The Oppo Enco Air 5 Pro (model ETEL1) in Matte Black is a pair of wireless earbuds designed for a balanced listening experience. They feature 12mm drivers that deliver sound across a wide frequency range from 20 Hz to 40 KHz, supported by Bluetooth 6.0 and high-quality codecs like LHDC 5.0, AAC, and SBC for stable connectivity within a 10-meter range. These earbuds are built for long-term comfort and durability, weighing only 4.4g each and carrying an IP55 water resistance rating that protects them from dust and splashes. The Matte Black charging case provides significant power reserves. Depending on your settings, you can get up to 54 hours of total playback with ANC off using the AAC codec, or about 29 hours when active noise cancellation is enabled. A full charge for the entire set takes 90 minutes via the USB Type-C port, ensuring you spend less time plugged into a wall and more time listening to your music or taking calls.
