Oppo has officially unveiled its latest true wireless earbuds — the Enco X3s — blending premium audio performance with cutting-edge smart features.
The new earbuds bring a compelling mix of advanced Active Noise Cancellation (ANC), dual-driver audio architecture, and AI-powered live translation, making them one of the most feature-rich entries in Oppo’s growing lineup of wireless earphones.
Powerful 55dB Active Noise Cancellation
The Oppo Enco X3s are designed for immersive listening even in noisy environments. The earbuds feature adaptive hybrid ANC capable of reducing noise by up to 55dB, covering a broad frequency range up to 5,500Hz.
Dual Drivers for High-Fidelity Sound
Inside each earbud, Oppo has fitted two dynamic drivers — an 11mm driver for deep bass and a 6mm driver for crisp mids and highs. Together, they reproduce sound across a wide frequency spectrum of 15Hz to 40kHz.
For audiophiles, the inclusion of LHDC 5.0 codec ensures lossless, high-resolution wireless audio, while standard AAC and SBC codecs maintain compatibility with most smartphones and tablets.
Long Battery Life and Durability
Battery life is another highlight of the Enco X3s. With ANC off, users can enjoy up to 45 hours of playback using the charging case. Even with ANC and LHDC enabled, the earbuds manage a respectable 5.5 hours on a single charge.
The earbuds also boast an IP55 rating, making them resistant to dust and water — perfect for workouts or outdoor use.
Smart Features and Connectivity
Oppo is also introducing an AI-based live translation tool, allowing real-time language interpretation through connected Oppo devices. However, this feature remains exclusive to select Oppo smartphones for now.
The earbuds support dual-device connectivity, making it easy to switch between, say, a laptop and a phone without manual re-pairing.
While spatial audio support is present, Oppo has confirmed that head tracking is not included — a feature often reserved for more premium headsets.
