Sound quality: LG's XBOOM 360 had middling/satisfactory overall sound quality - this model reproduces music and dialog reasonably well despite the obvious shortcomings in its sound. With the LG Xboom app EQ setting set for the most even tonal balance, the bass has good impact, and goes fairly deep, but is a bit prominent and boomy. Midrange is fairly even, but is somewhat hazy and grainy, and a bit plasticky. Treble is fairly extended but is somewhat sizzly and smeared. Does a decent job recovering room ambience, sounds somewhat congested. The speaker is monophonic. The various user EQ modes make an obvious difference in the sound. No significant difference between Bluetooth and Aux sound quality. Provides a decent volume level in a medium to large sized room.
