setting online that added a touch more sub-bass and sparkle to the treble, and the earbuds responded beautifully. This level of customization is a game-changer. Whether you’re a bass-head or prefer a flat, analytical profile, you can achieve it here. This audio prowess is a feature that really sets it apart in the crowded mid-range market.
Building a Wall of Silence: QuietSmart 3.0 ANC in Action
Active Noise Cancellation is often where budget-friendly earbuds stumble, but the EarFun Air Pro 4 aptX Lossless ANC Wireless Earbuds stand their ground impressively. The QuietSmart 3.0 adaptive hybrid ANC, rated up to 50dB, is shockingly effective. We took them onto a noisy subway car, and with ANC enabled, the low-frequency rumble of the train was reduced to a faint hum, allowing us to listen to a podcast at just 40% volume. In a bustling coffee shop, the chatter of patrons and the clatter of dishes faded into the background, creating a serene bubble of focus.
Perhaps the most vivid testament to its power came from a user who shared their experience while mowing their lawn. “I got on my mower all excited and the sound was weak… Then I turned on the noise canceling. Holy crap! I thought my mower had died.” This is exactly what we experienced; the ANC is particularly adept at eliminating constant, droning noises. The app offers several modes, including an “AI environment noise canceling” setting that we found worked brilliantly as a set-it-and-forget-it option. The ambient sound mode is equally well-implemented, piping in external audio clearly and naturally, making it easy to have a quick conversation or listen for traffic announcements without ever pausing the music.
All-Day Endurance and Real-World Connectivity
Battery life is an absolute monster on these earbuds. EarFun claims up to 11 hours on a single charge (with ANC off) and a colossal 52 hours total with the case. In our real-world testing with ANC on and volume at 60%, we consistently got between 7 and 8 hours of continuous playback, which is more than enough to power through a full workday. The case easily provided four additional full charges, meaning we only had to plug it in about once a week with moderate daily use. The quick-charge feature is a lifesaver, delivering 2 hours of juice from just a 10-minute charge.
Connectivity, powered by Bluetooth 5.4, was mostly stable and reliable. The Multipoint connection feature is a highlight, allowing us to be paired to both our laptop and phone simultaneously. We could listen to music from our computer and seamlessly switch to an incoming call on our phone without touching any settings. However, this is where we encountered some of the issues mentioned in more critical user reviews. One user reported that enabling “advanced” features could “destabilize these buds usefulness,” leading to intermittent pauses or connection drops. We did experience a single instance where the right earbud disconnected, requiring us to place both buds back in the case to reset. A quick firmware update via the app seemed to improve stability, suggesting these are software quirks that EarFun is actively addressing. Similarly, the touch controls, while responsive, can be a bit sensitive, occasionally registering an accidental touch when adjusting the fit. Thankfully, these can be fully customized or even disabled in the app.
What Other Users Are Saying
The consensus around the EarFun Air Pro 4 aptX Lossless ANC Wireless Earbuds is overwhelmingly positive, with most users marveling at the value proposition. One happy customer, a longtime EarFun fan, summarized it perfectly: “What keeps me coming back to EarFun is the unbeatable combination of excellent sound quality, advanced features, and fair pricing… you get premium features without the premium cost.” Many, like the user who switched from AirPods and Bose, were simply “wow’d” by the easy setup, comfortable fit, and excellent out-of-the-box sound.
However, the feedback isn’t universally perfect. The most common critique revolves around software stability and quality control. One user had to return their first pair, noting the sound quality was “significantly worse” than a previous model, but was completely satisfied with the replacement, highlighting the excellent customer service. Another user on their 30th day of ownership was “at 51% keep,” frustrated by intermittent connection drops and overly sensitive touch controls that destabilized the experience. These reports suggest that while the hardware is incredibly capable, the software experience can sometimes require a bit of patience, a firmware update, or a quick reset to work out the kinks.
How Does the EarFun Air Pro 4 Compare to the Alternatives?
While the EarFun Air Pro 4 aptX Lossless ANC Wireless Earbuds carves out a powerful niche, it exists in a competitive landscape. Here’s how it stacks up against some notable alternatives.
1. Linsoul KZ ZS10 Pro 5 Driver Wired Earbuds

- 【PCB Dividing Board】The PCB board is added to give full play to all the drivers, displaying a smooth, sensible, detailed music experience. The ZS10 Pro overall has dynamic lows and bright...
The Linsoul KZ ZS10 Pro is a completely different beast, aimed squarely at the budget audiophile who prioritizes raw sound fidelity above all else. As a wired in-ear monitor (IEM), it completely sidesteps issues of Bluetooth codecs, battery life, and connectivity. Its five-driver hybrid setup (one dynamic, four balanced armature) delivers a level of detail and clarity, especially in the mids and highs, that wireless audio in this price range simply cannot match. However, you sacrifice every modern convenience: there are no wires, no ANC, no built-in mic (on this version), and no app. This is the choice for critical listening at a desk, not for a workout or a noisy commute.
2. Apple AirPods Pro 2 Active Noise Cancellation Earbuds
- PIONEERING HEARING — AirPods Pro 2 unlock the world’s first all-in-one hearing health experience: a scientifically validated Hearing Test,* clinical-grade and active Hearing Protection.*

The Apple AirPods Pro 2 represent the premium, ecosystem-driven alternative. If you are an iPhone, Mac, and iPad user, the seamless H2 chip integration, automatic device switching, and Personalized Spatial Audio are features the EarFun cannot replicate. Apple’s ANC and Transparency Mode are widely considered the best in the business, offering a slightly more effective and natural-sounding experience. However, this performance comes at a significantly higher price, often more than double that of the EarFun. For Android users, the AirPods Pro 2 lose much of their “magic,” making the EarFun Air Pro 4 aptX Lossless ANC Wireless Earbuds a far more logical and feature-rich choice.
3. Beats Solo Buds Wireless Earbuds
- Up to 18 hours of battery life. Fast Fuel, a 5-minute charge, gives up to 1 hour of playback. POWER ADAPTER AND USB-C CHARGING CABLE SOLD SEPARATELY.
- Custom acoustic architecture for big Beats sound with full range and clarity.
- The smallest case we’ve ever made, making these powerful earbuds the perfect on-the-go companion.
The Beats Solo Buds target a different user entirely. They focus on a compact design, a very long 18-hour single-charge battery life, and the signature bass-heavy sound profile Beats is known for. While they offer both Apple and Android compatibility, they make a major compromise by completely omitting Active Noise Cancellation and a charging case (the included pod is for carrying only). This makes them a poor choice for anyone looking to block out ambient noise for commuting or focus. They are better suited for users who prioritize extreme battery life and a powerful bass response for workouts in a controlled environment, and who don’t need ANC.
Our Final Verdict: Is It Worth It?
After extensive testing, we can say with confidence that the EarFun Air Pro 4 aptX Lossless ANC Wireless Earbuds are not just worth it; they are a new benchmark for what is possible in the sub-$100 wireless earbud category. They deliver a suite of features—aptX Lossless, LDAC, powerful adaptive ANC, and massive battery life—that were, until now, the exclusive domain of premium products costing two or three times as much. The sound quality is excellent and highly customizable, the noise cancellation is genuinely effective, and the comfort is superb for long listening sessions.
While not without minor flaws, such as occasional software quirks and sensitive touch controls, these issues are largely addressable through the companion app and firmware updates. For the vast majority of users, these are negligible trade-offs for the immense value on offer. If you are an Android user looking for the highest possible audio fidelity without breaking the bank, or anyone seeking flagship features on a mid-range budget, your search should end here. The EarFun Air Pro 4 is a triumph of engineering and value that is incredibly easy to recommend. To experience this exceptional combination of features and affordability for yourself, you can check the latest price and availability right now.
