They'll sound great for listening, but since they are production/mix monitors they don't have the connections and controls required to connect directly to a PC (not without major usability hassles anyway). They have no digital connections, and they also have no stereo volume control. They are intended to connect to a device that has a monitoring preamp built in, such as a mixing board or recording interface.

So at minimum you would want to a monitor controller, such as the Mackie Big Knob Passive or maybe this one if you want an understated look.

And best case scenario is that you use a DAC (digital to analog converter) that has built in volume control, which will get you a cleaner signal from the PC than you would connecting it to the headphone jack. Something like the SMSL Sanskrit would work well for that... or you could just get an entry level recording interface like the Focusrite Scarlett Solo, which would do the same job and also add some other features you may or may not use.

Per the Q&A on that Amazon page, there’s a slightly nicer version of this available, supposedly with Alps brand potentiometers.

There’s also the Mackie Big Knob Passive as well.
