- C:04 Acoustic Chamber & M:04 Wired Module: Detachable CNC aluminum housing engineered for minimal resonance.
- Modular Wireless Compatibility: Fully interchangeable with Acoustune HSX1001 wireless modules (e.g., M:01).

C:04 Acoustic Chamber with Lithium-Magnesium Dome Driver
At the heart of the XHS1400 lies the C:04 acoustic chamber, engineered from lightweight, high-rigidity CNC-machined aluminum. Utilizing Acoustune's signature Myrinx dynamic driver technology integrated with a specialized lithium-magnesium alloy dome, this earphone delivers deep, tactile bass response alongside crisp, fast-transient mid-high frequencies. The acoustic tuning brings out micro-details and emotional nuances in every track with stunning musical clarity.
M:04 Wired Module & 4.4mm Balanced Connection
The separate M:04 wired module matches the acoustic chamber's precision aluminum construction and houses high-durability Pentaconn Ear connectors. Combined with the included ARC83 4.4mm 5-pole balanced cable, the XHS1400 instantly connects to high-resolution DAPs and USB DACs for clean signal transmission and enhanced soundstage separation.
Modular Design & Upgrade Path for HSX1001 Series
Acoustune’s hallmark fully detachable modular structure separates the driver-housing chamber from the connection module. The XHS1400 offers full cross-compatibility with the Acoustune HSX1001 series. Detach the C:04 chamber and pair it with the M:01 wireless module (from the HSX1001 Jin) to instantly convert your wired IEM into a high-fidelity true wireless earphone—making it both an outstanding standalone earphone and an ultimate upgrade accessory for existing Acoustune owners.
Durable, Flexible ARC83 OFC Balanced Cable
Designed for daily listening and long-term durability, the included ARC83 cable features high-purity Oxygen-Free Copper (OFC) wiring inside a soft, tangle-resistant jacket. The robust Pentaconn Ear connectors resist wear from repeated disconnections and seal against moisture and sweat. Cable length: approx. 1.2 meters.
