OPPO Enco X4 Launched in China With Lossless Audio and AI Translation
OPPO has launched the Enco X4 true wireless earbuds in China on September 22, 2026, alongside the new Find X10 smartphone series. The new earbuds focus on high-quality audio, stronger noise cancellation, spatial audio and AI-powered features.
The Enco X4 also introduces a fourth-generation dual-driver audio system developed with Dynaudio, while OPPO has upgraded the internal chip from a 12nm process to 6nm.
OPPO Enco X4 launch: Key Highlights
The Enco X4 is positioned as OPPO’s flagship wireless earbud offering. It comes with an in-ear design and a compact charging case, with three China-market colours: Soft White, Pink Gold and Titanium Grey.
The main audio hardware combines an 11mm dynamic driver and a 6mm tweeter. The earbuds also support Hi-Res Audio Wireless, lossless audio transmission and spatial audio.
OPPO says the Enco X4 can handle 48kHz/24-bit lossless audio, with transmission speeds reaching up to 2.3Mbps. The company has also worked with Dynaudio on the tuning.
Fourth-Generation Dual-Driver Audio
One of the biggest upgrades is the fourth-generation coaxial dual-driver system.
The earbuds use separate drivers for different parts of the audio range and a dual-DAC crossover architecture. OPPO says the design improves sound separation while reducing distortion.
The Enco X4 also includes several Dynaudio-tuned sound profiles, including Dynaudio Original Sound, High-Resolution, Pure Vocals, Clear Treble and Surging Bass.
OPPO claims a 50% increase in low-frequency driving force and a 20% reduction in full-frequency distortion compared with the previous generation, based on its laboratory testing. These figures should therefore be treated as company-reported results rather than independent test results.
AI-Powered Noise Cancellation
Noise cancellation is another major focus of the Enco X4.
The earbuds use a 6nm chip and an adaptive intelligent noise-cancellation system. OPPO has also introduced improved voice-noise reduction for calls.
According to OPPO’s launch information, the Enco X4 supports multiple noise-control modes and uses four microphones for calls. The company has also promoted two-way AI noise cancellation for noisy environments.
The earbuds are rated IP55 for dust and water resistance, giving them some protection against everyday exposure to dust and water.
AI Real-Time Translation
One of the more interesting additions is AI real-time translation.
OPPO says the Enco X4 can support translation across 24 commonly used languages. The feature is designed for conversations where one person can view translated text on a screen while the other person listens through the earbuds.
OPPO’s Chinese launch information says the system can work without requiring the phone to be physically passed back and forth between the two people.
The exact language availability and regional support can vary, so the 24-language figure should not automatically be treated as universal support in every market.
Battery Life
The Enco X4 offers up to 13 hours of playback from the earbuds alone under specified testing conditions, while total listening time with the charging case can reach 53 hours with ANC off and AAC playback.
With ANC enabled, battery life is lower. Reported figures include around six hours from the earbuds using AAC, while LHDC playback with ANC is rated at around 5.5 hours.
The charging case supports USB Type-C and wireless charging. OPPO also says a 10-minute charge can provide up to 4.5 hours of listening.
Bluetooth 6.1 and Dual-Device Connectivity
Connectivity has also received an upgrade.
The Enco X4 supports Bluetooth 6.1, along with AAC, SBC, LHDC and LC3 codecs. It can connect to two devices simultaneously, making it possible to switch between devices without repeatedly disconnecting and pairing.
The earbuds are compatible with both Android and iOS devices, although some advanced features may depend on the OPPO/ColorOS ecosystem and companion software.

OPPO Enco X4 Price and Availability
In China, the OPPO Enco X4 has a recommended retail price of CNY 1,199, while the initial promotional price is CNY 1,099. Pre-orders began around launch, with shipping reported to start on September 24.
OPPO’s ecosystem website now lists the Enco X4 as part of its official earbud lineup.
International availability is separate from the China launch. OPPO has already referenced the Enco X4 in a UK Find X10 launch promotion, including a 30% discount coupon for the earbuds during a later promotional period, indicating that an international rollout is planned in at least some markets.
However, India pricing and availability should not be assumed from the Chinese launch price until OPPO announces them for the Indian market.
Why the Enco X4 Matters
The Enco X4 is more than a routine upgrade to OPPO’s wireless earbuds.
The combination of dual-driver audio, lossless transmission, Dynaudio tuning, adaptive ANC, spatial audio and AI translation shows how premium earbuds are increasingly becoming small computing devices rather than simply Bluetooth headphones.
The AI translation feature is particularly notable because it moves the earbuds beyond music and calls into communication. At the same time, features such as head gestures, voice commands and stereo recording add additional interaction options.
Conclusion
The OPPO Enco X4 arrives as a feature-heavy flagship TWS model built around lossless audio, Dynaudio tuning, dual-driver hardware, adaptive ANC and AI translation.
Its China launch price starts at CNY 1,099 during the introductory period, while international availability is being expanded separately. For Indian buyers, the next important announcement will be OPPO’s official India pricing and launch details.
