I bought this specific soundbar mainly for movies, but I also tried it for music.
It connected via HDMI 2.1 certified cable from the HDMI 2.1 eARC port of the TV to the eARC port of the soundbar, where I tested it specifically in Dolby Atmos (I mention these for the reliability of the test) along with everything else. Now, for Dolby Atmos, it is definitely not pure surround, which is perfectly logical, but it does a pretty good job with nice, clear, and powerful sound. The bass from the woofer also does a great job. Surely, if it was separate, it would do a better job, but even as it is, it remains very powerful and satisfies me completely personally, so when it comes to movies, we're talking about a clear upgrade from the TV sound.
Also, for music, it is perfectly fine and very powerful in general. The volume at 30 is perfectly fine to loud enough to give you a good impression.
There is no screen to see what you're pressing, but from what I've seen, it's not a problem at all. If you press something, the LEDs it has light up, so you somehow know that what you wanted to happen has happened.
When playing Dolby Atmos or DTS, the corresponding indicators light up on their own, so you immediately recognize it.
Also, no problem with Bluetooth.
The connection was made with a Sony TV, and it is fast and trouble-free. I haven't noticed any issues so far in terms of connection. The TV I have is 55 inches, so the soundbar fits very well underneath and goes inwards.
The remote control is nothing special, but it does the job and has some presets that seem to work well.
I bought it for 219, so in this price range, there is nothing comparable with Dolby Atmos and eARC support. It's definitely worth it, especially considering the current prices

Positive
Very good product and reliable for progressive/house/techno music and movies.
Improved sound and subtitle acoustics during movie screenings.
The subwoofer enhances the bass when listening to music and streaming from Spotify (fair for 2.1 in small living rooms).
Significantly improved my experience when listening to music with a fuller sound and songs that have punch and low bass.
You can hear more instruments and sounds in a good performance (e.g. vinyl). Overall cleaner sound, but without needing to demolish the house, as it achieves good surround sound in a 35 sqm space and the wall doesn't crack (unlike self-amplified systems). You can be heard outside the door, but not at a level that the neighbor would notice!
Ideal for behind the TV.

Negative
The TV furniture needs to be wide or the TV needs to be over 55 inches for it to fit well underneath (at 50 inches, it barely fits on its legs).
Also, a major drawback is that the Bluetooth turns off after a while and you have to get up to reactivate the soundbar with the remote, as there are no indicators on the screen or continuous LED lights in the menu.
If you place it in front, the TV signal won't reach...if you place it in the back, you'll have to get up and turn on the soundbar when it turns off (a bit annoying). If you hang it, it's an ideal choice that solves the above two minor issues.

Overall, for its price, at half (250 euros) which I bought it, it is a very good choice for Dolby Atmos XP. It took me from a 5...to a 7-8.
