    LG - SJ7 Sound Bar Flex 4.1 Channel Speaker System with Wireless Subwoofer and Bluetooth Streaming - Black-Front_Standard

    • Model: SJ7
    • SKU: 5807206

    love it...Love it!...This is a Simplink compatible device which means you can control the volume through the TV remote (if you have a compatible LG TV) 2 you can separate the two speakers and use the second as a surround sound rear speaker because the second speaker is connected to the first speaker using bluetooth....In conclusion I Think the unit is ok, great for smaller rooms maybe not big living rooms if you are looking for a full surround sound with rear speaker as I think the rear needs to be louder (not loud enough with it turned all the way up) like I said I would recommend this to friends and family who have smaller rooms.

    LG’s SJ7 Sound Bar Flex offers endless entertainment from a versatile dual-speaker design: The two main speakers can be placed in front of the TV, or to the left/right vertically or in front of and behind the listener for an even more cinematic experience. Both speakers are Bluetooth, and the right unit has a built-in battery, so it can work independently just about anywhere.
