The buttons are barely "engraved" or "molded" into the top, making it very difficult to see any markings. When an MP3 player is connected directly via an optional cable, a beep will sound each time you press any button. If that's not annoying enough, when using a TF card, you can't increase or decrease the volume. There are definitely better speakers than this one.
