Poor audio quality through 3.5mm jack?

Ukrainian_Priest

I recently purchased a HyperX QuadCast S usb microphone as an upgrade from my old Bluetooth headset mic. For those unfamiliar, this mic has a built-in audio jack for your headphones that provides mic monitoring. I noticed in doing so my audio quality dropped dramatically compared to using my usb headset. All highs and lows seem to be non-existent. Bass is flat and it sounds like I'm hearing things through phone speakers. Assuming it was the mic I used my PC's audio jack and got the same results. I've considered alternatives but at the end of the day I want to find out what's causing this. I've spent hours uninstalling and reinstalling drivers, trying different headphones, different cables, different usb ports, disabling all enhancements, and anything I could find on any forums, all to no avail. If anyone has any thoughts or ideas, I would be willing to try them.

If you don't mind my asking, how old is the computer? Also, is any part of the system bluetooth?

The system itself is about 2 years old. The only Bluetooth part of the system would be the usb dongle for my old headset.

It may just be a quality issue. Your old headset may just comparably be that much better. Consider that with a USB Headset, that's essentially its own sound card. It's in no way using your onboard audio. What brand and model as your USB headset?
