The microphone is a weak spot in nearly every headset currently available, even high-end models. This has to do mainly with their small size, which is a compromise to make headsets a little bit lighter and more comfortable. They don’t process some frequencies very well, as deep-voiced gamers often lament. Their bass tones come out as metallic and even a bit distorted. You might be able to adjust this, but not on the headset. Instead, check the game settings. High-performance games allow not just controller adjustments but fine-tuning of headsets, including microphone output.
