The AK Astell Kern PEE51 USB-C Dual DAC Cable uses the design concept of “light and shadow” that is used in all Astell & Kern AK products.

The USB-C Dual DAC Cable design is based on a single centerline that boldly crosses from right to left. The faces were arranged by adjusting the angle ratio so that the sharp faces of the upper four faces meet at one point. It is designed so that each side is reflected according to the movement of light.

The Astell & Kern AK USB-C DUAL DAC CABLE has been designed as an extension of existing Astell&Kern DAP lines.

Smartphone manufacturers are removing headphone jacks from their products.
Without a headphone jack, how do you listen to music on your smartphone with the headphones and earphones you currently own?As streaming services begin to support high-quality, high-resolution audio, are wireless earphones and headphones able to provide the full audio playback experience?How can you enjoy high-quality music playback or games with dynamic and realistic sound on your computer without an expensive high-end sound card?
