The quality and intensity of the sound are many steps above compared to the built-in speakers of the television, so with the usual cost of 80-100 euros, you get very good sound. There is also the smaller model (110) at 65 euros right now, but this specific one (140) has 2 small subwoofers at the ends, so logically it has significantly better bass. It goes without saying that other models with a separate subwoofer will be even better. I chose this one because it has a low height, so it doesn't block the remote control signal. The connection is super easy, you just connect it with the optical cable or HDMI, which is NOT included in the package, and select optical or HDMI audio output accordingly on the TV. HDMI is recommended so you can control the volume from the TV remote, otherwise you use its own, which is not very practical. It also has Bluetooth to play music from your phone. It appears to be a sturdy construction.

UPDATE 27/08/2024: It still works great.
