What people are saying

Rated 1 out of 5 by from Subwoofer not pairing Green light keeps blinking but it's not pairing with the soundbar. Seem like a common problem with this model and I guess LG is not gonna fix this. So i'll return this to costco. Or are you guys willing to fix this for your customers? Almost all of my appliances is LG. I'll make sure there wouldnt be more LG in my house. We have too many choices these days

Rated 1 out of 5 by from Subwoofer failed in 1 year Subwoofer does not turn on after 1 year of purchase

Rated 1 out of 5 by from Garbage Product The subwoofer stopped working 6 months after the warranty and I would have to pay to get it fixed. After reading the reviews it seems that it is a common problem. The speakers would also cut in and out. The sound was decent when it worked. Don’t waste your money on something that will not last.

I just purchased the SN7R and setup only to discover that it is not network-connectable. What is a comparable LG soundbar that is network capable and would mesh perfectly with my 2018 era 65" LG OLED? (can't remember the class)

I Got the LG SN7R last week and was ableto connect it with my LG 55CX.  However, I found the sound of the rear speakers to be not up to par with the rest of the system.  Is there a plan from LG to come up with an upgraded rear speakers w/higher rated amp?

Asked by: JunKay
We are sorry to read that the rear speakers for the LG SN7R 5.1.2 Channel High Res Audio Sound Bar with Dolby Atmos® and Bluetooth did not live up to your expectations. We currently do not have any information about if LG has any plans to come up with an upgraded rear speaker kit with a higher output rating. New products are generally showcased and announced at CES in Las Vegas which is held within the first week of January each year and will begin on Monday, January 11, and end on Thursday, January 14, 2021. The other option you have is that the Bluetooth Surround Ready feature for the LG CX 55 inch Class 4K Smart OLED TV w/ AI ThinQ® (54.6'' Diag), Model # OLED55CXPUA lets you connect up to two LG XBoom Speakers, for a true surround sound experience (Models: PK7/7W/5/5W, PL7/5, RL3, RM2, RN9/7/5, ON9/7/5), or you could purchase the LG SN11RG 7.1.4 Channel High Res Audio Sound Bar with Dolby Atmos®, Surround Speakers and Google Assistant Built-in...^IFV

I have the lg sn7r soundbar. What app on the iOS App Store is compatible with this?

Asked by: Michael mike
The only app in the Apple Store that we have is the LG AV Remote app that is a universal Wi-Fi remote control launcher that allows a user to control network-connectable devices released since 2012. If both a smartphone and LG device are connected to the same router, you can use your phone as a traditional remote control after a simple connection process. However, since the LG SN7R 5.1.2 Channel High Res Audio Sound Bar with Dolby Atmos® and Bluetooth is not a network-connectable device, this app will not work with the Soundbar and we do not have another app that is compatible with the Soundbar...^IFV
