What People Are Saying

Rated 1 out of 5 by from Sound Bar does not work after 18 months We purchased this sound bar system in February 2014. We opted for LG based on positive reviews and with the thought that it would be most compatible with our LG smart TV. This past week, after only 18 months of use, the sound bar no longer turns on. We have tried multiple outlets and cannot power up the sound bar. The sound bar was plugged into the same surge protector power strip that powers the rest of our electronics and they are all fully functional. We are very disappointed with the quality of this product and will not purchase another LG.

Rated 4 out of 5 by from great sound at a great price This product gives great sound for a great price. As a movie watcher sound is everything and this sound bar delivers. Many options for sound and connections and it fits just right with it's size for most flat screen TV's.

Rated 2 out of 5 by from Subwoofer Doesn't Connect to Sound Bar Bought this sound bar system. The bluetooth subwoofer worked great and was very convenient, with great sound quality; however, I went on deployment for a few months, 3 to be exact, only to come back and find out that the subwoofer was no longer paired with the sound bar. I know, "First World Problems," but if it was free I wouldn't be complaining, However, I did pay some good money for this.

Rated 5 out of 5 by from Big sound in a little package. This soundbar is perfect for my 900 sf apartment. It fills all three rooms with full sound without disturbing my neighbors, although I certainly could.

How do I pair the two

Asked by: Tommyboy24
The instructions for pairing the Subwoofer and the main unit on the LG Sound Bar Audio System with Bluetooth Connectivity, Model # NB3520A can be found on page 11 of the owner's manual for this unit. You can download a PDF file of the owner's manual and print it out from []. The first time you turn on the main unit and the Subwoofer, they will automatically pair. 1. Press and hold □ on the unit and MUTE on the remote control simultaneously. - “REMATE” appears on the display window. 2. Press PAIRING on back of the woofer. - The Yellow LED will flicker. 3. Turn the unit off and the on. - If you see the yellow LED, it’ s successful. 4. If you don’t see the yellow LED, try again Step 1 - Step 3....^IFV

Bluetooth stopped working

Asked by: katie14
If the Bluetooth on your LG Sound Bar Audio System with Bluetooth Connectivity, Model # NB3530A stopped working, it may be due to one or two things. Either your unit lost connection and needs to be paired again with the device that you are streaming the audio from or that the device you're streaming from suffered interference and lost its signal. Either way, you can try to troubleshoot the problem. Try to see if the Sound Bar can receive audio from another Bluetooth device, or see if your device can stream to another Bluetooth device. It may just be that you need to pair the units again which you should try before trying anything else...^IFV

Bluetooth stops working eventually?

The soundbar's Bluetooth function no longer works. It was working perfectly until today. I searched the Q & A on here and apparently a few others have had the exact same problem as me: When we switch to the BT function mode, the display shows "BT READY", only "BT." This seems to be a critical problem with this model. The speaker becomes basically useless for me if the Bluetooth doesn't work. I wrote a favorable review about this item on because of the great performance/cost ratio - 300W speakers! But I might have to change this now...I have had these soundbar for less than a year.
Asked by: Raiden
Mine developed the same problem after a couple of months. Call customer service, They had me return mine for service and had it back to me in less than a week.

Why would sound stop coming from Subwoofer?

Asked by: DeDee
I have the same issue. I made sure the sub was paired to the bar, I get sound from the bar, green light is solid on the sub... but no sound. LG should offer replacement subs. Now I have a nice soundbar without any lows. Pretty much useless.

"LG TV" input explained

I noticed along with two optical inputs, the soundbar has one that says "LG TV." What is the purpose of this?
Asked by: theotherjustin
The LG TV input is for people who own an LG Television set. If this applies to you, check your instruction manual.

Can I add additional speakers to the system

My basement is huge. I would like to add speakers so the sound is great all through the area. Can I add speakers to the NB3530A system?
Asked by: palivoda
I believe you would need a receiver with separate speakers and interface directly with the TV. I don't think you can add to the sound bar. Check with LG.
