OPPO has launched its latest wireless earbuds, the Enco Free 4. This new model offers a range of advanced features, including active noise cancellation (ANC), water and dust resistance, gesture controls, and extended battery life. The Enco Free 4 is an in-ear style earbud with a stem design and comes in two color options. The earbuds are housed in a rounded charging case featuring the OPPO logo. Each earbud includes three microphones and utilizes artificial intelligence (AI) to enhance voice isolation during calls.
One of the key highlights is the 55dB active noise cancellation, which works alongside real-time noise detection at a rate of 800 times per second. This allows for a reported 200% improvement in human voice suppression. The earbuds are equipped with Bluetooth 5.4 for improved connectivity and also support gesture-based controls. The device holds an IP55 certification, confirming its resistance to water splashes and dust. Additionally, it has received TÜV Rheinland certification for battery reliability.
In terms of battery life, each earbud is equipped with a 62 mAh battery, while the charging case contains a 530 mAh battery. OPPO claims that with ANC turned off, users can enjoy up to 45 hours of total usage when using the charging case. A single charge delivers up to 11 hours of use, depending on feature usage. Charging the earbuds takes approximately 50 minutes, while the case requires around 80 minutes.
