When operating properly it has GREAT sound. However, the one I received has a defect which often causes voices and dialogue to fade and distort. It is not a constant issue, and when not present the soundbar is great. I took it to the samsung tech on the island, but he wasn't skilled enough to solve the issue, and I have since returned it to eScroll hoping for a repair or replacement, but so far there has been no update. Also, I cannot find reports of others with a similar issue online, so I must assume it is just a defect in the model I received. Hopefully it will be returned in perfect working order soon.
