EarFun Air Pro 4+ Adaptive Noise Cancelling Earbuds - Hi-Res Sound

In this review the EarFun Air Pro 4+ stand out as a strong choice for listeners who want detailed, room-filling sound plus serious noise suppression without a heavy price premium. The single biggest reason to buy is the combination of a hybrid dual-driver system and extensive codec support, which together deliver noticeably better clarity, bass weight and treble extension than most rivals in the same category. For commuters, remote workers and mobile audiophiles who value call clarity and long battery life, these earbuds offer a compelling balance of features and real-world performance.

Key Features

• Dual-Driver Synergy: The hybrid 10mm dynamic driver paired with a FeatherBA balanced armature produces a clear soundstage with robust bass, articulate mids and crisp highs.
• Hi-Res Audio and aptX Lossless: Qualcomm QCC3091 with Snapdragon Sound and aptX Lossless support lets high-resolution tracks resolve finer detail compared with basic SBC playback.
• Adaptive Hybrid ANC: EarFun QuietSmart 3.0 adjusts noise cancellation in real time and can reduce ambient noise up to around 50dB for focused listening in loud environments.
• 6-Mic AI Calls: A six-microphone array with AI beamforming and Qualcomm cVc 8.0 improves voice pickup and reduces background noise on calls.
• Long Battery Life: Up to 12 hours per charge and around 54 hours with the charging case, plus a 10-minute quick charge that provides about 3 hours of playback.
• Bluetooth 6.0 with Multipoint: Stable low-energy connections to two devices at once and Auracast support for public audio broadcasts and sharing.

Who It's For

The EarFun Air Pro 4+ are ideal for people who prioritize sound quality and noise cancellation in everyday use: commuters, frequent travelers, and anyone who listens to a mix of music and spoken-word content and wants better fidelity than typical single-driver earbuds. The advanced codec support will particularly benefit listeners with high-resolution music sources or phones that support LDAC, aptX Lossless or LC3.

Those who should look elsewhere include strict audiophiles seeking fully balanced planar drivers or modular ear tips for the ultimate fit, and users who require fully transparent, studiograde monitoring rather than consumer tuned sound. Also, people without devices that support advanced codecs will still get very good sound, but will not experience the full hi-res benefit.

Pros & Cons

Pros

• Excellent tonal balance and stereo imaging from the hybrid dual-driver design.
• Very effective adaptive ANC that makes noisy commutes and cafes much more manageable.
• Clear, professional-sounding calls thanks to the 6-mic AI beamforming and cVc processing.
• Long combined battery life and useful fast-charge capability for on-the-go use.

Cons

• Advanced codec benefits require compatible source devices, so some users may not hear the full hi-res advantage.
• Fit and seal will vary by ear shape, and those needing a custom fit may want alternatives with more tip options.
