Earfun Earbuds EarFun Air Pro 4+ ANC True Wireless Earbuds Blue, model TW700E

The EarFun Air Pro 4+ ANC True Wireless Earbuds (Blue) are compact in-ear headphones designed for daily listening, calls and commuting. Featuring a dual-driver design (balanced armature + 10 mm dynamic driver), support for high-resolution codecs and Qualcomm Snapdragon Sound, these TWS earbuds aim to deliver detailed audio, effective noise cancellation and long battery life. The package includes a charging case with wireless and USB‑C charging, multiple ear tip sizes and access to the EarFun app for sound and control customization.

Advantages

The combination of an ultra-light balanced armature driver and a 10 mm dynamic driver provides extended frequency detail with controlled bass, clear midrange and crisp highs. Support for Snapdragon Sound, aptX Lossless and LDAC enables higher-bandwidth Bluetooth audio for better fidelity when paired with compatible devices. Adaptive Hybrid ANC with QuietSmart 3.0 reduces ambient noise, while six microphones with AI processing and Qualcomm cVc 8.0 improve call clarity. Long battery life, fast charging and Bluetooth 6.0 with multipoint and Auracast increase practical usability for commuting, work and leisure.

Suitable for

• Listening to music with emphasis on clarity and wide frequency response
• Phone calls and remote work where clear voice transmission is needed
• Commuting, travel and public transport where ANC reduces background noise
• Mobile gaming or video watching requiring low-latency audio
• Active use in light exercise or outdoor conditions thanks to IP55 rating

When it may not be suitable

If you require fully passive sound isolation for very loud environments, in-ear ANC combined with the given fit may not fully eliminate all external noise in extreme situations. Also, to take full advantage of aptX Lossless or LDAC high-resolution streaming you need a source device that supports those codecs; otherwise you will receive standard Bluetooth audio quality.

Toggle ANC modes and low-latency mode from the app or via touch controls on the earbuds. Charge the case using the included USB‑C cable or on a compatible wireless charger; a short 10‑minute charge delivers several hours of playback for quick reuse.

What to consider before purchase

• To benefit from aptX Lossless or LDAC you need a source device that supports those codecs.
• Fit and seal affect both sound quality and ANC performance; try different ear tip sizes for the best result.
• Battery life varies with volume level, ANC usage and codec selection.

Usage recommendations

For best audio quality, enable Snapdragon Sound or aptX Lossless / LDAC on a compatible source device and use the EarFun app to fine-tune the EQ. Use the ear tips that give a tight seal for improved bass response and ANC performance. When making calls in noisy environments, enable the voice-enhancing call mode if available in the app to maximize clarity.
