Reply to comment by blargh4 in Trying to understand impedance and why one headphone gets louder than the other. by extremeelementz

I’m sorry yeah I was just assuming the mobo has a slightly better output than the standard front panel jack. I’m still learning and trying to figure things out and kind of lost.

Well, understanding this stuff is basically a chapter of an introductory electronics textbook, so that's understandable.

The front panel jack connects directly to the motherboard. It's intended for headphones, so that should be the right place to connect them. It's possible the rear output will also detect that it's a headphone and connect it to the appropriate amp, but I think it's likely to have the same capabilities. There are also line-level outputs, which *may* give you more voltage than the "smart" headphone jack, but they can't drive much current so I personally I doubt you'd get better results with low-impedance IEMs. These audio chips are fairly complex, they mix multiple functions for each jack, and I don't think you can easily find a spec sheet for them, so unfortunately I can only guess.

So wouldn’t the front headphone jack that’s plugged into the mobo with a small pin connector be less amplified compared to the sound port that’s soldered directly to the mobo on the back of the computer where the audio chip traces to?

Nah, assuming the connectors aren't damaged/corroded, the electrical effect of that bit of extra wire is absolutely negligible at audio frequencies/headphone power levels.
