Oppo Enco X4 Leaks with AI Real-Time Translation and Upgraded ANC

Oppo is preparing to refresh its flagship audio lineup with the Oppo Enco X4, the direct successor to the critically acclaimed Enco X2 and Enco X3 series. Key specifications, interface screenshots, and regulatory certifications have surfaced via Chinese tipster Digital Chat Station and international compliance databases, detailing an acoustic redesign, refined noise cancellation algorithms, and integrated machine learning tools.

Moving beyond conventional sound reproduction, the upcoming true wireless earbuds will introduce native AI real-time two-way translation, allowing users to conduct multi-language conversations directly through the earbuds with live transcriptions synced to connected ColorOS devices.

30-Second TL;DR

• Core Leak: Leaked firmware strings, UI screenshots, and regulatory filings have revealed the Oppo Enco X4 ahead of an expected launch alongside the Find X10 series.
• Real-Time AI Translation: Features integrated two-way translation (demonstrated between English and Simplified Chinese) with dual-speaker audio playback and live on-screen text.
• Acoustics & ANC: Continues Oppo’s tuning partnership with Danish specialist Dynaudio, featuring upgraded coaxial dual drivers and wider-band Active Noise Cancellation.
• Regulatory Clearance: Officially approved by the UAE’s Telecommunications and Digital Government Regulatory Authority (TDRA) under model number ETEM2.
• Battery & Power: Expected to deliver up to 48 hours of total playback (with charging case), alongside Qi wireless charging and USB-C fast charging.
• Ecosystem Launch: Slated to debut at Oppo’s upcoming autumn product keynote, with expected Indian retail pricing around ₹11,999.

Real-Time AI Conversational Translation: Breaking Language Barriers

The standout software addition on the Enco X4 is a native AI Real-Time Translation engine:

• Two-Way Voice Processing: Rather than acting solely as passive audio receivers, the earbuds capture spoken dialogue, process phrases through on-device and cloud LLM models, and output real-time translated speech back into the listener’s ear canal.
• Interactive Split-Screen UI: Leaked companion app screenshots illustrate an interactive dialogue mode. When chatting with someone speaking a foreign tongue (such as English to Simplified Chinese), the connected smartphone displays a split conversational window with independent playback toggles for both speakers.
• Conversational History: Translated dialogue is converted into structured text logs within the phone’s notes app in real time, making the earbuds a practical business and travel interpreter.

Upgraded Dynaudio Dual Drivers and Enhanced ANC Architecture

Acoustic performance remains centered on Oppo’s collaborative engineering with Danish audiophile firm Dynaudio:

• Coaxial Dual-Driver System: The Enco X4 is tipped to feature an upgraded concentric acoustic layout-pairing an 11mm composite dynamic bass woofer with a balanced planar diaphragm tweeter to separate sub-bass punch from ultra-high frequency airiness.
• Wider-Band Active Noise Cancellation: Building on the 50dB+ noise attenuation of previous iterations, the X4 upgrades its multi-microphone feedback/feedforward array to suppress a wider spectrum of mid-to-high frequency human vocal chatter and high-speed transit wind noise.
• Hi-Res Wireless Transmission: Supports LHDC 5.0 and LDAC lossless audio codecs, offering 24-bit/192kHz audio streaming over low-latency Bluetooth pipelines.
