At this price do not expect the ultimate functionality, but actually not bad: CD player, CD-ROM (not DVD), USB, SD card, radio, compact, infrared remote control, standard equalizer, Sound power sufficient for moderate piece (20m square). RCA auxiliary input (a red jack and one white) output jack. Function shuffle, repeat, intro. Navigation through the media usb / sd card is minimized (moving every 1 or 10 pieces), no viewing of files or song titles. The backlight (blue) is too intense. But all this does not prevent to listen to music properly. My one big problem with this micro channel is produced by the sizzling food and which increases as the chain is on AC power. So I never left idle. To listen to the quiet songs (jazz, classical ...) this "buzz" becomes very frustrating. But I guess for this compactness and price, it is difficult to have a power supply that does not heat that is does not produce interference. In short, set on a small shelf, I occasionally used to listen to some CDs and especially my MP3 shuffle since my USB key all from my desk via the remote and I unplugged the sector at the end.
