Sound quality: LG's XBOOM XL7 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 somewhat prominent and tubby. Midrange is fairly even, but is somewhat hazy, and plasticky, a bit grainy, and depending on the program material can be somewhat overwhelmed by the bass. Treble is fairly extended but is somewhat smeared and sizzly and a bit dry. Does a decent job of recovering the actual room ambience from the recording but the tubby quality of the bass adds an artificial sense of room ambience, and the overall sound is somewhat congested. There was no significant difference between Bluetooth and USB sound quality. It provides a substantial volume level in a large sized room.
