Learn more about 4K Pass-Through


Why 4K pass-through matters for entertainment?

Lossless audio requires transmission over HDMI cables, as the data size is too much for an optical cable to handle. This is why important to plug your source into the Sound Bar.


Wireless Subwoofer, superb bass without wires

Rated 4 out of 5 by from Turns on randomly I purchased an LG TV bundled with this sound bar. At first everything was great but then my TV started to fail and I got it switched to a Sony. The soundbar and the TV were connected through an optical cable, but the soundbar started to turn randomly on by itself, with the TV off and any input from the remote (note the this only happens with the Sony TV, it didn't happen before with the LG). I read some reviews on different websites that the Sony TVs send a signal through the optical cable even though they are turned off, and that was making the soundbar to turn on. It made sense because every time the bar turned on it was on the optical function. So, what I did to try solve this problem was to connect them through HDMI/ARC instead of the optical cable, but the soundbar still turns on randomly. I don't know if this is a soundbar problem, a tv problem, or if it is just bad communication between two divices from different brands. Anyway this shouldn't happen. This is specially annoying when I connect my phone or my tablet via bluetooth to listen to music because it randomly switches to the optical function instead of the bluetooth and my music stops playing and I have to reconnect them again, over and over. Aside from this problem, the sound quality of the bar is amazing and super loud. Ive had my neighbors come to complain about me being so loud, but I just can help it because as I turn the bar on, the sound just asks to go louder.

Rated 5 out of 5 by from Great integration with LG TVs, even old ones! I bought when we upgraded our family room TV and set our old LG LH90 up for the kids in the basement. I didn't want to install a full surround sound system, so I chose a soundbar. I thought an LG sound bar would be the best option, but had no idea how nicely integrated the SJ9 soundbar would be with an old LG TV. The TV automatically detected the soundbar connected to the optical audio port, and the TV remote automatically controls the soundbar volume! It took all of 60 seconds to set this up and be amazed. Because it has bluetooth, the kids can pair their phones and stream any music they please. It even shows the music source like Spotify on the front panel. Lastly, the sound is great. I have not listened to native Dolby Atmos content yet, but overall, the sound is full and enveloping, and the audio rage is wide and not muddied. Beware the Bass Boost - it can get LOUD! So, its a home run as far as I'm concerned. [This review was collected as part of a promotion.]

Rated 3 out of 5 by from Dumb design Ok sound but the speaker bar blocks the IR signal from the remote to the LG OLED TV. I had to install an IR Blaster to work around the problem.

Rated 1 out of 5 by from Constant "Not Supported" Messages When it works it's amazing, however no matter what I'm watching (xbox one x, tivo, anything via HDMI), it will occasionally slip out of 5.1 and grind to a halt while displaying NOT SUPPORTED and then snapping back. It happens every 5-50 minutes, but when it does it totally takes you out of whatever you're watching or playing. On top of that, when you first turn everything on there's no audio. Video passes through fine but not video. You either have to turn everything off again or log into the Soundbar with the app and turn DRC off and on a few times until the audio restores (I keep it off by default). Super disappointing, I wish I had never purchased it. [This review was collected as part of a promotion.]

Rated 2 out of 5 by from Audio Sync How this soundbox interacts with the OLED television is lacking good user information. Sound is not that unusual and not sure what the big deal is about the Dolby Atmos Sound System as it does sound any difference. [This review was collected as part of a promotion.]

Rated 5 out of 5 by from Worth the cost I bought this several months ago to pair with my 75" 4K Smart TV and I couldn't be more impressed. Connected by HDMI (ARC), the sound is crisp and with the wireless subwoofer...movies and music sound great! [This review was collected as part of a promotion.]
