The Starting Point of Music, AK Jr

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.

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 converts 2.8 MHz DSD files to PCM.

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.

- The AK Jr's EQ settings are disabled when used as a USB DAC. The USB DAC feature also supports UAC 1.0 (USB Audio Class 1.0 / 24-bit, 96 kHz) audio output.
