OPPO Enco X ETI51 Headset True Wireless Noise Cancelling Earphones - White - ETI51 White

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.
