No, you do not need both Bose earbuds to connect. Some Bose earbuds, such as the QuietComfort Earbuds II and Sport Earbuds II, have a feature called Independent Single-Bud Use that allows you to use either earbud independently.
To use either earbud independently, simply remove the earbud you do not want to use from the charging case. The earbud that remains in your ear will continue to play audio.
You can also use the Independent Single-Bud Use feature to switch between using one earbud and using both earbuds. To do this, press and hold the Multifunction button on the earbud that you are not using. You will hear a voice prompt that says “Single-Bud Mode.”
The Independent Single-Bud Use feature is a great way to save battery life or to listen to audio in a more discreet way. It is also a good option if you only have one ear that is working properly.
However, there are some Bose earbuds that do require both earbuds to connect. These earbuds typically have active noise cancellation features that require both earbuds to work properly.
If you are not sure whether your Bose earbuds require both earbuds to connect, you can check the product documentation or contact Bose customer support.
