LG’s SJ7 Sound Bar Flex offers endless entertainment from a versatile dual-speaker design: The two main speakers can be placed in front of the TV, or to the left/right vertically or in front of and behind the listener for an even more cinematic experience. Both speakers are Bluetooth, and the right unit has a built-in battery, so it can work independently just about anywhere.

4.1-channel speaker system: More channels ensure better sound separation for an all-round experience.
Wireless Subwoofer: With 12.6" subwoofer to deliver a movie theater experience in your own home.
Rear Surround Sound: This sound bar is actually two separate speakers, and when configured in rear speaker mode, one can be placed behind the listener to provide real front-and-back surround audio.
Adaptive Sound Control: For maximum enjoyment of various types of programming (movies, sports, games, etc.), LG's Adaptive Sound Control can automatically detect what’s playing and then enhance the clarity and impact of the audio.
Flexible Design - Home Theater Versatility: Dual-speaker design of the LG Sound Bar Flex enables the system to be configured in a variety of ways. However you like to enjoy movies and music, this audio package delivers.
Portable Bluetooth: For even greater versatility, one of the speakers in this LG sound system is equipped with a built-in rechargeable battery, allowing it to be placed and enjoyed just about anywhere.
Inputs: HDMI and Optical inputs.
Bluetooth portable provides more ways to connect with the music you love: One of the speakers in this LG sound system is Bluetooth-enabled with its own built-in rechargeable battery, allowing it to be placed and enjoyed anywhere.
Vertical Positioning: The two independent speaker units can be stood vertically on either side of the TV, with stabilizing speaker pads. Audiophiles prefer such separation of stereo channels, which allows optimal dispersion of the soundwaves.

Whats Included

LG SJ7 Sound Bar Flex 4.1 Channel Speaker System with Wireless Subwoofer and Bluetooth Streaming

Q: Is this system something that would work for a person that is hard of hearing....put one in front of TV and one on a table by the couch?

A: Keep in mind the sounds coming out of each speaker can be different depending on the surround sound settings of the program and the speakers themselves. And you can't make it a front/rear setup because then most of the voices would mainly be heard by TV speaker. So bottom line, it would work, but it may not be ideal with "what" they hear vs what's heard from the other speaker. I recommend getting some RF headphones in addition to an external speaker. Most people can listen to the sound bar while a person that has a hard time hearing can use headphones and increase the volume without affecting others. My father-in-law currently has to use this setup so he doesn't blast everyone out of the room using the sound bar. A 3.5mm audio splitter is required for that kind of setup though.

Q: Can the LED display on speaker be turned off?

A: It can't be turned completely off; however, it is brighter after a key touch... then 15 seconds later, it dims automatically until a key is pressed again. You can always put electrical tape over that area if needed.

Q: Sub keeps cutting out no matter how far away it is. I've had it sitting 12 inches from the actual sound bar for the past 3 weeks and sub still cuts out. Unfortunately I didn't buy the best buy warranty but it is still within the 1 year?. Contact me lg

A: its a junk system they knew it was junk and sold it for cheap about two years ago, there is a software update on LGs website but it don't help much buy a different system bud that's the real answer

Q: Can i use the sj7 as rears for the sj9?

A: undefined

A: undefined

Q: My lg sj(8c) speakers turn up and down by themselves without warning, how do i fix this

A: undefined

Q: I have a 2013 60 inch plasma lg model tv .i bought the sj7 lg sound bar .but can’t seem to connect to tv .it plays music from my phone so I no it works .ive plugged HDMI cable in and nothing .do I need to use another cable ?

A: Hi Horse. What audio connections do you have on your 2013 Plasma TV? The LG SJ7 Sound Bar Flex 4.1 Channel Speaker System with Wireless Subwoofer and Bluetooth Streaming - Black, Model # SJ7 has an HDMI 1,4 Out port and an Optical Digital Audio Out and an HDMI 1.4 In as connection ports. If your TV has an Optical Digital Audio Output on it, you can simply connect that port to the Optical Digital Audio Input on the soundbar using an optical (Toslink) cable if you have one. You might need to go into the audio settings in your TV to specify what path to output the audio through. Check the instruction in your owner's manual for your TV for instructions on that. It should be TV setting menu [ [Sound] [ [TV Sound output] [ [External speaker (Optical)] or something similar. You can use the HDMI 1.4 Out if your TV has an HDMI port that supports ARC functionality. ARC functionality allows you to send audio upstream or downstream through the same HDMI cable when it is supported on both your TV and on the Soundbar. Again, you'll have to get into the audio settings in your TV's menu settings to specify an audio output path. That should look something like TV setting menu [ [Sound] [ [TV Sound output] [ [External speaker (HDMI ARC)]. Details of the TV settings menu may vary depending on the model of your TV...^IFV

Rated 5 out of 5 stars
Great Versatile System, LG!
This LG system was exactly what I have been looking for. All of the TV’s in my home have an area to put a sound bar except my master bedroom – we have a split TV entertainment center area below the TV. With the ability to split the speakers, this works great. See pictures. As for the product itself, LG is back in the game. The sound is quite good though some of the higher sound frequencies could be enhanced a bit. Even with the Sub, Treble, and Bass controls, the treble still needed a little more. PROS: 1. Optical audio, HDMI pass-through. When you have the option for fiber audio out of the TV (and the TV speakers can be turned off), this is the best option soundwise – one that this system allows for. 2. Great bass. Overall clear and full sound. Great for any room in the house. If you’re in an apartment, the neighbors will be asking you to turn it down – it can thump very well, especially when in BASS BLAST mode. 3. SUPER easy setup. Out-of-the-box ready. I plugged in all 3 pieces, powered up the system, and everything was synced immediately. No pairing or other needless processes to get things working. After playing around with the remote (sound preferences, functions, etc), I got it to levels that were quite comfortable in a couple of minutes. 4. The #1 reason (for me) was the ability to split the speakers into a left and right channel. I have 2 areas below my TV in which I can put components, and a full-sized sound bar just won’t fit – and I’m unable to put a full-sized sound bar aesthetically-pleasing in front of the TV based on our setup. This was perfect! 5. The 2 main speakers aren’t completely cordless, and can be limited to 3 wires if LG Audio Sync isn’t used. No one likes wires, but there are 2 power cables (1 to each unit) and the optical cable (instead of HDMI pass-through). If using this configuration, a little cable routing with zip ties will make for a pretty clean installation. 6. The system has an “auto-on” feature. If it recognizes a signal coming in (wired OR BT [Bluetooth]), the system auto-powers up the unit and starts playing on whichever function is actually triggered. To power OFF, you have to manually turn off the unit either with the (a)remote, (b) power button on the left side of the left speaker, (c) via the LG BT app, or (d) after 15 minutes, the unit will auto-shutdown. 7. Uses the latest BT version – BT version 4.0. CONS: 1. Needs some work on the treble frequencies. This is something that can be fixed in the next iteration of SJ# series I’m sure. The highs were only high when I used my phone’s graphic equalizer to amp up that frequency range. It’s definitely not a deal-killer though. It gives me enough treble, but to nit-pick, that’s one area of improvement needed. 2. If using battery-only with the 1-speaker option, the battery will only give you about 4 hours of operation… low by BT speaker standards. NOTES: ** I am connected via Samsung Galaxy S8 & Note8 devices. When connected via BT, I can turn up the volume on my phone to MAX and the number on the LG speaker shows 20. Note that if you use the remote/unit to turn up the volume more, it can be done up to level 40 (MAX). Now if at that point I hit the volume down button on my Samsung phone, it immediately goes down to volume 19. Apparently, the device’s software isn’t quite in sync with the full volume spectrum allowed by the device which I thought was strange. So if I wanted to go higher than 20 volume, I had to do it with the LG remote or left speaker controls. ** BT connectivity was in the normal range of around 30-40 feet before the audio started to skip out. ** Both speakers use small power block adapters but there is quite a bit of thin cord on the speaker hookup side. The subwoofer has no power block – it is a basic power cord that’s detachable. ** The subwoofer fires out the front/back of the unit. Some units fire downwards – this one does not. ** The remote uses 2 AAA batteries. The remote is extremely light in weight. The buttons are soft and do not click. It has great response with the system. ** When powered down, there is a red LED on the bottom left part of the right speaker that remains on. ** When powered up, that same light turns white along with a small LED area on the left speaker that shows what function you are using. When using other functions like volume, surround sound, treble, etc, it will temporarily show that information before showing the current input again. There is no way to manually turn off or dim the white LED display or power lights; however, they are at a comfortable level for me. After 15 seconds of no key input, it auto-dims on its own. It brightens when a key is depressed again. OTHER FEATURES 1. Can be used as a single BT speaker on battery power. This is not very ideal as it shows dirt easily and will tip over easily as well, even with the detachable stand. By itself, it doesn’t pack a huge punch without the subwoofer. I’d go with a unit that’s really MADE to do that type of job. Besides, should you take it somewhere and it get dented or scratched up, then you have one speaker that’s in mint condition while one takes a beating of BT use outside the home – not to mention the fact that if you go on a long trip, it will need to be recharged – and you’ll have to take the power cord for that speaker too. 2. Front-Rear setup. I don’t have that setup at my home, but the remote does offer the option to raise and lower the volume of the rear speaker should you opt to use that configuration. 3. The ability to offer a couple of stands makes the unit look better if propped up, but it can still be tipped over easier than most units. 4. You can only use power cables to hook up the unit (omit the HDMI or optical cables) if you have a “compatible” LG Sound Sync TV which uses BT. Well, I don’t have such a TV by LG that has that technology, so I have to use a trusty optical cable instead. 5. LG offers the “LG Bluetooth App” which will pair up with the device and you can use certain controls like on the remote – but a bit more limited. You can also play songs that are on your phone from the app. I didn’t see a lot of use from the app though. 6. 4 sound modes – adaptive sound control (ASC) which is the default, Standard, Bass Blast, and Cinema. I tend to use ASC the most. 7. Supports LPCM, Dolby Digital, DTS Digital Surround. Overall, a really SOLID system that I would most definitely recommend. LG – Welcome to the party!

A great set up with premium sound
I really like a variety of audio options. I also really like wireless options for home entertainment. A few years ago, we installed a really nice 5.1 surround sound system in our living room, but there are wires everywhere. We were able to get a wireless receiver for our back speakers, but there are still speaker wires running to it. There just isn’t a lot of flexibility. This awesome sound bar setup from LG is quickly winning me over. It’s a nice cross between what I would want for my home office and a nice amplification system for a smaller home theater. Set up is very easy. Each speaker has a power cable. Once you have power connected, you connect the two sound bar speakers to each other wirelessly and then the subwoofer will automatically connect to the primary speaker. From here, you actually have the option to connect to the speakers wirelessly through Bluetooth. This is actually the first test I ran. I connected my iPad Pro to the set up through Bluetooth and played some music from Pandora. The sound quality is absolutely remarkable. It’s clear and crisp and honestly, it made me rethink my home office set up. In addition to connecting through Bluetooth, you can also connect to the setup through HDMI or Digital Optical cable. I do wish there was a little more control over the volume on the subwoofer, but there are a lot of ‘sound effects’ that make it a bit punchier. In general, the sub really adds a nice depth to the sound that a standard 2-speaker setup wouldn’t have. I actually really like this sound bar setup rather than some of its competitors because for the price point, you really get a lot of flexibility with how you want to set it up.
