Good choice to avoid extra tangled cables, etc.
I use them with a U2412M and a 2014 Mac Mini and I am satisfied with the fifteen euros I paid for them. Personally, I have them set to maximum volume from their own controls, and I increase it from the Mac using the Boom application.

I, because I no longer have the screen, created a special power supply via electricity and use them on my laptop and mobile phone, and they play very clearly and quite loudly for their size!

Given that we are talking about 5W screen speakers, they are excellent. They adapted very easily to the U2412m and look very nice. Their volume is very good, as well as the clarity of the sound they produce. The bass is not that much, after all, bass requires speaker diameter which is not present here. Of course, the performance decreases at maximum volume, as it is normal since we are talking about screen speakers and not stand-alone speakers. If you want them for parties, you are not buying the right product, their job is desktop use, music, movies, and of course, saving space on your desk. The price is also very good for what they offer.

Very good for their price and convenient if you have a Dell monitor because it saves space on the desk. Quite powerful so that everyone can hear within a very large room. Equivalent to those of a medium-sized television, just to have a point of comparison.
