Taking your music with you doesn’t have to mean substandard audio quality. Why not hear the true craftsmanship of PSY’s recordings with the Astell&Kern AK100, an ultra high-end portable audio system that’s capable of studio Mastering Quality Sound support and playback. It features 32GB of storage, a very robust 16-hour battery life, and a 2.4-inch touchscreen. Throw any type of file at it and it’s getting played: MP3, Ogg, FLAC, WAV, WMA, APE–whatever.
