Sound quality: Kicker's Bullfrog BF100 had Good overall sound quality. Bass has good impact but is a bit subdued and lacks deep bass. Midrange is fairly even but is a bit hazy, and somewhatgrainy. Treble is somewhat prominent, smeared and sizzly and upper treble is muted. Doesn't do a good job of recovering room ambience and is somewhat congested. No significant difference between Bluetooth and wired sound quality. Provides a decent volume level in a small to medium sized room.
Ease of use: We found the Kicker Bullfrog BF100 ease of use to be very good overall. The Bullfrog connecting to Bluetooth is easy. Bluetooth pairing requires a press of the low contrast button which is also the source selection button 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, LED light flashes as well as when pairing has actually occurred. Volume controls are on the side of the unit but nothing to indicate that it is a volume control except + and - symbols which are low contrast, no index markings but has a visual indicator when you reach the max and min settings. Works with line in and Bluetooth inputs. Source selector is labeled only for Bluetooth pairing and is multi-function button that is low contrast that is not ambiguous and provides a persistant indicator of the selected source.
