Perfect little device. Sound quality very good and bluetooth working nice. I recommend for buying.
Very fine audio board. It plays FLAC(!) and WMA too. Signaling LED Fast flashing - audio playback mode from storage media (USB or TF / microSD) Slow blinking - wireless reception mode (Bluetooth or FM radio) Steady light - classic audio input playback mode Switching the modes The operating modes are switched by successively long pressing of the middle button "Play / pause". The mode changes cyclically as follows: USB → TF / microSD → BT → FM radio → audio input →. The currently selected mode is indicated by a signaling LED. The default mode when no storage device is present is Bluetooth (BT) mode. If it is device (eg TF / microSD card or USB) is present, playback starts from it. The player after turning off "remembers" the tuned FM station, the selected FM station, the file being played and the volume.
