What can one say about these.. little bouzoukis that are the big brother of the perfect ones in the NOD Base 2 Zero category, and at such a price, I don't know if there can be anything better because better cannot be achieved with what they ask for! Their sound is at least honest compared to much more expensive junk, to the point where you can't believe it. I should add here that I prefer the NOD Base 2 due to their sturdiness and size. Here they tried to produce a bit more bass, but they didn't succeed, although overall, if someone compares them to the Base 2, they sound duller. No, they are not hi-end, not even close, but they are very decent for their price! Attention, because the speakers are powered by USB, when the PC or laptop constantly supplies power to the port while it is closed, it is possible to hear interference! This is not the fault of the speakers or any other (big or small) speaker that has a permanent power supply connected to a closed PC. The 50Hz noise usually comes from the grounding loops created in combination with other simultaneously connected devices and leaks! The input of the speaker remains open and collects any parasitic currents that reach it. This applies to ALL active speakers that remain open with a closed PC and do not have proper mute on the sound card output!
