New Oppo Enco X4 Available in Three Colours

In terms of design, the Enco X4 retains the familiar stem-style earbud design. The earbuds will come with a compact, rounded charging case that features Oppo branding.

The earbuds have been shown in promotional images in three colour options: Pink Gold, Soft White and Titanium Gray. The charging case also follows a rounded and compact design.

The overall design continues Oppo's focus on a lightweight and modern appearance. The three colour options are expected to give users more choices based on their personal preferences.

Major Improvement in Noise Cancellation

Oppo claims that the Enco X4's ability to reduce human voice noise has increased by up to 250% compared with the previous generation. The company also claims that overall environmental noise reduction has improved by up to 200%.

The earbuds use a 6nm flagship-level chip along with an AI model-based noise cancellation algorithm. Oppo has also introduced AI-powered noise cancellation for calls.

According to the company, the technology can help maintain voice clarity even when surrounding noise levels reach up to 110 decibels. This could make the Enco X4 particularly useful for calls in busy or noisy environments.

New Audio Technology With Dynaudio

For audio performance, the Enco X4 features an advanced coaxial dual-driver system developed with the fourth-generation Dynaudio technology. The setup is also paired with a dual DAC.

Oppo claims that audio distortion across the frequency range has been reduced by 20% compared with the previous generation. The company says this is aimed at delivering clearer and more accurate sound.

The improved audio system is expected to enhance the listening experience for music, videos and other supported audio content. The collaboration with Dynaudio is also a key part of Oppo's focus on audio quality.

Audio Transmission Rate Increased by Up to 400%

The Enco X4 supports lossless audio transmission. Oppo claims that its audio transmission rate has increased by up to 400% compared with the previous generation.

The higher transmission rate is designed to retain more audio information when used with compatible devices and supported content. This could result in improved audio quality for users.

The combination of lossless transmission and the upgraded audio hardware is expected to be one of the major highlights of the Enco X4.

AI-Powered Real-Time Translation

One of the most interesting features of the Enco X4 is its AI-powered real-time translation capability. The feature is designed to help translate conversations when two people are speaking different languages.

The translation feature will work through a connected smartphone. AI technology will be used to process and translate conversations between different languages.

Alongside audio improvements, noise cancellation and call clarity, the real-time translation feature gives the Enco X4 an additional AI-focused capability. More information about its supported languages and detailed functionality is expected to be announced after the global launch.
