One earbud won't connect or power on | SoundSport® Free wireless headphones
Clear your Bose product memory of previously-connected Bluetooth® devices.
Your Bose product remembers the last several devices it connected to so it can quickly reconnect to them. In case there is an issue with the device memory, clear it and then try to reconnect the device. For more info, see Clearing the product memory of paired Bluetooth® devices and Connecting a Bluetooth® device.
On the Bluetooth® device, remove all entries of your Bose product from the Bluetooth menu. Then, try connecting again.
In the Bluetooth menu of the Bluetooth device, you'll find a list of Bluetooth products that have been previously connected. Your Bose product might show up one or more times in the list (i.e. it might be listed a second time with \"LE\" in the name). Select each entry for your product and remove it by selecting Forget, Unpair, Delete or something similar. After, try connecting again. For more info, see Connecting a Bluetooth® device.
Use the right earbud if you're using only one.
The right earbud connects to your personal device (phone, tablet, or computer) and transmits audio to the left earbud. Placing the right earbud in the case will stop audio playback. Always use the right earbud when listening to audio or making phone calls with a single earbud.
Check for and install any available product updates.
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.
Press the button on the left earbud to be sure it is awake.
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.
Check if the battery is charged.
Be sure the battery is not depleted. For more info see, Checking the remaining battery charge and Charging your headphones.
Reboot the Bluetooth® device.
Electronics, such as cell phones, tablets or computers, might need to be reset on occasion to correct minor issues. This is typically done by shutting down the device, then powering it on again.
