Sound quality: UE's Wonderboom had fair overall sound quality. Bass has so-so impact and mid bass is boomy and lower bass is lacking. Midrange is thin, gritty, somewhat congested, a bit echoey. Treble is prominent and smeared. Doesn't do a good job of recovering room ambience and is somewhat congested. The speaker is stereo but sounds like mono unless your really close to it. Provides a decent volume level in a medium sized room.
Ease of use: We found the UE Wonderboom 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 large high contrast (+/-) buttons and also has max volume audible indicator. Unlike most models in our ratings the device lacks a line-in input jack.
