I looked at the S1 for a while but figured it was too good to be true. I may need to revisit it. What's the navigation, volume changes, etc. like?
The handling is very simple, very similar to Zishan Z3.
It has 32 volume steps. Few for my taste.
It is not Gapless.
The reproduction is by folders.
It has equalizer.
It has no line output.
It has line input, it can be used as an amplifier.
It has Bluetooth.
5 buttons:
Left: Back, previous song
Right: Go ahead, next song
Up: Volume Up
Down: Volume Down
The central button performs three functions:
- Long press: turn on / off
- Middle press: return to the list of songs
- Click: play / pause
When turned on it returns to the exact point of the song where it was turned off
