    The Starting Point of Music

    Little brother to the famous AK series portable high resolution audio players, the AK Jr Hi–Res Music Player puts FLAC audio in the palm of your hand. More compact than its big brothers, the 64GB AK Jr. doesn’t skimp when it comes to your FLAC (Free Lossless Audio Coded) and ALAC (Apple Lossless Audio Codec) files. Like carrying a concert in your pocket, the AK Jr. is thin, light, and simplifies complex Hi–Fi audio features into a smartphone–like experience with a raised screen for a more secure grip, a full aluminum body with textured volume wheel, and increased output with lowered impedance. A 3.1” LCD touchscreen enables smartphone–like touch capabilities and responsive interface for an improved user experience including the appearance of album covers, now displayed with 1:1 aspect ratio. The AK Jr. supports DSD (Direct–Stream Digital) files with pulse–density modulation encoding and functions as an external DAC (Digital to Analog Converter) when connected to a PC or Mac USB port, bypassing your computer’s internal soundcard to deliver the same high–quality audio you enjoy. Carry even more music with the additional 64GB microSD memory card for a grand total of 128GB of storage capacity, holding approximately 1,250 hi–res audio files.

    Thin and Light

    The AK Jr project gives everyone the opportunity to 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.

    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.

    USB DAC

    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.

    64GB Plus 64GB microSD

    The AK Jr features 64GB of memory to store more music than ever before. Supporting microSD cards up to 64 GB, the AK Jr is capable of offering a whopping total storage capacity of 128 GB. The combined 128GB of internal memory and external microSD card capacity is capable of holding more than 1,250 high resolution audio.
