    Much better than TV speakers
    Sounds great compared to the internal speakers in my Samsung TV. I wish the sub-woofer was adjustable but it has decent sound.

    Certainly not a surround sound replacement but very good for the price.

    Excellent sound quality, space saver, sleek. Very pleased!
    Very excellent sound quality for such a small device. There is a noticeable difference between having the subwoofer on or off. Can be a little tricky in the setup, and I sometimes have to restart it to properly switch from Bluetooth to digital audio, but it works very well. I am very pleased with this purchase and promptness of delivery.
