Oppo has launched its Enco X4 earbuds for international markets following an initial release in China in September 2026. The audio hardware features a dual-driver system and an onboard 6nm NPU for real-time noise environment adaptation.
Why it matters
The international rollout expands the availability of hardware-accelerated noise cancellation in the mid-range audio market. By integrating a dedicated 6nm NPU into earbuds, Oppo is pushing more complex processing to the edge to manage varying acoustic environments.
The Enco X4 utilizes an 11mm woofer and a 6mm tweeter to handle a broad frequency range. The system achieves 53 hours of total battery life, supported by a 6nm NPU that processes audio inputs for active noise control.
The players
Oppo
A consumer electronics company known for its mobile devices, wearable audio gear, and proprietary AI hardware integration.
The details
The earbuds employ a dual-driver architecture, separating low-frequency sound production through the 11mm woofer from high-frequency audio via the 6mm tweeter. A 6nm NPU — a specialized neural processing unit designed for efficient artificial intelligence tasks — continuously monitors external soundscapes to adjust noise cancellation profiles. Four microphones per earbud and a bone-conduction voice pick-up unit, which captures vibrations directly from the skull to isolate speech, work in tandem to improve call clarity.
Timeline
September 2026: Oppo Enco X4 earbuds were released in China.
October 2026: The Enco X4 earbuds launched in international markets.
The Tech Race
The integration of a 6nm NPU into the Enco X4 represents an effort to match the processing capabilities of dedicated audio chips like the Apple H2. As manufacturers push for better noise isolation, the focus has shifted toward high-efficiency, on-ear silicon that can perform real-time DSP tasks.
The earbuds are now available in the UK for £189 and across Europe for €199, offering compatibility with standard mobile device ecosystems via wireless and USB-C charging. Squeeze controls on the stems provide the primary interface for managing playback and switching between noise cancellation modes.
The takeaway
Oppo is betting that onboard neural processing will provide a competitive edge in audio clarity for mid-range wireless earbuds. Consumers should watch for real-world benchmark tests to see if the 6nm NPU delivers tangible improvements over standard active noise cancellation systems.
