The Bose Solo 5 is a better 2.0 soundbar than the Insignia NS-HSB318 2.0. It feels much better-built, has a more balanced, neutral sound profile, and supports Dolby Digital content over optical. However, the Insignia can get much louder, and compresses significantly less at max volume too. It also has a few sound enhancement features, like EQ presets and a bass boost mode, which the Bose lacks.
