Acoustune HSX ONE True Wireless Bluetooth Earphones – Japanese Metal Chamber Design

Japanese Metal Acoustic Chambers for Everyday Hi-Res Listening

The Acoustune HSX ONE is a aJapan-made true wireless Bluetooth earphone that brings the brand’s renowned metal acoustic chamber technology into a compact, everyday TWS design. Combining a layered metal and polycarbonate housing, a newly tuned third-generation Myrinx 10 mm dynamic driver, and Hybrid ANC, HSX ONE delivers a premium balance of style, comfort, and high-resolution sound for daily music, calls, and travel.

Design Highlights & Build Quality

HSX ONE adopts an innovative one-piece layered structure, where a CNC-machined metal acoustic chamber (for the driver) is seamlessly integrated into a high-precision polycarbonate shell (for the wireless module). From the earpieces to the charging case, the design showcases a distinctive mechanical aesthetic with modern transparent styling. Each earbud features a physical button on the faceplate for accurate, tactile control without accidental touches.

Available in two finishes – Graphite (deep, refined urban grey) and Crystal (clear transparent) – HSX ONE blends Japanese craftsmanship with contemporary fashion, making it both a serious audio tool and a stylish daily accessory.

Independent Acoustic Chamber Concept

Inspired by Acoustune’s signature independent chamber architecture seen in its wired IEMs and HSX1001, HSX ONE physically separates the metal acoustic chamber from the wireless electronics module. The CNC aluminum chamber tightly houses the dynamic driver, while the wireless circuitry resides in the polycarbonate outer shell. This separation reduces electromagnetic interference and preserves acoustic purity, allowing HSX ONE to stand out among conventional TWS designs with cleaner, more precise sound.

Exclusive Third-Generation Myrinx Dynamic Driver

At the heart of HSX ONE is Acoustune’s proprietary third-generation Myrinx 10 mm dynamic driver, made from a medical-grade high-polymer biomaterial commonly used in artificial skin and surgical sutures. As a diaphragm material, Myrinx offers a rare combination of lightweight construction, high damping, and structural strength, achieving high-resolution sound, fast transient response, and wide dynamic range.

Because HSX ONE is more compact than the flagship HSX1001, Acoustune re-engineered the rear chamber volume and driver structure specifically for this model. The tuning pays special attention to low-frequency control and standing-wave suppression to complement the ANC system and deliver refined, layered bass performance. This dedicated design unleashes the full potential of the Myrinx diaphragm, producing a sound that is both detailed and richly textured.

Hybrid ANC – Enjoy Acoustune Sound Anywhere

As Acoustune’s first true wireless earphone with Active Noise Cancelling, HSX ONE reduces ambient noise by up to approximately –35 dB, creating an immersive listening environment in busy surroundings. A Transparency mode lets external sounds and voices in when needed, ensuring safe and comfortable use during commuting, office work, or outdoor activities. Whether you want to isolate yourself with music or stay aware of your environment, HSX ONE adapts with a simple mode switch.

Co-Developed Wireless Module & Smart App Control

The wireless module in HSX ONE is co-developed with ANIMA, a sister company specializing in true wireless earphone design. Using Bluetooth 5.4 and support for SBC, AAC, aptX, aptX Adaptive, and aptX Lossless, HSX ONE ensures high-quality wireless transmission and preserves more of your music’s original detail.

Through the dedicated ANIMA Studio smartphone app, users can adjust device settings, update firmware, change ANC modes, and configure notification sounds. The app also supports Advent Voice, allowing you to customize system prompt tones and languages for a more personal and intuitive user experience.

Everyday Convenience & Wireless Charging

The HSX ONE charging case supports wireless charging; simply place it on a compatible charging pad for effortless power. An included foldable storage case provides snug protection for the earphones and case when on the go. These thoughtful details make HSX ONE an excellent daily companion for music playback, voice calls, and noise isolation throughout your routine.

Made in Japan – Your Daily Audio Companion

HSX ONE carries forward Acoustune’s high standards for sound tuning and build quality while adding modern fashion elements and user-friendly features for everyday use. With its Made in Japan craftsmanship, third-generation Myrinx driver, and Hybrid ANC tuning, HSX ONE offers the brand’s characteristic clear, layered sound with richer, more dynamic low-end response that suits a wide variety of music genres. It is designed to bring genuine high-quality audio into real-life daily scenarios—your “everyday partner” for music and style.
