What People Are Saying

Rated 5 out of 5 by from Apartment Perfect I'm thoroughly enjoying the sound that I'm getting. I try to be considerate and not have the volume too loud and I'm still getting movie quality sound . Because my living room in small the sound is almost surround-like. I have a 44" LG HDTV I purchased one for my son for father's day and he loves it on his 55" LG HDTV

Rated 4 out of 5 by from Good Choice for Us We had a surround sound system with all the wires and needed to slim down so I decided on the SJ5Y-S because most reviews were good. We think it's a great product and after about 2 weeks we decided to get the rear speaker kit. We are really happy with this little system, so nice and compact with a huge sound. My husband has a hard time hearing and this system is great for him. Would buy it again; have already told my friends, who have whimpy little sound bars, to check into this one.

Rated 3 out of 5 by from I guess its all right Could have better instructions when setting up. Since so little info is provided I am unsure I actually have it set up for optimum performance. The online manual didn't help. Will have a friend who is a tech reset it and my new LG 65" TV, feel like LG could do a better job communicating instructions. Not everyone lives and breaths tech stuff.

Rated 5 out of 5 by from Great for the 86SJ9570 86" TV The sound bar extends the TV sound very well. Excellent addition.

Rated 5 out of 5 by from Great Features Very impressed - just when you forget you have it, you are startled by the sound coming from behind you! Love that it links directly to an LG TV and you only have to use one remote controller

Rated 4 out of 5 by from Great addition to my LG OLED Got this about 3 weeks ago. Very easy to set up and connect to my LG OLED tv set. I love that I can control both the TV and Soundbar with just the TV"s remote. I had experienced the sound drop outs that others have had but I updated the firmware and it seems to be a lot better now. The sound is really impressive. The addition of the subwoofer really fills the room with great bass without being overly boomy. Overall, I'm very happy with the purchase. Great build quality too. Does not look or feel cheap.

Rated 5 out of 5 by from Love this sound bar We bought this sound bar 3 months ago and we love it. It would take about 3-5 mins to setup and you are good to go. We have connected this sound bar with LG tv and it works very well and great sound. We also use Bluetooth extensively to play music or to watch the pictures from tablets or smart phone. I highly recommend this product

Hello .. I just purchased a lg 70" tv model uj6570. I want to know if I can hook up a Lg Bluetooth sound bar wirelessly and which model is compatible ? . Thanks!

Asked by: Big Meech
Hey idk why that “LG” rep that answered this questioned answered in that manner which is COMPLETLY INCORRECT. I apologize for there laziness and lack of product knowladge. To answer your question, it has to do with the TV you’ve purchased you would go into your TV settings into AUDIO. Then proceed to SOUND OUT if the TV has this option you will see SOUND SYNC... BLUETOOTH then proceed to place the sound bar int “ LG TV “ mode.

Using the optical connection, how do you get the tv remote to show the volume bar and mute on tv screen. The s.b. remote works fine, but doesnt show visual sound level on screen.
