These strings are an excellent student string, usable for a wide variety of styles and needs. A solid core string provides a stiff feel, but a long lifespan (and relatively inexpensive cost). Not a sophisticated string, they will provide stable tuning and a solid, if "non-specific", tone. Will work particularly well on a heavy or thick-topped bass that doesn't respond to lower-tension strings.
