Manufacturer: Oppo

The Oppo Enco Air 4 Pro are true wireless earbuds designed for everyday wireless listening, offering an in-ear fit with no cables or neckband. Rated IP55, they carry sweat and dust resistance suitable for active use, and each earbud weighs just 8.8 g, keeping things light during extended wear. The set includes a charging case that extends total playback to 44 hours combined, and fast charging is supported to help reduce downtime.

Sound performance is backed by a 12.4 mm driver unit covering a 20 Hz to 20,000 Hz frequency range, with active noise cancellation and passive noise isolation both present. Spatial audio support adds a wider soundstage, while six microphones with noise-canceling capability handle voice calls and voice input. On the connectivity side, Bluetooth 5.4 is paired with LDHC and AAC codec support, an audio latency of 47 ms, and a maximum wireless range of 10 m. Multipoint connection allows simultaneous pairing with two devices, and USB Type-C handles wired charging.

Pros

Active noise cancellation and passive noise reduction work together to limit ambient sound during use
Six microphones with noise-canceling capability support cleaner voice pickup during calls
Multipoint connection allows simultaneous pairing with two devices at once
The charging case extends total battery availability to 44 hours combined, with fast charging supported
Ambient sound mode, in-ear detection, find device, and mute function cover a wide range of day-to-day usability needs
IP55 rating provides resistance to sweat and dust, making the earbuds suitable for physical activity

Cons

Battery life drops to 5.5 hours when ANC is active, which is noticeably shorter than the standard 12-hour playback figure
Wireless charging is not supported, requiring a wired USB Type-C connection for recharging
No aptX codec variants are available, limiting high-quality audio options for devices that rely on that codec family
Maximum Bluetooth range is capped at 10 m, which restricts usability when moving away from the paired device
Fast pairing and NFC-based pairing are both absent, making the initial connection process more manual

Who is this for?

These earbuds are a solid fit for users who commute, exercise, or spend time in noisy environments, thanks to the combination of active noise cancellation and IP55-rated sweat resistance. The six-microphone setup with noise-canceling capability makes them well-suited for frequent voice calls or remote work scenarios where clear voice pickup matters. Users who regularly switch between two devices will also benefit from multipoint pairing, while the 44-hour combined battery capacity with fast charging support suits those who need reliable all-day use without frequent interruptions.

Who is this NOT for?

Users who prioritize high-resolution wireless audio through codecs like LDAC or aptX HD will find the options here limited, as none of those formats are supported beyond LDHC and AAC. The ANC battery life of only 5.5 hours may not satisfy listeners who rely heavily on noise cancellation throughout a full working day. Additionally, those who prefer a hands-free or completely wireless charging setup will be inconvenienced by the absence of wireless charging, and users who need extended freedom of movement may find the 10 m Bluetooth range restrictive in larger spaces.
