Used Astell & Kern SE100. Very good condition, battery life is excellent. Used in rotation as part of a large digital audio player collection which I am now downsizing.
Sound signature is unlike other Astell & Kern digital audio players, it is very relaxed, making it the perfect partner for bright or forward sounding in ear monitors. Runs a custom version of Android, some apps are supported but must be side loaded, see AK website for more details. However, none of the Astell Kern players are as good as a smartphone for using apps. Can also be used as a DAC for PC/Laptop.
Comes boxed with original accessories, USB-C cable unused. Will also come with a case (used).
