If you're using one earbud, make sure your firmware is up to date.
If you cannot hear sound when using only your left earbud, your firmware might need an update. When the product was first released, only the right earbud could be used on its own.
Useful information:
• To use the left earbud on its own, update to version 1.3.26 or higher.
• The right earbud has the microphone, so be sure to use it for phone calls.
