Sound quality: The Denon Envaya DSB250BT has Good overall sound quality. Bass has good impact but is slightly prominent and boomy and deep bass is lacking. Midrange is fairly even, but is somewhat grainy and hazy. Treble is fairly extended but a bit subdued, smeared, and sizzly, and lacks treble air. Does a decent job of recovering room ambience. There was no significant difference between Bluetooth and wire connected sound quality. When combined with a second unit to form a stereo pair they provide wider stereo separation the overall score remains Good. Provides a decent volume level in a small to medium sized room.
Ease of use: We found the Denon Envaya DSB250BT ease of use to be Very Good overall. The volume controls are large but low contrast buttons marked (+/-) and the unit has a visual max volume indicator. Switching between Bluetooth and Line-in: The line-in audio plays, but is automatically overridden by connected Bluetooth audio playback, when Bluetooth audio is stopped line-in audio resumes. The Aux input is not marked. Bluetooth pairing requires a press of a button with a low contrast label 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.
