Sound quality: Audioengine's B2 had good overall sound quality. Bass is recessed and has mediocre impact, lacking in detail and deep bass. Midrange is fairly even, but is somewhat hazy, soft and a bit grainy. Treble is extended but is subdued and sizzly. Doesn't do a good job of recovering room ambience and is a bit muffled and somewhat congested. No significant difference between Bluetooth and wired sound quality. Provides a decent volume level in a medium- to large-sized room.
Ease of use: We found the Audioengine B2 ease of use to be good overall. Connecting to Bluetooth is excellent, as the unit is always in pairing mode when not paired. Volume controls are not prominent, and are adjusted via a volume knob on the rear of the unit. Switching between Bluetooth and Aux sources is plug/unplug, with nothing ambiguous, but both will play at the same time, so you'll need to stop one in order to play the other.
