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

Earfun Air Pro 4i are true wireless stereo (TWS) earbuds in white featuring adaptive Active Noise Cancellation (ANC), long battery life, and Bluetooth 5.4 connectivity. The design includes 11 mm titanium-coated composite drivers for enhanced bass and clear highs, a compact charging case with USB‑C and wireless charging support, and on-ear controls for calls and media. The earbuds provide spatial audio options, multipoint device switching and a companion app for EQ and feature customization, making them suitable for everyday listening, remote work and travel.

Advantages

The Earfun Air Pro 4i combine adaptive QuietSmart™ 3.0 ANC of up to 50 dB, LDAC Hi-Res Wireless support and 11 mm drivers to deliver detailed sound with a strong low end and clear mids and highs. Six built-in microphones with AI ENC improve voice clarity during calls. Battery life is substantial both for single-use and with the charging case, and the earbuds support wireless charging and fast USB‑C top-ups. Additional modes such as Theater Mode and Game Mode, plus a companion app for EQ customization, offer flexibility for different listening scenarios.

Suitable for

• Commuting and public transport where noise reduction is required
• Remote work and conference calls needing clear voice transmission
• Listening to music and watching movies with spatial audio or LDAC support
• Light to moderate workouts and outdoor activities (IP55 sweat and water resistance)
• Users who need seamless switching between two devices (multipoint)

When it may not be suitable

These earbuds are optimized for general consumer use rather than professional studio monitoring; audiophiles seeking a perfectly flat reference sound may prefer dedicated studio headphones. In extremely wet conditions or during heavy rain, IP55 protection guards against splashes and sweat but does not make the product fully waterproof.

How to use

Charge the earbuds in the included case using the USB‑C cable or a compatible wireless charger until the LED indicates full charge. Pair the Earfun Air Pro 4i with your device using Bluetooth 5.4 or Google Fast Pair for a one‑touch setup. Use on-ear controls to play/pause media, skip tracks or answer calls; consult the user manual or companion app to customize touch gestures and enable modes such as Game Mode or Theater Mode. For best ANC performance, fit the appropriate ear tips for a secure seal and update firmware through the app when updates are available.

What to consider before purchase

• Intended use: casual listening, calls, commuting, or workouts—these earbuds are not studio reference monitors
• Fit and seal: choose the correct ear tip size from the included set (XS–XL) for optimal sound and ANC performance
• Device compatibility: LDAC and Hi‑Res benefits require a compatible source device and app settings
• Water protection: IP55 resists sweat and light splashes but is not for swimming or heavy immersion

Usage recommendations

For reliable call quality and ANC effectiveness, ensure a snug ear tip fit and enable the appropriate ANC level for your environment. Use Game Mode when low latency is needed and Theater Mode for enhanced spatial sound while watching video. Charge the case periodically to maintain the full advertised battery availability.
