    After a lot of searching and reading reviews, I ended up with this model from Keff (the lsx ii have double the price and are essentially the same speaker).

    Like all speakers, they need some time. At first listen, I wasn't impressed, but after about 30 hours, the speakers showed their true character. And for their size, they play very well, balanced with clear vocals. Ideal for office and multimedia use, and definitely much better than a soundbar.

    I don't think there is anything comparable in this SIZE that has this sound quality.

    This review is about the colour: Black

    It is a high-quality construction, visually appealing speakers in a convenient size.

    Their sound is very good for their size.

    They easily connect to WiFi and Bluetooth.

    The negative is that although KEF states that they play Tidal with streaming, they do not even do it with the latest firmware version 5.2.

    Neither Tidal connect, through the Tidal application on the mobile, nor through the KEF's terrible application.

    KEF's support does not respond promptly to emails and they respond with evasive answers. I tell them that the problem persists even when I connect them to the OTE router with a LAN cable, and they tell me to change the channel on the router. Ridiculous...

    Never again KEF.

    Excellent speaker. It is a 4.5" speaker with specifications of 5-5.5". It is balanced, with a large soundstage, atmospheric, and not bright. The built-in DSP/EQ settings help you adjust the sound to your space. The subwoofer out DSP has a high/low pass filter. There is also a setting to decrease/increase the volume on the sub from the application, so you don't have to get up to adjust it from the sub. It goes low within its specifications and is fast and defined. The high frequencies are relaxing, although they may lose some body for someone who wants high resolution. It has all the streaming services, easy to use, and very well made. When the network cable is connected between the speakers, it adds a click of "clarity" to the sound, but you can comfortably listen without it. At this price, you get everything in one and stop searching. Personally, it saved me. Note that it is for relatively small spaces. Let's not forget that it is a 4.5" speaker. The iOS application sometimes doesn't respond. When I start the speakers, I have to change the profile I created with the settings to default and then back to mine in order to "save" the changes. Also, I can't delete a profile because the application completely freezes. I read that there are no such bugs on Android, but personally, I haven't tried it yet. Software update version 5.3 on 24/06/2022. All the above issues have been fixed!
