Pair two earbuds with eachother

Hello! I have bought Jabra Elite 3 two times, and now I have lost on of the earbuds twice aswell. This means I have to earbuds, one right and one left, but they are not connected two eachother.

Is there any way I can somehow connect them to each other or reprogram them so I can listen to something with both ears. Please tell me if there is a better subreddit for this question and if something I unclear.
