This is not my first Bose unit, I also have headphones and Bose speakers small and with this speaker I find the sound that characterizes the brand. Clear sound that pulls in more serious than in the treble. The Plus, its small size so a light weight enough to be able to carry. His - the lack of acute and it reads (on the base surface) that new generations of iPod. However it is equipped with a jack system back to fix it but it's a shame. Anyway, this is a very good alternative between the mobile station and stereo.
