    More Details

    Comfortably listen to high resolution audio, anytime and anywhere.

    Although the Astell & Kern was a portable device, its relatively large size made it less convenient for some. The AK Jr’s compact design delivers the highest sound quality while fitting comfortably in your pocket.

    The AK Jr is like carrying a small concert in your pocket.

    The AK Jr most notably stands out because it features 24bit/192hKz high-resolution audio playback and supports a wide range of file formats, such as FLAC, ALAC, and DSD. It also packs a 3.1-inch touch screen and comes with 64GB of internal memory.

    If you want to expand that memory to hold more high-resolution audio files, you can go up to 128GB via microSD card. Other features include Bluetooth 4.0 support (for wirelessly streaming to speakers, etc.) and 1.95V RMS headphone output.

    Design Story
    • The AK Jr simplifies complex features of Hi-Fi audio to a smartphone-like experience.
    • The simplified design exemplifies the original concept of the AK Jr.
    • The raised screen provides secure grip and slims down the profile from 8.9mm to 6.9mm.
    • The full aluminum body and textured aluminum volume wheel allows smooth one-handed operation.
    Increased output and lowered impedance

    The AK Jr's output level of 1.95 VRMS represents a 14% increase over the AK100's 1.5 VRMS. Our engineers have reduced the output impedance to 2 Ohms for a significant gain in sound fidelity from the AK100’s 22 Ohms. As the AK Jr supports many various types of earphones and headphones, a separate amplifier is unnecessary.

    DSD to PCM

    The AK Jr supports DSD, the digital audio format widely considered to be the next-generation in high resolution audio. Listen to a greater range of audio through DSD.


    The AK Jr can also function as an external DAC (sound card) when connected to a PC or Mac via USB. When playing music stored on a computer, the AK Jr delivers the same high level of audio quality while eliminating the need for a built-in sound card.

    Full Touch Screen

    The AK Jr features a 3.1" LCD touchscreen that is about 1.4 times larger than the AK100’s LCD. The smartphone-like full touch capabilities offer responsive interface and the larger screen displays more information.
