One earbud won't connect or power on

• 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 

Regardless of the issue you are experiencing with your product, try updating it. Visit btu.Bose.com and follow the instructions to ensure your product has the latest features and enhancements.

In case the left earbud is not powered on, press the button on it. The light on the earbud should glow when it powers on, then it will automatically try to connect to the right earbud.

Be sure the battery is not depleted. For more info see, Checking the remaining battery charge and Charging your headphones.
