What People Are Saying

Rated 1 out of 5 by from DO NOT BUY!!!! I've had this sound bar a little over a year and loved it, until my neighbors kid figured out he could connect to it via completely unsecured Bluetooth any time and blast racist rap music in the middle of the night to terrorize me. I contacted LG and they tell me there is no way to prevent anyone from connecting via Bluetooth. Basically anyone in range can connect and override your input selection, play anything they want, and crank the volume. If you live in a condo like I do and have an immature neighbor this is a huge issue and LG is completely unwilling to do anything about this blatant security flaw.

Rated 1 out of 5 by from Seriously, can't we get a recent software update? Sound is great, but all video and audio skip while in use. Found a software update, but no change. Then found a more recent update (with a slight file name change for the model), and still skips.

Rated 1 out of 5 by from Cuts off and on every15 minutes or half hour It sounds OK. Nothing to compare to a real old school stereo like stores used to sell. Now we are stuck with these half-baked sound bars. This one is not even half-baked. It cuts off about every 15 minutes. It goes off for a tiny moment, and then comes back on. So much fun when you are watching a nice relaxing movie. Life is Good really is the LG brand. Not.

Rated 3 out of 5 by from Sounds good when working My wife and I received this as a wddding gift. It sounds great, but the subwoofer cuts in/out every now and then. It isn’t all the time, but enough to be noticeable. I tried the software update and it didn’t fix the issue.

How can you advertise the SJ4Y system as being "Wireless Surround Sound Ready" when the only compatible wireless rear speakers have been discontinued? Very misleading...

Asked by: JakeDDS
At the time when the LG 2.1 ch High-Resolution Audio Sound Bar, Model # SK4Y was released, the LG 2.0 ch Sound Bar Wireless Rear Speaker Kit, Model # SPJ4-S which was specifically designed for compatibility with the Soundbar was also available. Regrettably, the Rear Speaker Kit has since been discontinued even though the Soundbar is still available...^IFV

Do I need to purchase a HDMI cable to use this?

Asked by: angola76
That will depend on what you are connecting the LG 2.1 ch High-Resolution Audio Sound Bar, Model # SJ4Y to. The Soundbar supports Bluetooth so it can be paired with a Bluetooth enabled device to stream audio wirelessly from the device to the Soundbar. If the device that you are connecting it to does not support Bluetooth but has an HDMI Output, you will need to purchase an HDMI cable to make the necessary connection to the HDMI Out on the Soundbar. This Soundbar also has an Optical Digital Audio Input that you can connect to a device that has an Optical Digital Audio Output on it. You can use the supplied Optical (Toslink) cable to make that connection...^IFV

I see the satellite speakers to go with this system are discontinued (SpJ4). Are there other compatible speakers that I can make as the rear speakers?

Asked by: jbdad
The LG 2.0 ch Sound Bar Wireless Rear Speaker Kit, Model # SPJ4-S was specifically designed for compatibility with the LG 2.1 ch High-Resolution Audio Sound Bar, Model # SJ4Y and Model # SJ5Y. Even though the speaker kit shows as being a discontinued product on our site, it may still be available from the retailers who sold the unit if they still have stock on it. You might also want to see if Amazon or eBay might still have it available. Our Authorized Parts Distributors should also have the rear speakers for the LG 4.1 ch Sound Bar Surround System with Wireless Surround Sound Speakers, Model # SJ4R that should work with Model # SJ4Y. You may also want to contact our Support Center at (800) 243-0000 to inquire if the LG 2.0 ch Sound Bar Wireless Rear Speaker Kit, Model # SPK8-S is compatible...^IFV

Running this through an optical cable. Every time the bar is on, the audio and video cuts out for brief moments. Tv is an LG 43UJ6200. When I turn the bar off, everything is fine. Will the firmware update solve this issue?
