The OPPO Enco X4 wireless earbuds have officially launched with a retail price of ¥1199, while the initial promotional price is set at ¥1099. The device features a collaboration with Dynaudio to deliver high-fidelity lossless sound quality, supporting transmission rates up to 2.3Mbps and 48kHz/24bit audio specifications.
The hardware is built on a fourth-generation coaxial dual-driver structure with dual DAC frequency division.
