The Oppo Enco Air4 Pro present themselves as mid-range true wireless earphones, with an attractive design and a series of interesting features, including active noise cancellation and long battery life. They feature a short-stem design with an ergonomic shape that fits well over the ear cup. The earbuds are made of plastic with a glossy finish, weighing just 4.4 grams each. This is a semi-in-ear design, which contributes to comfort and fit by reducing the feeling of pressure inside the ear. The charging case, however, is made of matte plastic and has a compact oval shape, with a total weight of 47 grams. The case lid opens and closes easily with one hand.
The Enco Air4 Pro features 12.4mm dynamic drivers with titanium-plated diaphragm, which promise high-quality audio reproduction with powerful bass and detailed sound. The earphones support AAC, SBC and LHDC 5.0 codecs, ensuring good compatibility with different devices and high-fidelity audio transmission, especially with Oppo devices that support LHDC 5.0. Bluetooth 5.4 connectivity ensures a stable, low-latency connection. One of the strong points of these earphones is the ultra-wide band active noise cancellation (ANC), certified by TÜV Rheinland for high performance.
Noise cancellation reaches a maximum depth of 49 dB and a sampling rate of up to 4000 Hz, meaning it can effectively attenuate a wide range of ambient noises, from traffic sounds to office buzz. Noise cancellation technology automatically adapts to your surroundings, switching from Max mode for noisier environments to Mild mode for quieter ones, always ensuring the optimal level of noise cancellation. There’s also Transparency mode, which allows you to listen to ambient sounds without having to remove the earphones, useful for quick conversations or maintaining awareness of your surroundings when walking down the street.
To ensure maximum clarity during calls, the Oppo Enco Air4 Pro uses a triple microphone system with digital microphone. This system can distinguish the human voice from ambient noise, effectively suppressing background noise and ensuring clear calls even in noisy environments. Another interesting feature is Dual Connection, which allows you to connect the earphones to two devices at the same time, for example a smartphone and a tablet. This function is very useful for those who use earphones with multiple devices, as it allows you to switch from one device to another without having to disconnect and reconnect.
The Enco Air4 Pro offer up to 12 hours of battery life on a single charge and up to 44 hours with the charging case. This is a longer battery life than the average for true wireless earphones in the same price range, which generally stands at around 20-30 hours. Fast charging allows you to get up to 4 hours of playback with just 10 minutes of charging, ideal for those who need a quick charge before leaving home. The audio quality of the Enco Air4 Pro is generally good, with detailed sound and smooth bass. 12.4mm drivers deliver dimensional sound with powerful bass. The midrange is crisp and clear, while the highs are crystal clear. Support for the LHDC 5.0 codec allows you to better appreciate high-resolution audio quality, with greater fidelity and less loss of detail.
The OPPO Enco Air4 Pro are light and comfortable to wear, thanks to their ergonomic shape and low weight. The presence of different sizes of ear tips allows you to find the right fit for each user. The earphones anchor firmly to the ear and do not move during use, even during physical activity. The HeyMelody application offers various features to personalize the experience of using the Enco Air4 Pro. Through the application, it is possible to customize the touch controls of the earphones, assigning different functions to single, double and triple touches, adjust the equalization of the sound, choosing between several preset modes or creating a custom profile, activate the low latency gaming mode, which reduces audio delay for a better gaming experience, perform an earphone fit test to verify the correct fit, and of course update the earphones firmware.
The Oppo Enco Air4 Pro are mid-range true wireless earphones that offer good value for money, given that they are currently sold for 80 euros. Audio quality is generally good, with powerful bass and detailed sound, although some users may find the bass excessive in certain music genres. They are a valid option for those looking for versatile and complete earphones, with a good balance between audio quality, functionality and price.
