It's a bit all over the place. For little monitors in this size/class, it might be the best I've seen. Definitely better than the PreSonus Eris 3.5 and Mackie CRX3 I tested earlier this year. But those two products are terrible so saying that the MR4 is better isn't necessarily as good as it would otherwise sound.
Lets imagine, you have not much money, and like easy decent sound on you PC. What would you say?
