Picked this unit up for use outdoors at the park, beach, backyard, country home. Great little unit with fantastic sound quality for something this small. Clean sound, no distortion at any sound level. Yes, it lacks some punch at lower end and maybe some highs on top, but that's to be expected with 3" drivers. Overall, it sounds great with any genre of music and I am very satisfied with the purchase.
It's loud enough and pretty nice... But when listening to rock music the background seems to over run the vocals and mid level sounds... It's just not as good as I would have expected. I wanted a clean crisp sound. This is definately not that. It's okay but not as good as I'd expect from a Sony product / price.
