Microphone does not pick up sound | Bose Sport Earbuds
If only using one earbud, make sure to use the right earbud.
•The right earbud is the "primary" or main earbud; it controls the left earbud by relaying audio from the source device. If you place the right earbud in the case by itself with audio streaming and close the case, audio will stop, and the earbuds will turn off.
•The right earbud also has the microphone for phone calls. Make sure you use the right earbud for phone calls.
Be sure you're wearing the earbuds correctly.
