What People Are Saying

Rated 5 out of 5 by from Great sound I bought this sound bar to go with my LG 49” 4K hdr tv. I am surprised by how good the sound is. The voices are clear and the subwoofer produces plenty of base. I think the app could use some more refinements and better directions but over all I am well pleased with this product.

Rated 4 out of 5 by from Miss the surround sound Although it is an exceptional sound bar with excellent clarity, I miss the feeling of being surrounded by the action.

Yes I have a TCL 55-inch Roku TV that is not Bluetooth capable and I want to know I have the arc system and I want to know what kind of Sound by you guys can offer me

Asked by: Bigron0615
Hi bigron0615. Thank you for your interest in our Home Audio products. Please pardon us, but we are not clear on your inquiry and would need some clarification. We are not clear on if you are saying that your TV has HDMI ARC functionality and that you need an audio system that also supports HDMI ARC functionality. We have a number of Home Audio devices that will have HDMI ARC functionality, like Shelf Stereo Systems, Sound Bars, and Home Theater Systems. You can view our lineup at^IFV

I would like to purchase a LG soundbar to sync wirelessly to my OLED65B6P TV.  I have talked to sales people at Best Buy that say I will experience a time delay between the sound and the picture.  Is this correct?  

Asked by: Ring24
I just paired this Soundbar with a brand new 2017 LG OLED TV. There was a few milliseconds delay between the audio and video but easily adjusted with the built-in audio-video sync of the television.

Just purchased the SJ8 soundbar. Can we add rear wireless speakers to this soundbar. If so will any brand work. If not which one will. Thank you. 

Asked by: Bobf5
Regrettably, The only Rear Wireless Speaker Kit available is the LG 2.0 ch Sound Bar Wireless Rear Speaker Kit, Model # SPJ4-S which is only compatible with the LG SJ4Y and SJ5Y Sound Bar Models. There isn't a Rear Wireless Speaker Kit that is compatible with the LG 4.1 ch High Resolution Audio Sound Bar, Model # 4.1 ch High Resolution Audio Sound Bar and another brand will not work with it. However, as a Music Flow unit, you can connect additional Music Flow speakers through your home network to it...^IFV
