Sound quality: Polaroid's P2 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 so-so impact and is somewhat subdued and doesn't go deep. Midrange is somewhat grainy and thin, a bit plasticky, and the upper midrange can sound somewhat strident with some program material. Treble is fairly extended but is sizzly and can sound harsh with some program material. Does a decent job of recovering room ambience in the mid-to-upper midrange but nowhere else, and is somewhat congested overall. When two units are used as a stereo pair the sound stage can be made wider depending on placement. Compared to the Bluetooth input the overall sound of the Aux input is similar but the upper midrange to lower treble is a bit less strident and harsh. Provides a decent volume level in a medium sized room.
