Sounds very nice, the highs aren't as good as most Panasonics, but it's got lots of bass for a 1-piece, and it's probably the 4th most powerful 1-piece after the M90, C100 and RX5350. But it doesn't have a Wide setting, and I got tired of the way it needed constant adjusting of the bass knob and DSL button to prevent the passive radiator from buzzing. You basically have to leave DSL off unless you're listening to something mild like classical or classic rock.
