I got them to connect with an audio-technica turntable via cable, but I also connect them with other devices via bluetooth. For a small space, like a room, they are very good for their price.

First impressions: The build quality is top-notch, the sound is quite clear and sufficient to fill the room, however, I haven't tested them (yet) at high volumes. On the downside, they lack in bass, of course, the way you position them in the space plays a significant role, something I haven't experimented with yet.

Personally, I bought them for less than half the price, at €30, otherwise there were other options in the same brand with more W.
They have a pretty good sound, for my ear, I would say they have exceptional sound, just don't turn them up all the way, one click below full volume and everything sounds nice and clear. So, 3.5 to 4 stars for their regular price. At the price I got them, 10 stars and it's still not enough.
Also, the Bluetooth, although version 5.0, seems to have quite a bit of lag and it's not my phone's fault as I have tried it with other speakers. **Correction: I connected them with a Bluetooth dongle to my desktop computer and the lag is minimal. It was the mobile app's fault.** If their price ever drops, then yes, they are worth it, but if it stays where it is, no, as I said, there are other more powerful options.

The build quality is very good!

The downside is that the power cable and the audio cable from the main left speaker are without connectors, directly connected. If the cable gets cut, someone will need to open it to fix it. I think it's a minor issue, just mentioning it. And finally, the front mesh easily comes off for anyone who doesn't want it. When it's in place, it has a distance of about 3-4 millimeters all around, it doesn't fully close the speaker, so it doesn't offer much protection against dust
