EarFun EarFun Air Pro 4 Adaptive Hybrid Noise Canceling Review

The EarFun Air Pro 4 delivers 99th percentile sound quality and 98th percentile ANC for just $72. You get Qualcomm Snapdragon Sound with aptX Lossless and LDAC in a comfortable, well-built package. The trade-off is mediocre battery life and an average microphone, but for pure audio performance per dollar, these are hard to beat.

The EarFun Air Pro 4 punches so far above its $72 price tag it's almost comical. We're looking at a feature set that lands in the 98th percentile for ANC and the 99th for sound quality, numbers you'd expect from earbuds costing twice as much. It's built on Qualcomm's Snapdragon Sound platform with aptX Lossless and LDAC support, which is a spec sheet usually reserved for premium models.

But the real story is in the connectivity. Scoring a perfect 100th percentile, these buds have Bluetooth 5.4, multipoint pairing, and even Auracast broadcast audio. You get a full suite of high-end codecs, adaptive ANC that adjusts to your ear shape, and a companion app for EQ tweaking. For under $75, that's a lot of tech to unpack.

Let's talk about where the Air Pro 4 absolutely shines. Its sound quality score sits in the 99th percentile. That's not a fluke. The combination of a Qualcomm QCC3091 chip, support for aptX Lossless and LDAC, and Hi-Res Audio certification means these buds can handle high-bitrate streams without breaking a sweat. The bass is punchy, the mids are clear, and the treble has detail without being harsh. It's a tuned, engaging sound that makes most music genres pop.

The ANC is just as impressive, landing in the 98th percentile with a claimed 50dB of cancellation. The 'adaptive' part means it uses mics to scan your ear canal and adjust the noise canceling profile for a better seal. In practice, it does a stellar job muting constant low-end rumbles like airplane engines or office HVAC. Pair that with a 100th percentile connectivity score thanks to Bluetooth 5.4 and rock-solid multipoint, and you've got a core performance package that rivals earbuds at the $150-$200 mark.

At $72, the Air Pro 4 presents a value proposition that's hard to ignore. You are essentially getting the core audio and ANC performance of earbuds like the Sony WF-1000XM5 or Bose QuietComfort Earbuds for less than half the price. Sure, you sacrifice some polish, app features, and brand cachet, but the fundamental tech—Snapdragon Sound, high-end codecs, adaptive ANC—is all here. When your sound and ANC scores are in the 98th-99th percentile, but your price tag is firmly in the mid-range, that's a winning price-to-performance ratio.

Stacked against direct rivals, the Air Pro 4's data tells a clear story. It demolishes the Anker Soundcore P3i on sound quality and codec support (aptX Lossless vs. basic AAC). It goes toe-to-toe with the Nothing Ear (a) on features but offers more robust ANC. The real comparison is to giants like the Sony WF-1000XM5. The Sony might have slightly more refined ANC and a better app, but it costs over $250. For $72, the EarFun gets you about 90% of the way there on core audio and noise canceling performance. If your budget is tight but you refuse to compromise on sound tech, this is your play.

Skip these if you're a marathon listener who hates charging. With a battery score in the 14th percentile, the 11-hour bud life (52 with case) is solid but not class-leading. Also, if crystal-clear call quality is your top priority, the mic's 43rd percentile ranking means there are better options. And if you just want the cheapest possible buds, look elsewhere—this is a performance pick, not a budget bin special.

If you want flagship-level sound and noise canceling tech without the flagship price, buy the EarFun Air Pro 4. The data doesn't lie: 99th percentile sound and 98th percentile ANC for $72 is a steal. Just go in knowing the battery life isn't class-leading, and the mic is just okay for calls. For music lovers and commuters on a budget, these are arguably the best-value high-performance earbuds on the market right now.
