High Fidelity
The Astell&Kern AK70 is the ultimate portable high-fidelity audio system capable of lossless audio playback. Feel the phenomenal realism of high-definition lossless music through 24bit/192kHz sound processing that cannot be heard through a standard CD.

Wireless Capability
The AK70 comes equipped with the AK Connect feature that can be connected with network-ready Astell & Kern devices. It is also appointed with wireless networking DLNA, which makes it easy to work with NAS/PC on the same network and through an AK Connect app supporting. AK70 also has Bluetooth connectivity for further wireless playback options.

Complete Experience
The AK70 is designed with an oblique angle on one side of the body so that it can fit the contour of the user's thumb, the finger used most frequently when controlling the screen with one hand. The volume wheel is designed to be protruding slightly from a concave surface so that you can control volume with a simple motion of sliding your finger up and down.

AK CD Ripper
The AK70 can allow users to rip CDs with ease by linking with the AK CD-RIPPER. By inheriting from the AK500N, it supports the CD track error correction feature and the meta data (ID3TAG) auto input feature using Gracenote's database without any change.
