Detailed introduction

Product function/features

Jointly created by OPPO x Danner

Born in 1977, Dynaudio, a Nordic-class Hi-Fi brand, has created a legendary voice together with modern technology OPPO. In order to achieve digitally accurate sound performance, we develop it at the Dynaudio R&D center in Skanderborg. 30 kinds of material exploration, 120 rounds of structural modification, 152 device selections, all demanding is only for sound.

DBEE 3.0 sound system, bring Hi-Fi audio into your ears

In 2007, OPPO developed DBEE dynamic sound effects. 13 years later, we created a brand new "DBEE 3.0 sound system" with new materials, new structures, and new technologies.


Coaxial dual unit design, high, middle and low tri-band upgrade again

The breakthrough performance of OPPO Enco X uses the coaxial dual unit design in high-end audio. The initial superconducting magnetic plane diaphragm unit, the rear three-layer composite moving coil unit, the dual speakers are located on the same stripe, the sound output directly hits the soul, just for you to hear with your own ears.


Superconducting magnetic plane diaphragm unit, the favorite singer reappears in front of you

OPPO’s flagship flat-diaphragm headset PM-1 has won many international awards. This time we use its core technology to develop a miniature superconducting magnetic flat-diaphragm, which suspends the middle of the dual-row parallel magnetic circuit voice coil to suppress the diaphragm. Dividing the vibration, the high frequency that is as translucent as a diamond is instantly engraved.


Let you hear every audio track clearly, LHDC™ wireless transmission

LHDC™ high bit rate transmission, according to the traditional SBC, AAC transmission, can retain more sound details for you, so that every sound track is clearly expressed, every note is full and thorough, and the rhythm can also be reached at your fingertips.
OPPO mobile phone users can follow the path below [Settings-Sound and Vibration-Dolby Atmos-Music-Balance] to enable Dolby sound to get the best music experience.


Dual wheat dual-core noise reduction, one-key mute in the world

Using a double-fed microphone with a higher signal-to-noise ratio and a new dual-core chip, the noise reduction range from indoor to multi-layer, from home to travel, almost can be covered


Transparent mode listens to songs and talks, and it is natural

Want to seamlessly switch between work and music? No need to pick up the earphones, long press to quickly switch the transparent mode, the surrounding environment sound is collected in the ears, and directly say "Hi" directly on the earphones.


Master Tanner tunes the sound and makes it hard to listen to it after a long test

Daniel Emonts, with 30 years of professional audio work experience, is the creator of Dynaudio's flagship audio series, and works with the OPPO acoustic team to tune the headphones.
As Daniel said, "Every detail is important", OPPO Enco X uses science to create a true natural sound from front and rear sound chambers, tuning materials, and dual-unit crossover design.


Lightweight and comfortable, give the ear a massage

The new headphone fit detection technology can effectively remind you to adjust the position to ensure the best sound quality and noise reduction.
Innovative ergonomic design, silicone double-hardness ear caps, each ear is ultra-lightweight of only 4.8 grams, listening while jumping, lying down, walking and listening, you can listen to whatever you want.


Design reunion spanning 15 years

15 years ago, OPPO launched the first MP3 X3. The classic star ring design reached a consensus on technology and aesthetics; 15 years later, we brought new inspiration to the classic design. The new design of the star ring metal frame fits the circle of the palm better. Arc design, you can't put it down when you get started.


Bluetooth 5.2 low-latency dual transmission, more stable restart and smoother

System-level ultra-low latency optimization, greatly reducing sound delay, significantly improving the use of mid-range audio and video synchronization, game freeze, interference and disconnection problems. When playing mobile games or audio-visual entertainment, the smooth sound is a matter of course.
