True Wireless Earbuds Earfun Air Pro 4i with Active Noise Cancellation (Black)

Earfun Air Pro 4i in black are true wireless stereo (TWS) earbuds with active noise cancellation (ANC) designed for everyday listening, commuting, remote work and hands-free calls. The earbuds combine 11 mm titanium-coated composite drivers, LDAC support and 3D surround audio to deliver detailed sound with pronounced bass and clear highs. Adaptive QuietSmart™ 3.0 ANC reduces ambient noise by up to 50 dB. Built-in microphones with AI ENC improve voice clarity during calls. A compact charging case provides extended battery life and supports USB-C and wireless charging for convenient on-the-go use.

Advantages

The Earfun Air Pro 4i offer adaptive noise cancellation that adjusts to surroundings, improving focus in noisy environments. Large 11 mm drivers with titanium coating and LDAC support enable higher-fidelity wireless audio and enhanced spatial impression. Multipoint connectivity, Google Fast Pair and Bluetooth 5.4 provide stable, low-latency connections and simple pairing across devices. The earbuds combine long battery life with fast charging options and an IP55 sweat and moisture protection rating suitable for active use.

Suitable for

• Commuting and travel where noise cancellation improves comfort
• Remote work and online meetings requiring clear voice transmission
• Listening to music and watching movies with spatial audio and LDAC support
• Exercise and outdoor activities where sweat protection is needed

When it may not be suitable

These earbuds may not be the best choice for users who need full water immersion protection, as the IP55 rating protects against sweat and splashes but is not rated for swimming. They may also be unnecessary for users who do not require ANC or high-resolution wireless audio and prefer simpler, lower-cost models.

How to use

Place the earbuds in the charging case to charge, and use the included USB-C cable or a compatible wireless charger for the case. Remove the earbuds from the case to power them on and enter pairing mode; they support Google Fast Pair for quick setup with compatible devices.

During calls, the built-in microphones with AI ENC will reduce background noise automatically; adjust ANC levels as needed to balance awareness and isolation.

What to consider before purchase

• IP55 rating — suitable for sweat and light splashes but not for swimming or heavy water exposure
• ANC performance — adaptive ANC reduces noise up to 50 dB but effectiveness depends on environment and fit
• Device compatibility — LDAC and some features require a compatible source device and the companion app for full customization
• Fit and ear tip sizes — multiple ear tip sizes are included; proper fit affects sound quality and noise cancellation

Usage recommendations

For best ANC performance and sound quality, select the ear tip that provides a secure seal and enable QuietSmart™ 3.0 in noisy environments. Use Game Mode to reduce latency when playing games and Theater Mode for improved spatial audio during video playback. Charge the case via USB-C or a wireless charger before travel, and enable multipoint when you need to switch seamlessly between two devices.
