Rated 1 out of 5 by from great idea but horrible execution I have never experienced buyer's remorse as badly as this purchase. It produces good sound, but only when it wants to. The left/secondary speaking is constantly cutting out. The subwoofer randomly cuts out every 20-30 seconds. Sometimes it makes this weird rumbling/rattling sound. We were watching a movie and the dialogue was so low we had to turn the volume up high and then the sound effects would be too loud. I really wanted to love this but I would give anything to be able to return it and get something better. [This review was collected as part of a promotion.]

Rated 5 out of 5 by from My new soundbar spoils me! I bought for my birthday....instantly spoils me. It was super easy to set up and is a sexy accessory to my living room. It sounds awesome with the bass and treble. I am extremely happy with it and the fact that it can be wireless, I can't wait to enjoy it as such. [This review was collected as part of a promotion.]

Rated 3 out of 5 by from It's Ok. The sound quality is good for a speaker it's size but Bluetooth is iffy and one speaker is experiencing a "popping noise" that I can't pinpoint. [This review was collected as part of a promotion.]

Rated 4 out of 5 by from Easy to set up This was easy to set up and I like the flexibility of splitting the speakers so that they are on either side of the TV. The sounds is good, better than just using the TV speaker. [This review was collected as part of a promotion.]

Rated 1 out of 5 by from Speakers randomly disconnect from each other The system is great in terms of a flexible setup, but the speakers disconnect from each other. The disconnects cause the sub and right speaker sound to go in and out. This seems to occur randomly. [This review was collected as part of a promotion.]

Rated 4 out of 5 by from Good design - great sound I bought this product as a gift. The sound quality is great. Really enjoy watching movies now with this sound bar. The reason why I'm giving this review "good" vs. "excellent" is due to the Bluetooth compatibility. Its great I can play my music on my computer through the sound bar; however, every time I turn on my wireless headphones, it turns off the sound on the TV. So if someone is watching a movie and then someone else wants to list to music from their computer with the wireless headset, the sound for the movie stops. I'm unable to find a solution to this problem. Other than that one little issue, I'm very pleased with the product. I really like how the speakers can be separated on each side of the TV, or take one in another room. Great feature. [This review was collected as part of a promotion.]
