Sound quality: B&W's T7 has good overall sound quality. Bass has decent impact but it's a bit prominent overall and lacking at the deep level. Midrange is fairly even but somewhat soft and "boxy." Treble is recessed and smeared. The unit does a mediocre job recovering room ambience. The sound is congested and lacks fine detail. There's no significant sound-quality difference between Bluetooth and wired connections. The speaker does provide a decent volume level in a medium-sized room.
Ease of use: We found the system's ease of use to be good overall. Bluetooth simply requires the push of a button. The problem is that button is not well marked. In fact, all controls have very low-contrast labeling, which makes identifying functions difficult. This unit lacks a remote, which isn't an issue if it's near at hand or paired with a mobile Bluetooth device that can serve in that role.
