Sound quality: Klipsch's The One II had Good overall sound quality - this model reproduces music and dialog reasonably well despite the obvious shortcomings in its sound. Bass has good impact and goes fairly deep but is a touch prominent and a bit boomy. Midrange is fairly even but is somewhat grainy, a bit hazy, and a touch etched. Treble is extended but is somewhat prominent and sizzly. Does a decent job of recovering room ambience, but sounds somewhat congested overall. There is no significant difference between Bluetooth and Aux inputs. Provides a decent volume level in a medium sized room. However, it sounds strained at higher volume levels.
Ease of use: We found the Klipsch The One II ease of use to be Good overall. Bluetooth: Unit requires a long press of an unmarked multifunction button (source knob), shows a pairing mode indicator and indicates when pairing has occurred. Volume control knob is in a prominent place, has a speaker symbol label which has good contrast, no index markings but has visual indication of when you reach the max settings. Works with Bluetooth and line-in. Switching between Bluetooth and Aux inputs requires the turn of a multifunction selection knob and has clear indicators of the selected inputs using good contrast labeling.
