7 sensors flagship-level deep noise reduction

It uses six microphones and an air pressure sensor to accurately capture ambient sounds from multiple angles and perform coordinated noise reduction. Equipped with a newly added air pressure sensor, it responds to changes in air pressure such as when flying on an airplane, and achieves deep noise reduction in all scenarios.

Adaptive ANC 3.0 environmental adaptive noise reduction technology

Based on the user's changing environment, 3 million calculations per second are performed and the noise reduction curve is readjusted every 0.3 seconds, providing three times* more effective noise reduction, ensuring a powerful and seamless noise reduction effect.

ACAA 4.0™ for ultimate sound quality

Inheriting the soundcore's coaxial dual-unit vocal design, it uses a 10.5 mm woofer and a 4.6 mm titanium alloy tweeter, combined with dual-channel audio technology (digital crossover technology), to clearly produce high-fidelity, unrendered sound. Hi-Res Wireless certified, corresponding to LDAC high-quality audio transmission technology, reproducing music details.

360-degree surround audio experience

Through soundcore's spatial audio algorithm, the dynamics of the head are tracked and calculated in real time to achieve an immersive experience like being in a movie theater. Four new modes are available: "Music", "Movie", "Radio" and "Game".

Smart charger for easy control and management

The charging box is equipped with a touch bar and display screen. You can easily adjust the noise reduction intensity by sliding, and check the battery information at any time. The glossy version allows you to view the display inside the charging box when the lid is closed.

Ultra-fast charging, always ready

Using 5C fast-charging battery, the earphones only need to be charged in the charging box for 5 minutes to provide up to 4 hours of music playback time. The earphones can be used for up to 10 hours on a single full charge with ANC mode off, and a total of 40 hours with the charging case. When ANC mode is turned on, the earphones can be used for up to 7.5 hours, and a total of up to 30 hours with the charging case.

6-microphone call experience

Using a total of 6 microphones and AI noise reduction algorithm, it can accurately pick up sound and convey the sound clearly.

Switch connections easily

Using Bluetooth 5.3 version, it supports connecting two devices at the same time and switching between them easily. Supports Google Fast Pair technology, connecting headphones is faster than ever.
