Let me just start out with I'm replacing a full home theater system due to opening up the room and no longer using crown molding to run all the wires around the room. This was a full system (1700 w) of front and front highs, two surround, two rear, center and a 250 a sub. Not that I could ever use all the power but it was very nice for a 14' x 17' room. I like it! Great sound for a sound bar, especially since it supports Dolby atmos. I chose this over the Bose LS 650, Enclave and Sonos. I do have Sonos in my home but do have the Sonos connector which uses an optical connector. I'm going to hit the negatives first, this way if you see something you don't like you can stop reading. Samsung should offer speaker stands for the rear speakers, mostly due to all the slim universal stands do not accommodate running a power cable through the stand. Although wire ties or velcro works. Also the sound bar itself is very wide, it doesn't fit between the stands of my 75", being in front means I need 20" of depth to support. TV is set up in corner so a wall mount is out. Will be making my own cabinet. See pic. Another negative is that it doesn't support eArc (yet supposedly coming soon). There are lip sync issues when attempting to hook all your devices to the tv and use the Arc hdmi to provide the audio to the soundbar. Using the smart TV functions seem way better and not that bad. But when running a cable box or game console there is a noticeable difference. I didn't spend a ton of time with the delay options. I purchased the Sanus - 28 to 42 inch stands. They come with a flat top option which works (maybe not with small children) with double sided pads. See pic. Another negative is no mic to assist with setting up channel volumes. Another negative is only 2 hdmi inputs. Which is ok for me since I only have the cable box and a xbox which also plays blue rays. What works and are positive. Setting up is very easy, just be sure to follow the sequencing when powering up the speakers this way you will not have any connection issues when syncing the speakers and sub. The remote works well once you get used to it. The smart things app could use a few more features for setting up the sound and wifi. Which also makes it easy to do updates. There are a few sound modes. Adaptive which is supposed to change based on the input. I only find this useful in the later hours when you need to turn the volume down. The voices seem to be isolated so they can be heard. Standard is what it is, just standard Surround seems to be the overall best for anything that is 5.1 or better. Game mode pro works very well, even for fps games. There is a virtual mode which seems to work well for sound that needs a boost with using all of the channels. Overall performance is great, remember this is a sound bar not a full home theater system. Although it might outperform some on the market. The sound is very clean and what you would expect from Harmon Kardon. even though it only has a little over 500 watts it seems like much more. I have only turned it up a little under half way and it is loud, clear, and pushes the sound through out the room. I don't have any issues with the separation between the channels and can hear the sound move around the room very nicely. I watched Avatar, Jack Reacher movies over the weekend and was impressed. I use my xbox for Prime, Netflix and Disney Plus which is way better than using the smart TV apps (no lip sync issues as long as run through the sound bar). I haven't tried any true Dolby Atmos on blue ray yet but looking forward to it. I did some research and Prime and Netflix do support some shows in Atmos and they sound great. The sub is more than enough for a mid size room. I know this was a little long but I think I hit everything I needed to. I'm very happy with my choice. Would a full home theater be better? Possibly, but you would need to deal with wires, mounting and needing space. Also be willing to spend more than the sale price of this system.

Fits perfectly in my living room, great sound from all the subwoofers. Super easy setup, really can't complain. Also has some perks if you have a matching Q90R TV!

Easy setup and works seamlessly with my Samsung Q70 TV. Superb sound in my large great room. Connects to my iPhone so I can play Apple Music through it if I like. I got stands for rear speakers (just one actually). Also, Best Buy’s price matching policy is awesome. 3days after I bought it Amazon emailed me a price drop of $500. I contacted Best Buy through chat and the agent refunded the difference to my CC in about five minutes. Wonderful. Will certainly be doing business with Best Buy into the future.

I purchased this to complement my Q900, however, after doing a thorough side by side with my Playbar, discontinued play 3’s as my rears, and the sub set up in my entertainment room I found that my current set up sounded much clearer and crisp than this soundbar. I was set and prepared to enjoy the Atmos experience with this playbar, however, even with adjusting the different sound modes something felt a bit empty with the sound. I connected it using WiFi, HDMI, and optical to properly see if I was missing anything, however, unfortunately decided to return it.

I paired this with my Samsung 85” TV and it is perfect. Sounds better than the previous Samsung atmos soundbar. Highly recommend it. No issues with it whatsoever. Very pleased with my purchase!!!
