With the Astell & Kern JR, you can listen to high-resolution audio anytime, anywhere. Its top-of-the-line hardware, such as the Wolfson WM8740 converter, delivers the highest sound quality while its compact design makes it easy to fit comfortably in your pocket. Because Astell & Kern's engineers have reduced JR's output impedance to only 2 Ohms, its sound fidelity is now flawless. It's like carrying a small concert in your pocket.
Astell & Kern JR comes with 64 gigabytes of internal memory which can be enhanced by a micro SD card of up to 64GB. With a possible overall capacity of 128 gigabytes, the JR can store around 1,250 songs in top audio quality. The player can also function as an external sound card when connected to a PC or Mac via USB.
The JR's aluminium body with a textured surface protects the player without adding excess weight. Its slim profile and great ergonomics enable easy one-handed operation. The touch screen provides a very intuitive way to control the player and displays all the relevant information on playback and settings.
