The Acoustune HS2000 Air is a high-end, modular In-Ear Monitor (IEM). Launched by the Japanese audio brand, it retains Acoustune's signature industrial aesthetic and mechanical performance while prioritizing lightweight comfort and accessible pricing.
The Acoustune HS2000 Air is a lightweight evolution of the acclaimed HS2000 series flagships. By introducing high-durability composite resin parts alongside a CNC aluminum alloy frame, Acoustune managed to cut down the overall weight of the earphone shells by approximately 50% compared to the HS2000MX MKIII. It utilizes Acoustune Capsule Technology (A.C.T.), allowing audiophiles to seamlessly swap modular acoustic internal chambers to alter sound signatures or implement future upgrades.
Ultra-Lightweight Hybrid Structure: Blends high-rigidity CNC aluminum with impact-resistant resin. The rounded resin design removes harsh angles, bringing the single-side body weight down to just 13g (excluding chambers/cable).
A.C.T. Modular Architecture: Features a 100% backwards-compatible chamber loading design. It accepts all existing or future ACT acoustic modules released for the HS2000 and HS3000 series.
ACT09 Chamber with 5th Gen Myrinx Driver: Comes standard with the newly formulated ACT09 aluminum acoustic chamber. This chamber houses the 5th generation Myrinx medical-grade synthetic dynamic driver, providing a highly elastic diaphragm that guarantees clean sub-bass extension and transparent high frequencies.
Premium Reference Cable: Equipped with the ARS53 8-core premium reference cable, meticulously woven using silver-plated OFC (Oxygen-Free Copper) and ultra-fine OFC conductors. It features highly conductive Pentaconn Ear connectors and a balanced 4.4mm termination plug.
Signature Aesthetic Paths: Revives two striking color palettes: Syosui (Sage Green) and Syokin (Elegant Gold).
Crafted in Japan: Engineered and manufactured under rigorous quality control standards in Japan.
