Sound quality: Ultimate Ears's Epicboom had acceptable overall sound quality - this model reproduces music and dialog reasonably well despite the obvious shortcomings in its sound. The bass has decent impact, is a bit subdued and boomy, and the deep bass is lacking. Midrange is fairly even, but is somewhat hazy, a bit grainy, and a touch plasticky. Treble is fairly extended, but is a bit smeared, sizzly and dry. Does a decent job of recovering room ambience, but sounds somewhat congested. Provides a decent volume level in medium sized room. The Outdoor Blast sound mode has a noticeable effect on the sound; the bass becomes a bit tubby and the midrange becomes more prominent.
