How We Tested ANC Earbuds
Active noise cancellation performance varies dramatically between earbuds, and spec sheets rarely tell the full story. We tested 12 pairs of ANC earbuds in three real-world environments: airplane cabins (constant low-frequency drone), subway trains (variable rumble and announcements), and open-plan offices (keyboard clicks, conversations, HVAC noise). We also measured ANC depth in decibels using calibrated equipment at multiple frequencies.
Best Overall: Sony WF-1000XM6
Sony's sixth-generation flagship delivers the best ANC we have measured in an earbud — 38dB of noise reduction at 200Hz, which translates to making airplane engines sound like a gentle hum. The new integrated processor V3 handles adaptive ANC adjustments in real-time, and the LDAC codec support delivers near-lossless audio quality. Battery life reaches 8 hours with ANC on (12 hours in the case), and the IPX4 rating handles sweat and rain.
Best for iPhone: AirPods Pro 3
Apple's latest AirPods Pro deliver exceptional ANC that rivals Sony, with the added advantage of seamless ecosystem integration. Adaptive Audio automatically adjusts transparency and noise cancellation based on your environment. The new hearing health features — including real-time hearing protection in loud environments and clinical-grade hearing tests — make these more than just earbuds.
Best Budget: EarFun Air Pro 4
At $69, the EarFun Air Pro 4 delivers ANC performance that approaches much more expensive options. The aptX Adaptive codec provides good audio quality, and the 10-hour battery life with ANC on outperforms many premium competitors. The main trade-off is build quality — the case feels plasticky — but the audio and ANC performance is remarkable at this price.
Best for Android: Samsung Galaxy Buds 4 Pro
Samsung's latest earbuds offer the best Android integration, with seamless device switching across Samsung phones, tablets, and watches. The ANC is strong (35dB at 200Hz), the 24-bit audio codec delivers excellent sound quality, and the new AI-powered voice detection automatically pauses music when you start speaking.
