Q&A Why does the headphone's audio quality change when I switch between my laptop’s built-in microphone and my Bluetooth headphones’ microphone?

  • I see that you are using your headset for audio output. Therefore, when you simultaneously utilise it for audio input, its connection becomes saturated, causing it to decrease its audio quality to maintain a connection. Alternative possibilities exist, but I've no reason to believe that they are applicable here, when this problem is so common.
  • A superior Bluetooth controller (usually, one that supports a later standard, like 5.2, is sufficient) on both ends should remediate this.
  • #### A Cause
  • I see that you are using your headset for audio output. Therefore, when you simultaneously utilise it for audio input, its connection becomes saturated, causing it to decrease its audio quality to maintain a connection. Alternative possibilities exist, but I've no reason to believe that they are applicable here, when this problem is so common.
  • #### Potential Solutions
  • A superior Bluetooth controller (usually, one that supports a later standard, like 5.2, is sufficient) on both ends should remediate this.
  • The easiest way to verify is with another set of headphones, then another computer, in every combination of the two possible. Solely then should you consider purchasing a separate PCIe BT card, or new set of headphones.
  • Similarly, a wired microphone would also remediate this.
