I second this from the previous poster: On Windows 10, changing the recording frequency of the input device didn't do anything for me. As odd as it sounds though, changing the output device from 48kHz to 44.1kHz DID fix the problem. Not sure why (driver issue perhaps?), but making that change fixed the issue of my voice being super deep when using the UX2. Confirmed the fix in a voice call with someone where I switched the setting back and forth. Whenever my UX2 output device is set to 48kHz, the input device sounds super deep, but when the UX2 output device is set to 44.1kHz, the input device sounds perfectly fine.
