What customers say
The Astell & Kern AK HC2 earns high praise primarily for its exceptional sound quality, driven by the dual DAC and powerful 4.4mm balanced output. Users consistently report pristine clarity and a superior soundstage, noting its ability to drive demanding headphones effectively. The build quality is solid and compact, reflecting a premium design. While enthusiasts value this uncompromising hi-fi performance, the device is specialized.

Know before you buy
Yes. The AK HC2 includes a USB-C to Lightning adapter in the box, allowing you to connect it directly to older iPhones as well as USB-C equipped iPads and Android devices.
No, the AK HC2 is entirely bus-powered. It draws its power directly from your smartphone, tablet, or computer, so you never need to worry about charging it separately.
The AK HC2 features a 4.4mm balanced output only. To use standard 3.5mm headphones, you would need to use a 3.5mm to 4.4mm adapter, though you will not gain the benefits of a balanced connection.
The volume is primarily controlled by your connected device. However, Astell&Kern provides an optional Android app that offers more granular volume control for a more precise listening experience.
By using dual CS43198 DACs, the AK HC2 bypasses your device's internal audio components to provide significantly higher resolution, lower noise, and better channel separation. The 4Vrms output also provides much more power, which helps drive demanding headphones that a standard jack might struggle to power.
Yes, the AK HC2 is designed with a powerful 4Vrms output specifically to handle high-impedance headphones that require more voltage than a typical mobile device can provide.
