The product I really like, sound quality is very good, the beeps volume is irregular; sometimes it is noisy, but mostly quiet and therefore not disturbing. Unfortunately targeted not adjustable. Battery life is good. But the battery discharges relatively quickly if unused. Full shop, leave a week, then you have to charge it again. What person does not bother me, since I use it as well as every day. What I found to be disturbing, it is that there is no way to switch between the lists of songs is. It is only possible from song to song forward / reverse switch and take a break, but not between the directories. Songs are played not in the alphabetical order, but in the physical (such as recorded on the medium). It is also not possible to adjust the order or so. It is possible to go by means of a SDCard up to 32GB, but it's not really useful. But as I said for me this is enough, because I always grab the songs on it, I just want to hear. The administration is carried out at me on the computer, this is just a "straight forward" playback device. Especially useful I find the possibility to use the device as a stink normal passive headset using an audio cable. But not even need to be recharged the battery; it's great. The device I use only one in-door, from and also listen to the radio, is OK
