EarFun has introduced the Air Pro 4+, a true wireless stereo (TWS) earbud set that redefines affordable premium audio. Priced just under $100, these earbuds bring advanced audio technologies typically found in more expensive devices. This offers budget-conscious consumers a compelling blend of quality and innovation.
The Air Pro 4+ features a hybrid dual-driver system combining a 10mm dynamic driver with a balanced armature unit. This configuration delivers detailed, powerful sound with a well-balanced tonal response. According to EarFun, the tuning aligns with the Harman target curve, producing solid bass without overpowering mids or highs.
Innovative Design and Durability
The earbuds retain the glossy dual-tone finish typical of the brand but introduce a surprisingly practical form factor. Although the stem is somewhat large, it provides ease of handling and a secure fit for extended wear. The charging case features a novel vertical opening mechanism, reminiscent of mid-engine sports cars, exposing much of the interior when opened. This gives the case a visually striking and functional design.
Furthermore, the Air Pro 4+ carries an IP55 rating, ensuring resistance to dust and water splashes. This level of protection enhances durability for everyday use, particularly during workouts or outdoor activities where exposure to sweat or rain is common.
Advanced Audio Codecs and Connectivity
One key advantage of the Air Pro 4+ is its exceptional codec support. Besides baseline standards SBC and AAC, the earbuds support high-resolution standards including LDAC, aptX Adaptive, and notably aptX Lossless. Having aptX Lossless at this price range is currently rare, enabling users to experience audio with minimal compression artifacts, assuming compatible source devices.
In addition, the earbuds utilize Bluetooth Low Energy with LC3 and Auracast technologies for improved connectivity and broadcast capabilities. The latency is impressively low at 50 milliseconds, reducing audio lag during gaming or video playback.
Software and AI Features
The EarFun Audio app, available for both Android and iOS, controls various settings and customization options. It provides a straightforward interface, making adjustments seamless for users. Among the newer features is an AI Translation tool designed to transcribe and translate foreign language speech in real time, similar in concept to AirPods Pro 3’s translation capability.
However, this AI feature is still in a developmental phase. Users reported slow translation speeds and occasional inaccuracies, limiting its practical use for real-time conversations. Still, the potential remains promising, and software updates could enhance this function over time.
Why EarFun Air Pro 4+ Stands Out
- Hybrid dual-driver setup (dynamic + balanced armature) for premium sound quality.
- Extensive codec support: LDAC, aptX Adaptive, aptX Lossless, SBC, AAC.
- Active Noise Cancellation (ANC) and six built-in microphones for clear voice calls and noise reduction.
- IP55-rated case and earbuds provide robust protection against dust and water.
- Unique vertical-opening case design enhancing aesthetics and usability.
- Low 50ms latency supports lag-free multimedia experiences.
EarFun Air Pro 4+ effectively capitalizes on familiar flagship features typically priced well above $100. Its sound quality approaches audiophile standards, making it a valuable option for enthusiasts and everyday users alike.
While the AI translation feature needs refinement, it does not detract from the device’s core strengths. Instead, it reflects EarFun’s commitment to innovation beyond sound performance.
With this model, EarFun pushes the boundaries of what can be offered in a mid-range TWS device. It challenges competitors by marrying sophisticated hardware with an affordable price point. Buyers seeking a premium sound experience without overspending should consider the Air Pro 4+ as a top contender in 2026’s TWS market.
