What People Are Saying

Rated 1 out of 5 by from Junk I bought it on 11/6/18. Sounded great. By 11/27/18 the woofer was constantly connecting and unconnecting. Like every minute or so. Tried all the trouble shooting solutions. Nothing worked. Never buying LG again.

Rated 4 out of 5 by from Nice Sound Added this to my 55” LG because of the wireless sub. Price point was excellent from Fry’s and delivery was fast. Sound quality is good and now there is bass that rocks movies at medium volume. No manual with this sound bar/sub just a quick start paper. It was not a quick start, plug and play installation even when it was added to an LG widescreen. Once you stumble through the setup it works.

Rated 4 out of 5 by from It's good but could be better Overall the soundbar is good but it could be better. HDMI ARC doesn't work when watching cable unless I switch the HDMI cable everytime I turn the soundbar back on but HDMI ARC automatically turns on when watching Netflix or some other source. Having an option to turn it on manually would make things so much easier.

Rated 3 out of 5 by from Audio out of sync with video The audio is out of sync with the video. The audio is about 1/2 second late as seen with a person's lips speaking. There's no way to adjust for this problem.

Rated 5 out of 5 by from Great Sound!! I bought this about a month ago and for the price it has very good sound. I like the extra bass feature and the sleekness of the sound bar.

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
