Sound quality: Monster's Blaster 3.0 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 a bit thin, metallic and somewhat hazy and grainy. Treble is extended but is somewhat smeared, sizzly and dry, and the upper treble prominent. Does a so-so job of recovering room ambience and is a bit congested. There is no significant difference between Bluetooth and Aux inputs. Provides a decent volume level in a large sized room.
