Sound quality: JBL's Partybox 110 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 a bit prominent and boomy. Midrange is fairly even but is somewhat grainy, a bit hazy, and a touch plasticky. Treble is fairly extended but is a bit smeared and a touch sizzly. Does a decent job of recovering room ambience. Sounds somewhat congested. The stereo separation of the speaker improves when the speaker is positioned horizontally. No significant difference between Bluetooth, aux and USB sound quality. Provides a decent volume level in a large sized room. When two units are used as a stereo pair the overall sound can be made louder, and depending on placement the sound stage can be made wider.
