I have it for a few days! It connected immediately, the TV recognized it from the first moment, and the connection with the woofer was automatic!
It is quite big in size and on my 55-inch TV it couldn't fit between the legs, so it has been placed right in front! A small downside, but if someone doesn't want any cables to be visible, it's good to know.
As for the sound, I don't have much to say! I am completely satisfied with the quality, both in movies where I can hear sounds that I couldn't hear before, and in music! And there are no complaints about the volume, it doesn't distort the sound! It has a relative surround feeling, but it is in no way comparable to a real home cinema setup! Also, I didn't have any issues with the synchronization of the picture and sound.
It includes an HDMI cable with which the ARC functions normally. Therefore, it opens and closes automatically with the TV's opening and closing.
I don't have a comparison measure with other soundbars to say if the price is worth it or not. I bought it and I don't regret it!
I hope I helped..

Incredible soundbar, especially for those who didn't have one before, the difference is noticeable immediately. The pairing between the soundbar and the woofer is done instantly and automatically. For zero loss, I recommend connecting it to your TV with a cable (in the arc position if it's a Samsung TV). With Bluetooth, which I have tested on my computer, I have had no disconnections or delays so far.

To take advantage of Dolby Atmos, etc., you need (for those who download movies) the encoding to listen to it. Don't expect to download a stereo movie and hear Dolby Atmos 5.1, as I read elsewhere. In movies/series that support it, the sound quality is jaw-dropping. Especially the bass makes the whole experience completely different. Even in scenes with intensity or explosions, the dialogue sounds crystal clear and doesn't get lost.

For music (Spotify) and in general, I reached the middle volume, and above (although during non-quiet hours), I was sure that the neighbors would make a remark. It's very loud, without compromising the quality.

For those who don't want to disturb their neighbors at night, there is an option through the app to activate a night mode and make listening safer during nighttime hours. Personally, to not disturb anyone, I lower the bass below zero (-5 usually) because it will definitely be heard even with this feature. (And above all, let's be a little human, it's not their fault).

The app is very convenient, it has simple settings that an average user wants, but also for an experienced user who knows how to adjust.

Finally, this particular soundbar can support Samsung's side speakers for true Dolby surround sound, for those who want it.

One of the best purchases I've made. At first, I was interested in JBL soundbars, but as soon as I heard the Samsung soundbar, I was shocked. Tremendous difference in quality. Clean bass, very powerful sound (I haven't dared to turn up the volume all the way because it would be heard throughout the entire square) and combined with Dolby Atmos, it's the best you can get for this price. When Dolby Atmos is activated and the two top speakers are turned on, you immediately notice the depth and surround sound. I have connected it to Google Chromecast and I also listen to music through it. It has several modes that you should try out to see which one you like the most. Imagine, I have the bass at -2 because if I put it at +2, the whole house will rattle and it may affect the quality. I highly recommend it.

UPDATE: If you notice a delay in sound, it's normal. I also experienced it when I connected the Chromecast to the TV and not to the soundbar. When it was connected to the soundbar, the problem was solved. So, it's better to connect any source to the soundbar and not directly to the TV, even though the soundbar itself has a setting to reduce or increase the delay.

I replaced the Sony HT-G700 400W 3.1 with this one. It is much better in terms of soundstage, with much fuller and colorful bass (which can be dry and abrupt or even noisy with a lot of tremolo). The voice performance is EXCEPTIONAL and with the bass at low levels, it is perfect for everyday use with TV without being tiring even at low volumes. The ATMOS feeling is much better than the SONY HT-G700 as the sound has a hint of movement upwards, but with such a setup, I didn't expect miracles. There is a complete adjustment of BASS, TREBLE, something that the previous one did not have. In musical pieces, it is good and enjoyable without digital distortion of the music with a natural image, something that was missing from SONY, as the sound was very fake and empty without a full feeling. The only disadvantage is the very difficult-to-read screen of the soundbar, but it's not a big deal, maybe the size because it's quite large in length. Bought for 340 euros from a well-known chain! I recommend it as an excellent choice in my opinion!
