So, if you were to take out the right earbud and place it on a table, that earbud would go to sleep in about 20 minutes and, when that happens, the left earbud would lose its Bluetooth connection.
The signal is then beamed over to the left earbud. That’s because when you pair your QuietComfort® Earbuds to your phone, tablet, or laptop, the Bluetooth connection occurs between the source device and the right earbud. Yes, just be sure to use the right earbud.
