OPPO Enco Air 4 is a high-quality, affordable TWS headset, with a beautiful design, long battery life and excellent sound quality, suitable for users who need a convenient and effective daily music device.
1. Design and ergonomics
Earphone OPPO Enco Air 4 has an exterior design that is almost indistinguishable from the Enco Air 4 Pro version, at least in appearance. The headphones are made from glossy, smooth plastic, giving a luxurious feel. The finishing quality of the charging box is very good, the hinges are sturdy, there are no loose or creaking sounds. The parts of the headset are also meticulously and skillfully assembled.
A significant plus point is that OPPO Enco Air 4 meets IP55 dust and water resistance standards (headphones only), ensuring durability and tolerance in daily use conditions.

The charging box is equipped with a USB-C port, connection button and LED light to display battery status. The magnet inside the box holds the headphones firmly, although the surface of the headphones is a bit slippery, taking the headphones out of the box is still easy. The headphones are clearly marked L/R. The touch surface is designed to be slightly concave, making it easy for users to operate. The microphone is integrated on the body of the headset. However, the product lacks a proximity sensor, meaning the headphones will not automatically pause music playback when removed from the ear.
Like the Enco Air 4 Pro, the Enco Air 4 fits close to the ear, providing a comfortable and sturdy feeling that does not cause discomfort during long use.
2. Connectivity and compatibility
Thanks to support for Google Fast Pair technology, OPPO Enco Air 4 wireless headphones are recognized and paired quickly by Android smartphones with just opening the box. For other devices such as iPhones or Windows computers, pairing needs to be done via Bluetooth settings. The headset supports multipoint connection, allowing users to connect to two devices simultaneously and easily switch between them without disconnecting and re-pairing.
3. HeyMelody application
On both Android and iOS operating systems, OPPO Enco Air 4 true wireless headphones work with the HeyMelody application. The application has an intuitive, easy-to-use interface. Users can check the battery level of the headset and charging case, enable/disable ANC or transparency mode, customize touch operations, and enable low-latency gaming mode. However, a small minus point is that the application lacks a full equalizer, only providing 3 preset options, affecting the output sound quality.
4. Sound and performance
OPPO Enco Air 4 bluetooth headset delivers impressive sound quality. The mid and high tones are presented clearly and clearly. The overall sound is detailed and clean. The bass range is slightly more prominent than other sound ranges, but users can adjust it through the equalizer on Android devices. The headset has a fairly high volume, but users should keep the volume level at about 65-70% to protect their hearing.

The soundstage is spacious and the sound positioning is accurate. The touch surface is sensitive and easy to use, does not cause discomfort or cause the headset to fall out when operating. Users can customize touch operations, including pause/play music, skip songs, and adjust volume (this feature needs to be enabled in the HeyMelody app).
5. Microphone and active noise cancellation (ANC) performance
OPPO Enco Air 4 allows for clear calls, even in outdoor environments. However, the microphone can still pick up loud noises such as wind. Active noise cancellation (ANC) is effective at 32dB, lower than the Enco Air 4 Pro (49dB). Therefore, the noise cancellation ability of this headset is average, only slightly reducing noise in urban or noisy environments. vacuum cleaner. However, at this price range, this is an acceptable result.
6. Battery life
According to the manufacturer, the OPPO Enco Air 4 headset has a battery life of up to 8 hours when ANC is turned on and 12 hours when ANC is turned off. When used with the charging case, the total battery life is up to 23 hours (with ANC) and 43 hours (without ANC). These numbers are based on playing music at 50% volume.

During actual use, you cannot drain the headphone battery in a week if you only use it for a maximum of 3 hours at a time. OPPO confirms that the Enco Air 4’s battery will retain more than 80% of its original capacity after 4 years of use. The headphones are charged via the magnetic charging case, and the charging case only supports wired charging. The time to fully charge the headphones is 65 minutes and the time to fully charge both the headphones and the charging box is 90 minutes.
7. Conclusion
The OPPO Enco Air 4 true wireless headset is a worthy choice if you are looking for a cheap wireless headset with good sound quality and comfortable to use. However, users need to consider spending more money to buy Enco Air 4 Pro with better ANC features, proximity sensor and LHDC 5.0 codec support. The market today also has many products in the same price segment from other brands such as Huaweiworth users’ reference.
