Sound quality: JBL's Pulse 5 had fair overall sound quality - this model has sonic shortcomings that leave a lot to be desired when listening to music but don't rule it out for dialog. Bass has good impact, but is slightly boomy, and deep bass is lacking. The dynamic range sounds compressed and sometimes distorted on program material with strong bass and/or impulsive content. Midrange is somewhat grainy and raspy, a bit hazy, thin and nasal, and the upper midrange is somewhat strident. Treble is fairly extended, but is somewhat sizzly and smeared, a bit glassy, and the mid treble is a bit prominent and harsh. Does a so-so job of recovering room ambience, and sounds somewhat congested, and a bit constricted. This is a monophonic speaker. When two units are used as a stereo pair the sound stage can be made wider depending on placement. Provides a decent volume level in a small to medium sized room.
