Sound quality: JBL's Clip 3 had Fair overall sound quality. What little bass there is has little impact is subdued and deep bass is lacking. Midrange is grainy and somewhat nasal and thin. Treble lacks extension and is somewhat subdued, dry and smeared. Does a so-so job of recovering room ambience and is congested. The speaker is monophonic. The sound of the speaker "pumps" slightly (i.e. volume shifting/compression). There was no significant difference in sound quality between Bluetooth and Aux inputs. Provides a decent volume level in a small sized room and is best suited for near field listening, at its loudest volume levels, the sound becomes strained.
