Enquire about this product

Astell&Kern's 120 & 240 models are portable devices, but their relatively large size made it less convenient for those of us that like to travel swift and light.  

The AK Jr changes all that...

A compact design delivers the highest sound quality while fitting comfortably in your pocket.

It's a small concert in your pocket.

A new design story...
The AK Jr simplifies complex features of Hi-Fi audio to a smartphone-like experience. The raised screen provides secure grip and slims down the profile to just 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. Their 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. 

Forward looking formats like DSD to PCM supported
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. All the other formats are support as well including WAV, FLAC, WMA, OGG and more! 

It's also a 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.

Full Touch Screen Interface 
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.

Album covers that are in a 4:3 format on the AK100 are now displayed 1:1 aspect on the AK Jr’s larger screen.

More storage for the music you love
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 tracks. (Based on one, 4-minute song @ 24 bit/96 kHz, taking up 90MB).
