The sound quality on most TVs these days is poor. But you don't know how poor until you add an separate audio system. I have a small 37" TV in a relatively small (20'x20') room; this low cost sound bar, vastly improved the quality of sound. As my hearing decreases with age, an external sound system becomes more and more important. This fit the bill for me, I can hear more dialogue on TV, Blutooth improves the audio quality of my iTunes, and the cost is reasonable.
