A:AnswerI had the same issue when I lost one earbud on a plane. I was unable to get a single earbud replacement. But at this price the full replacement is not bank-breaking. Also, I use the original case as additional battery source to get even more than the 10 hours of life on a single charge.
A:AnswerForget the earbuds in the device you don’t want it to connect to or you can also just turn off Bluetooth in the device you don’t want connected :)
A:AnswerMine last about 4 hours or so. If you want to extend the battery life then download the app and turn off the noise canceling feature. This will extend the battery life.
