Detailed Test Results

Sound quality: Ultimate Ears's Boom 4 had acceptable overall sound quality - this model reproduces music and dialog reasonably well despite the obvious shortcomings in its sound. Bass has good impact but is a bit boomy, and deep bass is lacking. Midrange is fairly even but is a somewhat hazy and grainy. Treble is fairly extended but is a bit subdued and sizzly. Does a so so good job of recovering room ambience, sounds somewhat congested and is lacking in detail. It can provide enough volume to be heard in a medium to large sized room.
