APACER Audio Steno AU581 MP3 player is not frills, lipstick-size audio player, vaguely resembling a network of Sony Walkman series, with its dual color translucent design. It comes with 2GB Flash memory, FM-radio with recording function, not a custom 7 preset equalizers (EQ) and plays MP3, WMA and WAV files.The design of the four main directions towards the pad, the center OLED display and double-click the equalizer and Recording at the front. The power button, headphone and a mini-USB port have been deployed along side.The interface is basic and straight-forward. Nevertheless, a slight lag each time the button is pressed becomes a bit annoying. We also omitted because of the lack of an option to renew.



Play stops when you switch on the menu, and can not resume when you return to the main menu. There is no Playlist function, which means the tracks are reproduced in a direct playback mode or folder. Despite the drag functions, transferring 161 MB of music took 5 minutes and 18 seconds - quite slow for USB 2.0 devices. The sound quality secondary. Preset equalizer helps in the normal mode effects the most. Earplugs were unable to deliver a set of troubled low-and high blunt.Our own headphones Sennheiser CX300 produced a more natural sound, but still lacked the deep bass and clear high and there is no audible distortion at maximum volume. FM radio (with no automatic scanning, though) worked fine and voice recording good enough for the accidental use. Estimated battery is 9 hours, but it lasted 7 hours during our listening session. The battery non-removable, so you can not just plug another.
