      Just don't expect it to be incredible

      • Verified PurchaserVerified Purchase
      • My Best Buy® Elite Plus MemberElite Plus Member

      I purchased this item and replaced a Bose Cinemate 120 - which has great sound. The sub on the LG unit is pretty weak, but you can bump the bass and sub to equal out the sound from the bar. I made the purchase primarily for the Atmos feature. I had bought an Xbox One X and wanted the full experience. SOUND QUALITY: The sound isn't bad after you bump the sub to around 4 of 5 and the bass level to the same. It is probably a few steps up from the sound I get from the Samsung TV itself. VIDEO: It does pass the 4k through, but have noticed sometimes it lags. After it starts passing along the video input, the 4k is nice. SURROUND & ATMOS: Don't expect much. It is a sound bar. I cannot hear anything special when the signal is Atmos. Since the speakers are in the top of the sound bar and shooting towards the ceiling, I have wondered if I need to move the soundbar higher. The surround is what you would expect from a soundbar. It is okay, but not like having a system with multiple speakers surrounding you. FUNCTIONALITY: I have it connected to the ARC on the TV, but am using the HDMI output from the Xbox to the HDMI in. When I turn on the Xbox, TV and sound bar, it always defaults to either Optical input (which there is nothing connected there) or to the ARC input. I have to always cycle through the options to get to HDMI in. REMOTE: The remote is simple. It has no lights, so keep a flashlight nearby when watching in the dark. You learn pretty quick where the volume, mute and input buttons are located. I haven't used any of the other buttons yet. I would recommend just programming it into a Universal Remote if you have one. RECOMMENDATION: If you want a soundbar, it is pretty decent. It has some nice features like the 4k pass-through, bluetooth connectivity, etc. If you are looking for high-fidelity, theater quality sound... just move on. However, if you are looking for an affordable soundbar with decent stereo-like sound, this is not a bad choice.

      Probably OK for Most, but not for Me

      • Verified PurchaserVerified Purchase

      First, let me say that I returned it after a few weeks ("Elite member"). It's not a "bad" unit, but IMO, the performance does not justify even the closeout price of $750, that I paid. I purchased an LG OLED55C7P TV last Black Friday and, although I thought that the sound from the internal speakers was adequate, I wanted, perhaps, to upgrade. I also wanted an LG unit to minimize any TV-sound bar integration issues. Some observations: 1. As I recall, set-up was not too difficult. I used the USB-ARC ports on the bar and TV. Using the sound set-up options on the TV required some trial-and-error. 2. Not much treble-bass adjustability. There are just 5 or 6 (?) pre-set sound modes to handle this. There might be something else, hiding somewhere, but the documentation, like for most consumer electronics these days, is minimal. 3. If you place the soundbar on a table in front of the TV, it covers up the IR receiver on the TV. Accordingly, had I kept the soundbar, I would have had to raise the TV about 2 inches. As it was, I kludged it by wrapping a piece of aluminum foil around a small block of wood, placing it at a certain angle between the bar and TV and bouncing the IR signal off a certain spot on the ceiling to the foil and then the IR receiver (whew!). It did work. My wife hated the klunky appearance of the wood bar. 4. The integration that allowed my FIOS remote to control both the TV and soundbar usually worked, but at least a few times, the mute button would not un-mute the sound. I had to turn the bar and TV off and on to recover. 5. There may have been some lip-sync problems with certain content, but I was never able to really nail it down. 6. Certain reviews, that I read, spoke about the bass being "muddy". Not sure what they really meant, but maybe it means bass that lacks some clarity. May be true here. In summary: Not enough improvement in the sound and using it sometimes was a bit too "fiddly" IMO to justify the expense. Actually, there may be integration issues with any soundbar. The TV, on the other hand, was definitely worth the expense. Maybe I'm just not as critical of sound as I am of TV picture quality.

      Can't go wrong with a lil know how

      About the bar? Scroll down to all caps section to skip the story! I purchased this open box. Returned it for a Sonos. Big mistake. Sonos ecosystem wasn't for me. No bass. Forced phone useage. It would be awesome with enough money in it. But then wouldn't most things? So tried to get the open box couldn't do it. Went to 4 different best buys could not beat the deal I originally found it for. Went back a second time told my story of my mistake and wound up getting the sound bar back. Thank goodness. ABOUT THE BAR 5.1 channel Dolby 500 watt (do note 5.1 channel is considered 5.1 because two up firing speakers you have to be in movie mode to use them) It has good atmosphere in my man cave. 14x14 room. It will blast you out. Finding content that is Dolby makes it come to life BUT not perfectly. Researched a ton found that specifically the LG H3 H5 AND H7 working the LG music flow app on my Android phone would configure THIS BAR (SJ9) NOT (SK10Y or similar K models) to work with rear speakers. Avoid the LG SJ4 speakers they DO NOT work. All of the negative reviews for the H series speakers are typically older LG fixed all the drops and syncing issues. You too can have a true multispeaker setup with this bar and the LG music flow app. ENJOY! PS. I have this setup with a Samsung TV and tried using radiant 360 speakers R3 handle the rears. It won't do it. You need a Samsung 7 series or better sound bar to do the rear channel processing and I have a 9000 series Samsung TV so if anything would have done it it'd been that one.

      Meets my expectations ($100 off retail)

      • Verified PurchaserVerified Purchase
      • My Best Buy® Elite Plus MemberElite Plus Member

      I wanted a decent-sounding soundbar + subwoofer system for under $1k (tax included) to work specifically with a LG C7 tv for streaming movies, tv shows, music (Apple 4k tv) and a gaming console (PS4 pro) to provide audio for a 300 sq ft room with a ceiling height of 10 feet. I was not after a "smart" speaker system, rear surround speakers or anything to produce that effect, a "real" Atmos sound effect (for that, we go to the movie theatre), a bass module that produces a real strong bass sound, nor a system that will sound awesome at 100% volume. So this review is only limited to the above parameters. People have different sound preferences. For me, I was not disappointed. At $100 off retail, it was now worth it. I believe they just dropped the price to $850 now. There are tips: - use an appropriate HDMI cable (I got mine from Amazon for less than $8) - place the wireless subwoofer away from your other wifi gadgets. The woofer's audio started to cut in and out every two was annoying...but I noticed this only after I positioned the module closer to my other gadgets (wifi router, wifi security camera base). Lo and behold, the interference happens every time I moved the module closer to those two gadgets. I don't hear interference at 3 feet. - you can adjust the sound effect (Movie and Bass Boost are the best) - you can adjust the treble and bass - I said those two points because you cannot play around with those settings when auditioning the bar at a store. Being able to do so makes content sound much better than the "Standard" setting Why 4 stars only? I'll update this review in a few months as there have been a small number of reports of units malfunctioning months after purchase.

      we have been waiting for this sound bar to come out and we ordered it on line from BB it arrived in perfect condition we hooked it up to our 65 in LG-SUHD 8500 and WOW everything linked right up without a hitch using HDMI ARC sub also linked up on the first try NO complex setup with this bar we just ran the updates and bang it was ready to go we put in a 4k movie with atmos and the bar says we were in atmos no guess work there the sound was fantastic and the sub set at 2 shook our hard wood floor ,,,no kidding.voice is strong and clear and with the bar set at just 20 is LOUD and goes way up from there and still sounds great atmos seems to work well but with most its just an effect and will be different in every room our living room is open to the kitchen and this bar fills the room no problem as far as we are concerned this bar is a keeper LG took there time and put out a solid bar it`s thin to only 2 1/4 inches but puts out great sound and looks good to a bit pricy at 999 but worth it compared to the Samsung and this bar covers DTS,ATMOS,TRUE HD and more we are happy with this sound bar....thanks LG

      Good sound but not the best

      • Verified PurchaserVerified Purchase
      • My Best Buy® Elite MemberElite Member

      This review is actually a combination of review between TV SJ9500 and Soundbar SJ9. Overall I'm very satisfied of this product an I definitely recommend it when purchased in combo with an LG TV due to the promotion on-going at Best Buy. The sound is well balanced, good bass and clear voices. There are few presets for MOVIE/MUSIC and some others, however I always find myself to prefer the default. The Soundbar is sleek and very nice to look. I personally find the look and feel at very high level and its shape fits very well my living room. This new LG SJ9500 spot an amazing 10bit display with brilliant colors (8 bit full Chroma 4:4:4 or 10bit 4:2:2 or even 12bit 4:2:0) and pretty decent luminosity. While it is ideal for living area is not quite decent for dark room/media room since the light bleeding can be very annoying, reason for not giving full 5 starts. Overall I'm very very pleased of this TV, I really enjoy the HDR and Dolby Vision movies on Netflix, Vudu and Amazon. I did pair it with the LG SJ9 and I should say it was a great buy due to the promotion on-going I saved 300$ on the SJ9 and I could not be happier with the ratio quality per bucks. The SJ9 supports Dolby ATMOS, however only VUDU is capable to bitstream the ATMSO to the soundbar at this moment. Netflix does not support it! So disappointed! I spent quite some time with Netflix support and they insisted that the TV must support ATMOS to be able to bitstream the audio to another device, which does not make sense for me. I pointed out that Vudu does that, but seems they did not care much.

      Great soundbar if you know how to use it

      • My Best Buy® MemberMember

      I would like to say first that this sound bar is awesome, which for $800, it really should be. BUT you HAVE to do your research on this unit. In order to use this soundbar to its true potential, A. You need an HDMI cable, either going into the soundbar, or using your TV's HDMI ARC connection. B. You're gonna need a BluRay player that decodes DOLBY ATMOS, I bought a used Xbox One S. C. You're going to have to find movies that offer ATMOS. I found a list online that listed all the REGULAR BR that are ATMOS and UHD BR that are ATMOS. There is no doubt that your regular movies, even if you aren't using true ATMOS settings, will sound better. But if you're getting a $800 soundbar, you're gonna want to use it to its potential! Moral of the story, don't pay the full $900 for this sound bar, at the moment when there really isn't widely used content. I got this sound bar in a bundle package for around $700 and I still haven't found a movie that I found myself going WOW. I would suggest a good Mid-Range soundbar if you don't need the "Bells and Whistles"

      Excellent sound system!

      • My Best Buy® Elite Plus MemberElite Plus Member

      Purchased this particular unit after lots of reviewing and comparison to other top end brands. Not only was it half the cost of other high end sound bars with subwoofer addons, but also boasted the Dolby Atmos capabilities most others did not. Setup was mostly easy. Started with an HDMI pass through from devices to receiver to sound bar then to TV. I kept getting issues where my receiver and sound bar would randomly shut off while watching shows, and always at the same spots. Most likely an issue with so many pass throughs, as once I switched to the optical cable connection from my TV, worked perfectly. Highly recommend turning on the “auto volume” function. I found I needed to set it at 30+ (max is 40) to hear dialogue. Once I turned that on, I can set it to 12 and the balance between voice and effects is perfect, and it helps accentuate the surround capabilities, which are surprisingly good without additional rear speakers. I will eventually add the wireless speakers for rear sound. But even without, this bar is amazing to use!
