The JBL listening is great, treble, mid, bass, everything is harmonious but the series load 2 is distorted and noise that strikes all.
The Bose's fine too but much too low, a sound a little muffled the JBL but very good nonetheless.
And finally the Sony that is very similar to the Bose bass less present, just right in fact, it's just that they are too present on the Bose but after that is a matter of taste :)
Note that with Sony we approach the sound of JBL by activating the option "Sound" on the Sony speaker that allows a sound less "choked" so I can listen to several music style, without Metal the Sound option, classic with Sound option etc ... is to discretion of each, but on some music I do not like having a sound too "crystalline" as the JBL which can sometimes be perceived as too aggressive ear, the Sound option leaves the choice to the user to enable or disable this report.
4 stars because autonomy is not great but it's still okay and she asser recharge quickly.
Otherwise it is Sony so very very good, is not cheap at all !! :)
