What People Are Saying

Rated 4 out of 5 by from Great sound I purchased mine about two months ago as a gift for my new LG flatscreen. It was super easy to set up and the sink function worked well so there is . The sound is great especially for sporting events and movies . The only issue I have seen so far is that occasionally the wireless woofer sound will fluctuate and go in and out of contact with the main unit

Do I need to purchase an hdmi cord to install this model??

Asked by: JCampbell9
Hi JCampbell9. We are not clear on your inquiry about if an HDMI cable is required to install the LG 2.1 ch High Resolution Audio Sound Bar, Model # SJ4Y-S. The unit does not need installation. It has an HDMI IN, HMDI Our (ARC), an Optical Digital Audio Input and a 3.5 mm (Portable IN) port, all of which can be used to connect to devices that have compatible ports to connect to so you can play their audio through the Sound Bar. It also has Bluetooth Connectivity so it can be paired to a Bluetooth enabled device so you can stream audio from such a device wirelessly to the Sound Bar...^IFV
