UGREEN has officially launched the Hitune T9 True Wireless Earbuds with Active Noise Cancellation. Co-developed and manufactured by AncSonic and UGREEN, the Hitune T9 features acoustic optimizations across active noise cancellation, call clarity, and spatial audio.

The Hitune T9 supports adaptive active noise cancellation, with a claimed maximum noise reduction of up to 60 dB. Its noise cancellation system performs up to 384,000 detection operations per second, enabling it to adjust its noise cancellation strategy in response to changing environmental conditions. For clearer calls in challenging acoustic environments, the T9 features a six-microphone array combined with two VPU bone-conduction sensors. By capturing voice-related vibrations through bone conduction and combining these signals with multi-microphone pickup and call noise reduction algorithms, the system enhances voice pickup in noisy environments.

For audio performance, the T9 features a custom-tuned 11 mm dynamic driver with a diamond-like carbon (DLC) composite dome diaphragm. It supports Hi-Res Audio and LDAC high-resolution audio transmission. The earbuds also incorporate AncSonic's proprietary SORC Spatial Audio algorithm, which processes and renders spatial sound fields to create a more immersive listening experience.

During development, AncSonic conducted systematic R&D focused on the product's acoustic architecture. Through multiple rounds of parameter optimization, system-level integration and tuning, and scenario-based validation, the team refined the interactions between different acoustic functions to ensure effective coordination across the complete device. This process helped translate acoustic technologies into a fully integrated consumer product.

The launch of the Hitune T9 marks another milestone in AncSonic's continued development of acoustic technologies and their practical applications. Drawing on its technical expertise and project experience, AncSonic continues to collaborate with industry partners throughout the product development process—from acoustic solution design and system-level tuning to mass production and delivery—bringing acoustic innovations into real-world products.
