Sound quality: JBL's PartyBox On-The-Go had Good overall sound quality - this model reproduces music and dialog reasonably well despite the obvious shortcomings in its sound. Bass has good impact and goes fairly deep but is somewhat prominent and boomy. Midrange is even but is somewhat grainy and slightly hazy. Treble is fairly extended but a bit smeared and sizzly, and a touch prominent. Does a decent job of recovering room ambience; sounds somewhat congested. There is no significant difference between Bluetooth, Aux, and USB sound quality. Provides a decent volume level in a large sized room.
