OPPO has officially introduced the Enco Free4 wireless earbuds, marking a significant advancement in their audio lineup. Each earbud is engineered with a 6mm planar tweeter and an 11mm bass driver, delivering a balanced and immersive sound experience that meets the high standards of audiophiles.
The Enco Free4 supports Hi-Res Wireless Audio through the LHDC 5.0 codec, operating at 192 kHz and 1 Mbit/s, ensuring superior audio fidelity. Equipped with dual DACs, these earbuds provide enhanced sound processing capabilities. Additionally, the spatial sound feature allows for precise customization of the soundstage, offering users a tailored listening experience.
A standout feature of the Free4 is its active noise cancellation (ANC) system, which can reduce ambient noise by up to 59 dB.

The earbuds intelligently switch between ANC and transparency modes based on the surrounding environment, seamlessly adapting to both quiet settings and noisy streets.
