OPPO announced the Enco X4 on 21 October 2026 in Palma as its latest flagship true wireless earbuds, emphasising a multi‑driver acoustic design, lossless wireless playback support and context‑aware noise cancellation. The company said the Enco X4 continues its collaboration with Dynaudio and adds features intended for commuting, travel and cross‑device listening.
Hardware and audio architecture
At the core of the Enco X4 is a new‑generation dual‑driver acoustic system that pairs an 11mm TRF diaphragm woofer with a 6mm planar diaphragm tweeter. OPPO said each driver is driven by a dedicated high‑performance DAC, creating a dual‑driver, dual‑DAC architecture intended to process different frequency ranges independently and deliver “more acoustic energy” and faithful sound reproduction across the frequency range. OPPO also detailed five exclusive sound profiles co‑tuned with Dynaudio to suit different music genres and listening preferences.
Lossless audio and spatial features
OPPO stated the Enco X4 is its first TWS to support lossless audio over wireless using LHDC Lossless when paired with the OPPO Find X10 Series. The company specified transmission rates of up to 2.3Mbps, enabling lossless playback at up to 24‑bit/48kHz. The earbuds are also Hi‑Res Audio Wireless certified. For immersive listening, OPPO is offering Cross‑Ecosystem Spatial Audio, which it said is available across Android, iOS and Windows devices to create a three‑dimensional soundstage for music and movies.
Intelligent noise cancellation and everyday features
For noise control, OPPO introduced an AI Adaptive ANC system that the company said intelligently adjusts active noise cancellation and transparency levels based on ambient noise and user preferences. The Enco X4 debuts a “new‑generation” noise cancellation system with Low‑Strain Noise‑Cancelling Ear Tips and a triple‑microphone array; the announcement highlighted these elements as part of improving comfort and call performance for commuting and travel.
