EarFun Air Pro 4 Review: ANC Earbuds With aptX Lossless for Under $63
Key Features
Active noise cancellation adjusts automatically based on your environment. Cuts out steady background noise like airplane engines and office HVAC pretty effectively.
Supports Qualcomm aptX Lossless codec for CD-quality wireless audio. Also handles LDAC, aptX Adaptive, SBC, and AAC for broad device compatibility.
Custom drivers use a wool-fiber diaphragm that EarFun says delivers warmer mids and tighter bass. In practice, the sound signature leans slightly warm without getting muddy.
Three mics per earbud handle call clarity. Wind noise reduction and AI-based voice isolation make phone calls workable even outdoors.
Earbuds run about 11 hours with ANC off (7.5 with ANC on). The case holds an additional 41 hours. Ten minutes of charging gives roughly two hours of playback.
Connects to two devices simultaneously, so you can switch between your laptop and phone without manual re-pairing.
Our Experience
The EarFun Air Pro 4 punches well above its price bracket. At $63, you are getting features typically found in earbuds that cost two or three times as much — aptX Lossless, adaptive ANC, multipoint connection, and a genuinely long battery life.
Sound quality is where these stand out from most budget competitors. The wool composite drivers produce a tuning that sounds natural and detailed, especially in the midrange. Vocals come through clearly, and bass is present without overwhelming everything else. If you have used earbuds under $80 before and found them muddy or harsh, these are a noticeable step up.
ANC performance is solid for the price. It handles constant low-frequency noise (trains, planes, fans) well. Higher-pitched or sudden sounds still leak through, but that is true of most earbuds outside the $200+ range. Transparency mode works fine for quick conversations without removing the earbuds.
Call quality surprised us. The six-mic setup with AI noise reduction held up in moderate wind and busy coffee shop environments. Callers reported hearing us clearly, which is more than some pricier competitors manage.
Comfort is good for extended wear. The earbuds are lightweight at about 5.4g each, and the included ear tips (six sizes) make it easy to find a secure fit. We wore them for three-hour stretches without fatigue.
The case is compact enough for a jeans pocket and supports wireless charging as well as USB-C. Build quality feels premium relative to the price — no creaky plastic or flimsy hinges.

Frequently Asked Questions
Yes. They connect via Bluetooth and support AAC codec. You will not get aptX Lossless on iOS (that requires an Android device with Qualcomm chip), but audio quality is still very good over AAC.
They carry an IPX5 sweat and splash resistance rating, so they handle gym sessions and light rain. The fit is secure enough for running, though aggressive head movements may loosen them.
Yes. Either earbud works independently in mono mode, which is handy for calls or when you need to keep one ear open.
The six-mic array with AI noise reduction handles work calls well. Background noise from keyboards, fans, and moderate chatter gets filtered out effectively.
