Sound quality: Polaroid's P3 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 decent impact but is a bit subdued and boomy, and deep bass is lacking. Midrange is somewhat grainy, a bit hazy, and the lower midrange is a bit subdued. Treble is fairly extended but is sizzly and harsh. Does a so-so job of recovering room ambience and is somewhat congested. When two units are used as a stereo pair the sound stage can be made wider depending on placement. There is no significant difference between Bluetooth and Aux inputs. Provides a decent volume level in a medium sized room.
