question about a headset

[Squareepants]

does the FIFINE AMPLIGAME SC3 GAMING and DT 990 Pro 250 Ohm work together and I need a mic for around any price below 140$ for that will also work with the fifine

those will technically work together along with any 3.5mm or XLR mic. I'm not an  audiophile so I can't recommend a mic.

No, max 32ohm. check the specs.

it says online that it can support 250ohm 

 

The same story can be found on the 3.5mm monitoring jack, you can comfortably use it with a pair of high-impedance (up to 250 ohms) headphones. You might not need such high-fidelity headphones for gaming, especially since not every gamer would like to enable the sidetone, but it is just good to know that your device can drive one of those high-end gear.
