I bought these speakers to connect my guitar processor (Boss ME90) and to listen to the music. Music sounds good, guitar too.
On default level, hiss from twitter is barely audible from arm length distance.
Volume level is adjustable, so white noise from twitter can be reduced even further.
Bass is reproduced not perfectly, but not bad at all. They are tracks where bass sounds a bit boomy. Probably not very good produced tracks. I had the same effect in my previous HiFi in those tracks.
I had Iloud MTM (only one) to compare. MTM had better bass, even in those boomy tracks but hissed much much more. It's output was also too big for ME90 (too loud).
As my first more expensive studio monitors/computer speakers they are pretty good. Probably I will go for something bigger in the future, but now they stay with me. :)
