OPPO has launched the Enco Free 4 earbuds in China. They come with active noise cancellation up to 55dB, covering a 5500Hz frequency range. The earbuds detect noise 800 times per second, which helps reduce human voice interference by 200%. The ANC is TÜV Rheinland certified.

There are three microphones on each earbud—feedforward, feedback, and call mic. These work with AI to improve voice clarity during calls. The earbuds adjust ANC or transparency modes automatically depending on your surroundings, like quiet rooms or busy streets.

The Star Ceramic Silver version includes sound tuning by Dynaudio. The audio setup includes an 11mm bass driver and a 6mm planar tweeter. The earbuds support Hi-Res Wireless Audio through LHDC 5.0 (192kHz, 1Mbps), use dual DACs, and offer spatial audio with ear canal-based tuning.

Smart features include real-time translation, call summaries (triple-tap to activate), and face-to-face interpretation. Bluetooth 5.4 provides a 400-meter range and works well even in crowded places like train stations. The earbuds can also switch audio automatically between OPPO devices, like phones and tablets.

Each earbud weighs 4.7g and is IP55-rated for dust and water resistance. They include a 62mAh battery each, and the case holds 530mAh. Battery life depends on the codec and ANC usage:

• AAC Codec:
  • ANC off: 11 hours (buds), 45 hours (with case)
  • ANC on: 6 hours (buds), 24 hours (with case)
• LHDC Codec:
  • ANC off: 9 hours (buds), 37 hours (with case)
  • ANC on: 5.5 hours (buds), 22 hours (with case)

Charging takes about 50 minutes for the earbuds and 80 minutes for the case using USB-C. A companion app supports battery status, ANC controls, spatial audio, game mode, dual-device pairing, theme settings, and find-my-earbud features.
