The Starting Point of Music, AK Jr

Thin and Light

The AK Jr gives everyone the opportunity to comfortably listen to high resolution audio, anytime and anywhere. The AK Jr’s compact design delivers the highest sound quality while fitting comfortably in your pocket. It's 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. The full aluminum body and textured aluminum volume wheel allows smooth one-handed operation.

Increased output and lowered impedance

What are we talking about here? Simply put, the AK Jr supports many various types of earphones and headphones, a separate amplifier is unnecessary.


The AK Jr supports DSD, the digital audio format widely considered to be the next-generation in high resolution audio. DSD is converted to PCM allowing you to listen to a greater range of audio.


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.

Note: 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.

Full Touch Screen

The AK Jr features a 3.1" LCD touchscreen. The smartphone-like screen has full touch capabilities, offers a responsive interface and the large screen displays more information than previous models of our players.
