EarFun Air Pro 4

Who doesn't know this: You want to try out the very latest audio standards like lossless Hi-Res streaming, Auracast, and massive noise cancelling, but you strictly refuse to pay over 200 euros for it. The EarFun Air Pro 4, released in late summer 2024, solves this everyday problem. Even in spring 2026, they are considered the undisputed "spec monster" in the budget segment within the tech community, outclassing many expensive flagships on the spec sheet.

Classification and target audience check

These in-ears are clearly aimed at the "tech optimizer" (our persona Markus) and smart savers. If you count every euro but still demand maximum tech features for your Android smartphone, you’ve come to the right place. They are the direct, slightly more feature-rich competitors to the popular models from Soundcore or Nothing.

Design and feel

Upon unpacking the frustration-free packaging, it’s positively noticeable: The nose test passes, there’s no biting chemical smell, which is not always a given with cheap tech gadgets. However, during the touch test, the low price becomes noticeable. The charging case and the stick-style earbuds are made of a rather simple, very lightweight hard plastic. Fortunately, there are no sharp edges or rough burrs (no safety risk), but the cool premium feel of aluminum is nowhere to be found here.

Performance and practical test

The setup is completely intuitive and requires no glance at the manual thanks to Google Fast Pair. In the acoustic stress test, the EarFun Air Pro 4 makes the premium competition sweat:

• Sound & Codecs: They support both LDAC and aptX Lossless (Snapdragon Sound). This combination for under 100 euros is still an absolute rarity in 2026 and delivers an extremely high-resolution, clear sound with punchy bass.
• ANC (worst-case scenario): In a noisy subway, the adaptive noise cancelling (up to 50 dB) filters out deep background noises surprisingly well.
• Battery & cleaning: The battery life is outstanding at up to 11 hours (without ANC) or 7.5 hours (with ANC). The case even supports wireless charging (Qi). The smooth silicone tips are also very easy to clean under running water or with a cloth. Another highlight is the Auracast support (via Bluetooth 5.4), which allows you to tap into public audio streams.

The "Do Not Buy" recommendation (honesty)

Where's the catch at this price? Clearly with the microphones in noisy environments. In a quiet office, phone calls are perfectly fine. However, standing on a busy street or in strong wind, the software suppression kicks in so aggressively that your own voice sounds heavily distorted, metallic, and sometimes unintelligible. Not suitable for: Business users who need to make long calls outdoors daily, as well as users for whom headphones should be a visual status symbol.

Conclusion and price-performance ratio

"Would I recommend this product to my best friend if he has exactly the described problem?" A clear yes! If he owns a current Android smartphone and is looking for the ultimate price-performance winner, there’s hardly a better choice. Launched at an MSRP of around 90 euros, the street price for the EarFun Air Pro 4 in April 2026 is often between 60 to 70 euros (often even cheaper through Amazon coupons). For this money, the offered tech flood is an absolute dream.
