Hi giipape, we suggest you to visit any Samsung Major service center (Heartland Town Centre and Montreal Service Center ) or Samsung Experience Stores or you can contact Samsung live chat support so that they will file the ticket and send you shipping label to ship your ear buds to synchronise with the new case. You need to use the shipping label to ship the buds and the technician will provide the mode of payment. Here is the link for live chat: https://www.samsung.com/ca/livechat. We are available 24/7.
Hi giipape, unfortunately we don't have the information about the estimate cost. However, we suggest you to contact the Samsung service so that they can help you with the estimate cost.
