Query: Poor sound quality

Low expectations key to avoiding disappointement. At least in an appartment building where the neighbors employ a variety of electronic devices the sound quality was poor, the songs sounded like they were coming from a dusty sratched up record spinning on a turntable. Changing channels (there are four) didn't help. Oh, and there were some minor problems too: couldn't get the remote to work, one cable was missing from the package while another came with a duplicate, only two batteries were included instead of four. Had to return the product. Maybe someone else with more patience and better luck will be able to get satisfactory performance out of this thing.
