As well as the player Astell & Kern other volume type 1 knob, AK Jr too but made more compact, without feeling brittle and easy to accidentally hit.
Like the current player, AK Jr Micro-USB standard uses extremely popular. The phone is available in Korea. The bottom has a layer of glass dorsal pattern aesthetic motifs increase for the machine.
AK Jr is equipped with capacitive touch screen 3.1 inches. User interface is well designed and comfortable. This player can not line out port or signal output port coaxial. Instead, to use the line out, AK Jr gives the user the choice of all sizes increase the volume level to become the line out.

Sound quality
AK Jr runs very smooth music files smoothly, from the DSD or lossless, without any hiccups or delays as seen in a number of audio products from China. The ability to drag the AK Jr is not high. With these in-ear headphones, including ones with large impedance, the machine no problem handling, including fullsize conventional headphones too. But if to pull smoothly the K701 headphones like the HD800 or AK Jr. is not an option. In my opinion, this music player combined with in-ear or earbud is the most reasonable, in line with the mobility of a compact player.
The first impressive thing about AK Jr is it creates the background sound is very clean. The noise in the background sounds absolutely no, the width of the soundstage well, with an open and wide. The location of the instrument is shown explicitly, creating the feeling of a space of high quality music. Sound is also very detailed expression, no feeling fuzzy, opaque.
I coupled with the Phonak AK Jr 232 to evaluate typically the most accurate way of AK Jr. The first thing worth mentioning is the AK Jr hear is that it creates a fuller bass range, not enough to make the Phonak headset headphones Beats but reflect a negative strip can say is “full” over. Add a little bit here and there, and there, in the bass sound buffer “A thoundsand Years” sweet and warm, yet contribute to creating space sad but beautiful music. But also with those who were familiar with the bass of the music player, the Walkman can also find AK Jr little bit lack of full-range bass volume as well as the sub bass. But AK Jr represents the tonal range of this trend and the full balance, no additions, no substances known like “fun”, was met bass phenomenon nor tail, slightly sticky with some of the same players other music.
High strips also very gentle and delicate but not too prominent. Guitar sound of legendary guitarist Slash in the “Do not Cry” up high enough, sharp enough. With a headset beautiful strip Phonak Treb Treb 232, the sound is even more beautiful and the guitar sound or when listening through AK Jr. Bright sounding bands that fit, these headphones a little bit light distribution where the hearing was. Granularity of the tonal range at a good level, not excessive influence for the musical part of the often very sensitive Treb strip. Phonak 232 is a headset with a very high degree of detail, which when coupled with AK Jr.
In aggregate, the AK Jr. is senior player cost is not too high, meet the criteria for a player is compact portability, ease of use and compositing and sound quality self natural, rustic. This is also the first step for people who love the sound foothold in the world’s high-end audio.
