What people are saying

Rated 1 out of 5 by from Not worth the hassle Connecting stops working constantly and now it Doesn’t connect at all. It is definitely a hardware flaw and LG won’t fix it. I would stay away and I’m not going LG in the future.

Rated 5 out of 5 by from Excellent Sound bar with speakers This is probably the best sound bar, I have ever owned. I have a lot of LG products and this one is my favorite. I have all 3 positioned right in front of the tv and it works fantastic

Rated 5 out of 5 by from Works Great! I bought this for my husband 3 years ago. Easy set up. Sound is good still, no issues. I would recommend if your looking for speakers for a small size room (13x17).

I have an OLED65C7P TV and a LG SJ7-C soundbar. Is there any way to connect Headphones and the soundbar so that both will work at the same time?

Asked by: tsez
No, a headset and a soundbar cannot be used at the same time. We apologize for the inconvenience.

My SJ7-c speaker which is the non-primary speaker keeps disconnecting. I have to switch it to the off position for a minute and switch it back to sound bar mode for it to work and it stays on for 2-10 minutes before it disconnects again. Can you help?

The sound bar is connected to the tv and shows that it is connected and it is on the correct function. However sound doesn't come from the sound bar. I even paired it with my Bluetooth phone and it still wouldn't play. Ideas?

Does the surround button have any effect on the audio if you are in Sound Bar mode or does this only apply if you are using the 2nd speaker in Back mode? Does Cinema mode give you separation (stereo) between the 2 speakers in Sound Bar mode?

Asked by: CGinSD
In soundbar mode the Primary unit and Secondary unit play as FRONT L/ R (Left/Right) speaker like a sound bar. The surround sound button would give you the feeling of sound to the left and to the right but would not give you the rear sound. With cinema mode you can enjoy more immersive and cinematic surround sound. ^CP
