What People Are Saying

Rated 2 out of 5 by from Great sound but buzzing noise on multiple inputs After a few days a buzzing started on multiple inputs.

Rated 4 out of 5 by from I purchased the SJ4y-s Sounds great but it interferes with tv WiFi. I use a wireless router for tv signal through my provider and when I turn on sound bar it causes my tv signal to pixelate and inter fears with signal

Rated 2 out of 5 by from Nice sound, but... I like the sound but frequently when I change channels it starts a high pitched hum and won't stop until I either keep switching channels or turn it off and back on. Not real convenient.

Rated 5 out of 5 by from Great Sound Purchased this to go with our LG tv. Sounds great and I can use the tv remote to control the sound. No need for 2 remotes. It sounds like a true surround sound system without all the speakers and wires around the room.

Rated 5 out of 5 by from Great purchase Bought lg sound bar to provide sound for lg Oled 55" tv thru Bluetooth connection sounds great and like that it all connects together. Was disappointed that front speakers sold separately but would recommend purchasing this lg sound bar

Rated 5 out of 5 by from Like going to the Movies Fantastic sound and feel. I love to just play the DTS title at the beginning of the 4K blurays, it's like sitting on top of the speakers in a movie theater. The air around the room literally vibrates when I crank up the volume. I have already turned on several friends and family to this great experience. If you love movies and the sounds in them, you'll love this soundbar.

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
