Sound quality: VAVA's Voom 21 had good overall sound quality. Bass has good impact but is a bit boomy and prominent and deep bass is lacking. Midrange is fairly even but is a somewhat hazy, a bit grainy, plasticky and congested. Treble is subdued and smeared. Does a so-so job of recovering room ambience; overall sound is somewhat hazy and lacks some detail. No significant difference between Bluetooth and wired sound quality except that wired sound quality is more hazy and congested. Provides a decent volume level in a medium sized room.
Ease of use: We found the VAVA Voom 21 ease of use to be very good overall. Bluetooth pairing was excellent as the device is always in pairing mode when not paired. The volume controls are high contrast (+/-) buttons and also has max and min volume audible indicator. Switching inputs involves plug unplug where the line input has priority over Bluetooth. Aux jack input label is low-contrast.
