I have the X-MIni speakers

And they have the X-Mini Max speakers which are exactly like these ones. I wonder which company did them first, anyway? I've seen like 4 different brands of this design. The X-Mini sounds better than the other models I've seen, but I haven't heard this particular brand.

They sound decent for the size but frankly they are just a last-resort emergency speakers when you just need to have sound around you and have no better options.

In other words, they sound like crap. But that's fine nobody was expecting monster sound from them.
