Know before you buy
The sterling silver construction of the ACT47 chamber is designed to improve high-frequency extension and clarity. By using a high-density metal, it minimizes unwanted resonance, allowing the beryllium dome to deliver more precise, detailed treble.
Yes, the HS2000MX MKIII uses the Pentaconn Ear connector system, which is highly reliable and easy to detach. Additionally, the included ARX500 cable features replaceable source-end plugs, allowing you to switch between different connection standards without needing a new cable.
The driver combines a medical-grade polymer biomaterial diaphragm with a Japanese-made beryllium dome. This hybrid approach balances the flexibility needed for natural, smooth mids with the rigidity required for fast, punchy bass and clean high-end transients.
No, the HS2000MX MKIII relies on passive noise isolation. By using the included SMP iFit® gels, you create a secure, comfortable seal in the ear canal that physically blocks out external ambient noise.
The modular construction allows you to swap out the acoustic chamber (ACT47) in the future. This means you can upgrade or customize the sound signature of your earphones as Acoustune releases new chamber designs without needing to purchase an entirely new set of drivers.
The package includes three different sets of ear tips: AEX70, AEX50, and AEX07. Each set offers a slightly different fit and acoustic seal, allowing you to experiment to find the best balance of comfort and sound isolation for your specific ear shape.
