Product Description
OPPO Enco X4 are OPPO's flagship true wireless noise cancelling earbuds, launched in October 2026. They pair a Dynaudio-tuned dual-driver system with AI adaptive noise cancellation, lossless audio support and up to 53 hours of total battery life.
Sound tuned with Dynaudio
For the seventh year in a row OPPO worked with Dynaudio, spending more than 300 hours tuning every frequency band. The dual dynamic drivers, an 11mm woofer and a 6mm tweeter, each have their own DAC for deeper bass and clearer, more detailed highs.
Lossless audio
OPPO Enco X4 is OPPO's first TWS earbuds to support lossless audio transmission, at up to 2.3Mbps and 48kHz/24-bit using the LHDC codec. Full-chain lossless audio works with supported OPPO Find X10 series phones.
AI adaptive noise cancellation
A 6nm chip senses your surroundings, such as trains, taxis, streets and planes, and switches noise cancellation in real time. OPPO says overall noise cancellation is improved by 100% and voice noise reduction by 30%. Conversation Awareness lowers the volume and switches to Transparency Mode when you start speaking.
Clear calls
A bone conduction VPU picks up your voice at the source, and a triple-microphone array with an AI noise cancellation algorithm keeps your voice clear even in busy places.
Comfort and battery life
Redesigned low-strain ear tips in four sizes improve passive isolation and comfort. Each earbud weighs about 5.6 g and lasts up to 13 hours with ANC off, or up to 53 hours with the charging case.
Personal sound
Spatial audio with head tracking, a 10-band Sound Master EQ and Golden Sound, which tailors the sound to your ears, let you set up the sound the way you like it.
