  • Rated 5 out of 5 stars

    Better than expected

    I bought the 2.1 soundbar with the insignia 55 qled and turned my little apartment into a theater. I love the night mode for after hours viewing so i don’t disturb my neighbors. Did not think that the small sub would rumble like it does and the soundbar is surprisingly clear.

    Perfect size

    For the sound of the sound bar, it’s an awesome and excellent choice. The subwoofer sounds really good. Would recommend this for anyone who has a small one bedroom apartment for the living room.
