Acoustune HSX ONE Dynamic Driver Noise Cancelling ANC Bluetooth True Wireless Earphone with App Made In Japan

Premium HSX Sound in a More Accessible TWS Model
The previous HSX1001 featured a physically separated acoustic chamber and wireless module, allowing the use of a metal housing for the acoustic section.

While HSX One does not physically separate these two components, it incorporates design know-how derived from the HSX1001 architecture. The driver unit is housed in a precision CNC-machined metal enclosure, while the wireless module is integrated into a high-precision polycarbonate casing. These components are carefully engineered and used together to prevent mutual interference and preserve acoustic integrity.

Improved 3rd Generation Myrinx Driver Developed Exclusively for HSX One
HSX One features Acoustune’s proprietary "3rd Generation Myrinx Driver", also used in the flagship HSX1001.

Myrinx is a high-performance polymer biomaterial also used in artificial skin and surgical sutures. As a diaphragm material, it delivers exceptional acoustic characteristics. The 10mm Myrinx diaphragm, optimized for this driver structure, combines lightweight construction with high strength and flexibility. The result is high-resolution sound reproduction with excellent transient response and a wide dynamic range.

Because the internal structure of HSX One differs from the HSX1001, this model uses a dedicated Myrinx driver unit specifically tuned to match its back chamber volume. Particular attention has been given to low-frequency performance — an area susceptible to standing waves — to optimize both sound quality and noise-cancelling performance.

Active Noise Cancellation That Preserves the Acoustune Sound Signature
HSX One is the first Acoustune TWS model to feature Active Noise Cancellation (ANC).

By reducing ambient noise, ANC enhances immersion and allows listeners to fully experience the refined sound produced by the Myrinx driver across a wide range of environments. An Ambient Sound Mode is also included, enabling users to hear their environment when needed for safety and convenience.
