Co-Created with Dynaudio

Advanced technology and decades of Northern European legacy come together in the Enco X earphones, co-created by OPPO and leading Danish HiFi brand Dynaudio, founded in 1977. To bring you digitally precise audio, we evaluated 30 different materials and 152 components, and went through 120 rounds of structural fine-tuning in collaboration with the largest acoustic laboratory of Dynaudio.

The DBEE 3.0 Sound System: Conquering New Frontiers

In 2007, OPPO first released its DBEE 1.0 Dynamic Audio technology. Now, 13 years later, we are introducing our brand new DBEE 3.0 Sound System with new materials, new technologies, and a new structure.

Coaxial Dual-Driver Design

An innovation on traditional models, the Enco X earphones feature a coaxial dual-driver design typically only found in high-end audio devices. In the front, a magnetic balanced membrane driver handles high frequencies, and in the back, a triple-layer composite dynamic driver handles middle and low frequencies. Dual speakers positioned on parallel axes ensure natural and high-def audio output.

Magnetic Balanced, Membrane Driver

The Enco X earphones take the same technology as our innovative, award-winning PM-1 headphones, and fit it into an impressively small package. This design extends the reach of high frequencies, delivering crystal-clear audio.

Dual-Core, Dual-Mic Noise Cancellation

Thanks to a dual-core chip and a dual-microphone design, it improves the signal-to-noise ratio which optimises noise cancellation capabilities from every aspect3.

Flagship-Level Transparency Mode

Wish you could seamlessly switch between work and music? The Enco X earphones let you do just that, with a Transparency mode that gives you greater awareness of the surrounding environment. Youll be able to carry on a conversation without ever having to take your earphones off.

Natural Acoustics from Northern European Experts

Daniel Emonts, creator of Dynaudios flagship products, has brought 30 years of experience to the Enco X earphones. Years of acoustics research, craftsmanship, and hundreds of recalibrations have ensured that the Enco X earphones deliver nothing but sound in its truest form.

Earphones that Understand Your Ears

The Enco X earphones feature an innovative ergonomic design, a weight of only 4.8g, and silicone tips in two hardness levels, ensuring both stability and comfort.

15 Years in the Making

15 years ago, OPPO launched its first headphone product, the MP3 X3. Its star-ring design demonstrated a perfect union of technical skill and aesthetics. The Enco X earphones feature a revamped metallic star-ring frame designed to fit perfectly in the palm of your hand.

Binaural Low-Latency Bluetooth® Transmission4

Designed with strong interference scenarios in mind, Binaural Low-Latency Bluetooth® Transmission now features greater stability, system-level ultra-low latency optimisation, and even stronger latency reduction. In addition, we've significantly improved audiovisual synchronisation and further reduced lagging and connection interference.

Triple-Microphone Call Noise Cancellation

Equipped with a triple-microphone noise cancellation algorithm, an adaptive filter, and wind detection, the Enco X earphones ensure that your voice is transmitted properly in calls.

Convenient Wireless Charging

The Enco X earphones support wireless charging it's as simple as placing the charging case on a charging pad. The earphones also support reverse charging from a phone, so you can continue listening to music while they charge.

Remarkably Long-lasting Battery Life

Enjoy up to 25 hours of music playback on one charge that's two whole weeks if used for 2 hours a day. Even on long trips, you won't need to pack your charging case. At last, "low-battery anxiety" can be a thing of the past.

All-Weather Protection

The Enco X earphones fear neither rain nor sweat. With IP54 dust and water resistance7, these earphones can accompany you through heavy wind, rain, and workouts alike.

Convenient Touch Controls

Additional controls are available and are customisable through the app8. Controlling your earphones has never been so easy. Skip to the next song, Answer/hang up the phone: Double tap the earphones. Toggle noise cancellation mode: Press on the earphones for 1s. Turn volume up or down: Slide your finger up or down.

Quick Connection, Fit Detection

Open the lid, pop the earphones out, and tap to connect it's that simple. The earphones will automatically reestablish connection and be ready for use before you even put them on. Our all-new Earbud Fit Test function detects how well the earphones fit your ears, ensuring not only comfort but also audio quality and noise cancellation results.
