Harman Kardon GO + PLAY Speaker (Dogsthorpe)

This speaker comes complete with the power lead, and a working remote control.
Please note ….. There is no iPod included.
It has hardly been used but unfortunately when I came to use it this time, it appears to have a fault with playing music with heavy bass and gives distortion. It plays fine with music with normal base. So I am listing it for parts or not working.
Outwardly considering how old it is, it is in very good condition apart from two slight scratches next to the front facing right speaker , shown in the last photograph.
