"Sony have developed an impressive little speaker that should satisfy a lot of people, especially those who want some kick and bass to their music. With the ULT button engaged, these speakers deliver an impressive amount of bass and the volume level sounds very good also. I can imagine these speakers would sound super loud with them at 100%.

All in all this is now my go to portable speaker - versatile enough to perform well in all environments that I've tried, a great sound and all at an incredible price - Sony, you've pulled it out the hat yet again!
