Oppo Enco Free4 Debuts in China with 55dB ANC Technology
Singapore, April 14, 2025 – Oppo has just unveiled its latest true wireless earbuds, the Oppo Enco Free4. These new TWS earbuds come equipped with powerful Active Noise Cancellation (ANC) that can reduce noise by up to 55dB at a frequency range of 5500 Hz. The Enco Free4 can detect ambient noise 900 times per second and is TUV Rheinland certified for its noise cancellation performance.
One of the highlights is the adaptive ANC feature, which automatically adjusts based on the environment. Whether you're in a quiet room or walking through a busy street, the earbuds intelligently adapt to keep things comfortable and safe for everyday use. Oppo also brings high-quality audio to the table with Hi-Res Wireless Audio support through LHDC at 192kHz and 1Mbps, dual DACs, and 3D Spatial Audio for a truly immersive listening experience.
These earbuds go beyond just music. They are packed with real-time AI features like language interpretation, call summaries, and even face-to-face translation, making them ideal for travelers or busy professionals. With an IP55 rating, they’re also built to handle sweat and light splashes, so you can confidently use them during workouts.
Each earbud carries a 62mAh battery, offering impressive battery life. With ANC off, you can get up to 11 hours of playback on the AAC codec or up to 9 hours with LHDC. With ANC turned on, playback drops slightly to around 6 hours with AAC and 5.5 hours with LHDC. Total battery life with the case can stretch up to 45 hours, depending on your usage.
