Sound quality: Insignia's Portable Bluetooth Speaker (NS-CSPBTHOL16-BK) had fair overall sound quality. What little bass there is has little impact is subdued and deep bass is lacking. Midrange is grainy and somewhat hazy. Treble is somewhat subdued, smeared and sizzly, and upper treble is muted. Doesn't do a good job recovering room ambience, sounds congested and is lacking in detail; may sound compressed and slightly distorted with some content. Bluetooth and wired sound quality are similar. Provides a decent volume level in a small sized room.
Ease of use: We found the Insignia Portable Bluetooth Speaker ease of use to be good overall. Volume controls are low contrast, there is nothing to indicate that it is a volume control except + and - symbols. Bluetooth pairing is easy - the unit is always in pairing mode when not already paired, shows a pairing mode indicator. Indicates when pairing mode has occurred and never times out. The line input has priority over Bluetooth when plugged in with slight or no delay. Unambiguous. Aux input has low contrast labeling.
