Sound quality: Audio Pro's BT5 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 bit prominent and boomy. Midrange is fairly even but is somewhat hazy and a bit grainy. Treble is fairly extended but is a bit subdued, smeared, and sizzly. Does a decent job of recovering room ambience and is somewhat congested. The speaker is monophonic. No significant difference between Bluetooth and Aux inputs. Provides a decent volume level in a medium sized room.
Ease of use: We found the Audio Pro BT5 ease of use to be Very Good overall. Bluetooth pairing requires a press of a high contrast labeled pairing button on unit and then the selection of unit from Bluetooth selection list on source device; unit provides an obvious indication that the unit is in pairing mode as well as when pairing has actually occurred. The volume controls are well labeled +/- buttons with a visual indicator for max volume, and controls Aux input. Clearly labeled buttons for each source with labeled LED indicators that persistently indicate which source has been selected.
