Start with a simple audio setup
Play one reference sound and record a short impression with a comfortable volume. Headphones can keep the reference from leaking back into the microphone. Avoid holding a loud speaker next to it. Distortion in the reference and distortion in your recording are different problems; note which one you hear.
Compare wired and Bluetooth audio
Bluetooth headsets can change audio routing when their microphone activates. Compare one attempt with the device microphone and another with your headset. Keep your distance and volume consistent. This comparison helps identify a routing problem; it does not guarantee identical behavior across phones or Android versions.
Check competing microphone apps
Temporarily leave a Discord call or close another recording app, then retry the same setup. Another app can hold audio focus or the microphone. Report your phone, headset and whether the issue disappears without that app. We have not verified every Discord and Bluetooth combination and cannot promise universal compatibility.
