A:Answergo to the store that you purchased it . Maybe they can pull up the receipt if you have an account with them. Best Buy did it for me. They gave me a number to call for replacement. It has a 1 year warrantee Mine was 9 months and they cheerfully replaced it. This really is a great product. I used mine very hard for those nine months.
Hope this helps
A:AnswerI am not sure about the mic but I have a pair of wired Bose earbuds and the volume control and pause/unpause button works just fine with this adapter so I would think the mic would work as well.
