It takes the sound of a regular lower- or mid-range TV up an order of magnitude to the highest category. The difference is really huge, but you need to use TruePlay tuning and play with the simple equalizer (bass and treble settings). The soundbar plugs into the mains and connects via HDMI to the TV. This takes over responsibility for the sound from the TV, on which the built-in speakers are deactivated. Attention, it is necessary to select HDMI ARC/eARC (for TV without this type of connector, which will not be many, there is an adapter included), thanks to which the soundbar will wake up simultaneously with the TV. That's why it doesn't have a custom controller to turn it on or adjust the volume, everything just works as it has been, except the sound doesn't come out of the TV. In my case, the volume indicator has disappeared from the screen (Philips Android), but I don't mind, I don't need to know if the volume is at 24 or 28. For the best possible result, it's advisable to tune the soundbar via Trueplay in the mobile app (iOS required), so that the sound adapts to the acoustics of the room. The sheer scale of the sounbar is surprising. Even without a subwoofer it can rumble if you want (you can freely adjust the intensity in the EQ), the spoken word is perfectly clear, the music in this category is probably unbeatable. The soundbar connects via a mobile app to WiFi. In it you can then set the night sound, for example, when the depths are suppressed so that it does not wake up the sleepers in the next room, part of the mentioned equalizer, which I recommend to try and find the best settings for the treble and bass component. There is also the option to play only music in one of the Sonos radios in different genres. Mobile playback works via AirPlay from any app. Beware, this is not a bluetooth speaker, so it's not suitable for someone who wants to play their own music from an Android phone. This will only work for TV playback, for example via Spotify/YouTube etc. installed on the TV, which shouldn't be a problem to control with Android. Just play the music on the smart TV. The modularity of the system is also perfect, where you can add other Sonos devices at will, such as rear speakers to create 3D home theatre sound, or a subwoofer, which I don't think is even needed. It also works with IKEA's Symfonisk speakers, which were made by Sonos (but production has been discontinued). The system also supports multiroom, so you can sound the whole house or apartment and play music in individual rooms. It's a slightly more expensive device, but it's worth the quality. The sound is great, it can be expected to last a long time and once it becomes obsolete and wants to be replaced, Sonos offers interesting discounts for new devices. Users without an iPhone should also consider whether this is the right solution for them, so as not to be unnecessarily disappointed. But if your primary concern is to significantly improve the sound of your TV (which is the purpose of the soundbar, after all) and someone with an iPhone can help you with tuning, I don't see a problem.
