Oppo Enco Free 4: Introduced with ANC technology!

Oppo has introduced its new wireless earbuds — Enco Free 4, featuring 55 dB Active Noise Cancellation (ANC), Hi-Res audio quality, and AI-powered translation features. The device is now available for pre-order in China, with official sales starting on April 16.

With an impressive 5500 Hz frequency range, Oppo Enco Free 4 delivers top-tier sound performance. Its noise-cancellation system detects ambient sounds 800 times per second and reduces voice noise by up to 200%, creating an immersive listening experience.

Features and design of Oppo Enco Free 4

Each earbud includes three separate microphones — feedforward, feedback, and call mic — working in harmony with AI algorithms to ensure crystal-clear call quality. Thanks to smart environmental sensors, the earbuds automatically switch between ANC and transparency modes depending on your surroundings.

The Premium Star Ceramic Silver version, specially tuned by audio experts from Dynaudio, delivers a unique sound signature. With a 11 mm bass driver and 6 mm planar tweeter, LHDC 5.0 codec, and support for Hi-Res Wireless Audio (192kHz, 1Mbps), users enjoy a rich and spatial 3D sound experience. Dual DAC and ear canal-based sound calibration enhance the overall listening effect.

AI-powered capabilities

The earbuds support real-time translation, call summarization, and come equipped with Bluetooth 5.4, ensuring stable connections up to 400 meters — even in signal-dense environments like train stations. Oppo devices can automatically transfer audio content between each other.

With an ergonomic design and lightweight build (only 4.7g per earbud), Enco Free 4 is ideal for long-term use. Certified with IP55 for dust and water resistance, the earbuds feature 62 mAh batteries, while the case holds 530 mAh. Battery life is up to 11 hours without ANC, or 45 hours with the charging case. With ANC on, this drops to 6 and 24 hours, respectively.

The Oppo Enco Free 4 is available for pre-order in China. The Star Ceramic Silver model is priced at 449 yuan (~$61), while the Water Blue version is 399 yuan (~$55).
