HC3 Hi-Fi Quality USB Dual-DAC Cable, by Astell&Kern.

Successor to the sought after PEE51, the compact AK HC3 makes it easy to enjoy real, uncompromising high-fidelity sound on-the-go. The AK HC3 adopts dual ES9219MQ from ESS, highly regarded by audio fans across the globe for its ability to produce ultra-high quality audio with excellent control and low power consumption.

The AK HC3 adds high-quality microphone support to the company's signature hi-resolution sound to enable more entertainment and voice features - perfect for PC and laptop gaming, video conferencing as well as for watching movies or TV.

Connect directly to a Windows PC, Mac, smartphone or tablet with a USB-C port, without needing a separate conversion adapter, and enjoy high-quality sound. The AK HC3 uses power from the USB Bus of the connected playback device, so does not need to be charged or be connected to a separate external sound card, amplifier or DAC. The AK HC3 is also compatible with iOS devices using the included USB-C to Lightning adapter.

Unlike most DAC products, the AK HC3 incorporates a rear output design to minimise noise as much as possible. By processing the digital signal after it has travelled through the dual noise shielded cable, the resulting sound is far superior and virtually noise free.

AK HC3 is super light with a full aluminium housing, and weighs only 20g. The compact and lightweight body embodies the AK design philosophy, emphasising their fundamental ethos toward the music. The high-quality finish hides everything except for design factors such as the contours and the logo, preventing any visual distractions for a more immersive music experience
