This & your other question really get the same answer.
You key point is that the mic is Low Impedance.
Most pro mics are.
Consumer mics, however, those typically used for headsets &/or Skype etc are High Impedance.. & that's where the issue lies.
A low impedance mic in a high impedance socket will sound like pants ;)
That's why you need an impedance-matching transformer. However, by the time you've shelled out the 25 or so bucks for one of those, you may as well pay the extra 10 or so & get a proper external USB 'soundcard' system designed a) for low impedance mics & b) which will have a far better mic preamp than your computer.
Even the very cheapest - maybe 35 $£€ or so for a decent entry level one, will totally out-perform the one in the computer.
Check out which you'd like - not on eBay or Amazon, but on a 'music shop' site. They will already be selling only the type that will be useful to you, less likely to be mixed in with high impedance consumer stuff. [You can buy it where the heck you like once you've figured out which you need, but a music shop will set you off in the right direction]. I'd probably suggest to get one with phantom power as it's pretty much a free add-on & might come in useful if you ever use a condenser mic.
Thomann are a large EU music 'box shifter' so they're a reasonable place to start. I can't recommend anything specifically right down at the low end of prices, I've never used anything below about the 150 mark, by which time they're pretty decent all-round. I see they've got an entry-level 'cable that does it all' type thing for €13… no idea whether it's any good, but it's certainly cheap ;)
Late Edit
I only just looked up that specific mic - yes, I now know I should have looked it up first ;)
That's a bit of an oddball, as it's a stereo mic, terminated in twin 3.5mm mono jacks. Some odd 80s home hi-fi thing that is a mis-match to most modern gear.
That means you going to need a stereo-capable pre-amp & also some plug converters to get it into that. Because it's unbalanced & a mic pre will be expecting balanced, you might also need one that can share the input between mic/line/instrument, which might better cope with it being an unbalanced source.

By the time you've bought all the bits necessary to get that to interface with your computer, then unless you actually need stereo, I'd save your time & money & buy something like a Blue Yeti instead. Simple half decent consumer-level mic to USB, all in one.
