Score: 87/100
Soundcore P31i
Score: 80/100Rankings

EarFun Air Pro 4 delivers high-resolution audio, strong adaptive ANC, and a long-lasting battery in a budget-friendly package. Its lightweight design, fast charging, and extensive codec support make it a compelling choice, though the build feels plastic and latency may bother serious gamers.

The P31i offers premium-grade adaptive ANC, long battery life and AI translation, positioning it as a strong mid-range contender. Its 11 mm drivers and six-mic system provide solid audio and call quality, though touch controls and lack of spatial audio limit its appeal to audiophiles.

Products in the top-left offer the best value (high score, low price).

Professional reviewers consistently highlight the Air Pro 4's impressive value proposition, noting its strong sound signature, solid ANC for the price point and the inclusion of high-res codecs and Auracast. While the earbuds deliver a feature-rich experience, critics point out that the latency isn't low enough for competitive gaming and the ANC falls short of flagship models on higher frequencies.
Everyday users love the long battery life, punchy bass and reliable ANC for travel, as well as the clear call quality and the novelty of Auracast in public spaces. Common frustrations revolve around the lack of on-ear volume controls, a somewhat finicky companion app, occasional over-sensitive touch inputs, and a case that feels a bit large for pocket storage.

Professional reviewers commend the P31i for delivering premium-grade ANC (-52 dB) and a powerful 11 mm titanium driver package at a competitive price. They highlight the adaptive ANC, extensive six-mic AI call system, and the impressive 50-hour total battery life as major strengths, while noting the absence of spatial audio and high-resolution codecs as drawbacks for audiophiles.
Everyday users rave about the earbuds' price-to-performance ratio, praising the strong ANC, bass response, and the useful AI translation feature. Common complaints focus on overly sensitive touch controls and the need to experiment with ear-tip sizes for a secure fit.
“Battery life is incredible - I only charge the case once a week.”

“The bass is punchy and doesn't muddy the mids - great for hip-hop and rock.”

“ANC blocks out airplane and office noise really well.”
