Oppo has launched the Enco Air 4i in China, a budget-friendly pair of true wireless earbuds that look like an upgraded version of last year’s Enco Air 4. They’re priced at just 99 yuan (around $14) and will be available on JD.com starting February 24.

Oppo Enco Air 4i Specifications
Despite the low price, the Enco Air 4i packs some solid features. It’s equipped with a 12.4mm dynamic driver for deeper bass and clearer audio, along with Oppo’s custom EQ tuning and spatial audio support for a more immersive sound experience.
Battery life is a major selling point, with the earbuds offering up to 12 hours of playback on a single charge and up to 54 hours with the charging case. If you’re in a rush, a quick 10-minute charge gives you four hours of listening time. Oppo has also secured TÜV Rheinland certification for battery durability, ensuring the earbuds can handle 1,000 charge cycles without significant degradation.
For connectivity, the Enco Air 4i supports Bluetooth 5.4, dual-device pairing, and a low-latency mode with 47ms response time, which should make them a decent choice for gaming. Pairing is also seamless with compatible Oppo devices.
Durability-wise, the earbuds come with an IP55 rating for dust and water resistance, so they should survive workouts and light rain. Oppo says they’ve been tested to withstand drops from 1.8 meters for the earbuds and 1.5 meters for the case, along with extreme temperatures up to 75°C.
Other handy features include customizable touch controls, AI voice assistant support, and a “Find My Earbuds” function through the companion app. You can also use gesture-based tap controls to manage playback, take calls, and even snap photos remotely.
As for design, the Enco Air 4i keeps things compact and lightweight. Each earbud weighs just 4.3g, while the case measures 59.2 x 24.0 x 47.5mm. It charges via USB-C and packs a 560mAh battery, with each earbud carrying a 58mAh cell.
These earbuds are available in Porcelain White and Obsidian Black.
