Sound quality: Denon's Envaya DSB200 had only fair overall sound quality. Bass has good impact but is a bit pronounced, murky, boomy, constricted, and doesn't go deep. Midrange is muffled, congested, and gritty, and treble is extended but recessed, soft, and a bit smeared. The speaker doesn't do a good job recovering room ambience--a sense of acoustic space in which the recording was made--and the midrange sounds somewhat congested and lacks fine detail. There was no significant difference in sound quality whether a Bluetooth or wired connection was used. The speaker can provide a decent volume level in a small to medium-sized room.
Ease of use: This speaker system was super easy to use. Bluetooth pairing is very easy, whether it's done manually or via NFC. Controls are obvious, are well positioned, and have good contrast. This speaker doesn't come with a remote, which isn't an issue if it's located nearby or if it's being used with a mobile Bluetooth device that can act as the remote control, but it could be inconvenient in other situations.
