Sound quality: Harman Kardon's Aura Studio 4 had acceptable overall sound quality - this model reproduces music and dialog reasonably well despite the obvious shortcomings in its sound. Bass has good impact and goes deep but is somewhat boomy. However, the bass dynamic range can vary from a bit subdued to somewhat prominent depending on content. Midrange is a bit nasal, plasticky, and grainy. Treble is fairly extended, but is a bit subdued, smeared and sizzly. It does a so-so job of recovering room ambience and sounds a touch congested. The speaker provides a decent volume level in a large sized room, but is best suited for a medium sized room.
Ease of use: This model was neither exceptional nor subpar in its ease of use; it was acceptable overall.
