Compared to the rotos (rs665ld) that I normally use, these strings are in my opinion really, really bad. They have almost no output compared to my regular rotos, and whatever output they do have, is way to boomy and with practically no "zing".
They claim to be steel strings, and sure, the material they are made from is probably steel in some way, but they do certainly not sound like steel strings.
Im kind of disappointed, but they are cheap strings, so I can't really complain to much. One thing is certain though. I'm not buying these again
