First, find the little spy
On wired earbuds, the microphone usually lives in the small control capsule below one earpiece. Let it hang about a fist from your mouth. Record the same sentence once with your ordinary setup and once with the inline mic. Keep the room and your speaking voice unchanged.

The blind listen
Once both takes are ready, shuffle them. If the difference is real, you should be able to identify the mystery recording without peeking at its letter.
The meter reports loudness, peak level, and a rough signal-strength score. It cannot judge warmth, clarity, or charm. That remains gloriously human work.
Record both takes to unlock.
