Lightweight and compact. There is a clothespin, it clings to clothes, pockets, a collar without any problems, you can even fasten it on shorts, it will not interfere at all.
The declared time of the battery holds, I deliberately did not notice it, but when playing mp3 320kb / s in half with m4a (variable bitrate), I worked overnight (6 hours), then during the day (9 hours) and it was enough to drive for a couple of days (on the way to work and home), the only thing is that the charge divisions do not quite evenly disappear.
Plays most of the required formats, mp3, m4a, wav, wma, flac, ape, ogg.
There is a radio recording.
There are signs of the beginnings of a real player: the ability to open a list of files by category (artist, album, genre), open all files in one list, or open by folder. You can open a general list of all files that are and turn on the "random" mode to randomly play everything that is.
Remembers the playback position after the exit, as well as when viewing folders, automatically jumps to the last place visited last time, which simplifies the search.
Sound . Well, the usual sound, a simple line output. Sounds good with normal headphones. There is no noise, no hiss, no distortion, the volume is adjusted quite smoothly, without a step between 0 and 1, as it sometimes happens.
